Gypsum board is the name fora family of panel productsconsisting of a noncom-bustible core, primarily ofgypsum, with a paper surfacing on the face, backand long edges.

The popularity of gypsum wall-board results from a numberof factors. It takes virtuallyany decoration — from paintor textures to vinyl andpaper laminates. It also lendsitself to creative shaping ofinterior surfaces, allowingmaximum design flexibility.Gypsum wallboard is aneconomical alternative toother products. Because it islightweight, it is easy to han-dle for speedy installation.With its natural properties, itis durable yet easy to repair.In addition, gypsum wall-board’s fire resistance andsound-control capabilitiesfurther demonstrate its desir-ability in building systems.

National Gypsum produces its wallboard with 100%recycled paper on both theface and back.

National Gypsum’s wallboardis available in a variety ofedge configurations. Thetapered edge provides amonolithic surface and easyjoint finishing.

National Gypsum Companyfeatures a wide variety ofgypsum wallboard productsand accessories for the man-ufactured housing industryincluding 1/2" High StrengthCeiling Board, Seaspray Hi-Strength MVR, regularwallboard, Fire-Shield wallboard and Durabase.

METRIC CAPABILITIES

The federal government hasmandated that each federalagency make a transition tothe use of metric units in allfederal procurement, grantsand business-related activi-ties. National GypsumCompany, in complying withthis order, provides a full lineof wallboard products in“hard” metric dimensionswith regard to width andlength. Standard boards havea width of 1200 mm and alength of 3600 mm. Speciallengths are available on aspecial-order basis, whichrequires minimum ordersand extended lead times.Contact your local NationalGypsum Company represen-tative for further information.Thickness of wallboard willbe “soft,” converted to themetric equivalent.

ENVIRONMENTALCONDITIONS

Maintain a room temperatureof not less than 40˚F (4˚C)during application of gypsumboard except when adhesiveis used for the attachment ofgypsum board. To promoteeffective bonding of adhesive,joint treatment, texturingand decoration, maintain aroom temperature of not lessthan 50°F (10°C) for 48 hoursprior to application andcontinuously thereafter untilcompletely dry.

RECOMMENDATIONS

� When a temporary heatsource is used, the tempera-ture should not exceed 95°F(35°C) in any given room orarea.

� Maintain adequate ventila-tion in the working area during the installation andcuring period.

� Protect gypsum productsfrom direct exposure to rain,snow, sunlight or other excessive weather conditions.

LIMITATIONS

� Recommended spacing of theframing for 1/2" regular and5/16" wallboards is 16" o.c.

� Maximum spacing of theframing for 1/2" High Strength,5/8" gypsum wallboard andSeaspray Hi-Strength MVR is 24" o.c.

� Partitions should not be usedwhere frequently exposed toexcessive moisture unless allsurfaces are waterproofed.

� To prevent weakening due tocalcining, gypsum wallboardshould not be exposed totemperatures over 125°F(52°C) for extended periodsof time.

� Wallboard joints on a singlelayer shall not occur within1/2" of the corners of doorframes unless control jointsare installed at the corners.

SEASPRAY® BRAND MVR TOUCH-UP PAINT SYSTEM SPECSSeaspray Hi-Strength MVR

Ceiling Panels, like anyother prefinished product,can be scuffed or damagedduring handling and instal-lation. Most touch-up canbe avoided with closesupervision and constantfocus on minimizing damage through correcthandling and installation.

IN-PLANT PROCEDURES TO REDUCE DAMAGE TOSEASPRAY HI-STRENGTHMVR CEILING PANELS:

� Use forklift extenders tounload trucks and moveSeaspray units into theplant.

� Do not drag one board overanother or down the ceilingjig.

� Do not drop one board overanother unless both arealigned like pages in a book.

� Care must be taken by plantpersonnel while bringingitems into the home.

WHERE SEASPRAY MVRTOUCH-UP IS NEEDED:

� There are two types ofSeaspray MVR Touch-Uppaint available: aggregateand non-aggregate. Each istinted to match the boardproduced at that particularmanufacturing plant.

� For best results, keep paintand board manufacturingdates within three months of each other. The touch-uppaint should be stirred thoroughly before use.

� Before use of either paint,look at the damage anddecide which paint wouldwork best. If only a smallscratch is involved, the non-aggregate paint will workwell. If major scrapes ordamage is involved, theaggregate paint is normallyneeded. With textured paint,the foam covered roller(such as Hyde Tools part #30430) or a small brush willapply the paint satisfactorily.

� Best results are achieved bycovering only the damagedarea. Do not repaint majorareas of the panel unlessnecessary. For very smallscratches, use the corner ofthe foam roller or a smallartist’s paintbrush. For largerareas, use only as muchpaint as is needed. If care istaken to only touch-up theaffected area, normally it isnot necessary to scrape offadditional texture around thedamaged area. If all textureis gone from an area, two orpossibly three light coats willproduce the best results. Donot try to apply one heavycoat, as this will be readilyvisible after drying.

REPAIR PROCEDURES

Minor Cracks With No TextureLoss: Using a small brush andbrushing perpendicular to thecrack, force the coating intothe opening. Dabbing thecoating with a fingertip is anacceptable alternative.

Minor Scratches With MinimalTexture Loss: Lightly dab thecoating on the scratch witha small brush.

Major Cracks Aligned To TheLinear Texture: Scrape off anominal 1" wide path of thetexture the length of thecrack. Fill the crack with asetting compound or aputty-type caulking com-pound. Allow to dry. Looseboard at the crack mayrequire backing up andrefastening to a framingmember. Reapply the textureas needed with SeasprayMVR Touch-Up and roller.

Major Cracks PerpendicularTo The Linear Texture: Same as above. You mayuse a brush if texture loss isnot very wide.

Major Texture Loss/Paper And Core Not Damaged:Reapply the texture to thedamaged area using the rubber roller. Roll out thecoating in the machinedirection to align the newtexture in the same directionas the original.

Major Panel Damage/SurfacePaper Torn, Exposed GypsumCore, Holes Through EntirePanel: Fill the area with a setting type compound andsmooth the surface with aputty knife. Scrape the textureoff the panel in the areaimmediately around thedefect. Allow to set beforetopcoating with SeasprayMVR Touch-Up paint. Use aroller or a brush as needed.An alternate method is to fillwith caulking compound.Allow to dry before coating.

CLEANUP

Tools may be cleaned withordinary tap water. Use amild soap solution to cleanhands, brushes and rollers.

1/2" High Strength CeilingBoard gives manufacturedhome builders an alternativeto 5/8" wallboard for ceilingconstruction. A specially formulated core providessuperior sag resistancerequired for parallel installa-tion to trusses spaced 24"o.c., especially when water-based ceiling textures areapplied. Since 1/2" HighStrength weighs less than5/8" wallboard, the lowerweight means additionalbottom-line savings.

� Meets HUD ManufacturedHome Construction andSafety Standards — promotessecurity for the homeowner.

� Lower weight of 1/2" wall-board, compared with 5/8",reduces the total weight ofthe unit and provides easierhandling.

� 1/2" High Strength CeilingBoard can be used in place of5/8" wallboard when appliedwith foam adhesive to theceiling trusses. The specialcore exhibits sag-resistantproperties that allow for parallel installation to trussesspaced 24" o.c. It is approvedfor non-fire rated ceilingassemblies where trusses arespaced no wider than 24" o.c.and ceiling is finished withwater based spray textures.

Thickness: 1/2"ASTM permissible variations:In the nominal thickness of+/- 1/64" (0.4 mm) with localvariations of +/- 1/32" (0.8 mm)from the nominal thickness.

SAG RESISTANCE TECHNICAL DATA

The sag resistance for HighStrength Ceiling Board is equivalent to that of 5/8" type X wallboard. Under the strictASTM C 473 Physical Testingfor Humidified Deflection,National Gypsum 1/2" HighStrength Ceiling Board exhib-ited average sag-resistantqualities equivalent to 5/8"type X wallboard. In a testwitnessed by an independenttesting agency, 1/2" HighStrength Ceiling Board exhib-ited an average sag of only0.033" (approximately 1/32")on joists spaced 24" o.c. withspray texture applied. The testwas conducted over onemonth at temperaturesbetween 66° and 79°F with arelative humidity between30% and 60%.


Foam Method: After ceilingtrusses are placed on the gyp-sum board, foam adhesiveshould be applied as recom-mended per the manufactur-er’s instructions.

Staple Method: Staples (16gauge with 1" crown and 1-1/2" legs) must be spaced4" o.c. around the perimeterof the board, either parallel orstitched, and 1/4" in fromboth ends. Screws in the fieldof the board should be 1-1/4"to 1-1/2" drywall screws withmaximum spacing of 12" o.c.Tools must be properlyadjusted so screws, nails andstaples are driven straight andflush with the board surface,without breaking the facepaper of the gypsum board.

Insulation should not exceed2.2 lbs./sq. ft. (10.7 kg/m2).

Note: To minimize foam leakage, the back of eachjoint may be taped with 3/4" masking tape prior toapplying foam.


TOUCH-UP

Fill gouges, nicks, hammermarks, etc., with joint treat-ment compound. Sandsmooth before applying finalsurface texture or finish.Panel replacement may benecessary if damage cannotbe corrected satisfactorily.

Joint Finishing

1. Stagger joints over wall areawhen hanging gypsumboard. Avoid butt joints. Usefull-size pieces of gypsumboard, cutting or routing outdoor and window openings.

2. Consider using paper jointtape for joints on walls. Withthis type of tape, the jointarea is mudded first, then thetape is “bedded” and excessmud removed. After the firstcoat is set, a second coat isapplied to cover the tapeand smoothed out. A thirdcoat is applied and eitherwet or dry sanded as neces-sary to make the joint areacompletely smooth andready for paint.

3. Be sure that all coats of jointcompound are either set ordry before applying anothercoat of compound or paint.

FOR CRITICAL (SEVERE) LIGHTING AREA

Wall and ceiling areas abuttingwindow mullions or sky-lights, long hallways or largesurface areas flooded withartificial and/or natural light-ing are a few examples of

critical lighting areas. Strongsidelighting from windowsor surface-mounted light fix-tures may reveal even minorsurface imperfections. Lightstriking the surface oblique-ly, at a very slight angle,greatly exaggerates surfaceirregularities. If critical light-ing cannot be avoided, theeffects can be minimized byskim coating the gypsumboard surfaces, decoratingthe surface with medium toheavy textures or usingdraperies and blinds thatsoften shadows. In general,gloss, semigloss and enamelfinishes highlight surfacedefects; textures hide minorimperfections. Certain typesof paint will require the useof a primer in order to obtainbest results. Consult with thefinish paint manufacturer forspecific recommendations.

For total finishing and texturinginformation, please refer tothe “Joint Compound” and“Spray Texture” sections.

holes or knots. (These maybe cut for jack studs orblocking.) Drywall appliedover twisted studs is understress as it is hung and ismuch more likely to breakor have joint cracks.

3. Consider use of 2x4 lumberfor all bottom plates. Thiswill raise costs slightly, butwill offer much more rigidityagainst flexing along thewall length, especially nearthe axles and at the frontand rear of the house.

4. Consider building “sand-wich” beams from twopieces of 2x6 or 2x8 lumber,screwed or stapled togetherfor use as headers over double or triple windows,steel-insulated entrancedoors or sliding glass doors.At junction of this beam andall adjacent framing, use“Gang Nail” metal trussplate connectors to fasten.This will ensure adequatesupport for large openings.(See sketch below).

5. Consider use of 2x6 block-ing in wall on each side ofsteel entrance door or largewindows to add strength.(See sketch below.)

Sta-Smooth is a drywall systemoffering maximum jointstrength and easy applica-tion. It can be used in anygypsum drywall systemwhere conventional types ofgypsum wallboard are rec-ommended. This system features Sta-Smooth gypsumwallboard with a unique edge.The two edge configurationsrelieve joint deformity, damaged wallboard edges,poor alignment andextremes in humidity andtemperature.

The Sta-Smooth System pro-duces a superior jointbecause the Sta-Smoothcompound is a hardening-type compound that is notaffected by humidity once ithas hardened and dried. Italso maintains its hard coreeven with moisture addedby the use of the regularjoint compounds for the finishing work. Sta-Smoothcompound firmly bonds thetape to the board and thepanel “V” edges to eachother, making a strong,rigidized joint.

� Improved durability — TheSta-Smooth System producesa smooth, flat, durable surface that relieves beading,ridging and other jointdeformity problems.

� Greater speed — All flatjoints in the Sta-SmoothSystem are filled and tapedwith Sta-Smooth Compoundin one easy operation, thesame as conventional wall-board application methods.

� Alignment — Sta-Smoothboard, with its unique edge(either configuration), allowseasy alignment of the panelsin the same way as conven-tional tapered-edge wall-board. The taper is scientifi-cally designed to reducecrowned joints.

� Stronger bond — The bond-ing area of the Sta-Smoothjoint compound increaseswith the “V” edge panels.

� Strength — The Sta-Smoothjoint shape and the jointcompound provide greatermass and integral bond forincreased strength.





Edges: Tapered with bevel

Weight: Approximately 1.7-1.8lbs./sf

� Gold Bond Sta-Smooth components must be usedwith each other to achievefull performance benefits.

� Application, except as modified herein, shall be inaccordance with ASTM C 840.


CEILINGS

Maximum spacing of framingfor regular 1/2" gypsumwallboard ceiling surfaces tobe decorated with waterthinned spray texture shallnot exceed 16" o.c.

Foam Method: After ceilingtrusses are placed on thegypsum board, foam adhe-sive should be applied asrecommended per the manufacturer’s instructions.

To minimize foam leakage, theback of each joint may betaped with 3/4" maskingtape prior to applying foam.

Staple Method: Staples (16gauge with 1" crown and 1-1/2" legs) must be spaced4" o.c. around the perimeterof the board, either parallelor stitched, and 1/4" in fromboth ends. Screws in thefield of the board should be1-1/4" to 1-1/2" drywallscrews with maximum spacing of 12" o.c. Adjusttools properly so screws,nails and staples are drivenstraight and flush with theboard surface, withoutbreaking the face paper ofthe gypsum board.

Fire-Shield wallboard wasdeveloped to work in com-bination with other productsin an assemblies to protect abuilding from fire for certainintervals of time. Fire-Shieldwallboard is manufacturedwith a core formulated tooffer greater fire resistancethan regular wallboard.Generically, fire-resistantwallboards that are used toprevent rapid heat transferto structural members, pro-tecting them for specifiedtimes, are designated as“type X” products.

The gypsum core of Fire-Shieldwallboard works as a natural“sprinkler system.” Gypsumnaturally contains about21% water. When the boardis heated, the water in thecore begins to evaporate andis released as steam, retard-ing heat transfer. Fire-Shieldwallboard remains noncom-bustible. However, as shrink-age occurs because of theloss of water volume, cracksthat permit passage of heatand fire occur. To lessen thisprocess, Fire-Shield wallboardis formulated by adding noncombustible fibers in thegypsum to help maintain theintegrity of the core as watervolume is lost while providinggreater resistance to heattransfer.

� 5/8" Fire-Shield board isrequired for certain types ofwall and/or ceiling construc-tion, which include schoolclassrooms or units built forcommercial purposes thatrequire a timed fire rating.

� Fire-Shield can be used forceilings in HUD constructionwith 24" o.c. truss spacingwhere ceiling sag is a possi-bility. In this type applica-tion, however, 1/2" HighStrength Ceiling Board willprovide equal sag-resistantperformance at a reducedcost and with less weight.

Screwsshall be standard gypsumwallboard screws of suffi-cient length to penetrateframing a minimum of 5/8".During board application,coat all cut edges withapproved water-resistantadhesive as recommendedfor tile application. In bathor shower areas, maintain a1/4" space between thelower paper-bound edge ofthe board and the lip of thetub or shower receptor.

� Joint treatment and caulking

Using water-resistant tile adhe-sive, meeting requirementsof ANSI A136.1-1985, Type1, lay a bead of adhesive onthe tub or shower receptorflange and caulk all cornersand around all openingsprior to tile application. Spotnail and screw heads withwater-resistant tile adhesiveon surfaces to be coveredwith tile.

� Decoration beyond tiledarea

Treat all joints beyond the areato be tiled in a conventionalmanner using tape and jointcompound.

PAINTING

1. Prime all exposed MR Boardwith a high-quality latexprimer. If surface becomesmarred or is not thoroughlycovered, a second primecoat should be applied.

2. When the prime coat(s) hasdried, apply a finish coat ofhigh-quality paint such aslatex semi-gloss enamel.

WALLCOVERING

1. Prime all exposed MR Boardas in step 1 of Painting sec-tion above, using one or twocoats of primer as requiredto adequately cover the sur-face, and allow to dry. Thistreatment ensures adhesionof the wallcovering paste tothe board and facilitatessubsequent removal of wall-covering when redecorating.

2. Apply wallcovering in theconventional manner afterprimer is thoroughly dry.

� Limitations

— MR Board is not recom-mended for use where therewill be direct exposure towater or continuous high-humidity conditions such asfound in saunas, steamrooms, gang shower roomsor swimming pool enclo-sures. Cementitious tilebacker board should beconsidered.

— No vapor retarder should beplaced behind the MRBoard where tile is to beapplied to the face. A vaporretarder can be created onthe face of the MR Board by applying a skim coat oftile adhesive or by using asilicone grout for tile.

— The MR Board should notbe used on exterior ceilings.Gold Bond Soffit Board isrecommended for protectedexterior ceiling applications.

— National Gypsum recom-mends application of MRBoard to interior ceilingswhen framing does notexceed 12" o.c. for 1/2" MRBoard and 16" o.c. for 5/8"MR Board, including use asa substrate when ceramictile or similar materials areto be applied to the ceiling.

— Do not apply joint com-pound to joints or fastenersto be tiled.*

* This requirement may bewaived if the applied tile incombination with the bond-ing adhesive employed fullyprotects the gypsum boardand water-sensitive materials,if present (such as whenjoint compound is used),from penetration of water.Responsibility of performanceof completed installationsshall rest with the surfacingmaterial manufacturer and/orthe surfacing material applicator.

1/4" High Flex Wallboard issignificantly more flexible inthe vertical direction (longedges parallel to the fram-ing) than in the horizontaldirection. (See Table 1)

Wallboard joints at openingsshould be located so that noend joint will align withedges of openings unlesscontrol joints will beinstalled at these points. Endjoints should be staggered,and joints on opposite sidesof a partition should notoccur on the same stud.

1/4" High Flex Wallboard istypically installed in doublelayer construction. To preventflat spots, framing membersshould be spaced closertogether than required fortypical flat wall and ceilingsurfaces. (See Table 1). 1/4"High Flex Wallboard shouldbe held in firm contact withthe framing member whilefasteners are being driven.

For concave surfaces, a stopshall be applied to one endof the curve to restrain oneend or edge of the boardduring installation. Pressureshall be applied to the unre-

strained end or edge of thegypsum board forcing thefield of the gypsum boardinto firm contact with theframing. Gypsum boardshall be fastened by workingfrom the “stopped” end oredge. The gypsum boardshall be held tightly againstthe framing while fastenersare being driven.

For convex surfaces, one endof the gypsum board shallbe attached to the framingwith nails or screws. Thegypsum board shall be progressively pushed intocontact with the framingmembers, working from thefixed end to the free end.The gypsum board shall beheld tightly against eachframing member while fasteners are being driven.

Fasteners should be set withthe heads slightly below thesurface of the wallboard in adimple formed by the ham-mer or power screwdriver.Care should be taken toavoid breaking the facepaper of the wallboard.Improperly driven nails orscrews should be removed.

One of the problems involvedin handling gypsum wallboardinvolves proper size andplacement of supports instorage. This is particularlyimportant in instances wherewarehouse handling ismechanized and the majorityof the board is transported byforklift. The Gypsum Associ-ation Materials HandlingCommittee recommends thefollowing procedures for correct storage and handling.

Diagram No. 1 shows the correct method of placingsupports when wallboard is tiered several units high. If risers are not placedaccording to the diagram,the cumulative pressure onlower units can cause sag,as the diagram shows.

Diagram No. 2 shows the recommended number ofsupports for various lengthsof board, regardless of thick-ness. With slow-movingitems that require prolongedstorage, the problems ofwavy-edged boards can besolved by reducing the spanbetween risers to 28" or less.Materials used for supportsshould be 4" in width. Takegreat care in placing the risers and, as the units aretiered, align the risers frombottom to top so that eachtier rests on solid bearing.

Dry storage is essential andweather protection shouldbe provided for all gypsumproducts in storage.

TIPS FOR STORAGE,HANDLING AND USE

1. Storing panels indoors isdesired. Keep them cleanand dry.

2. Rotate stock — first in, firstout. Rotate all gypsumboards at least every sixmonths.

3. During periods of coldweather, bring the next day’smaterial inside to warm upbefore use.

4. Regularly check pallets (ifused) for damage and loosenails or screws. Repair andresurface as needed.

5. When putting units ofboards on pallets, pull forksstraight out — slowly andgently — as unit is loweredto surface of pallet. Do notdrop! Use fork extenders.(See Diagram No. 3)

6. When stacking loaded pallets,set them flat on the oneunderneath and keep themin vertical alignment witheach other to avoid damage.Maximum height should beno more than four loadedpallets.

7. Keep ceiling jig clean and ingood repair. Re-level and/orresurface as needed.

8. When laying out ceilingboards, do not drop oneboard over another. This cancause a core fracture in thedropped board. In addition,do not drop boards onto the ceiling jig; this also canfracture the board core.

9. Do not drag Seaspray Hi-Strength MVR panels facedown over the ceiling jig,because this may damagethe surface. Also avoid thiswith regular ceiling boardbecause the face of the boardmay be damaged.

10. When pulling a panel off aunit to lay out on the jig, donot drop the board on itsedge. Instead, set it downcarefully. Dropping theboard on its edge will crushthe core and can break thepaper.

11. Avoid walking on ceilingboard and do not throwrafters or lumber on theback side. This can breakthe gypsum core.

12. Clean any leakage of foamadhesive from the face ofthe panels, to avoid damageto the paint finish or facepaper.

13. If it is necessary to cut orrip a Seaspray Hi-StrengthMVR panel, cut from faceside and snap. Then cutback paper. This will mini-mize damage to the paintcoat on the face.

14. For best results, SeasprayMVR paint should be keptfresh. Keep cans closedtightly. Before using, shakecan thoroughly and stir tomix pigment, which mayhave settled.

Sta-Smooth HS is a high-strength,quick-setting compounddeveloped by NationalGypsum specifically for themanufactured housingindustry. Designed primarilyfor ceilings, Sta-Smooth HS minimizes the costlycracking that often occurswhen ceiling panels aremoved for assembly.

Unlike other compounds, Sta-Smooth HS develops its highstrength within the first hourof application, minimizingthe potential for cracks andfractures. Sta-Smooth’squick-setting formula alsopromotes quality and effi-ciency on the productionfloor. One coat of Sta-SmoothHS Compound is normallyall that is required when the surface is to be spray-textured.

ProForm® BRAND spray texturescan be sprayed on the treatedjoint the moment the com-pound is hard, but not dry.Spraying can begin from thetime the compound is set.

For best results, Sta-Smooth HSmust be used in combinationwith reinforcing tapes suchas Sta-Smooth HS Tape orProForm Paper Joint Tape.For unsprayed ceilings, Sta-Smooth Lite is recom-mended as a second coatprior to stomp/knockdownor smooth finish.

Spray textures on ceilings create a monolithic lookwhile concealing minor surface imperfections andirregularities.

� Sta-Smooth HS JointCompound develops its high strength in less thanone hour, minimizing thepotential for cracking.

� Available in five working-settimes to meet industry needs.

� Packaged in easy-to-carry25-lb. (11.3 kg) bags.

� When a spray texture isspecified for ceilings, theusual second coat of com-pound can be eliminated,saving time and labor.

� Noncombustible.

When mixing the compoundwith water, use only clean,drinkable water. Use of dirtywater or other materialscould result in inconsistentset times and possibly nobond to the wallboard.Clean mixing equipmentand tools thoroughlybetween batches. Materialshould not be overmixed;this will result in shortenedworking times.

Sta-Smooth HS should not beused over another productuntil the first coat is set hardto the touch.

Each coat of Sta-Smooth HSmust be set hard to the touchbefore adding a second coator a vapor barrier spray.

Apply Sta-Smooth HS JointCompound at a heavy consistency, making sure tocompletely fill the wallboardjoint through the tape. Foroptimum results, use Sta-Smooth HS Tape orProForm Paper Joint Tape.

As soon as Sta-Smooth HS startsto harden, shave off all trowel,knife or joint marks or excesscompound using a 6" finishingknife. Do not wait to smoothout marks and protrusions or the compound will beextremely difficult to sand.

If the surface will not be textured,apply a second, wider coat of Sta-Smooth Lite JointCompound. Sta-Smooth Lite is a lightweight setting compound that produces asmooth, easy-to-sand finish.

Once a second coat has beenapplied, feather all edges andfinish the surface smooth andlevel. The wet sponge sand-ing method offers excellentresults, avoids creating dustand can be started as soon asthe compound has hardened.

When ProForm spray textureswill be applied, the secondcoat of compound can be eliminated. This savesvaluable time and labor inassembly-line operations.

Sta-Smooth HS can be decorat-ed with either a good-qualitywall or ceiling paint or aspray texture. Apply paintafter priming according tothe recommendations of thepaint manufacturer. ProFormspray texture products canbe used as directed afterpriming with an alkyd flatpaint or a vapor barrier seal.

CONDITIONS

GYPSUM BOARD PROBLEMS

Wavy board

Uneven joints(See “High joint” for finishing)

Foam adhesive leakagebetween gypsum boards

Wet board

Gypsum core fracture

Cracks in field of board created during ceilingmovement in plant

PROBABLE CAUSE

Improper storage/slow stockrotation (less than 3 months)

Debris on the ceiling jig.Unlevel ceiling jig. Wavyboard.

Warped rafters, or rafters withexcess camber. Unlevel orunclean ceiling jig.

Poor storage area that is notprotected from weather.

Rough handling. Droppedboard on its edge, or drop-ping one board acrossanother.

Ceiling hoists not picking uptops uniformly. Inadequatesupport of top. Excess flex-ing due to lightweight sideor edge rail. Inadequate orincorrectly positioned spliceblocks.

PREVENTIVE ACTION

Be sure gypsum is storedindoors, and kept dry. Risersmust be spaced properly,and be vertically aligned.

Keep ceiling jig clean and freeof debris. Re-level andresurface as needed.

Apply 3/4" masking tape overjoints on back side of boardprior to laying rafters on them.“Stitch stapling” of joints onback side helps to keep boardsin position while rafters arepositioned. Check rafters regu-larly – bottom chords shouldbe flat and straight, with theleast camber possible.

Store gypsum board in covered,dry area.

Do not allow board to bedropped on ceiling jig. Layout panels with care. Avoidwalking on back of boardwhile on ceiling jig unlessjig has a solid, flat surface.

Provide an adequate number ofpick-up points in the hoist.Synchronize hoist motors. Use2"x3" or 2"x4" instead of 1"x3"or 1"x4" for side or edge rail.Splice blocks should not bepositioned at the same placeon opposite sides of the top, orat the transition areas betweenvaulted and flat ceilings.

CORRECTIVE ACTION

If using foam adhesive applica-tion, store the gypsum on aflat surface, possibly on longlength wood pallets. Keep onthis surface for several daysprior to using. If a mechanicalattachment is used, simplydecrease fastener spacing to“pull” gypsum to rafters, there-by flattening gypsum board.

Store board properly. Tape jointson the back side to minimizefoam adhesive leakingthrough to the ceiling jig.

Clean leakage off front of board,taking extra care not to damage paint/texture finishwhen using Seaspray MVR.

Gypsum board may be used if itis only damp, and is allowedto dry completely. If boardexhibits any of the followingqualities, do not use it: boardis wet with stains on face;mildew is present; gypsumcore is separating from paper.

Cracks less than 12" in length canbe finished with joint com-pound. Small Seaspray Hi-Strength MVR cracks can befilled with DAP tub and tilecaulk and covered with touch-up paint. Cracks greater than12" in board should result inboard replacement.

Small cracks (less than 12" inlength) can be finished withjoint compound. SmallSeaspray Hi-Strength MVRcracks can be filled withDAP tub and tile caulk andcovered with touch-uppaint. Large cracks (greaterthan 12") in board shouldresult in board replacement.

PROBABLE CAUSE

Manufacturing defect.

Rough handling of board.Dragging face of SeasprayHi-Strength MVR acrossceiling jig.

Old touch-up inventory. Paintis not properly mixed.

Failure to prime prior to texturingallowing board to absorbexcess moisture. Excess insula-tion weight. Condensation inroof cavity.

The addition of excessive waterto blown-in cellulose insula-tion.

Slow drying of finishing coats.Too much compound undertape. Joint compound toothin. Overthickness of edgesof tape. Tape too absorbent.

Compound applied too thin inviscosity and thickness. Toolittle compound over joint.Excessive sanding.

Excess joint compound underor over the tape andimproper feathering. Poorframing. Improper wall-board application. Impropersanding. Use of compoundtoo heavy.

Lumber expansion and contrac-tion. Improper heating andventilation. Cold weatherwith high humidity. Improperapplication of wallboard.Excess compound over jointsand needless wide joints.Delayed shrinkage. Rough orpoorly cut butt joint.

PREVENTIVE ACTION

Immediately notify NationalGypsum, or its distributor. Itwill be necessary to com-municate the manufacturingcode (on the back of theboard), and save a sampleshowing the problem.

Handle board carefully whenlaying out on ceiling jig.

Turn inventory – if paint isolder than 3 months, itshould not be sold. Prior touse, shake and stir paintthoroughly to mix pigment.

Prime ceiling prior to texturing.Use a HUD-approved vaporbarrier. Support insulationweight independent of gyp-sum. Use framing 16" o.c.,or 1/2" High StrengthCeiling Board where 24"o.c. rafter spacing is desired.

Care must be taken to followthe insulation manufacturer’sspecifications on addition of water.

Correct drying conditions.Embed tape properly. Usejoint compound thicker. UseProForm Joint Tape.

Use finishing compound atheavier viscosity and properthickness of coats. Do notoversand.

Proper thickness of compoundsfor taping and finishing. Featherfinishing coats wider than pre-vious coats. Correct poor fram-ing and improper wallboardapplication to ensure properalignment. Sand properly.

Use Sta-Smooth System to minimize beading or ridging.Alternatives include double-layer lamination system.

CORRECTIVE ACTION

If ceiling is already up, usetouch-up paint on all spots. Ifareas requiring touch-up areexcessive, it may be necessaryto paint entire ceiling. If prob-lem is noticed prior to layingboard on jig, do not use.

Use Seaspray MVR touch-uppaint on affected areas.

Mix paint thoroughly. If it doesnot match, contact local dis-tributor or National Gypsumimmediately for fresh paint.

Replace ceiling board andemploy preventive actions.

Replace ceiling board andemploy preventive actions.

Sand down the tape outline andseal. Refloat if necessary beforedecoration. Prevent finish coatmoisture from rewetting thetape by applying a thinnercoat for fast drying.

Allow to dry thoroughly, thenapply an additional coat oftopping or joint compound.

Sand joint to near flush withoutsanding into tape. Apply awider finishing coat proper-ly feathered, if necessary.Apply a second finishingcoat or skim coat.

Allow one full heating cycle —six months to one year —before repairing. Sand ridgeflush and apply one or morefinishing coats of joint ortopping compound. Usecritical lighting to determineif bead is eliminated prior todecoration.

Too little joint compound undertape. Joint compound too drybefore embedding tape.Improper bedding of tapeinto joint compound. Loss ofbond (see bond failure). Endply separation. Rupturedwallboard ends or edges.Joints too wide and unfilled.

Usually caused by rupturedboard or a manufacturingflaw.

Adverse drying conditions.High temperatures and low humidity and drafts, orlow temperatures and highhumidity. Joint compoundapplied in excessive thickness.

Joint too wide or not filled.Improper drying betweencoats. Excess thickness ofcompound over tape at apexof corner. Extremely fast orslow drying conditions.Applying compound to bothsides of inside corner atsame time.

PREVENTIVE ACTION

Provide heat and ventilation todry framing lumber. Alignframing lumber. Nail centerof wallboard first. Holdwallboard firm to nailingmember when nailing. Useproper nails. Systems rec-ommended to reduce oreliminate nail pops includedouble-layer lamination,double nailing system, float-ing angle system, adhesivenail-on system and screwapplication.

Align framing lumber. Allow drylumber to become acclimated.Correct wallboard applicationas described for nail pops. Useproper nail spacing. When fur-ring, use no less than 2" x 2".Use systems recommended toreduce or eliminate nail pops.Avoid fracturing paper whendriving nails.

Follow joint compound mixingand application instruction.Embed tape properly intoample joint compound. Cutout any ruptured ends oredges of wallboard and fill allwide holes and joints withSta-Smooth HS prior to taping(see end ply separation).

Check field of board prior todecoration for imperfec-tions. Make any necessaryrepairs.

Fill all wide wallboard jointswith Sta-Smooth HS. Correctdrying conditions. Applyjoint or topping compoundless thickly, but use morecoats. Allow thorough dry-ing between coats.

Fill wide joints with Sta-SmoothHS prior to taping. Embedtape properly and allow todry. Apply compound to oneside and allow to dry, thentreat other side.

CORRECTIVE ACTION

When nail pops occur beforedecoration, repair immediate-ly. If problem occurs after decoration, repair after framinglumber is dry (usually oneheating cycle). To repair, drivea 1-1/4" drywall nail 1-1/2"from each side of popped nailwhile holding wallboard firmto the nailing member.Countersink popped nail,remove loose joint compound,then apply finishing coats ofjoint or topping compound.

Repair as described for nailpops, unless most nails aredepressed and wallboard isloose (usually ceilings).Renail entire surface usingproper spacing. Dimpledepressed nails and applyfinishing coats of joint ortopping compound.

Repair tape blisters by slittingand filling with joint com-pound and smooth out withfinishing knife. Cut out otherloose areas, fill with jointcompound when necessary.Let dry, then retape and finish.

Before decoration, cut outloose area and fill flush withjoint compound, if deep.Tape and finish. After deco-ration, use a PVA glue to fillblister adequately to ensuregood bond. Roll smoothwith small, dry paint roller.

Additional coats of joint or top-ping compound will fill thecracks without reoccurrence.

Fill wide cracks with joint ortopping compound. Forhairline cracks, run a point-ed object (10D or 16D nail)along the apex of cornerwith adequate pressure toclose crack.

Note: During October 1994,HUD revised the “Heatingand Ventilation” section3280.504 so that the omis-sion of the ceiling vaporretarder in climate Zone 1is permitted if certain otherventilation requirements aremet. In climate Zones 2 and3, a vapor retarder will stillbe required in all ceilings.

Ceiling board which is tobe textured in plant mustbe primed with a sealing drywall primer to improvetexture “hide” and preventdiscoloration problems.Primer must be drybefore texture is applied.

The intent of these recommen-dations is to ensure anacceptable ceiling appear-ance. Most of climateZone1is a high-humidityarea. Humidity and certaintemperature conditions canresult in excess moisturebuild-up in roof cavitieswhich can lead to severeceiling panel problems.Continued use of a vaporretarder will help controlpotential moisture problems.

Additional Ventilation and Moisture Control

To ensure maximum performance of all components in a home, adequate ventilation through theroof cavity is essential. Whether the method of ventilating the cavity is by passive means orpowered vents, we would suggest as a minimum the following construction tips:

• If the house has a soffit overhang, some positive means to stop blown-in insulation at the heel ofthe roof truss must be used. Air flow is at best limited through the typical lower pitch roof and theperforated soffit area must be clear and unobstructed.

• If power roof vents are used, they should be of good quality and thermostatically controlled. Besure that vents used are capable of moving enough air for the space involved.

• If a passive system is used, vents should be spaced evenly over the roof area, and should besufficient size. These vents should be in both halves of multi-section models and as high up aspossible for maximum convection to occur.

• Consider building ridge beams with openings cut through both, to allow for cross flow of airbetween halves of the house.

• Another good way to achieve additional flow of air through a roof cavity is by using gable vents onboth halves of the house.

• Proper site preparation before the house is set is critical. The site should be graded to ensurethat water flows away from the house in all directions.

• Whether the house is skirted or to be set on a permanent foundation, adequate ventilation hereis also critical, to minimize moisture build-up under the home.

• Before setting the house, we would also suggest placing a plastic ground cover underneath, to coverthe entire under house area.

Moisture build-up over a period of time can cause ceiling sag or discoloration, cracking of fin-ished joints in the gypsum board and even mold or mildew. These problems may be greatlyminimized by ensuring an adequate flow of air, both under the house and in the roof cavity.

CONDITIONS

MISCELLANEOUS PROBLEMS

Putrefaction

Pock marking

Let down

PROBABLE CAUSE

Compounds mixed with conta-minated water, dirty mixeror pails. Mixed compoundsallowed to stand for pro-longed period of time. Hotweather.

Entrapment of air in the mixedcompound and in applica-tion. Overmixing of com-pound. Compound mixedtoo thinly. Heavy fills.Improper application tech-nique. Compound appliedtoo loosely.

Too much water used in initialmix of dry powder com-pound. Extremely coldwater and/or compound.

PREVENTIVE ACTION

Use clean water and clean mix-ing equipment. Avoid waterused for soaking and clean-ing tools. Avoid exposure ofbagged compound to sun forextended periods.

Mix compound as quickly as pos-sible and let stand until binderis in solution before remixing.Mechanical mixers shouldhave 500 RPM maximum. Useheavier mix. Make additionalpasses over joints and beadwith hand or mechanical tools.File trowel edges square regu-larly to avoid entrapment inapplication. Apply compoundthinly and use more pressureon finish coat.

Use no more water than direct-ed for mixing. Store com-pound in heated area in win-ter. Use water with tempera-ture above 60°F. Mix pow-der in water to very heavyconsistency. Allow to stand(winter, 30 minutes; summer,15-20 minutes), then remix.

CORRECTIVE ACTION

Do not use compounds thathave started to putrefy.

Remove sanding dust that maycollect in “pocks” prior topainting and refloat joint asnecessary. When conditionexists after painting, floatwith compound and repaint.

Add additional powder andmix to a heavier consistencythan required. Allow tostand (winter, 30 minutes;summer, 15-20 minutes),then remix.
