For further information on Personal Protective Equipment, visit yachtpaint.com

Providing health and safety precautions for paintproducts is a legal requirement and forms a specificsection on our labels. However, the wording is laiddown by law and is often difficult to understand.This section is intended to help you interpret andunderstand the symbols and phrases you will find inour literature and on our product labels. Weve alsoincluded some further information to make applyingpaint a safer job.

Before starting work always read the label. Each can may display a number of warning symbols andwritten warning phrases which will quickly indicatethose areas where particular care should be taken.Other general safety precautions are detailed belowand will help should any problem occur while usingour paints.

Personal Health

Avoid ingestionFood and drink should not be prepared or consumedin areas where paint is stored or is being used. Incases of accidental paint ingestion seek immediatemedical attention. Keep the patient at rest, do NOTinduce vomiting.

Avoid inhalationThe inhalation of solvent vapor from paint, or dust from sanding, can be reduced by the provisionof adequate ventilation or extraction. If this is notsufficient, or if specifically stated on the label,suitable respiratory protection should be used. Wear a cartridge type respirator when abrading oldantifoulings never burn off or dry-sand antifoulingsas this may create harmful fumes or dust.

In badly ventilated areas wear an air-fed hood or cartridge respirator with an organic vapor filter. Solvent fumes are heavier than air. Breathingthese fumes can make you dizzy, feel drunk andheadachy and could even result in collapse. Read the label carefully and ensure that therecommended protection is worn.

Spray painting creates additional health hazards.Spray mists should not, under any circumstances, be inhaled. Read the label carefully and ensurerecommended protection is worn; generally an air-fed hood is the best protection as it provides a fresh air feed to the user.

Boat Paint Guide

Avoid eye contactEye protection should be used during paintapplication and when there is any risk of paintsplashing on the face. Safety glasses or goggles areinexpensive, available from many DIY stores, andare well worth wearing. Use eyewear that complieswith ANSIZ871-1989 Standard. If material doescontaminate the eye, it is recommended that theeye is flushed with clean fresh water for at least 15 minutes, holding the eyelids apart, and medicalattention sought.

Avoid skin contactSkin irritation can occur from contact with paintproducts. You should, therefore, always wearprotective gloves and protective clothing whenapplying or mixing any paint products. Overalls,which cover the body, arms and legs, should beworn. Skin cream, of a non-greasy barrier type, maybe used on the face. Do NOT use petroleum jelly asthis can help the absorption of paint into the body.Remove rings and watch straps before commencingwork, as these can trap paint particles next to theskin. Remove any paint that does get onto the skin by washing with warm water and soap or an approved skin cleanser. After washing, apply a skin conditioner. Never use solvent or thinners to clean the skin.

Risk of fire or explosion

Most paints contain organic solvents some of whichevaporate into the air upon opening the container. Any dangers can be reduced if a few simpleprecautions are taken:n Avoid open flames where paint is being stored,opened or applied

n Do not smoke

n Store paint in a well-ventilated, dry place awayfrom sources of heat and direct sunlight

n Keep the can tightly closed

n Avoid sparks from metals, electrical appliances beingswitched on and off, or faulty electrical connections

n Do not leave paint soaked rags lying around,in the pockets of overalls or in waste bins. Sometypes of paint can dry out and auto-ignite.

Key points to note when applyingfinishes and varnishes:

n Dry, well ventilated conditions are preferablewhen applying finishes or varnishes. While gentleair movement will assist the drying process, a dust-free environment is critical to achieving a good quality gloss finish; always avoid painting in windy conditions.

n The effects of dust contamination may be furtherreduced by sanding lightly between each coat,removing residual dust by wiping down with asuitable solvent and allowing to dry beforeapplying the next coat. This will also help improvethe initial aesthetics.

n Avoid applying two-part finishes or varnishes late in the afternoon or when relative humidityexceeds 80% as these products are particularlysensitive to moisture. Condensation duringapplication or due to overnight ambienttemperature changes can affect the chemical cure of these products resulting in loss of gloss.

n When painting orvarnishing wood avoidapplying if theambient temperatureis increasing (orpredicted to increase)significantly.

Choosing a faster drying product or system, where available, will help to minimize the windowfor dust contamination.

This is because rising temperatures cause woodto expand, which can lead to blisters forming inthe paint or varnish film. A good tip is to applywhen the temperature is falling, as the wood willbetter absorb the paint or varnish, giving betteroverall results.

Key points to note when applying epoxies (e.g. Watertite, InterProtect,Epoxy Primekote)

n When curing in high humidity conditions,particularly at lower temperatures, epoxies candevelop an amine blush on the surface. Thisslightly sticky substance must be removed andcan normally be washed off with soap and water.If the blush is notremoved it can leadto the delaminationof subsequentcoats. Failure toremove the blushwill also makesanding moredifficult.

n High humidity conditions can reduce the amountof solvent evaporation during the drying/curingstages; with epoxies this can lead to a softcure. As epoxy-based materials are generallyapplied at a higher film thickness, solvent canremain trapped in the film for many days leadingto slow or poor final cure.

n Although epoxies generally cure well in mostconditions, when the temperature falls to 45F or below, curing can slow or even stop.Remember to check both day and overnighttemperatures whether working outdoors or in a shed.

n Epoxy products usually respond well to a littleheat; on cold days introducing a safe form ofheating into the application area is well worthconsidering.

n Always check the weather!When painting outside, always check what weather conditions are anticipated duringthe preparation, application and drying phases of any project. Should fair weatherprevail, whether or not to commence painting will then depend on the air and surfacetemperatures, humidity and dew point.

You may find the following hints and tips helpful when planning your project further,product-specific guidelines can be found on individual product labels and data sheets.

General Guidance Notes:

n Dew point is important when applying paint to a surface, as the evaporation of the solvent fromthe paint draws heat and/or energy from thatsurface, cooling it down. If conditions are rightcondensation may form on the surface of thepaint resulting in various problems.

n Relative humidity is important as air can onlyhold so much water or solvent vapor at any onetime. So, as the relative humidity increases, thelevel of solvent vapor the air can hold reduces,meaning paint will effectively dry more slowly.

n Air and substrate temperature will affect thedrying properties of any paint. Failing to observethe recommended drying times can result incoating failure, including improper drying,wrinkling and loss of adhesion.

n Always avoid extreme air or temperatureconditions; Interlux products are tested across a range of temperatures, to ascertain the drying times and application characteristicsof each product. Drying time recommendationsare provided on our products labels; furtherinformation relating to weather considerationscan be found on our product data sheets,available on our web site.

n Low temperatures will increase drying times;always check the through-dry of each interimcoat, before sanding or overcoating.

n Sanding too early can cause the paint to wrinkle under the sand paper, in some caseseven tearing or gouging into the paint filmmaking refurbishment difficult. Sanding beforethe paint film is through-dry can also clog thesand paper, meaning more sheets are needed to complete the task.

n Overcoating too early can cause wrinkling,blistering and loss of gloss in the finished paint job.

n High temperatures will reduce drying times, but can make application more difficult, asproduct flow and leveling can be compromised particularly when applying finishes or varnishes.Where appropriate, thinning recommendations to help with higher temperature application areprovided on labels and data sheet.

n Do not paint in direct sunlight, or when thesubstrate itself is excessively warm, as theresidual heat of the substrate can adverselyaffect the application and drying properties ofany paint product; this can result in poor flowand leveling, rapid drying, cracking and loss ofgloss. Surface temperature can be measuredusing a surface thermometer.

When applying two-part products in highertemperatures the pot life of the product will also be affected, reducing your work time window.

Remember that surfaces heat up and cool down ata different rate to the surrounding air temperature,meaning even though the ambient temperaturemight seem warm, the temperature of the surfacebeing worked on may still be quite cold. Very oftenone side of a boat will be in the shade and theother in bright sunlight meaning the applicationconditions will differ. Additionally, in the morningthe surface temperature of the sunny side willgenerally be lower than the ambient temperature,whereas in the afternoon it may be higher.

InspectionInspect for damage. Small repairs can be tackled easily, but any damageaffecting a large area, or affecting the structure or hull integrity, should bereferred to a professional for proper assessment.

Preparation and PrimingRemove any loose filler or gelcoat and abradeedges to remove loose material. Remove alldebris and prime with InterProtect 2000E or Epoxy Primekote, according to systemrecommendations provided elsewhere in this guide. Apply Watertite or Interfill after the first coat of primer.

n Making small repairs to fiberglass surfaces

When working with fillers its important to remember that epoxy fillers arerecommended for both above and below the water areas; polyester fillers are suitable for use above the water only. Interlux Watertite is a two-part epoxy filler, suited to most DIY repairs above and below water.

Applying the fillerMask off the damaged area and apply Watertiteusing a putty knife or spatula. Allow to cure,following the recommendations provided onthe product label.

Once cured, sand with 80-220 grit paper. The finished repair should be smooth and levelwith the surface. If required a second layer offiller may be applied, repeating the sameprocess. The repaired area can then be primed, ready for painting.

n Two-part epoxy fillers are the most widely used fillers in the yachting industry. They are invariably solventfree. A benefit of being solvent free is that they do not attack the underlying primer.

n Epoxies must be mixed in the proper ratio. Too much curing agent and they will leave a sticky film on thesurface that is not suitable for overcoating. Too little curing agent will weaken the filler and cause it tocrumble later on.

n Below the waterline, epoxy fillers must be used. Polyester fillers should not be used as they have agreater propensity to absorb water.

PreparationHigh pressure fresh water wash, to removeloose antifouling; ensuring all residue andwash water is contained and disposed of,according to local legislation. Mask off areas to be stripped.

Applying InterstripApply Interstrip 299E liberally, using an oldbrush, following the application guidelinesprovided on the product label.

Leave on the surface. The product needs time to work; the time needed willvary depending on the temperature and the amount of old antifouling on thehull.

For best results, work on a small area at a time do not allow the product to dry out.See product label for more information.

n We do not recommend using a chemical paint stripper when working with fiberglass, unless the producthas been specifically approved for this purpose, as this may cause damage to the substrate.

n Varnishing is best achieved on warm, dry mornings cold weather slows drying and dampness spoils the gloss.

n When working with wood, always work in the direction of the grain, whether sanding or applying varnish.This will avoid scratches that can still show through, even after many coats of paint or varnish.

For health and safety reasons, two-part polyurethane products should only be spray applied by a professional applicator.

Preparation in poor conditionIf previous finish is cracking, peeling or showing signs of separation from the substrate all previouscoatings should be removed and the substrate primed.

See Page 21 for advice on removing existing finishes.

There are three easy choices:

1. Check for compatibility with old antifouling. If the product is known use the Interlux Compatibility Charton Page 43 of this manual.

2. If the old antifouling is unknown you can apply Primocon primer directly. Then simply overcoat with the Interlux Antifouling of choice (do not use this system with VC17m Extra, VC17m, VC Offshore or Baltoplate).

3. Remove the old antifouling. If the old antifouling is in poor condition remove it using Interlux Interstrip299E. After stripping you are ready to prime and paint.

InspectionCheck for areas of damage, separation or peeling, or any other indicationsthat the existing coating is not firmly adhered to the substrate.

Previously painted surfaces:

Preparation in good conditionRemove surface contamination by wiping down with Interlux Special Thinner 216 orFiberglass Surface Prep YMA601. Once thesurface is clean abrade with 220-320-gritsandpaper. Remove the sanding residue andallow to dry.

Using a two-part finish? Ensure your existing coating is compatible.

4 MaskingBefore priming/undercoating, mask off the area to be painted.

5 Priming/UndercoatingTo obtain the finest finish on fiberglass andwood and in the case of metal substrates thesurface will need to be primed. Your choice of primer and undercoater will be dictated by substrate and choice of finish coat. Systems for applying topside finishes begin on Page 60.For further advice contact Interlux at 1-800-468-7589.

Bare substrate:

As gelcoat ages it becomes porous and brittle which may lead to cracking and blistering. To seal the gelcoat and get a finer finish apply InterProtect 2000E or Epoxy Primekote.

Apply the finish, according to labelrecommendations.

n Ensure an even spread by holding the brush at 45 this minimizes brush marks.

n The best finish is achieved on large areas by two people, one to apply the paint, the other followingimmediately behind to tip off the finish.

n Clean or change brushes every 20 minutes or so. Always use lint-free cleaning cloths.

n Stir the can occasionally during the work.

n Dampen the ground with water before commencing painting to avoid any dust rising.

n Use a worn brush for the final coat, this will ensure less brush marks.

n Painting is best achieved on warm, dry mornings cold weather retards drying and damp will spoil thegloss.

n Never apply direct from the can as this will introduce contamination.

n Always pour the amount of paint that you expect to use into a separate container.

n Applying varnishesTo achieve a professional result from any varnish project, thorough preparation iscritical. If applying on to a previously varnished surface, the condition of the existingcoating and its compatibility with the new varnish product should thoroughly checkedbefore commencing any preparatory or application work.

Using a two-part varnish? Ensure your existing coating is compatible.

Wipe down thoroughly with Special Thinner 216or Brushing Liquid 333 and allow to dry completely, to ensure any residual sanding dust is removed.

Preparation in poor conditionIf previous varnish is cracking, peeling or showing signs of separation from the substrate this should be totally removed.

Continue at Step 5.

See Page 21 for advice on removing existing varnishes.

It is important to ensure all sanding residue is removed prior to varnishing, as this will impair adhesion and give abitty finish. Before commencing any varnish work, decant the amount of varnish you expect to use into a separatecontainer, to avoid introducing contamination into the tin.

Bare wood:

PrimingWe recommend that the first coat of varnishapplied is thinned up to 15%-20%. This willpromote good penetration of the surface, andadhesion of subsequent coats. After the firstcoat has been applied, the surface will appearrough. This is a result of the exposed ends ofgrain absorbing the varnish and lifting. Sandsmooth with a 220 grit sandpaper and apply a second coat thinned 10%-15%.

Apply 2-3 thinned coats of varnish followinglabel recommendations.

Alternatively, prime using Clear Wood SealerFast Dry; a clear polyurethane primer withexcellent grain filling properties that willimprove overall scheme durability andaesthetics.

6 ApplicationApplying varnish with a brush is usually thebest method, although roller application can be effective on large, flat surfaces.

Brush out, using firm strokes along and thenacross the grain, holding the brush at 90 to the surface.

Finally, tip off by gently stroking surface withthe brush at a 45 angle, following the grain.The brush you use should be used only forvarnishing.

Hints and tips

n Keep the sandpaper clean and change it frequently.

n Sand by numbers, finishing the surface with aprogressively finer grit of paper.

n Varnishing is best achieved on warm, dry mornings cold weather slows drying and damp spoils the gloss.

n Always use a clean brush, previously used only forvarnish.

n Always buy the highest quality varnish and brushavailable. This will ensure you achieve the mostattractive finish.

n Clean new brushes before use.

n Test the finish on a spare piece of wood beforeapplying to the boat.

n On large areas use a foam roller to apply the initial coat,followed immediately behind with a wide brush for thefinishing strokes this is best done by two people.

n After cleaning with the correct thinners, wash thebrush in detergent and warm water, dry and wrap in greaseproof paper in a fine chisel shape.

n Alternatively, having cleaned and washed the brush,suspend by its handle to avoid any fishtailing of thebristle.

n As the varnish ages in the can you may find there are lumps or contamination. Filtering the varnish into a separate container through cheesecloth, a paint filter or an old stocking is a good solution to thisproblem.

n Dont use varnish which has been open for a longperiod as it will have picked up dust.

n Do not varnish wood when exposed to direct sunlight.

n Never leave bare wood exposed too long as it willabsorb moisture from the atmosphere.

Boat Paint Guide




Always follow the system recommendations as specified on the label; this will indicate the minimumnumber of coats required and the sanding recommendations between coats. This information will varydepending on the product. To achieve long-lasting protection, you should plan to apply up to ten coats(depending on the system). As the number of coats increases, sanding between coats with a fine grit paperwill increase the level of gloss and depth of luster.

n Applying antifoulingAntifouling can be applied using a brush or roller. Using a small roller is less work onthe arm but takes longer to cover the surface area. If a brush is preferred, choose alarge width brush; the finish will not be as smooth as a topside paint so the type ofbrush used is not critical.

Boat Paint Guide



Apply an extra coat to leading and trailingedges; e.g. waterline, trim tabs, outdrives, keels and rudders. These areas experiencemore water turbulence and so more wear on the paint surface.

Follow overcoating times and immersion times carefully. Failure to do this could result in detachment, blistering or cracking of the antifouling. The marine environment is harsh for paint so it must be allowed to dry thoroughly before immersion.

6 ApplicationMix paint thoroughly with a stirring stick,ensuring that any settlement is mixed in. Apply according to label recommendations,using a brush or roller.

Apply the antifouling at the correct thickness; this may mean an extra coat is needed, depending on application methods and conditions.

n Painting outdrives, stern gear, propellers & keels

Outdrives and stern gear are usually constructed from aluminum. Propellers are usually bronze or aluminum. Keels are typically cast iron or lead. Its important tochoose an antifouling that is hard, durable and suitable for these high wear areas and also one that is compatible with the substrate you are painting.

Tim TaylorTechnical Service Representative

Once youve confirmed your substrate see Page 17 for substrate preparation information and follow this advice carefully.

2 PreparationThe key to protecting your underwater metals from corrosion is correctpreparation of the substrate and choosing the best priming solution for your project. Before commencing any preparation, it is important to establishthe type of metal you are working with.

Boat Paint Guide




See Pages 44-47 for primer recommendations.

PrimingApply a primer recommended for the selectedantifouling and substrate; always follow the recommendations given on the productlabel.

3

4 Applying antifoulingApply the selected antifouling, following thelabel recommendations on film thickness,overcoating and immersions times carefully.

Not all antifoulings are suitable for application to bronze and aluminum, so its important to check compatibilitywhen selecting which antifouling product to use. See Pages 04-07 for antifouling product information.

Care should be taken not to paint zinc anodes, which are often located next to the prop shafts, as this will seriously reduce their effectiveness. When painting your outdrives, underwater metals and keels, the longevity of any antifouling is difficult to predict as coating adhesion can be an issue, particularly onpropellers. Thorough surface preparation is critical to promote good adhesion between the substrate and the coating.

1. Check for compatibility with old antifouling.If you know what antifouling is currently on yourboat, you can quickly determine whether yourInterlux paint choice is compatible.

2. Use Primocon YPA984 as a tie-coat primer.If you do not know what the old antifouling is on your boat, it is still easy. Apply our PrimoconYPA984 primer directly to the old antifouling. Then simply overcoat with the Interlux antifoulingof your choice. (Not compatible with VC

Offshore, Baltoplate, VC17m, VC17m Extra or any water based paints.)

Applying your desired Interlux antifouling has never been easier. Compatibility is always an issue boaters must worryabout, but there are 3 easy steps to solve this problem:

3. Remove old antifouling. If you would prefer to remove the old antifouling, we have the easysolution, Interlux Interstrip 299E paint remover. Its compatible with your valuable fiberglass hull.Interstrip can remove several coats of paint in oneapplication. After stripping, you are ready to primeand paint your newly cleaned hull.

n How much antifouling paint do I need?Determining how much antifouling you will need is fairly simple. Here are two quick guides to help you purchasethe correct amount:

1. Calculate the area needing paint. For a rough estimate of the area to be painted, multiply the length of your hull(LOA) by the beam and multiply by 0.85 (LOA x B x 0.85 = Area). Then divide the area by the coverage of thepaint youve chosen to determine how many quarts per coat you will need, or

2. Refer to the reference chart below for a quick estimate of how much antifouling paint is required for two coats:

Important: Now that youve stripped yourhull, it is important to inspect for any gelcoatdamage before repainting. Also, consider applyingthe InterProtect System to give your hull a barriercoat to protect from gelcoat blistering.

Top Tips

n Apply an extra coat to all leading and trailing edges,water-line, trim-tabs, outdrives, keel and rudder. High turbulence in these areas tends to wear theantifouling faster.

n Always use the specified amount of antifouling. Under-application can result in premature fouling and costly mid-season haul out.

Proper preparation of the gelcoatThis includes getting all of the antifouling

paint and primers off and removal of as muchgelcoat as necessary to get the hull dry (i.e. theentire gelcoat or just small areas). A professional,who has looked at your boat, should make thisdetermination.

Drying of the hullThis is the most critical step in the process.

If you do not get the hull dry it will re-blister. We recommend a comprehensive washing anddrying procedure.

Application of Epiglass

Epiglass is a solventless epoxy used to sealup the laminate and fill any cloth that has beenvoided of resin.

Application of InterProtect 2000EInterProtect 2000E provides a water barrier to

minimize the possibility of reoccurrence of damageand will act as a tie-coat to the antifouling. Contactour Technical Help Desk to obtain a copy of theInterProtect Bulletin 900.
