APPLICATION PROCEDURES

Surface preparation must be completed as indicated.

Mixing Instructions: Stir each component with low speed power agitation prior to mixing. Mix 3 parts Part A (white) to 1 part Part B (black) by weight (premeasured components). Mix with low speed drill and Jiffy Mixer for approximately three minutes until uniform gray with no white or black streaks.

Temperature:Do not apply product when ambient or surface temperatures are below 35°F (1.7°C). Surface temperature must be at least 5°F (2.8°C) above dew point.

Apply paint at the recommended fi lm thickness and spreading rate as indicated below:

Recommended Spreading Rate:Coverage: 1" cove ~ 38 lf/gal

3" cove ~ 10 lf/gal1 mil wft/dft ~ 1604 sf/gal

50% RHTo touch: 6 hours 4 hoursTo recoat:

minimum: 12 hours 6 hoursmaximum: 4 days 2 days

To cure: 7 days 7 daysIf maximum recoat time is exceeded, abrade surface before recoating.Maximum recoat time is shorter when using polyurea topcoat, refer to topcoat data page.Hardening time is temperature, humidity, and fi lm thickness dependent.Pot Life*: 50 minutes 30 minutes*@ 90°F/32°C, Pot Life is 20 minutes

Sweat-in-Time: None

Application of coating above maximum or below minimum recommended spreading rate may adversely affect coating performance.

CLEAN UP INSTRUCTIONS

Clean spills and spatters immediately with Reducer R7K54. Clean tools immediately after use with Reducer R7K54. Follow manufac-turer's safety recommendations when using any solvent.


PERFORMANCE TIPS

Spreading rates are calculated on volume solids and do not include an application loss factor due to surface profi le, roughness or po-rosity of the surface, skill and technique of the applicator, method of application, various surface irregularities, material lost during mixing, spillage, overthinning, climatic conditions, and excessive fi lm build. No reduction of material is recommended as it can affect fi lm build, appearance, and adhesion.

Do not mix previously catalyzed material with new.

Do not apply the material beyond recommended pot life.

Check surfaces of primer, FT910, and subsequent coats for amine blush (oily fi lm). If detected, remove before applying the next layer or coat.

For fi lling larger defects in concrete, one to four quarts of 30 to 100 mesh aggregate may be added per gallon of mixed FT910, depending on the size of hole and slump required.

Ambient air cured FT910 is acceptable for use on interior of potable water storage tanks and reservoirs when overcoated with an ANSI / NSF Std. 61 certifi ed Sherwin-Williams coating.

Refer to Product Information sheet for additional performance characteristics and properties.

APPLICATION PROCEDURESSurface preparation must be completed as indicated.Mixing Instructions: Mix components only after all surfaces are completely prepared and ready to be coated. Thoroughly agitate each component using low speed mechanical agitation, i.e., Jiffy Blade model ES. Then combine 2 parts by volume of Part A with 1 part by volume Part B. Using mechanical agitation, Jiffy Blade ES, thoroughly mix material for three minutes at 250 rpm. Only mix full units. Be sure to mix material from the bottom and sides of the containers. Apply paint at the recommended fi lm thickness and spreading rate as indicated below:

Drying time is temperature, humidity, and fi lm thickness dependent.Pot Life: 45 minutesSweat-in-time: None required

Application of coating above maximum or below minimum recommended spreading rate may adversely affect coating performance.

CLEAN UP INSTRUCTIONSClean spills and spatters immediately with Reducer #54, R7K54. Clean tools immediately after use with Reducer #54, R7K54. Follow manufacturer's safety recommendations when using any solvent.


PERFORMANCE TIPS

When using spray application, use a 50% overlap with each pass of the gun to avoid holidays, bare areas, and pinholes. If necessary, cross spray at a right angle

Spreading rates are calculated on volume solids and do not include an application loss factor due to surface profi le, roughness or po-rosity of the surface, skill and technique of the applicator, method of application, various surface irregularities, material lost during mixing, spillage, overthinning, climatic conditions, and excessive fi lm build.

No reduction of material is recommended as it can affect fi lm build, appearance, and adhesion.

Do not apply the material beyond recommended pot life.

Do not mix previously catalyzed material with new.

In order to avoid blockage of spray equipment, clean equipment before use or before periods of extended downtime with Reducer #54, R7K54.

Refer to Product Information sheet for additional performance characteristics and properties.

Performance tiPs

Stripe coat all crevices, welds, and sharp angles to prevent early failure in these areas.

When using spray application, use a 50% overlap with each pass of the gun to avoid holidays, bare areas, and pinholes. If necessary, cross spray at a right angle

Spreading rates are calculated on volume solids and do not include anapplicationlossfactorduetosurfaceprofile,rough-nessorpo-rosity of the surface, skill and technique of the applicator, method of application, various surface irregularities, material lost during mixing, spillage, over thinning, climatic conditions, and excessive filmbuild.
