Fiberglass
Good adhesion can be obtained on unweathered gel-coated glass, rough fiber, side molded glass
and smooth-mold resin-side glass. The surface should be free of oils, waxes and other production
additives, and then sanded to remove all gloss, leaving a rough surface.
GENERAL APPLICATION
HERCULINER may be applied with a brush, roller or spray gun. A roller will provide the roughest final
texture; a spray gun will provide the least texture.
HERCULINER can be applied between 32°F and 95°F (0°C and 35°C).
Before applying HERCULINER, it is important that the surface to be coated is completely clean
(see BED SURFACE PREPARATION on page 3).
Mask all areas not to be coated. Remove masking tape immediately after application of the second
coat.
FIRE HAZARD
HERCULINER contains flammable solvents. Ensure proper ventilation and fire precautions.
Roller Application
Apply HERCULINER with the special open foam stipple roller included in the kit. Extra roller covers
are available at your local home supply outlet (i.e., FoamPRO textured paint roller #58).
Apply the first coat as a thin coat to cover. When the surface is touch dry or no longer tacky (usually
within 1-4 hours – slightly longer for gray HERCULINER), apply the second coat. Extreme climate
conditions of heat, cold and humidity can shorten or lengthen this period.
Failure to apply two complete uniform coats will compromise the durability and
reduce the longevity of the HERCULINER truck bed coating.
Roll gently to extend the life of the roller cover.
To avoid “mud cracking,’’ do not apply HERCULINER too thickly. Pour only xylene (Xylol) thinner/
cleaner over rollers between coats so rollers will not dry out.
Brush Application
HERCULINER can be applied with a soft paintbrush in two coats at right angles to one another.
(HERCULINER is not a paint, and should be laid onto the surface, in one direction, not brushed out
as an oil or latex paint.) Between coats, clean the brush only with the recommended thinner/cleaner
xylene (Xylol). The second coat can be applied as soon as the first coat is touch dry (usually within
1-4 hours – slightly longer for gray HERCULINER.) Extreme climate conditions of heat, cold and
humidity can shorten or lengthen this period.
Coverage (Two Coats)
One quart (0.9 L) covers a flat area of about 15 square feet (1.4 square meters). One gallon (3.8 L)
covers 55-60 square feet (5.1-5.6 square meters), with a final dry coat thickness of 1/16-1/32 in.
(1.6-0.8 mm).
Important Advice
• HERCULINER should be stirred thoroughly before applying (preferably with an electric paint
mixer).
• Stir periodically to maintain rubber granules in suspension.
• To avoid “mud cracking,” do not allow HERCULINER to pool.
• HERCULINER is a moisture-cured product. An open or partially used can will thicken and
eventually become unusable.
• If the product thickens slightly, it can be thinned by using up to 10% of the recommended
thinner/cleaner xylene (Xylol) without affecting performance. Use only xylene (Xylol) to dilute
HERCULINER, clean rollers, brushes, spray guns and hoses.
Other solvents can cause product failure. Do not dilute HERCULINER or clean
rollers, brushes or spray guns with alcohol or lacquer thinners.
• Once the consistency of the product has become pasty, it should be discarded.
