PRODUCT CURING INFORMATION
• Normally, HERCULINER can be subjected to light foot traffic within 12 hours and should not be
subjected to cleaning or chemical exposure until fully cured, in 3-5 days (approximately 96 hours –
slightly longer for gray HERCULINER).
• HERCULINER takes about 4 days to fully cure: less time in hot humid conditions, and more time in
cold dry weather.
Full curing time only affects the amount of time required to wait before subjecting
the surface to cleaning and chemical exposure. The surface can be subjected to loading well
before this minimum time requirement (see above).
Spray Application
• When using a spray compressor, the operator should always wear a respirator with chemical
absorbing cartridges.
• Make sure to thoroughly mix HERCULINER. A drill with a mixing adapter works best. If needed,
HERCULINER can be thinned up to 15% with xylene (Xylol) only.
• Attach spray gun to compressor line, giving pressure of 40-50 PSI (276-345 kPa). Minimum
requirements of air compressor: 11-16 CFM (18.7-27.2 m
3
/min) @ 50 PSI (345 kPa).
• To initially adjust the air/HERCULINER mix, always start with the air pressure. Then slowly raise
the fluid pressure gradually lowering the air pressure until the desired flow rate and spray is
reached. NEVER open the fluid valve first. This will cause the fluid to back up in the gun due to
the lack of air atomization pressure. Air and fluid pressures should be equal. Always favor the air
pressure side. However, if the air pressure is too high, fluid flow will reduce to zero.
• Before starting the job, spray a few short bursts away from the surface to test that everything is
working properly.
• Spray an even coat over the entire surface to be covered. Be careful not to apply coat too thickly.
• When surface becomes tacky – between 20 minutes and one hour, depending on weather
conditions – spray second coat. Extreme climate conditions of heat, cold and humidity can shorten
or lengthen this period.
• Clean spray gun and wipe off hoses between coats and immediately after job is completed. Use
xylene (Xylol) only.

Important Advice
• Remove any over-spray immediately with xylene (Xylol) or acetone. HERCULINER is very difficult
to remove once cured.
• Solvents released when spraying are flammable. Observe all fire precautions. Proper ventilation is
required.
Repairing HERCULINER
HERCULINER can easily be repaired or over-coated, because it bonds to itself.
• Cut out all damaged HERCULINER to eliminate uneven edges.
• Clean area to be repaired and rough up surrounding HERCULINER with 60-grit sandpaper so that
the new application can get a good grip.
• Clean area with xylene (Xylol) only.
• Brush or spray fresh HERCULINER onto cleaned areas, as per application instructions.
Painting HERCULINER
• A polyurethane-based paint will generally adhere to HERCULINER if it is clean, dry and properly
roughened.
• Tinting of HERCULINER is not recommended.
