Mix only that amount of material that can be used
in a two hour period. In hot weather, plan work for the cooler times of the day.
If using less than full units, proportion the
amounts carefully and mix for 2-3 minutes using a low speed drill, scraping the
bottom and sides of the mixing vessel. DO NOT ADD WATER.
Viscosity will decrease during the first 15-20 minutes at 77°F
(faster at higher temperatures). DO NOT ADD WATER.
Apply Epoxy.com # 441 polyurethane at a spread
rate of 275-300 square feet per gallon to achieve 2.0-2.5 mils dry using roller,
brush, squeegee or airless sprayer. Thicker
application may result in bubbling in the cured film. Recoat time is
approximately 3-4 hours at 77°F. Keep a wet edge at all times.
Use with adequate ventilation. Read material
