For maximum durability, the surface must be clean, free of dirt, oil, chalk and other foreign material.
Concrete, concrete decks, concrete floors and concrete walkways
New concrete must age for a minimum of 30 days.
Cool temperatures and high humidity may require a longer cure time.
Remove all grease, oil, and wax with T.S.P. solution. (One pound of T.S.P. to 1 gallon of water.)
Scrub with a stiff broom until the surface is thoroughly clean.
Rinse thoroughly with clear water. If necessary, etch all unpainted cement with A-250 acid etching gel, let stand five minutes then rinse clean with water.
After etching, neutralize the acid with baking soda or soda ash then rinse thoroughly with water. A properly etched concrete surface should resemble the texture of medium sandpaper. Let dry thoroughly before applying the coating.
A-1100 may be used as its own primer.
To use as a primer, add 1-pint water to 1 gallon A-1100.
Previously Painted Surfaces
