CONCRETE PREPARATION FOR FLOOR COATING:

Acid etching solution will not work properly on greasy, oily, or painted surfaces. This concrete must first be cleaned with either, Northern Aqua-Blue or Northern Scrub-Free, for heavy film buildup removal.

Acid solution should always start at lowest level of a floor usually the drains. Apply in circular fashion out away from drains. Remember acid solution will not work properly when poured on "spent" or "used" acid solution. Acid solution will "foam" or "froth" instantly when poured on the concrete. Slow or no reaction is a sign that the concrete was not ready to be etched. Clean and repeat above procedure.

Muratic and Hydrochloric acids are available commercially at most hardware or pool supply stores. Mix 2 parts water with 1 part acid for good etching. Using a plastic watering sprinkler, apply the mixed acid solution (always add water to the can first) at a spread rate of 50 sq. ft. per gallon. Acid solution must be "worked" into the substrate with a stiff bristle broom to completely agitate the floor. Once acid solution stops frothing (approximately 10-15 minutes) flush the remaining solution to drain and rinse floor thoroughly. "Do not let solution dry". Rinse floor a second time with some household ammonia to neutralize any acid residue that might remain.
