3.03 APPLICATION
A. Application may not start until owner/architect has accepted entire surface as to
texture, ponding of water, and drainage.
B. Etch entire surface with 1:4 solution of muriatic acid and water and flush to
neutralize immediately.
C. After flushing has dried thoroughly, for at least twenty four (24) hours under good
drying conditions, spray apply one (1) coat of primer over entire area at a rate of
.03-.04 gallons per square yard.
D. Allow adequate time between applications for prior coat to dry thoroughly before
applying next coat. Primer requires a minimum of two (2) hours of good drying. Color coats

final coat keep all foot traffic off sealed surface. Allow the final coat to cure at least
twenty four (24) hours, under good drying conditions, (at least seventy (70) degrees F.)
before allowing foot traffic on surface. Less favorable conditions will require longer
drying times.

manner in accordance with the manufacturer's standard printed instructions. Prior to white
