BASE/TOP COAT: Top Coat, applied feather thin before coloring, and into hairline cracks for crack repair.

APPLICATION METHOD: For hairline cracks use a Cellulose sponge and apply into the crack and wipe away excess…similar to grouting. As a Color Enhancer, use just a small amount on a cellulose sponge and lightly rub just a little on the high spots of the textured surface. Let dry and apply color. Everywhere you applied the mixture will dry lighter and mottle the color and add realism.

WORKING TIME: Average 3 to 5 minutes as it is feather thin in most applications
