A rigid substrate made of Portland cement, aggregate and glass mesh. It provides a hard, durable surface that is able to withstand prolonged exposure to moisture. An ideal underlayment for ceramic tile on floors, countertops, tub decks and outdoor kitchen counters. Homogeneous core has fewer voids and provides a very clean score and snap Can be cut using a standard utility knife instead of specialty tools or expensive power tools PermaBase resists the growth of mold and mildew achieving a panel score of 10, the highest score possible, per ASTM D 3273 1/4 in PermaBase can be used for counters and is ideal for applying directly over laminate or other wood surface countertops PermaBase has a lower moisture absorption rate than other backer boards, which ensures an accurate open time and a better bond The 1/4 in thickness eliminates the need to modify adjacent thresholds when abutting to carpeting, wood flooring and other common flooring materials
