• The 1/4 in thickness eliminates the need to modify adjacent thresholds when abutting to carpeting, wood flooring and other common flooring materials

• 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
