WP-980 is a thin, flexible, load bearing waterproofing system which consists of an elastomeric latex compound along with a reinforcing fabric that combine to form a seamless waterproof barrier under ceramic tile and stone installations.
WP-980 also acts as a crack isolation membrane for these same types of applications.
As a Waterproof Membrane: For use under all ceramic tile and stone installations where a waterproof surface is required. Ideal for all wet areas such as bathrooms, showers, spas & steam rooms, fountains pools, countertops, etc.
As a Crack Isolation Membrane: For interior use, over shrinkage or non-structural cracks up to 3 mm (1/8”). Ideal for use over concrete or concrete-based underlayments, and to cover plywood and concrete backer unit joints.
