ARDEX 8+9 Rapid Waterproofing & Crack Isolation Compound

ARDEX 8+9 Rapid Waterproofing and Crack Isolation Compound is a best-in-class, two-component, solvent-free, cement-based membrane. Comprised of an acrylic-based liquid compound and a Portland and other hydraulic cement-based powder, ARDEX 8+9 can be applied easily with a paint roller or a brush to produce a highly flexible, waterproof coating.

This coating protects from topside water infiltration and provides an excellent bonding layer for ARDEX tile and stone mortars. When properly installed, ARDEX 8+9 reduces the risk of efflorescence and is IAPMO certified for use as a shower pan.

ARDEX 8+9 can be used for topside waterproofing of all common building substrates including showers, balconies and other wet areas. On interior applications, ARDEX 8+9 can be used over concrete and masonry finishes, existing tile, drywall, cementitious backer boards and plywood on all interior floors or walls prior to the installation of tile and stone.

ARDEX 8+9 is ideal for use on exterior applications over cement and masonry substrates. ARDEX 8+9 also is ideal for crack isolation up to 1/8" (3 mm) when used with ARDEX SK MESH™ Reinforcement Fabric for Waterproofing and Crack Isolation; 1/16" (1.5 mm) when used alone and is recommended as a primer for certain tile and stone applications
