Product Information

MVIS™ WCI is designed to help the performance of interior and exterior thin veneer systems. It is used behind the adhesive mortar and is a load bearing, fluid applied membrane. It can be used as a bulk water management system and crack isolation membrane in an MVIS™ system (Masonry Veneer Installation System) when placed under exterior masonry veneer finishes (ceramic tile, stone, manufactured stone veneer and directly over cement backer board). The membrane will keep most of the bulk water through system and minor movements (from thermal, wind loads) of the façade system. Any moisture that may pass through the system will be handled by the primary water resistive barrier or air barrier system.

Equipped with Microban antimicrobial product protection to fight the growth of stain-causing mold and mildew on the membrane.

It can also be used as a component with the air barrier assembly, when used with other wall components within the building envelope. For other options, consult with LATICRETE Technical Services.
