Mapeguard® UM 35: Reshaping the industry

Deerfield Beach, Florida – MAPEI’s Mapeguard UM 35 is a crack-isolation, vapor-management, waterproofing and uncoupling membrane that joins MAPEI’s successful line of uncoupling membranes, providing outstanding performance over challenging substrates.

“Mapeguard UM 35 is made in the USA and is designed for use on both wood and concrete surfaces,” explained Sonya Moste, MAPEI’s Product Manager for crack-isolation, waterproofing, heat and sound-control flooring membranes. “It even works well on tile-over-tile installations.” Mapeguard UM 35 is an excellent vapor barrier and, when used with Mapeguard WP ST sealing tape, it becomes a waterproofing

Made from a lightweight, high-density polyethylene (HDPE) that lays flat when unrolled, Mapeguard UM 35 features a fleece fabric backing that has been engineered for tenacious mechanical bonding to the substrate. “The HDPE surface is slightly rough, which helps create an excellent bond with the mortar,” Moste continued. “It also helps hold the chalk when you snap a chalk line.”

The membrane’s uniquely shaped circular cells fill with material, not air bubbles, when mortar is troweled over the surface. “This ease of trowelability reduces applicator fatigue,” Moste explained. “And the fact that the cells fill on the first trowel pass minimizes the amount of mortar needed to complete the job.”
