Blanke Securmat Tile Underlayment

Size *

Blanke Securmat is an uncoupling tile underlayment membrane that provides a secure bonding surface for ceramic tile and natural stone floor coverings. Blanke Securmat can be used on interior floors and walls. Securmat also provides superior crack isolation protection on concrete substrates. If the substrate may be subject to lateral movement of any kind, the crack isolation properties will help protect and prevent damage to the tile covering. This product is extremely light weight, thin, and easy to install. Because it features such a thin, low elevation, it requires much less thinset mortar than most other rolled uncoupling products.
