Blanke Secumat Ultra Thin Crack Isolation Membrane

Crack Isolation Made Thin, Tough, and Easy.

Blanke SECUMAT is a tear-proof, low-profile uncoupling membrane designed to simplify tile installations over wood or cement substrates. Built with reinforced fiberglass mesh layered between durable polyester fabric, SECUMAT delivers dependable crack isolation while keeping your build-up to a minimum.

Lighter, leaner, and easier to install than traditional uncoupling mats, SECUMAT is the smart choice for both new construction and renovations—especially when elevation matters. It uses significantly less thinset than other uncoupling options, saving both time and material costs.

Ideal for residential and commercial floors or walls, SECUMAT provides a secure bond for ceramic, porcelain, natural stone, and even mosaic tiles.
