Crack Isolating Uncoupling Membrane


The Backer-lite crack isolating uncoupling membrane allows the subfloors of your home to absorb compressional and tensional stress caused by weather, settling foundations and everyday wear and tear.

Its superior design allows for just one pass of thinset to be used which saves vast amounts of time and setting material. Without the membrane, tiles will typically crack and deteriorate but with the Backer-lite waterproof membrane, you can rest assured that your investment will remain beautiful for years to come. Once the subfloor can be walked on, tiles can be laid immediately. For renovations and new construction, Backer-Lite offers maximum installation reliability and is quick and easy to install. Flooring use only.

BACKER-LITE Decoupling Membrane
Backer-lite Layer Structure:
  1. Textured mesh — optimum tensile adhesive strength.
  2. Optimized dimpled geometry — less adhesive consumption.
  3. Woven special polypropylene underfleece — higher fleece stability for better adhesion to the laying substrate.

Backer-lite is a versatile product that offers many benefits for installation professionals. Its lightweight design makes it easy to transport and maneuver, while its waterproof construction makes it ideal for use in wet areas. Additionally, the mesh top layer provides excellent adhesion strength, allowing Backer-Lite to be used over multiple substrates. The product’s versatility and easy-to-use design make it a great choice for a variety of installation projects.
