Blue 92 Anti-Fracture Membrane is a two–part system consisting of a liquid rubber and reinforcing fabric. When cured, it forms a highly flexible membrane. While the thin bed method of tile installation provides many advantages, this method can be affected by problems with shrinkage cracking in concrete and other types of substrates. Cracks can telegraph through the tile and/or grout joints. To reduce or eliminate cracks in tile work, a flexible membrane should be applied to the cracked substrate prior to the installations of ceramic tile, marble and stone.
