Maxxon and the Tile Council of North America recommend an anti-fracture membrane (ANSI A-118, 12) to be installed over all poured gypsum underlayments prior to the application of all tile or stone installations. Anti-Fracture membranes help reduce cracking caused by structural movement.
Mer-KreteTM Fracture Guard 5000 is a one step mold resistant anti-fracture membrane composed of a modified latex elastomer that produces a monolithic surface. Its thin section (approx. 30 mils) and excellent elongation will inhibit the transferral of cracks from the substrate to the finished surface. The membrane is installed in a semi-fluid state and can be applied to any form or irregular shape.
Fracture-Guard 5000 may be installed over any sound Maxxon approved underlayment to receive ceramic, quarry, porcelain and stone tiles and is ideal for residential and commercial applications. When installed in accordance with manufacturer's specifications, Fracture-Guard 5000 will inhibit cracking caused by movement in the subfloor when tile and stone overlays are used. Fracture-Guard 5000's adhesion properties are enhanced when applied over Maxxon overspray. Overlays should be adhered using Mer-Krete Latex 200 and Filler 211 or Thin-Set 710 or any Mer-Krete latex fortified mortar to ensure compatibility. For positive waterproofing use Mer-Krete Hydro-Guard 2000 Waterproofing Membrane.
