A 2 part system that forms a highly flexible, full coverage membrane that reduces crack transmission from the substrate to floor finishes. Adds no appreciable thickness to floor construction, and is ready to receive floor finish in just a few hours. Easy to install, no odors and cleans up with water. LATICRETE Blue 92 Anti-Fracture Membrane inhibits the growth of stain-causing mold and mildew in substrates with Microban antimicrobial product protection. ASTM C627 Rated "Extra Heavy" Service. Applicable standard ANSI A118.12.
LATICRETE Blue 92 Anti-Fracture Membrane is a two-part system consisting of a liquid rubber. 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.
Coverage:
* Approximately 300 ft2 (28 m2) at 20 mil thickness per full unit.
Uses:
- For interior or exterior use on floors and walls whenever hairline cracking or ?spiderwebbing? occurs in the substrate.
- For use over shrinkage and other non-structural cracks up to 1/8" (3 mm).
- Typical applications are over concrete slabs (suspended or on grade) in malls, lobbies and residential applications under ceramic tile, marble and stone.
- Use to cover joints in plywood underlayments, cement backer boards, and concrete masonry on floors and walls.
- Also use over concrete floors and underlayments with radiant heating systems.
Advantages:
- Reduces crack transmission in ceramic tile, thin brick, marble and stone installed using thin-set method. Also ideal for use under thin resin Terrazzo.
- Inhibits the growth of stain causing mold and mildew with Microban antimicrobial protection.
- Thin-adds no appreciable thickness to floor construction; install tile with LATICRETE Polymer Fortified Thin-Set Mortar directly to cured membrane.
- "Extra Heavy Service" rating per TCNA performance levels (RE: ASTM C627 Robinson Floor Test).
- Easy to Apply?goes on quickly with paint brush or roller; no mixing or special equipment required.
- Fast Cure - dries in a few hours to receive finished surfacing.
- Easy Cleanup-cleans with water while fresh.
- Safe-no solvents or harsh fumes, non-flammable.
Suitable Substrates:
- Exterior glue plywood*
- Concrete
- Mortar beds, renders
- Cement backer board**
- Cement terrazzo***
- Ceramic Tile and Stone***
- Concrete masonry
* Interior applications only.
** Consult cement backer board manufacturer for specific installation recommendations and to verify acceptability for exterior use.
*** If skim-coated with a LATICRETE Latex Thin-Set Mortar.
