Mapelastic CI

Mapelastic CI

Professional, Roller-Applied Crack-Isolation Membrane

Mapelastic CI is a premixed, liquid-rubber, quick-drying crack-isolation membrane for installation under ceramic tile or stone in residential and commercial interior and exterior environments. Mapelastic CI meets ANSI A118.12 requirements and prevents nonstructural, in-plane floor cracks up to 1/8" (3 mm) from transferring through grout, ceramic tile and stone. Once it has dried after about 30 to 50 minutes, Mapelastic CI is ready to receive most MAPEI polymer-modified or epoxy mortars.

  • Quick-drying: Allows tile/stone installation after 30 to 50 minutes
  • Easily applied with roller or brush
  • Convenient and versatile: Bonds to a wide range of floor surfaces
  • No odor: Great for confined spaces
  • Prevents in-plane floor cracks from transmitting through tile or stone
