Product Details

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 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.

Customer Questions & Answers

Can it be use on shower walls?

Asked by: Nic
Mapelastic CI is not suitable for use in showers or on vertical surfaces. We would recommend using Aquadefense as it is a waterproofing membrane that is more suitable for this purpose and provides crack isolation for in-plane cracks up to 1/8 in.

is mapelastic CI water proof like Aquadefence

Asked by: george
Mapelastic CI is a quick-drying crack isolation membrane for use under ceramic tile or stone in both residential and commercial environments. It is not safe to use where excessive substrate moisture and/or negative hydrostatic pressure exists. The maximum allowable moisture is 8 lbs. per 1,000 sq. ft. per 24 hours per ASTM F1869 or up to 85% relative humidity measured by probes.
