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.
