Does having a membrane change the cure time?
The membrane does not change cure time.
Curing time is not impacted by the membrane because cementitious adhesives cure in the presence of water, not its absence. It’s a chemical reaction and varies according to ambient temperature. The curing time of each adhesive will be stated within its instructions.
We do not recommend the use of adhesive that use solvents and harden by drying out, i.e. ready mixed adhesives, as the membrane is waterproof.
