FEATURES AND BENEFITS OF LIQUID MEMBRANE

ACTIVE ADHESION

Integrated chemical adhesion enables mechanical cross-linking to applied surfaces, creating a perfect bond for long lasting protection.

* Drawing is not to scale

Waterproofing

Odorless/low VOC waterproofing that allows you to proceed with your finish within 2 hours of application enabling a speedier project completion.

* Drawing is not to scale

ELONGATION

Up to 400% stretch and elongation providing future crack suppression for years to come.

* Drawing is not to scale

Repair cracks up to 1/4″ wide

Repair existing surface cracks and imperfections to ensure clean and smooth finish application.

* Drawing is not to scale

Repair control joints and cracks wider than 1/4″

Up to 400% stretch and elongation providing future crack suppression for years to come.

* Drawing is not to scale

Stabilization of existing substrates

Repair existing surface cracks and imperfections to ensure clean and smooth finish application.

DRYING / RECOAT TIME

DRYING / RECOAT TIME

Drying times are affected by temperature and relative humidity. The chart represents guidline values but each project is to be treated individually.

The chart represents the time needed in between coats at specified temperature.

CURE TIME

Curing time is affected by temperature and humidity.

For example at only 50º F, a full cure would take 10 days in comparison to at 95º F it would only take 5 days to cure.
