Southcrete™ 1132 One-Part Liquid Waterproofing and Anti-Fracture Membrane is a single-component, water-based, brush or roller applied, thin, load-bearing liquid membrane. It is for use under thin-set and thick bed mortar applications as a waterproof or anti-fracture membrane. The elastomeric properties help reduce the risk of substrate cracks transferring above to the hard surface flooring.
