Masonry Supplies That Matter

Liquid-Flash is formulated using a high-performance silyl-terminated polyether polymer technology (STPE). It is a single component, moisture cure elastomeric waterproofing membrane that is applied and tooled to create a long-term moisture-proof barrier. Liquid-Flash shows excellent resistance to UV degradation and extreme environmental conditions. Can be applied to damp or wet substrates without outgassing or “bubbling.” Safe to apply in wet conditions when rain is eminent, as it will not wash off like other sealants. Because Liquid-Flash is 100% solids, it will not shrink or crack. It is compatible with most common building materials, including concrete, plywood, concrete masonry, brick, gypsum sheathing, wood, and cement-based sheathings.

Liquid-Flash is available in 20 oz. sausages
