Products Needed for a basement waterproofing system: PermaFlex®LRB (Liquid Rubber Base) and TAV (Thickening Activator)

Step 2 Prime

“Prime” the substrate (surface): Apply 1 coat of PermaFlex® (240 sq ft per gal). Concrete block surfaces need 2 prime coats of PermaFlex® basement waterproofing products because it is more porous than standard poured concrete. The first coat of PermaFlex® penetrates deep to permanently lock and seal within the pores of the concrete. The second coat begins filling the pores, pock holes & pin holes near the surface. PermaFlex® basement waterproofing products permanently adheres to concrete.

Step 3 Patch

3. “Patch” and profile any joints, seams, cracks, holes and rough areas using LRB/TAV mixture. 2-parts LRB (Liquid Rubber Base) is mixed with 1-part TAV (Thickening Activator) to create a thick caulk-like mixture. A 1″ diameter caulk bead of LRB/TAV mixture is applied where the wall meets the floor. Most cracks use a 3/4″ diameter caulk bead. LRB/TAV “Round Caulk Bead Chart
