How To Waterproof a Basement
Step by Step Basement Waterproofing:
The following steps will show you How to Waterproof a Basement with SANI-TRED®.
Step 1: Prepare
"Prepare" the substrate (surface): Make sure it is clean, dry, free of any previously applied products, foreign matter and loose or crumbling material when building a waterproof basement.
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
"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”
Step 4: Topcoat
