Step by Step Basement Waterproofing

The following steps will show you How to Waterproof a Basement with SANI-TRED®.

Products Needed: PermaFlex™, LRB (Liquid Rubber Base) and TAV™ (Thickening Activator)

  1. Prepare the surface area for waterproofing. Make sure the walls of the surface area are clean, dry, and free of foreign matter or crumbling material.
  2. Prime the surface area. Apply one coat of PermaFlex™ (240 sq. ft. per gal.)
    -- Concrete block requires two prime coats of PermaFlex™ due to its porous nature.
  3. Patch and profile any joints, seams, cracks, holes or any rough areas using a LRB/TAV™ mixture (two parts LRB/one part TAV™).
    -- Apply a 1’’ diameter caulk bead mixture where the wall meets the floor.
    -- Most cracks can be filled with a ¾” diameter caulk bead mixture.
  4. Apply a topcoat of PermaFlex™ (240 sq. ft. per gal.).
