- 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.
- 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.
- Apply a topcoat of PermaFlex (240 sq. ft. per gal.).
