(The following steps are recommended for best results.)
New or Unpainted Surfaces:
New concrete must cure for a minimum of 30 days.
Test for loose, flaking concrete by pressing a piece of masking or cellophane tape at various places, then pull it off with an abrupt action. If the tape does not pull the concrete from the surface, it can be painted. If the existing concrete is removed, the loose concrete should be removed down to a sound substrate.
All holes or cracks must be properly patched with a fast setting hydraulic cement.
Remove mildew stains with BEHR® NO. 62 MULTI-SURFACE CLEANER & MILDEW STAIN REMOVER. Follow all label instructions.
All surfaces must be clean and free of dirt, dust, efflorescence and oil. Clean surface with BEHR NO. 990 CONCRETE CLEANER & DEGREASER. Follow all label instructions.
Remove efflorescence with BEHR NO. 991 CONCRETE ETCHER & RUST REMOVER. Follow all label instructions.
Previously Painted Surfaces:
BEHR NO. 875 BASEMENT & MASONRY WATERPROOFING PAINT provides best results when applied to bare or untreated surfaces. PREVIOUSLY PAINTED SURFACES IN GOOD, REPAINTABLE CONDITION MAY BE PAINTED WITH BEHR NO. 875, HOWEVER, BEHR WILL NOT GUARANTEE THE RESULTS.
Test for loose, flaking paint by pressing a piece of masking or cellophane tape at various places, then pull it off with an abrupt action. If the tape does not pull the paint from the surface, it can be painted. If the existing paint is removed, the loose paint should be removed down to a sound substrate by wire brushing or sanding.
For Exterior application; use BEHR NO. 64 15 MINUTE QUIK-FIX® DECK FINISH REMOVER & WOOD RESURFACER to remove latex or oil-base finishes. Follow all label instructions. For Interior application; use a chemical stripper designed for interior use.
Follow all preparation instructions under "New or Unpainted Surfaces" above.
Stir well before use. Do not thin product. Use with adequate ventilation.
Use product when the surface and air temperature are between 50-90ºF (10-32ºC).
Apply to dry or slightly damp masonry walls. Wipe off any visible moisture with a dry cloth before painting.
Apply using a high quality 1/2"-3/4" nap roller cover or a 4" nylon/polyester brush.
Apply at a spread rate of 75-100 sq. ft. (7-9 m²) per gallon on rough surfaces and 100-125 sq. ft. (9-12 m²) per gallon on smooth surfaces.
Two coats minimum are required:
First Coat: Using a brush or roller, work the waterproofer onto the masonry wall surface making certain to cover any pores or voids.
Second Coat: Using a brush or roller, cover the entire surface. Properly fill any voids left after the first coat. Additional spot application may be needed depending on the porosity of the surface.
Important: If leaking is still present after two coats, it indicates that voids or pinholes are still open. Re-apply product to these areas. DO NOT thin product or apply at a greater spread rate.
Dries to touch in about one hour and can be recoated in four hours. Low temperatures or high humidity conditions will affect drying time. Full cure should be reached in 7-14 days.
