Waterproofing your basement can help keep moisture away. Usually a result of water pooling around your foundation, basement water damage can easily be avoided with the application of the Foundation Sealant/Basement Coating.
Inspect surface to ensure it is structurally sound, clean, dry and free of contaminants. Fill any cracks joints, voids that are 1/8” or larger with a patching material like wood filler, concrete patch or expansion joint caulking. Use Liquid Rubber Caulking for gaps and cracks. Concrete: For deep cracks, fill with a Crack Injection Kit – consult a professional if needed to ensure there is no structural damage. Wood: Make sure any organic matter is removed using Deck and Patio Cleaner. Secure raised nail heads, screws and/or loose boards. Remove any loose/flaking material if already coated. Do a test patch to confirm proper adhesion.
Contain the Mess
Set out a tarp or large piece of cardboard to keep all tools and containers on when you are not using them. Have a pail of soap and water, rags and mineral spirits ready in case there is a spill. If a spill happens, use rags to soak it up, cleaning immediately with soap and water. If it is dried, use a razor/scraper to remove. Use mineral spirits to weaken the material and remove with a wire brush or grinder.
*Note: Use mineral spirits sparingly.
Step-By-Step Project Walkthrough
Tip From The Pros:
FOR EXTRA ADHESION, PERFORMANCE AND LONGEVITY AND TO CREATE A MOISTURE VAPOR BARRIER, USE 1 HEAVY COAT OF MULTIPURPOSE PRIMER.
All surfaces must be structurally sound, clean, dry, and free from anything that would prevent proper adhesion. Cracks, joints, voids, etc. (1/8” or larger) should be pre-filled with a suitable patching material such as a high-quality wood filler, concrete patch material or Liquid Rubber Sealant & Adhesive (or equivalent).
Concrete should be cured for at least 28 days.
Be sure to perform a moisture test prior to application.

Detail Work
Liquid Rubber 3-Course-Method: For all cracks less than 3mm (1/8’’), cold-joints, non- monolithic inside/outside corners, pipes, wall/slab, wall/footing and wall/wall junctures apply a thick 6’’ wide coat and embed 4’’ wide Geo-Textile reinforcement fabric followed by a second coat (known as the 3 Course Method). For all cracks greater than 3mm (1/8’’) fill with backer rod, spray foam, expansion joint caulking or patching materials prior to 3 Course Method. Ensure the surface is smooth and flush and that patching materials have cured as per manufacturers recommendation prior to application of your Liquid Rubber Solution.
Tip From the Pros:
FOR BEST RESULTS REMOVE EXISTING PAINTS/COATINGS AND APPLY DIRECTLY TO THE SUBSTRATE.

Masking
Tape-off, block-off, or otherwise mask areas that are not to receive your selected sealant. Remove tape while Sealant is still wet.
4
Prime
Multi-Purpose Primer is needed to provide a moisture vapor barrier, when applied directly to the substrate, or to increase bond to existing coatings.
5
Apply Coating
Apply your selected sealant when temperature is above 10°C/50°F including overnight. Use a brush, roller, or heavy-duty hydraulic piston spray rig (very thick/viscous material) at a final coverage of 50 ft² per G (4.6 sq/m) or 250 ft² per 5G pail to achieve a damp-proof coating. Generally you can apply 2 generous coats per day. Apply the next coat when dry to touch, is uniform in color and nothing is wet underneath. Tacky is OK. Apply all recommended material. Membrane should be a minimum of 12” above finished grade and down the base of the slab/footing.

Remove tape while coating is still wet and close container to secure leftover product. If spillage occurs, soak up as much material as possible with rags. Clean immediately with soap and water. If spill is dried, scrape off as much as possible with a razor or scraper. Use mineral spirits to weaken product and an appropriate tool such as a wire brush or grinder to mechanically remove. If splashed on the skin immediately wash thoroughly with fresh water. If the product has dried on the skin massage the area with medical grade mineral oil, baby oil or edible oil, then wash with soap and water. If irritation persists seek medical attention.
