Step-By-Step Project Walkthrough

Apply each coat in an alternate direction to the last coat to ensure even coverage.
Prepare Your Space and Gather Your Materials
Make sure your surface is totally clean, dry, and free of all matter. Gather all the products you’ll need. Do an inspection and cleaning of the area.
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.
Masking
Tape-off, block-off, or otherwise mask area’s that are not to receive Foundation Sealant.
Prime
Multi-Purpose Primer may be required to bond to the existing coating. A test patch is recommended to confirm adhesion prior to full application.
Apply Coating
Apply Foundation Sealant when temperature is 10ºC/50°F and rising. Use a brush, roller or heavy duty hydraulic piston spray rig (very thick/viscous material) at a final coverage of 20 ft² per G (1.9 sq/m) or 100 ft² per 5G pail (40-60 mils, 1-1.5mm). Generally you can apply 2 heavy coats per day. Apply 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.

APPLY NEXT COAT WHEN DRY TO THE TOUCH WITH NOTHING WET UNDERNEATH AND IS UNIFORM IN COLOR.
Inspect and Protect
Inspect for pinholes, blisters, voids, thin spots or other defects. Repair as necessary. Allow 48 hours to dry before backfilling. It is recommended to apply protection board or drainage board to protect your coating from other trades and work, during backfill, and from thermal expansion and contraction during its life.
Clean Up
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.
