Lucas #4700 Modified Urethane Liquid Waterproofing Membrane is a high solids, solvent free, moisture cure coating for below grade foundation walls. #4700 may be applied to concrete and masonry surfaces to provide a seamless waterproof membrane. This product contains no water, solvents or economizing extenders such as asphalt or coal tar.


For application to foundation walls, all seams and penetrations should be sealed with Lucas #4400 or #9600 modified polyurethane sealants. Allow 2 to 4 hours before coating over sealants. Embed 12” polyester reinforcement fabric on all inside and outside corners, apply Lucas #4700 at 1.5 gallons per 100 square feet and immediately embed fabric. Dry brush the fabric smooth. Apply an additional 1.5 gallons of #4700 on top of the fabric to fully encapsulate it. Apply base coat of #4700 at a rate of 2 gallons per 100 sq. ft. Allow coating to cure, typically 2 to 4 hours, then apply second coat at the rate of 2 gallons per 100 sq. ft. For best results, apply coating in a multi-directional fashion. Use #4700 as it comes from the container, no thinning is necessary with this product. Apply by brush or roller. The finished film will be approximately 60 mils thick. #4700 may be applied in 60, 90, and 120 mil systems.

Shelf life: One year from the date of manufacture. Store in a cool dry place. High temperatures and high humidity during storage will shorten the product’s shelf life.
