Black Pearl® Sheet Membrane

Black Pearl® Waterproofing System is composed of two primary products:

Black Pearl® | Primer Adhesive

Black Pearl® | Sheet Membrane

These components are based upon the same core formula of select, unoxidized asphalt cement base, butyl rubber, styrene isoprene styrene (SIS), neoprene rubber, styrene-butadiene-styrene rubber (SBS), carbon black, fillers, plasticizers and curing agents. The Black Pearl Primer Adhesive also has an aliphatic solvent that is within acceptable OSHA and EPA current regulations.

Black Pearl® Sheet Membrane is a 55 mil woven polyester fabric providing extra tensile strength and stability. This fabric is impregnated and coated with the Black Pearl® rubberized formula. The compatibility between the two components is 100 percent, with the Black Pearl® Primer Adhesive acting as a catalyst on the sheets and chemically fusing the system elements together (including flashings) into a thick, semi-monolithic waterproof membrane.

Black Pearl® Waterproofing System has the unique ability to be applied to green and damp concrete. It is also compatible with asphaltic products, enabling the restoration of projects that were originally asphaltic based and ties to hot rubberized asphalt. It can be applied at temperatures as low as 0ºF.
