Surface Preparation

All substrates (including the ELIMINATOR® Membrane) must be clean, dry and structurally sound. They must be free from laitance, oils and any other surface contaminants.

Application

Coverage

The theoretical minimum coverage rate for TWC is 20ft²/gal at 3/8” (375 mils) WFT or at a required specified thickness.  At approximately 3.6 US gallons/pail (including catalyst), each pail will yield 70.6 sq ft. Yields and consumption rates are theoretical and make no provision for waste.

Overcoating

TWC can be installed as soon as the initial cure (1 hour) of the ELIMINATOR® membrane has taken place. There is no critical overcoating window as the TWC material chemically bonds to the ELIMINATOR® membrane or to itself. The existing surfaces are required to be clean and dry.

Colors

Asphalt Gray

Cleaning

All tools and equipment should be cleaned with acetone after use and before the material is allowed to cure.
