Before installing our system, the contractor had a moisture survey done on this roof to ensure there wasn’t wet insulation. If wet insulation is found, it must be replaced before installing our coatings.

After determining the substrate was dry the installer power-washed the roof with more than 3,000 psi to make sure the roof was extremely clean. He then applied one coat of the FABRIC BOND 930 to make sure our top coats adhered to the roofing material. Other appropriate primers for a smooth BUR include the AWS ACRYLIC BONDING PRIMER 905 and NEOPRENE 940.

Often times at this point our Dealer would begin the waterproofing stage of our system but this roof was caught before the leaks began. In this case the building owner was only using the WeatherStar system for preventative maintenance. So the WeatherStar Coatings Installer then sprayed two coats of the ACRYLIC 210 to form a bright white seamless membrane to make sure his customer's roof lasted for years to come. Other AWS coatings suitable to coat a smooth Built Up Roof include our ACRYLIC 211 on roofs that drain well or our BUTYL 310, and URETHANE 520 on roofs that do not drain well.
