Applying S-20 in Cold Weather



Below is video footage of a GacoFlex S-20 recoat project on a 535,000 sq. ft. commercial roof. The existing roof material is PVC single-ply mechanically fastened on 1-inch ISO; beneath that is BUR and steel deck. Consultants recommended recoating the roof before the insulation became saturated with moisture and the roof membrane could no longer be saved – and a total tear-off could be avoided. The customer verified a 68% cost-savings compared to that of a total tear-off.
