Take durability to new heights with this waterproof coating
GacoFlex U91 is a liquid-applied waterproof coating with diverse applications. Use this single-component, aromatic waterproofing membrane over metal, asphalt, and single-ply roofing systems, or over plywood and concrete as part of pedestrian and vehicular decking systems. GacoFlex U91 may also be used in shower pan liner applications. GacoFlex U91 is the ideal urethane coating solution for rejuvenating existing roofs or protecting traffic surfaces that require high durability and impact resistance. U91C is an additional option available, which is Low-VOC Compliant.
Roof Coating Applications
GacoFlex U91 provides a weathertight seal that protects the substrate from degradation caused by UV, water, and other normal weathering hazards. Apply a top coat with GacoFlex UA6000 Aliphatic Urethane to add additional long-lasting reflectivity to your roof.
GacoFlex U91 may be brush-applied, rolled, or spray-applied and meets the requirements of Florida Maintenance coating specifications (Note: these are pending code compliances). Three coats are recommended for most roof coating applications. The coating surface can generally receive another coat within 10-12 hours, and may be walked on within 24 hours.
GacoFlex U91 may also be combined with GacoRoofFoam for a total roof replacement solution.
Decking Applications
Wherever you apply GacoFlex U91, you can trust its proven track record in the decking and waterproofing space. Two coats are recommended for most decking applications. The coating surface can generally receive another coat within 10-12 hours, and may be walked on within 24 hours. U91 for pedestrian and vehicle decking exceeds requirements of ASTM C957 Standard for High-Solids Content, Cold Liquid Applied Elastomeric Waterproofing Membrane with Integral Wearing Surface. It also complies with the IBC 2020 and IRC 2020.
