Products / GenFlex WaterStop Sealant

GenFlex WaterStop is a one-component, low-viscosity, self-wetting butyl-blend mastic used as a sealing agent between GenFlex membranes and substrates where the membrane is terminated with a compression-type seal, and it remains tacky in that use. It is supplied in 11 oz (326 mL) tubes, 12 per carton.
