SOPRA-FLASH R is a lightweight polyester/nylon composite fabric. SOPRA-FLASH R is used as a reinforcement fabric in COLPHENE H hot-applied rubberized asphalt waterproofing membranes systems. Its absorption capability allows to quickly wet into and become encapsulated by COLPHENE H membrane.
Base sheet membrane
COLPHENE H membrane system is applied with a flat squeegee. Do not use a notched squeegee. Apply the base coat of COLPHENE H to the substrate. Immediately unroll the SOPRA-FLASH R with a 75 mm (3 in) overlap of adjacent sheets and into the base coat of COLPHENE H while in hot liquid state. Avoid the formation of wrinkles, voids or fishmouths. Apply light pressure with a flat squeegee to eliminate air bubbles, wrinkles, etc. Allow fleece to saturate with resin from bottom up. Apply the top coat of COLPHENE H over the SOPRA-FLASH R reinforcement.
