SOPRAFLASH™ UN is an uncured neoprene flashing material. SOPRAFLASH UN is used in conjunction with COLPHENE® H and COLPHENE H-EV hot rubberized asphalt systems at expansion joints and exposed flashing membranes, including vertical walls, penetrations and drains.
Install SOPRAFLASH UN in a solid coat of COLPHENE H or COLHENE H-EV in accordance with recommended flashing details. Press SOPRAFLASH UN into the bitumen while it is hot, taking care not to stretch the membrane or leave air pockets. Overlap successive layers three (3) inches (76 mm).
