SOPRASEAL STICK PRIMER is a primer specifically designed to enhance the adhesion of self-adhesive membranes on porous surfaces such as exterior gypsum boards at temperatures above - 30°C (-22°F) for an application with a brush or a roll, and above -10°C (14°F) for an application with a spray equipment. It is composed of SBS synthetic rubbers, adhesive enhancing resins and volatile solvents.
This product can be used on exterior gypsum boards, wood, metal and concrete.
SOPRASEAL STICK PRIMER can be applied with a brush, a roll or spray equipment on dry and clean substrates. It must be thoroughly dry before applying the waterproofing membrane. SOPRASEAL STICK PRIMER must be well shaken before use.
WARNING: KEEP AWAY FROM ALL FLAME OR SPARK SOURCES WHEN SOPRASEAL STICK PRIMER IS DRYING.
