BUTYL 310 is a butyl rubber elastomeric coating designed for the protection of Polyurethane foam, metal, modified bitumen, single ply, concrete and other surfaces. Its formulation incorporates elastomeric butyl rubber and selected additives. Once cured, this sprayed applied polymer provides a durable, seamless flexible waterproof membrane that resists cracking and will allow for the normal expansion and contraction that may take place within the surface of the structure. BUTYL 310 provides excellent UV protection and superb resistance to any moisture penetration.
RECOMMENDED USES
BUTYL 310 is recommended as a protective vapor barrier coating to most surfaces as well as roof applications, including a variety of situations such as polyurethane foam, seams, fasteners, gutters, vent pipe flashings, air conditioning units and expansion joints. Ideal for metal buildings that may contain visible rust.
APPLICATION INSTRUCTIONS:
The suggested application process is airless spray, brush, or long nap roller. Apply BUTYL 310 only to clean, dry, sound surfaces free of loose particles or other foreign matter. Apply two coats of BUTYL 310 to roof or wall allowing 10-12 hours between coats
