BITUMAT BITUFAST is a premium quality, cold applied, fast curing primer, formulated with a highly pliable, flexible bitumen and select fast drying solvents and compounded with wetting and saturation additives.
BITUMAT BITUFAST is a universal primer for concrete, smooth asphalt roofs, brick and metal surfaces. It is used as the priming coat before applying any of BITUMAT’s elastomeric membranes and coatings.
BITUMAT BITUFAST is fast curing and hence:
Dust is not trapped whilst wet. Time interval between coats is less, resulting in greater efficiency and better output. 100% evaporation of solids is achieved which is specially essential when using self-adhesive membranes. Greater & stronger adhesion / bonding. Does not require heating, thinning or mixing, thereby saving labour costs. When applied over select asphalt, allows for proper penetration into the surface pores, pin holes, cracks and cures rapidly, preventing work delays and surface contamination. When applied over weathered asphalt, it rejuvenates and revitalizes the existing cracked and brittle surface, thus preparing suitably from initiating any maintenance or repair operation. When applied over stable homogenous asphalt, does not exude or bleed and hence forms a more durable bond.The surface must be thoroughly cleaned, all dust, dirt, loose coating, oil and grease must be cleared and the surface should be dry before priming. It can be applied with a roofing brush, roller, squeegee or airless spray equipment at the recommended coverage rates.
Concrete and metal : 0.2 - 0.3 L/M2
Smooth asphalt : 0.3 - 0.5 L/M2 Mineral granule surfaces and wood : 0.6 - 0.8 L/M2 Coarse aggregate : 0.8 - 1.0 L/M2The underside of the membrane should be torched just enough to superficially melt the bitumen. Excessive heating may damage the re-inforcement. Overlaps should be re-heated from the top and re-sealed with a trowel to ensure seam integrity. For details of installation methods and flashing requirements, consult the relevant BITUMAT Systems Design and Installation Manual.
Bitumat was founded in 1984 but its roots go back to 1975 when the founders became involved in the roofing waterproofing industry as dealer and applicator in Saudi Arabia for a major manufacturer from the U.S.A.
