BITUMAT BITUFAST is a cold applied general purpose  roofing primer, formulated with highly pliable, flexible bitumen, select petroleum solvents and compounded with wetting and saturation addiditives. 


BITUMAT BITUPRIME roofing primer  is a universal primer for concrete, smooth asphalt roofs, brick and metal surfaces. Used as the priming coat before applying any of BITUMAT's coatings, flashing compounds, patching compounds and modified membranes.

Select solvents allow for optimum penetration of BITUMAT BITUPRIME into the surface pores, pin holes and cracks.
The special wetting agent allows for better saturation, dust absorption and adhesion, thereby preparing the surface for a permanent and durable bond between the substrate and coating or membrane.
When applied over weathered asphalt , BITUPRIME rejuvenates and revitalizes the existing cracked and brittle surfaces, thus preparing them suitably for initiating any maintenance or repair operation.


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.

Exceeds the performance requirements of ASTM D-41 .


Tools : Clean with kerosene
Hands : Use a hand cleaner or kerosene followed by soap and water.
