Optimum penetration into surface pores, pin holes, cracks etc.
Provides exceptional adhesion/bonding between membranes & substrate.
IMI Concrete Primer is a general primer for concrete and bricks – used as a prime coat before applying any modified bitumen membranes.
IMI Concrete Primer (ASTM D-41) should be well stirred prior to use. A brush or roller may be used to even apply the primer to the substrate. The primer should be ‘tack-free’ dry, before applying the membrane. Any area that appears lighter should be re-coated with primer. Application should be to vertical as well as horizontal surfaces.
