S.S.-B4

S.S. B4 is a quick drying solvent based low viscosity bitumen primer, it is used as a primer coat on masonry and concrete substrates to block superficial dust and porosity and to improve the adhesion of bitumen based membranes and coatings. S.S. B4 is low in viscosity, which allows it to penetrate into the concrete pores and improve the adhesion between the membrane and the concrete surface. In addition to that, the primer also acts as a binder for the dust particles which gets accumulated on the concrete surface even after cleaning.
