IBITOL HS is a solution of bitumen in an organic solvent. The solvent in the bituminous solution has the property to dry quickly, a thin layer of bitumen remains. Due to the low viscosity of the solution it penetrates well into the pores of the concrete and gives good adhesion of the waterproofing material. It is used as a cold bituminous coating for all surfaces, onto which bituminous waterproofing is laid. It is applied with a roller or a brush onto a clean, dry and dusted surface. Usage of the coating is from 0,2 to 0,3 l/m2.
