Owing to its composition of cement, quartz with graded grain-size distribution and selected additives, Vandex BB 75 is a cementitious, ready-mixed surface waterproofer. It can be employed against active and passive water pressures.
The initial and final bonding capability of Vandex BB 75 is excellent, making it suitable to be applied to horizontal as well as vertical surfaces. It is durable, resistant to frost and heat after setting, but all the same permeable to vapour. Vandex BB 75 is also tested for use in contact with drinking water.
Applied as corrosion protection, it not only enhances rebar corrosion protection, but also improves adhesion to subsequently applied Vandex repair and coating mortar. It forms a hard coating, is resistant to frost and de-icing salts, allows vapour diffusion and reduces CO2 penetration.
Vandex BB 75 can be applied with brush, trowel or suitable spray equipment onto the following:
