Vandex BB 75
Vandex BB 75 is a cementitious, ready-mixed, efflorescence-free surface waterproofer with hydrophobic properties, resistant to water and moisture. Vandex BB 75 is applied to surfaces such as concrete, masonry and render, which have to be sealed and protected against the influence of water and moisture.

Vandex BB 75 is waterproof (tested up to 7.0 bar). It can be employed against active and passive water pressures. Vandex BB 75 is safe to use with potable water. The initial and final bonding capability of Vandex BB 75 is excellent, making it suitable for application to horizontal and vertical surfaces. It is durable, resistant to frost and heat setting, and permeable to vapour. Vandex BB 75 is not a decorative material. Consult Safeguard Europe Ltd technical literature for details. Safeguard Europe Ltd can also provide a design and specification service and it is recommended that they are consulted early in the design process.
