Vandex BB75 Tanking Slurry

Vandex BB75 is a high-performance tanking slurry for use on concrete, masonry, and render. It can be applied by trowel or spray.

Once cured, Vandex BB75 forms a waterproof coating that has been tested up to 7 bar.  Where an elasticised coating is required, Vandex BB75 can be used in conjunction with Vandex Cemelast or Vandex PK75 elasticising additives.

Where a rapid curing time is required, consideration should be given to the use of Vandex Rapid S.
