K Rend HPX Base:

A “high polymer” basecoat for ultra high performance onto unusual substrates which require greater flexibility and adhesion. It is used over lightweight blockwork (with alkali resistant reinforcing mesh incorporated) or brickwork (with the use of R7 Acrylic Primer) as a primary coat for K Rend finishes. K Rend HPX Base is Kitemarked to BS EN 998-1 and is IAB approved.
