A high quality, single component, low VOC, water-based, textured acrylic, protective and decorative coating for masonry surfaces. Based on an advanced micropolymer resin binder which cross-links to afford excellent durability, it effectively waterproofs the surface for many years, yet allows high levels of entrapped substrate moisture to escape without causing blistering or delamination. The resin-rich coating encapsulates the individual textured particles without leaving thin areas over particle peaks. It has an elastomeric formulation, bridging hairline cracks and facilitating substrate movement without cracking or flaking. It is available in a range of attractive colours, and an active biocide inhibits mould and lichen growth.
