PermaRock Scratch Render (cement-lime render / monocouche / ashlar effect)

PermaRock Scratch Render is a pre-mixed render based on cement limestone and specially selected, lightfast and UV stable mineral pigments. It is supplied as a dry powder, preblended, ready mixed, cement-lime based exterior through-colour render containing a silicone water repellent agent. This monocouche type render is for single or two coat applications to brick or blockwork masonry and onto a PermaRock reinforced base coat. The render is weather resistant and yet provides excellent water vapour permeability, allowing treated walls to breathe. Scratch Render can be applied in thick layers which enable the creation of rustication and ashlar effects. The water repellent surface reduces water absorption and improves resistance to algae, soiling and frost damage.
