Graffitiguard is a graffiti-resistant formula for coating porous silicate substrates such as sandstone, concrete, terracotta and clay. Once applied, a protective layer less than 100 nm thick (80 000 times thinner than a human hair) bonds with the inner pores of the substrate to leave a smooth, anti-stain, non-discolouring surface layer.

The coating is optically clear, UV stable, chemically inert and extremely durable, with hydrophobic and oleophobic capabilities. It will not peel or flake and is unaffected by extremes of temperatures from –20°C to +350°C.

Features and benefits:

The existing surface quality is preserved, becoming highly water and grease-repellent, and resistant to colour seepage and abrasion.
Paint and other contaminants are unable to adhere to the surface.
Cleaning becomes much easier and less frequent – typically required 50–70% less often – and the coating withstands high pressure (up to 50–60 bar).
The lifespan of the substrate is extended because of reduced cleaning cycles.
The surface remains clean and will not discolour.
