1. Repels water, oil, and solvent-based paints on porous mineral building materials 2. Creates a water vapor permeable, hydro- and oleophobic impregnation 3. Provides semi-permanent protection: even after 3 cleaning cycles re-application is not required 4. Protectosil ANTIGRAFFITI® SP is a water-based system.
It is practically free from volatile organic components (VOC). The protection with Protectosil ANTIGRAFFITI® SP provides good weather-resistance and is water vapor permeable. Protectosil ANTIGRAFFITI® SP is a ready to use product. The number of application steps and the amount of Protectosil ANTIGRAFFITI® SP required are a function of the substrate and the desired effect. In general, porous materials require more coats than dense microporous materials. Several coats of Protectosil ANTIGRAFFITI® SP must be applied to provide proper protection against graffiti. Very porous and absorbent surfaces consume more product than smooth, dense, and microporous materials. It is advisable to apply a test patch to determine the exact coverage rate.
