Protectosil ANTIGRAFFITI® SP is an aqueous silane system that makes porous mineral building material surfaces hydro- and oleophobic.
Scope of Application
Protectosil ANTIGRAFFITI® SP may be used as a graffiti repellent on non painted mineral building materials such as:
Sandstone (exeption: Udelfanger sandstone)
Sand limestone (natural stone)
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.
General Directions for Using Protectosil ANTIGRAFFITI® SP
Protectosil ANTIGRAFFITI® SP is a water-based system. Therefore it should not be applied at temperatures below 3 °C. Both surface and ambient temperatures should be between 5 °C and 40 °C during application. Please shake the Protectosil ANTIGRAFFITI® SP before the application in order to redisperse precipitated material.
