Manufacturer's Description

These products are optimised for absorbing surfaces. Through this, they can be used as an invisible, water- and dirt-resistant and UV stable coating for a porous foundation, regardless of whether the foundation is made of natural stone, concrete, terracotta or clay. Floors, walls, façades or roof tiles, this coating can be applied to all kinds of materials. Given that RSS AGtm and RSS AG Excellenttm only apply an ultra-thin layer to the inside of the pores, the material can still breathe after the application of the coating. In this way, a perfect structural protection is created. The biggest part of the pollution washes off through the rain.

Graffiti resistant:

These high quality coatings are an excellent protection against graffiti for porous silicon dioxide based substrates, like sandstone, concrete, terracotta and clay.
