PSS 20

PSS20 is a biodegradable protector used at more than 95% as an anti-graffitis on all porous and smooth surfaces such as brick, cement blocks, stone, rough cast, stucco, statues, etc.

The PSS 20 film is open for water vapour diffusion, is normally indiscernible to the eye and is completely reversible using hot water.

PSS 20 is completely safe for humans, animals and the environment.

PSS 20 has been comprehensively tested by well-known institutes.

PSS 20 is particularly suitable for natural stone, artificial stone, concrete as well as non-porous surfaces.
