PSS 20
GRAFITTI PROTECTION
PSS 20® is a breathable, fully reversible, and virtually invisible protection system engineered to guard surfaces from graffiti, adhesives, gum, heel marks, and airborne soiling. Tailored for use on masonry, concrete, stone, and mineral-painted substrates, it works equally well on interior and exterior facades.
Non-yellowing (stays clear over time)
Completely reversible
Indiscernible / minimally changes surface appearance
Allows vapor permeability (i.e. does not block moisture / “breathability”)
UV and weather resistance
Over 95 % biodegradable
Zero VOCs or solvents; made from plant-based materials
Chemically non-reactive (i.e. inert with respect to the substrate)
Easy removal of soil/graffiti with warm water washing (i.e. low impact cleaning)
No toxic gases released upon decomposition / under heat
Suitable for protecting delicate or historic surfaces
Protects murals and public art (i.e. used in conservation / art contexts)
Formulated as a high-viscosity vegetable polysaccharide solution in water, PSS 20® is completely biodegradable and benign to humans, animals, and the environment. With no volatile organic compounds or solvents, it maintains vapor permeability while providing discreet, powerful surface defence.
