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.

  • PSS 20® is over 95% biodegradable, contains zero VOCs or solvents and is made from plant-based materials. It is fully reversible and is removed with warm water.
