PSS-20 is a more than 95% biodegradable protector and cleaner used for the removal of graffiti from all porous and smooth surfaces (frescoes, brick, concrete block, stone, plaster, stucco, statues, etc.)
This surface protection is not toxic to humans, animals or the environment.
The PSS-20 has been tested by renowned institutes.


PSS-20 is the ecological and reversible anti-graffiti protection for porous and smooth surfaces, mainly vertical (facades, walls, interiors or exteriors). The protective product is made from plant polysaccharides (natural polymer such as cellulose or starch) and water. It can be used for commercial and residential use as well as for architects. The PSS-20 product is what is called a “sacrificial protection system” (also called temporary system), since the protective film created by the PSS-20 will be removed (sacrificed) during the cleaning of the graffiti, to be then reapplied to the still wet porous or smooth substrate. PSS-20 is patented worldwide and it provides our societies with economic and environmentally friendly protection for our architectural heritage such as: historical monuments, works of art, churches, apartment buildings and even public transport.
