Special anti-graffiti polymer coatings have been on the market for several years. They create a hydrophobic seal that closes the pores, preventing the paint from adhering to the undersurface and allowing it to be wiped off. But as a result the building can no longer breathe, augmenting the risk of mold development or salt efflorescence. Because they cannot be removed easily, such coatings also run counter to the principles of conservation, which require that any changes must be reversible. Now, a new breathable coating has been developed by researcher from Fraunhofer Institute for Applied Polymer Research IAP in Potsdam, Germany. The coating provides efficient, all-round protection against attacks by taggers. As part of an EU-sponsored project, the team and partners from the Center of Polymer and Carbon Materials of the Polish Academy of Sciences in Gliwice and Zabrze have developed the new polymer coating.
