White coating, latex-based, with particular mineral powders that, thanks to their insulating features, keeps the surfaces warmer, eliminating any thermal bridge.  There is a +5°C difference between a surface treated with C.W.C. Stop Condense and the one treated with a traditional paint.  These extra heat degrees also prevent the air from condensing onto the wall, even if there is a relative humidity inside the room (up to 90%), eliminating in this way the formation of condensation and therefore also mould.
