Following the tradition of treating both historic and contemporary building fabric with care and sustainability, KEIM offers graphite protection products that protect the original building fabric but do not chemically or physically impair it. The products are completely reversible. Due to these properties, they are even recommended by monument conservation authorities.
APP S is a semi-permanent, reversible protection system against graffiti and airborne contaminants, specifically designed for the protection of vertical surfaces in construction. It can be used on most wettable and porous surfaces.
