Graffiti can be removed from basically all types of surfaces. It is important to choose the appropriate graffiti remover or graffiti protection for the substrate.
Following products are recommended for graffiti removal and graffiti protection from thermal insulation system.
Hint: PERMA-Primer is used in combination with PERMA-Guard to enhance its adhesion or for strong color changes. The substrate darkens only slightly or not at all. No need to prime with PERMA-Primer for acryl based new surfaces.
PERMA-Primer – No need for a primer if the surface has been treated with an acryl based facade paint.
Examples of acryl based facade paints are:
Sto Color - Maxicryl
Brillux Evocryl 200
Caparol Acryl-facade white
If you don’t know the type of facade paint or if it isn’t an acryl based facade paint we recommend using PERMA-Primer. CAUTION!! Do not use graffiti protection (PERMA-Guard) on facade paints with lotus effect or strong hydrophobic properties or on facades/ facade paints that have been subsequently impregnated.
Hint: The removal of graffiti from painted or lacquered surfaces leads, due to the special solvents used, to the removal not only of the graffiti but also of the facade paint/varnish. As a result the affected area needs to be painted/varnished again.
Recommendation: Due to insufficient breathability of the facade, bleed-through of painted over graffiti and poor adhesion (spray paint) through graffiti, it is necessary to always remove graffiti before painting over.
