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 sandstone.
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 for SEMI-Guard or TEMPO-Guard.
Recommendation: to avoid possible cracking, chipping or blistering, especially in the joints areas, we recommend SEMI-Guard or TEMPO-Guard as suitable graffiti coating for sandstone.
