How do I remove graffiti from brick, block, concrete or stone?
Diedrich offers two different paint removers that can remove graffiti without damaging the surface. The Diedrich 505 Special Coatings Stripper or the Diedrich 606 Multi-Layer Paint Remover can be used. Test samples should be conducted to determine which will be the most effective. If permanent markers have been used the Diedrich 505 will be the most effective.
