Mark Block

Mark Block is a clear, water-based sacrificial coating for control of graffiti on most building surfaces. Mark Block acts as a graffiti barrier, preventing spray paints, crayons and ink from penetrating and staining the underlying surface. Graffiti is removed from protected surfaces with high-pressure hot water (>180F.) In the most severe cases, ITD’s Mark Shark graffiti remover may be required to completely remove graffiti. Following graffiti removal, Mark Block must then be reapplied to restore the barrier. Mark Block allows for cost-effective protection of chronic graffiti without using heavy duty strippers repeatedly, risking surface damage. It does so without affecting the appearance of the surface. • Prevents Graffiti from Penetrating • Easy, Fast Graffiti Removal • Use On Any Surface • Water-Based • Dries Clear Mark Block Spec Sheet
