Mark Block

Description

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.

Do not dilute – use as is. Ensure surface is clean and dry. Apply to surface using a low pressure pump-up sprayer or airless sprayer. Use wide spray pattern. Product may also be applied with a brush or roller. Usage rate depends on surface porosity and can range from 100-400 square feet per gallon. Some highly porous surfaces may require up to 4 coats for full protection, but 1-2 full coats will suffice for most surfaces.
