MCI® Wall Defense is a clear, silicone elastomer-based anti-graffiti coating that can be applied to exterior concrete, masonry or metal surfaces. It is designed to be used over various types of surfaces that are coated or uncoated. This permanent coating does not need to be reapplied after graffiti removal like alternative sacrificial systems. However, MCI Wall Defense can be recoated over itself, while other coatings, tagging or graffiti will not stick. MCI Wall Defense resistance starts to work 24 hours after coating.
The coating offers excellent exterior durability and is breathable and VOC compliant.
Features include high UV resistance, excellent gloss retention, elastomeric properties and hydrophobicity.
The coating may be applied by spray, brush or roller. A film thickness of 12-15 dry mils (300-375 microns) is recommended. The coating dries to touch in two hours. Any tagging is removed with a cold water pressure cleaning of ~ 1200 psi; no special cleaning agents are needed.
