On a surface coated with Geotect’s Geoclear, virtually nothing can adhere either oil-based or water-based.
You don’t have to paint walls over and over to cover up graffiti if those are coated with Geoclear. It’s difficult to compose drawing with lacquer or paint sprays and easy to clean up, so it also has a psychological effect to prevent vandalism.
Also, with its self-cleaning function, it’s very effective for road signs and board signs to keep them clean and visible.
