Graffiti Blocking

Several types of concrete masonry units (CMU or block) are available on the market. One type is a smooth-face block, a lower-quality option typically used as a backer block behind the brick facade of a building. Due to its lower quality, we recommend treating it with an elastomeric waterproofing paint. These paints come in various colors and textures to provide additional protection. Transparent waterproofing materials can also be used on smooth-face blocks, but due to their porous nature, they would need to be treated frequently, making them less cost-effective.
