Xmark Black Diamond Anti-skid Foam is a reusable moisture-resistant foam providing one of our highest levels of surface protection. The foam has a specially formulated coating on its base that resists shifting and moving, minimizing the need to secure it with tape. The top side is textured in a diamond pattern to provide added traction for foot traffic and channel away water from the surface when wet. This foam is ideal for surface protection where increased cushioning is needed to help protect those areas of the construction site that are more vulnerable to damage.
