For public parks, roadside picnic areas, and other outdoor locations where dining accommodations are appreciated or expected, precast picnic tables are more economical than wood or metal. In addition, they can be easily cleaned of graffiti using soft-blasting materials.
One benefit of precast cement is that it is non-combustible and actually provides a great deal of endurance against fire. In addition, the use of precast concrete floors and walls provides excellent compartmentalization in multi-family or office structures.
Now what? The colorant you applied to precast concrete is peeling and blotchy. To restore the appearance, remove the failing sealer, clean and prepare the exposed surface, and carefully apply one of the new, more effective color sealants.
When setting a precast concrete seepage pit into the soil, surrounding it with stone or gravel not only improves soil stability, it also improve soil absorption. This is especially important when installing a pit with open joints.
Color can add depth to precast steps, stairs, risers, blocks, and pavers. New, cement-based coloring agents can be applied directly to both flat and textured surfaces. The compounds create deep, rich color and detail, and bond tightly to the surface for a lasting finish.
