Surface preparation is a necessary part of decorative concrete product application. Special care must be made to ensure the proper surface conditions for water-based stains, acid stains, sealers, overlays, topical coloring products, and anything applied to the surface of existing concrete. Without proper surface preparation, failure is all but guaranteed. While it may never be visible in the finished product, good surface preparation is key. Avoid call backs and refunds by taking the time to properly prepare the concrete surface before a project.
