Diamond grinding prepares the concrete for coating. It removes rough spots, contaminants, and older coatings. It does not generate hazardous waste or damage the concrete and creates a perfect surface for coating. When performed properly, diamond grinding is the least damaging preparation method for your concrete and the ideal prep solution for epoxy floors.



Shotblasting is used when a floor is in need of major repairs and resurfacing. With a process that involves throwing steel shot directly on the concrete floor, concrete shot blasting mimics sand blasting in order to level off the floor, remove stains, and remove markings. The process leaves aggressive profiles which allows for floors that are 1/8” or thicker to bond properly to the concrete surface.

Reduced Install Cost Concrete Polishing


Hand grinding is a crucial step to insure a proper bond of the epoxy all the way to the available edge. Failing to prep as close to the edge as possible can lead to coating failure. Detail work, that if overlooked, could cost you later.



After epoxy floors are in place, proper sanding is important. When performed correctly, sanding creates a stronger mechanical bond between the epoxy and urethane top coat – producing longer lasting results with greater durability and improving aesthetics.

cleaning concrete floors


Once the grinding is complete, a thorough cleaning of the surface is required to ensure the concrete coating adheres properly. This begins with an in-depth scrubbing to remove all major dirt, grit, and debris.

Vacuuming industrial concrete floor


Nothing can sabotage a floor resurfacing project as easily as dirt, grit, and other debris. It is essential that floors are vacuumed properly to insure maximum adhesion and improved aesthetics. Using HEPA filters helps reduce dust and particles from the air and keep the surface as clean as possible.

Caulking joints polished concrete


Effective caulking protects the sidewalls of the joints to keep them from deteriorating. Additionally, joints that have not been caulked allow dirt and debris to get trapped – making them more difficult to clean. Cleaning and caulking joints is an important step to protect joints and give cleaned and coated floors a finished look.
