Novolac Epoxy on Service Bay Floor in Camp Hill, PA

Day One (Surface Prep)

On the first day of this coatings project, the concrete surface was prepared. This process involved mechanically diamond grinding the concrete with two walk-behind machines for the larger areas of concrete. In the places where the machine couldn't reach (such as edges, corners, or beneath tables), hand grinders were used.

In some of the rooms, the floor was tiled. Special tools were used to rip the tiles off, exposing the concrete (and some of the old floor paint) for preparation. The pictures below are in order during the first day.

Day Two (Repairs and Primer)

On the second day, the team vacuumed any remaining concrete dust from the previous day's surface prep. Once the dust was removed, epoxy crack fillers were put into cracks to repair the concrete surface. After filling in the cracks, the team applied a primer base coat of solid color epoxy. Brushes were used for edges and beneath tables. The first picture shows the results of day one's work.

Day Three (Repairs, Second Coat, and Sand)

On the third day, any remaining cracks or surface imperfections were filled with fast-setting epoxy. Once the surface was repaired, a second coat of medium gray epoxy was applied over the primer. Sand was then broadcasted over the "wet" coating until it was completely saturated (not pictured). The addition of sand in this coating system increases the build (thickness) & compressive strength of the system.

Day Four (Novolac Epoxy)

On the final day, the team first removed any sand that did not bond with the coating. Novolac epoxy was then applied over top of the prior coatings and the sand.
