"They did great work. I asked Mike to submit an estimate to my email so I could send it to my home owners insurance, which he did the same day. I also appreciated that they took care to keep the area being worked on contained from the rest of the room. No clean up or dust created by them. I will definitely use them again."

"The craftsmanship is incredible. The pattern is cobblestone and visitors believe it is real stone. There were a couple minor issues, including 4 feet wide instead of 3 in one area and a delay in getting our stairs attached. The crew is fantastic and very professional."

Epoxy Flooring FAQs, answered by experts

Sealing a concrete surface protects it from damage caused by water, chemicals, and general wear and tear, making it last longer. A good sealer acts like a shield to prevent cracks, stains, and deterioration. Plus, it enhances the appearance of the concrete, giving it a fresh, polished look that can boost your property’s curb appeal.

Yes. So-called “floating” cork floors can be installed over concrete subfloor, though a polyethylene vapor barrier is required. This type of installation is achieved using the glue-down tiles, which are trickier for a DIY approach, so consider calling a professional to help you if you’re planning to install your cork floor over concrete. 

You can whiten concrete for unsealed and unfinished concrete with a solution or either muriatic acid or bleach and water—but never both. However, if your concrete does have a stain, finish, or polish, keep in mind that these hard chemicals could damage the topcoat. Your best bet otherwise is to power wash outdoor concrete slabs or clean indoor ones with a gentle cleaner such as laundry or dish detergent.

Exterior paint finishes come in a variety of options, but for concrete, your best bet is to go with an eggshell, satin, or semi-gloss latex paint. All three options are more durable than matte finishes and should help hide imperfections on your home’s concrete surface.

Yes, it is possible to apply a concrete coating yourself, especially for smaller applications if you have the proper equipment. However, for larger projects, a professional application is recommended to ensure durability, slip resistance, and proper adhesion.
