Surface Preparation and Repair
No matter what coating system we are using, it is extremely important that the concrete surface is free from defects that cause poor product adhesion and early system failures. These defects include cracking, spalling and pitting in the concrete substrate all of which must be repaired prior to installation. For this reason Kelly Construction uses a combination of shot-blasting and diamond grinding to properly profile the surface to ensure our quality products perform at the maximum no matter the size of the work.
Kelly Construction is among the Quad Cities premier concrete repair companies. Inside or outside, residential commercial or industrial, our concrete repair contractors have brought new life in for many spaces.

Benefits to a poly chip floor:
- Polyurea coatings are extremely flexible, in fact are 98% more flexible than typical Epoxy/Hybrid floor coatings. This flexibility is key during the summer to winter transition when the ground and concrete are freezing. During this time, the concrete is shifting and expanding which causes most floor coatings to fracture and crack. Polyureas, being as flexible as they are, expand and contract with the concrete leaving the surface strong and intact. Polyureas are also fully cured after 24 hrs. This does not allow the product to get harder or softer over time and with different temperatures. Epoxy/Hybrid floor coatings cure to 80% in 7 days and over the course of time cure the additional 20%. During this time the product continues to get harder and more brittle causing epoxies to eventually fracture and crack causing delamination.
- Polyureas are 4 X more abrasion resistant than epoxy/hybrid floor coatings. This is due to their extreme flexibility, elongation, dense cross-linking, and mar resistance. Polyureas can take a tremendous amount of abuse because they are malleable and can take the physical impacts and disperse them, much like the rubber on a car tire.
- As well as being flexible and abrasion resistant, polyureas are more chemically resistant to a much wider range of chemicals than epoxy surfaces. This is due to their densely cross-linked chemistry. From Salt, Oil, Gas, and Grease, to Acids, Skydrol, and Hydroxides Polyureas will withstand a wide range of chemicals including salt, oil, gas, grease, skydrol and acids that you may use in your garage.
- Polyureas have 2 X the adhesion over typical epoxy/hybrid floor coatings. Polyureas are commonly associated with spray on liners in pickup trucks. Polyureas are made from the same materials only reformulated for concrete. In a spray application, the product is cured within 17 seconds and has an eternal bond to the substrate. This same chemistry is used in our floor coating product but slowed down to an hour cure time. This gives the product time to penetrate into the concrete deeply and bond molecularly into the concrete.
- Polyureas are 100% UV stable. UV stability is very important if you want your finish to look great and last! You will never see a difference in color with areas that are exposed to UV rays. These areas could include windows, doors, garage doors, and the portion of the floor that sticks beyond the garage door and is exposed to light every day! The UV stability of our product is backed by a written lifetime warranty!
