This project took place at Audi of West Chester. The Audi project was 24,000 square feet of 5,000 psi concrete. Watch the timelapse video of the project below & learn more about the project.
Here’s the process we followed for this job:
- We routed and cleaned all control joints and coated with the vapor block then filled with a grey two-component polyurea.
- Then we shotblasted the concrete to a CSP 3-4. All holes and cracks were filled afterwards.
- Moisture tests were done, both a calcium chloride and Wagner insitu test, which showed moisture content up around 95%. Tests were installed per ASTM F2170 by W.T. Rupnicki Certified concrete slab moisture testing ID 01303981 ICRI.
- We decided to install a moisture vapor barrier supplied by CFI. This was applied at a rate of 12 mils dft. This was applied to minimize any vapor transmission through the concrete.
- After this cured, we applied the first lift of Grey 440 epoxy and broadcasted a small grain sand until rejection.
- After curing we cleaned up all excess sand and vacuumed the floor surface. Then we ran a buffer with 80grit sandpaper over the entire floor to remove any high spots.
- We then applied the second lift of grey 440 epoxy and broadcasted until rejection.
- After curing we cleaned up all excess sand and vacuumed the floor surface; then we ran a buffer with 80grit sandpaper over the entire floor to remove any high spots.
- We then applied CFI’s Wearcoat 100 as a grout and top coat to the open sand texture.
- The last task was filling expansion joints with a flexible two-component Urethane.
The project turned out beautiful and the owner is very happy with the results.
