GCR 3
Clear Top Coat
Product Description
GCR 3 Clear Top Coat is a non-immersible, high performance, zero VOC, aliphatic polyurethane that provides a continuous high or low gloss finish, whereby eliminating the need to strip, wax and buff floors with heavy machines and harsh chemicals. GCR 3 has high wear resistance and can be easily maintained through normal good housekeeping procedures with a damp mop. It can also be recoated or repaired when needed. For damaged, worn or mismatched floors, GCR 3 can be applied over the GCR 2 Epoxy Base Coat to create a new seamless floor with optional decorative broadcast media.

Theoretical Coverage Rates
Spread rate is dependent on application method, substrate and anticipated level of use. Below figures are estimates. Testing should be completed for accurate figures. Application loss factor is not covered due to surface profile, porosity, surface irregularities, application technique, spillage, film build or climatic conditions. Coverage rates below are per 1 Unit Kit (Note: 4 Unit Kit will yield 4 times the coverage):
| Surface | Ft2 / Unit Kit | Ft2 / Repair Kit | # Coats |
|---|---|---|---|
| VCT/VAT | 350 | 10-15 sm / 80-85 lg | 1-2 |
| Rubber | 350 | 10-15 sm / 80-85 lg | 1-2 |
