UTN60 3 gal. Clear High Gloss 2-Part Concrete and Garage Floor Coating with Oil, Gas and Scratch Resistance

The UTN60 should only be applied to diamond ground(prepped) concrete surfaces. It has the viscosity of a thin maple syrup and will not fix grout cracks (it's self leveling).

The UTN60 coating requires a concrete surface profile of 2 (CSP2). A CSP2 is obtained by diamond grinding a concrete slab with 20 to 60 grit diamond pads. Acid etching the concrete will only achieve a concrete surface profile of 1 (CSP1) which is better than no prep at all but still inferior to a CSP2 diamond grind. This equipment can be rented from companies such as Sunbelt Tool Rentals or even Home Depot.

No, this is not UV resistant.

The UTN60 can be applied over unsealed/acid stained surfaces.

The UTN60 can be applied over a two part epoxy but the existing epoxy coat will need to be scuffed with an 80 grit screen or sand pad mounted to a floor maintainer. Make sure to wipe dust up with a tac cloth (could be a rag or mop dampened with acetone). Now that the epoxy is out of its recoat window these micro scratches will allow a new epoxy or urethane coat to bond. The UTN60 is applied thin and is not an appropriate base product for broadcasting flakes. A thicker high solids epoxy base is superior for broadcasting flakes. The UTN60 does make a great clear coat over epoxy with flakes.

Foundation Armor does not recommend applying the UTN60 to Terrazzo. It's recommended for concrete surfaces or as a top coat for compatible epoxy coatings (within the epoxy recoat window or 80 grit screen scuffed epoxy if outside of the recoat window).

The UTN60 has been successfully applied over one part epoxy paints before. However, it appears that your one part epoxy paint does not have a good bond with the concrete which is causing it to delaminate from wheel traffic. You may want to consider renting a diamond grinder to remove the old product and prep the surface by opening up the concrete pores. The real concern is not the UTN60 delaminating from the epoxy but the epoxy delaminating from the concrete and taking the UTN60 with it.

You can apply a clear coat of UTN60 over an epoxy system. The UTN60 is very durable, more chemical resistant than epoxy and will not yellow. You need to make sure the UTN60 is applied within the recoat window of your epoxy so that it bonds correctly. Usually 4 to 6 hours is typical for a solvent epoxy recoat window. If the UTN60 is used as a stand alone product, you would put one coat down and then go back 10 to 12 hours later for the 2nd coat(a longer recoat window than epoxy but worth the wait). If the slab has slight dampness, you could also use the Armor Epoxy sold on homedepot.com prior to your higher solids epoxy coating and the UTN60.

Each UTN60 kit has 3 single gallon bottles Two of the bottles are Part A and one bottle is Part B (catalyst). The mix ratio is two parts A to one part B. You can either mix the whole kit in a 5 gallon bucket and slow drill mix or perform a partial mix which is ideal when a person is working solo(basically pour one gallon of part A into a bucket and then measure out 1/2 gallon of part B). Once you mix the material, plan on a pot life of about 30 min. Best to roll on the product with a low nap roller 3/8 inch shedless which can be purchased at any Home Depot store. Use a metal or PVC tray (no cheap tray liners because the solvent will eat though low grade plastics). This product is applied thin, plan on a 3 gallon kit covering around 800 square feet for a base coat or 1000 square feet for a top coat.
