Surface Preparation: Surface preparation is key to the success and life of the UTN60. UTN60 must be applied to fully cured unsealed interior concrete that has been properly prepped with a diamond grinder to a 25-80 grit finish (concrete surface profile 3). Surface needs to be completely dry and free of oil, dirt, grime, wax, detergent or any incompatible paint or coating. If applying the Armor UTN60 as a top coat over the Armor Epoxy Primer, UTN60 must be applied within the recoat window of the Armor Epoxy. If applying the UTN60 to an existing coating, it is important to first speak with a Foundation Armor Technician regarding compatibility, required surface preparation and application.
Product Mixing: Clear UTN60: Slow drill mix 2 Parts A with 1 Part B in a clean 5 gallon pail. Mix for 60-90 seconds, or until material is thoroughly blended and homogenous. Avoid whipping air into the coating. Improper mixing can result in coating failure.
UTN60 w/Color Pack: Before adding in Part B, slow drill mix color into pre-mixed Part A for roughly 30 seconds. 4.5-6 oz. of color should be added to each gallon of material. For example, if you are mixing a 3 gallon UTN60 kit, you would mix in a total of 13.5-18 oz of color. Once the color has been mixed into Part A, add in Part B and slow drill mix for 60-90 seconds, or until material is thoroughly blended and homogenous. When applying the UTN60 in a color, you may see small areas of concrete through the first coat of material. Applying a second color coat will help to achieve a consistent opaque surface finish.
Non-Slip Additive: For added surface traction, the Armor Non-Slip additive can be added. The ultra-fine, fine, and coarse Armor Non-Slip additives works best in the Armor UTX60. Applying the Ultra-Fine: Slowly drill mix 3-6.5 ounces of non-slip additive per gallon, until completely blended, then apply. For Fine and Coarse: When applying the second coat, add the non-slip additive to the coating using a broadcast spreader, and back roll to encapsulate the non-slip additive.
DuraTrac Additive: Slowly drill mix the DuraTrac additive into the fully mixed, ready to apply UTN60. If applying in color, ensure the color has been mixed in as well. While 5 ounces of DuraTrac per gallon of UTN60 is suggested, you can add up to 32 ounces of DuraTrac for every 1 gallon of UTN60. Please note, the more DuraTrac you add, the more cautious you need to be to avoid clumping. If clumping occurs, too much DuraTrac has been added. DuraTrac can also slightly reduce the gloss level. Testing in a small area is strongly suggested in order to determine the appropriate amount of DuraTrac necessary for your application.
Please note, do not apply both the Armor Non-Slip Additive and the DuraTrac Additive. Only one should be applied per application.
Product Application: Apply the mixed material using a 3/8” shed-less nap roller. It is important to apply within estimated pot life and recommended temperature guidelines. Please note that pot life may vary. If the material becomes thick while applying, or starts sticking to the roller , stop applying and discard the mixed material. At this point it has reached the end of the usable pot life. While applying keep a wet edge to prevent roller marks. It is recommended to work in sections usually using control joints as dividers to ensure proper application results. Do not allow to Puddle! If recoating after 24 hours you must wait 5-7 days to allow the coating to cure. Once 5-7 days has passed, a light sanding using an 80 grit screen pad (and a thorough surface cleaning) is required prior to applying an additional coat to ensure adequate coat adhesion.
Blending roller lines: When rolling the UTN60 it is considered a best practice to lift the roller at the end of the stroke so there are no roller lines/stop lines. Applying the UTN60 is very similar to applying paint, be sure to always maintain a wet edge. Work fast, but controlled, you only have about 25-30 minutes of working time before the pot life is reached.
Applying UTN60 outside of the suggested parameters may result in application failure. It is always recommended to test the product in a small, inconspicuous area (on the same concrete substrate) for desired results prior to application. Coverage rates may vary for all coatings and substrates depending on porosity, density, texture etc. The applicator is responsible for suitability of application, and the results of the application. We suggest applying to a test area first to verify compatibility, absorption, coverage rate, and project suitability.
Clean-Up: Use MEK. Dispose of containers in accordance with local and federal regulations. Product-Removal: Dried, cured sealer may be removed with the Armor CR100, or by using a diamond grinding method, sandblasting method or similar mechanical action.
