Water Based Urethane Gloss

SURFACE PREPARATION: For a thin film build system (2-3 mils) we suggest either mechanical scarification, acid etching (and then neutralize to 7 PH), or diamond grinding until an appropriate profile is accomplished. To ensure adequate adhesion, the substrate must be free of all dirt, oil, dust, and foreign contaminants. Prior to application, a test should be made to determine that the concrete has an acceptable vapor barrier. This can be done by placing a 4’ X 4’ plastic sheet on the substrate and completely taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate does not show signs of eventual hydrostatic pressure problems that may later cause loss of adhesion. Adhesion tests are recommended prior to using.

PRODUCT MIXING: Pour a full pre-packaged kit of 4 parts of Part A to 1 part of Part B together and mix well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and homogenous. Water Based two part systems need to be mixed well for an adequate cure and a streak-free finish.

PRODUCT APPLICATION: Apply the mixed material by brush or roller to a primed surface with a 3/8” nap shedless roller cover at a rate of 200-350 sqft per gallon within the usable pot life time frame, as well as the recommended temperature and relative humidity guidelines listed in the Technical Information section. If continuous outgassing in the concrete is causing bubbles, re-roll the material using a cross rolling method before the material cures to reduce or eliminate air entrapment. If the material becomes thick while applying and 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! Remove any excess material in joints or low impressioned areas. Puddled areas may not cure adequately and may cause blush or a white haze. If recoating after 18 hours (temperature depending) a light sanding using a fine sanding screen may be needed to ensure adequate inner coat adhesion.

PLEASE NOTE: Applying WB Urethane Gloss outside of the suggested parameters may result in job 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.
