Norklad WB is a two component water based epoxy coating. Low odor, no flammability and excellent adhesion combined with a long lasting finish is why waterborne epoxy dominates the do-it-yourself market. This high gloss epoxy color coat formulated for excellent hide as well as abrasion resistance. Norklad WB is compatible with high performance topcoats; urethanes, epoxies, or 100% solids.
This product has Low VOC and suitable for a variety of applications such as wood, masonry or previous coated surfaces. Steel and vinyl tile can also be coated when primed correctly. This product can withstand exposure to many common solvents and chemicals.

* For best results use a 1/4” or 3/8” nap roller.
* Slab on grade requires moisture barrier
* Substrate temperature must be 5°F above dew point.
* All new concrete must be cured for at least 30 days
* Improper mixing or too thick of an application may result in product failure
* Light or bright colors (white, light gray, etc.) may require multiple coats achieve a satisfactory hide, depending on the porosity of the substrate.
SURFACES: New Surfaces: Concrete, Plaster and Masonry - Cure at least 30 days before painting. pH must be 10.0 or lower. Remove laitance and roughen unusually slick poured or precast concrete by acid etching, sandsweeping, grinding, or shot-blasting the floor. If substrate has been washed allow to dry overnight. Remove loose aggregate. Fill voids and cracks in areas of concrete with epoxy filler or patching compound. In moisture prone areas, prime with this product or substitute to achieve best penetration. Drywall - Prime with this product or suitable waterborne primer. Wood - Prime with this product or prime with suitable waterborne epoxy primer. Steel - Prime with waterborne epoxy primer or preprime epoxy. Galvanized Metal and Aluminum - Prime with waterborne epoxy primer . Glazed Brick, Ceramic Tile and Fiberglass - Scuff sand and prime with waterborne epoxy primer. Previously Painted Surfaces: The waterborne components of this product generally allow use over most old coatings. Old coatings should be tested for lifting. If they lift, remove them by chemical or mechanical means. Wash to remove contaminants. Rinse thoroughly and allow to dry. Dull glossy areas by light sanding. Remove sanding dust. Remove loose paint. Mix and begin painting.
PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 60 and 90 degree F. Keep from freezing.
SURFACE PREPARATION: Surface preparation will vary according to the type of complete system to be applied. For a one or two coat thin build system (3-10 mils dry) we recommend either mechanical scarification or acid etching until a suitable profile is achieved. All dirt, oil, dust, foreign contaminants and laitance must be removed to assure a trouble free bond to the substrate. A test should be made to determine that the concrete has an appropriate vapor barrier. This can be done by placing a 4’X4’ plastic sheet on the substrate and 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 disbanding. However, this product can be applied to a damp floor as long as there are not standing puddles.
PRODUCT MIXING: This product comes pre-packaged by weight. Kits should be mixed in their entirety. If partial kits are to be used, refer to the front of this technical data for proper weight mix ratios. After the two parts are combined, mixes well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free. This product is an emulsion product and should be mixed well before using.
PRODUCT APPLICATION: The mixed material can be applied by brush or roller. Maintain temperatures within the recommended ranges during the application and curing process. Apply material with relative humidity within the parameters shown on the technical data. When the end of the pot life has been reached, you will find that the material becomes hard to apply and will actually tend to roll back up onto the roller. Do not try to continue application when the coating has reached this step. Applications made at different times with differing environmental conditions, may show slight variations in gloss.
RECOAT OR TOPCOATING: If you opt to recoat or topcoat this product, you must first be sure that all of the solvents and water have evaporated from the coating during the curing process. Within 7-10 hours it should be ready for your subsequent coat. However, it is best to test the coating before recoating or topcoating. This can be done by pressing on the coating with your thumb to verify that no fingerprint impression is left. If no impression is created, then the recoat or topcoat can be started. Always remember that colder temperatures will require more cure time for the product before recoating or topcoating can commence. Before recoating or topcoating, check the coating to insure no epoxy blushes were developed (a whitish, greasy film or deglossing). If a blush is present, it must be removed prior to topcoating or recoating. A standard type detergent cleaner can be used to remove any blush. Many epoxy overlays and coatings as well as urethanes are compatible for use as a topcoat for this product as well as multiple coats of this product.
