E5013 Fast Set Epoxy Primer WB 

E5013 Fast Set Epoxy Clear Primer WB is a water based 2 component epoxy penetrating clear primer coating with superb chemical resistance, abrasion resistance and substrate penetration.  Has excellent adhesion with 425 psi. When used as a primer coat for, epoxy, polyaspartic and urethane coating systems can help prevent damage (bubbles and air pockets) to the topcoat from concrete outgassing.

As a fast setting epoxy, E5013 allows application of topcoat same day and can support foot traffic in 6-12 hours.

Comes in a gloss clear finish.  The clear is not water clear and not suitable as a final topcoat over previously color coated floors.

Available in a quart kit, 1 gallon kit, 2 gallon kit and 5 gallon kit. For areas subject to constant exposure to water or high humidity, consider using our AM5015 Anti-Microbial Mildew Resistant Epoxy Primer

PRIMER: None required

TOPCOAT: Many products are suitable as topcoats including epoxy, urethane and polyaspartic coating systems.

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. For a complete system build higher than 10 mils dry, we recommend a fine brush blast (shot blast). 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. Improper mixing may result in product failure. For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer.

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. The information on the front side are reliable guidelines to follow. 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.

CLEANUP: Use PM solvent

FLOOR CLEANING: Caution! Some cleaners may affect the color of the floor installed. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested.

RESTRICTIONS: Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the floor remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.


  • Color or gloss may be affected by humidity, low temperatures, chemical exposure or sodium vapor lighting.
  • Product will yellow in the presence of UV light
  • 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
