Vertical Wall Epoxy Block Filler

Vertical Wall Epoxy Block Filler is a two component 100% solids high build epoxy colored coating designed for applications to vertical cement or concrete block wall surfaces without sag or runs up to 20 mils per coat at 70°F without sagging.

Comes in 1 gallon kit and 5 gallon kits.  Available in a semi-gloss with a wide selection of 11 color options.

PRIMER: Recommend E1015V

TOPCOAT: None normally needed (for increased chemical resistance and increased UV stability use an aliphatic urethane topcoat)

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 two coat thin to medium build system on vertical surfaces, we recommend mechanical scarification until a suitable profile is achieved. All dirt, foreign contaminants, oil and laitance must be removed to assure a trouble free bond to the substrate. When the vertical surface is below grade, a test should be made to determine that the concrete is dry; 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 is dry enough to start coating. The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding.

PRODUCT MIXING:  This product has a mix ratio of 8.9# part A to 1.6# part B. Standard packages are in pre-measured kits and should be mixed as supplied in the kit. We highly recommend that the kits not be broken down unless suitable weighing equipment is available. After the two parts are combined, mix well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free. After mixing, transfer the mixed material to another pail (the transfer pail) and again remix. The material in the transfer pail is now ready to be applied on the primed substrate. Improper mixing may result in product failure.

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.

Use of an improper drill mixer can result in streaking of the color because the pigment has not been thoroughly blended.  It can also create curing problems if the hardener also called activator (Part B) is not thoroughly blended with the resin (Part A) which can cause some areas on your floor to remain soft and not harden properly.  DO NOT USE A PAINT MIXER.  Many mixing problems described above can be traced back to using a paint mixer..  DO NOT HAND MIX as this approach can also result in the same problems as using a paint mixer.

PRODUCT APPLICATION: The mixed material can be applied by brush or 1/4″ or 3/8″ nap lint free epoxy professional grade 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.

RECOAT OR TOPCOATING:  If you opt to recoat this product, you must first be sure that the coating has tacked off before recoating. However, all previous coats should be deglossed to insure a trouble free bond prior to application of recoats. Always remember that colder temperatures will require more cure time for the product before recoating can commence. Before recoating, 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 recoating. Any standard type detergent cleaner can be used to remove the blush. If you plan to topcoat this product with another epoxy or urethane, always check compatibility and adhesion characteristics prior to topcoating. Multiple coats of this product are compatible.

CLEANUP: Use xylol

SURFACE 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 surface to light duty and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the surface 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 stability or gloss may be affected by environmental conditions such as high humidity, low temperatures, chemical exposure or exposure to certain types of lighting such as sodium vapor lights.
  • Colors may vary from batch to batch.  Therefore, use only product from the same batch for an entire job.
  • Apply a suitable primer before using this product when necessary.
  • This product is not UV color stable but has good resistance to color change for an epoxy product. Therefore, a topcoat is optional and dependent on the environment.
  • Light or bright colors may require a suitable primer or topcoat to achieve a satisfactory hide.
  • Test sag resistance at job sight as environmental conditions, including type of substrate, humidity or temperature may cause variable results
  • Substrate temperature must be 5°F above dew point.
  • Improper mixing may result in product failure.
  • All new concrete must be cured for at least 30 days prior to application.
  • Physical properties listed on this technical data sheet are typical values and not specifications.
