E128AF Arctic Epoxy Mortar Concrete Patch Kit | Cold Condition -10°F to 40°F

E128AF is a three component 100% solids epoxy mortar designed for cold applications where temperatures are as low as minus 10 degrees F. (-10°F).  Recommended for cold storage areas, freezers or general cold weather indoor and outdoor patching in winter.  Designed for resurfacing from 1/8″ to 1/4″ and patching up to 2″ deep.

Packaged in an easy to use 3 part kit (18 lbs that covers 1/8 of a cubic foot or 6 sq’ @ 1/4″) and includes silica sand and the 2 part epoxy.  For larger projects available as epoxy liquid only (add your own silica sand) in 1 gallon, 3 gallon and 5 gallon 2 part kits.   If you need the silica sand, we offer 44 lbs of a 50/50 blended mix of 20-40 mesh and 40-60 mesh.  Mix 42 lbs of the blended mix with each 1 gallon of E128AF Liquid Only.

Do not apply below -10°F or when temperatures are above 40°F.  Be very careful to mix only what you need as product has a very short working time.

PRIMER: No primer is necessary.

TOPCOAT: None required. Many epoxies, polyaspartics and urethanes can be used

RODUCT STORAGE: Store product in an area so as to bring the material room temperature before using.  Continuous storage should be between 60 and 90 degree F.  Low temperatures or temperature fluctuations may cause product crystallization.

SURFACE PREPARATION: All dirt, oil, dust, foreign contaminants and laitance must be removed to assure a trouble free bond to the substrate. We recommend that an aggressive shot blast be performed prior to the application of this product.  A less adequate method would be acid etching, but the etching should properly profile the substrate. All edges and around columns or beams should be mechanically scarified. All termination points should not be feather edged, but should be saw cut with the termination ending at the sawcut. All large cracks should be V cut and filled with appropriate crack filler. All expansion joints should be filled with appropriate joint filler. When overlaying an expansion joint, a single saw cut through the epoxy overlay will prevent random fracturing.

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: It is important that the liquids be mixed together first. Mix the liquids in an oversized container thoroughly and until streak free. After the liquids are thoroughly mixed, add in the aggregate. Mix in the aggregate with slow speed mixing equipment such as a jiffy mixer or rotating bucket/stationary mixing blade assembly. It is equally important that enough time is spent mixing in the aggregate to insure that the aggregate is thoroughly wetted out. No induction time is necessary.

Improper mixing may result in product failure. This material has a high viscosity – mix well.  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.

WARNING! This product has a very short pot life, mix only an amount of material that can be used in the prescribed pot life. Work must be performed in a quick and organized manner.

PRIMING: No primer is necessary. This material is self-priming. However, any suitable primer can be used.

PRODUCT APPLICATION: Immediately after mixing, apply the mixed material at 1/8 to 1/4 inch thickness. Apply the material with a hand trowel or other suitable application equipment. Do not over-trowel the material as this may cause isolated blisters to form. Direct air
currents above or across the mortar during the curing process may cause isolated blisters. Maintain temperatures within the recommended ranges during the application and curing process.ess. Do not over-trowel the mortar as this can cause blistering. Air currents directly across or above the mortar may also cause blistering.

RECOAT OR TOPCOATING: No recoating or topcoating is necessary. However, if you opt to topcoat the applied mortar, allow it to cure before topcoating. Many epoxies and urethanes can be used. Contact your sales representative for suitable topcoat selections.

CLEANUP: Use xylol.

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 stability or gloss may be affected by environmental conditions such as high humidity or chemical exposure.
  • Colors may vary from batch to batch due to variation in the silica filler.
  • This product is not UV color stable and exposure to lighting such as sodium vapor lights may cause discolorations.
  • Substrate must be dry and free of ice with temperature 5°F above dew point.
  • All new concrete must be cured for at least 30 days prior to application.
  • Physical properties are typical values and not specifications.
