E105M Epoxy Chemical Resistant

E105M is a three component 100% solids epoxy mortar designed for patching or resurfacing concrete floor applications where excellent wear characteristics are required.  Recommended for resurfacing and repair of concrete floors, walkways, loading docks, seamless floors and general patching.  Designed for resurfacing from 1/8″ to 1/4″ and patching up to 2″ deep.

The E105M floor systems is extremely durable, resistant to wear and tear, and can withstand a wide range of chemicals.  The E105M is typically used to resurface older, damaged concrete Mortar products offer higher impact resistance and greater compressive strength than concrete. These floor systems are extremely durable, resistant to wear and tear, and can withstand a wide range of chemicals.

The E105M is available in 5 colors: light gray, dark gray, tile red, black natural and comes packaged in 4 sizes which includes liquid Parts A and B plus aggregate.  1 unit (0.40 cubic feet) of E105M has a coverage rate of 19.15 sq’ @1/4″ and 38.3 sq’ @1/8″ and comes with 4.7 lbs Part A, 2.3 lbs Part B and 50 lbs of aggregate. E105M also is available 1/4 units (0.10 cubic feet), .1/2 units (0.20 cubic feet) and a bulk (5) unit size (2.0 cubic feet)

Application temperature range 55°F to 90°F

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

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

RODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using.  Continuous storage should be above 55° F to prevent 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.

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

PRODUCT APPLICATION: Apply the mixed material at 1/8 to 1/4 inch thickness. Apply the material with a hand trowel or other suitable application equipment. Maintain temperatures within the recommended ranges during the application and curing process. 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, low temperature or chemical exposure.
  • Colors may vary from batch to batch. Therefore, use only product from the same batch for an entire job.
  • This product is not UV color stable and exposure to lighting such as sodium vapor lights may cause discolorations.
  • For chemical exposure areas, we recommend a suitable topcoat to reduce porosity and chemical migration.
  • Substrate temperature must be 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.
