740 EP Mortar 25 Patch
722 HB FS Epoxy is a two component 100% (+/- 1%) solids colored epoxy coating designed for applications where a high build impact and chemical resistant floor is needed. 722 HB FS Epoxy has good low temperature cure capabilities down to as low as 45°F. However, this product only has fair color stability and should be top coated with an aliphatic urethane when long term color stability is a requirement.
Color stability may be affected by environmental conditions (high humidity or chemical exposure). This product is not UV color stable and may discolor if exposed to lighting such as sodium vapor lights.

Colors may vary from batch to batch due to variations in the silica filler. Mortar colors are not from our standard color chart. Substrate temperature must be 5°F above dew point. All new concrete must be cured for at least 30 days prior to application. See reverse side for application instructions. Test data based on neat resin.
Physical properties are typical values and not specifications.

See last page for limitations of our liability and warranty. This product has a short pot life, mix only an among of material that can be used in the prescribed pot life period. When temperatures are low, extended time may be required for the material to cure before allowing industrial traffic.

Product Storage:

Store product in an area 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 etch 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 saw cut. All large cracks should be V cut and filled with an appropriate crack filler. All expansion joints should be filled with an appropriate joint filler. When overlaying a 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 ensure that the aggregate is thoroughly wetted out. No induction time is necessary. Mix only an amount of material that can be used in the prescribed pot life period. Improper mixing may result in product failure.


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 ¼ 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 currrents across or above the mortar during the curing process may result in isolated blisters. Maintain temperatures within the recommended ranges during the application and curing process.

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 (temperature permitting). Contact your sales representatives for suitable topcoat selections.


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.


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.
