Product Information

Armor-Hard is an early set, structural epoxy mortar kit designed to repair concrete floors. This kit includes a two-component structural epoxy binder and a pre-measured bag of custom-blended sand aggregate.


When the epoxy and aggregate are combined, they produce a mortar that is easily worked and troweled. It has very low odor once blended.


Armor-Hard is designed for use on industrial floors subject to hard wheeled traffic. This product provides excellent abrasion resistance and superior impact, wear, and chemical resistance.


Floors can be reopened to pedestrian/construction traffic in 3-4 hours. Grinding and sanding may begin 3-4 hours after installation. Floors at 70°F can be reopened to hard wheeled traffic in 8 hours or less.



  • This product should not be used in joints or cracks that move
  • For deep repairs, install in 1" lifts to avoid shrinkage due to exotherm
  • Not for use as a surface coating
  • Should be installed at 50°F (10°C) or higher


USDA/FDA/LEED acceptable


Note: This product is for industrial use only. Use only in well-ventilated areas. Practice all normal job site safety precautions (clear work area, etc). Thoroughly read MSDS and installation instructions for additional information prior to using material.

Surface Preparation

All surfaces must be clean, dry, structurally sound and free of grease, oil, coatings, sealers, paint, etc. Surface preparation may be accomplished by grinding, sawing, chipping, sandblasting, etc. Prevent featheredging by creating a vertical edge at outer point of defect to be repaired (1/2" minimum, 3/4" preferred). See Metzger/ McGuire's Guide to Basic Floor Repair and related information on repair procedures for recommendations. New concrete should have minimum cure of 30 days.


(Read product container labels and MSDS before using) Caution–Due to 4:1 ratio, the entire contents of both epoxy parts should be used. If using less than full unit, "A" and "B" ratio must be measured precisely by volumetric comparison.

Ambient temperature should be at least 50˚F (10˚C). Combine parts "A" and "B" in a plastic pail and mix for 2-3 minutes using a Jiffy-type mixer and a variable speed drill. Keep drill speed below 800 rpm to avoid air entrapment. If using as a liquid, dispense promptly. Application of mixed liquid as a primer coat (brushapplied) will enhance mortar adhesion.

Mortar mixing is best achieved using a 1/2" heavy duty drill with a mortar mixing paddle or a rotating pail mixer. Thoroughly mix epoxy liquid, then gradually add sand aggregate from kit until all sand aggregate is "wetted" with the epoxy.

Mix for an additional 2-3 minutes after optimum aggregate loading.


Promptly install mortar into defect, spread evenly using clean steel trowel. Finish installing each unit before mixing the next. Trowel mortar to desired density and finish texture. If mortar starts to stiffen and creates trowel drag, wipe trowel with isopropyl alcohol or acetone. The final surface density and appearance will reflect trowel pressure and intensity. Working time for mortar is approximately 30-40 minutes at 70˚F.


Spills of unmixed components can be cleaned up with solvent (Toluol, Xylol, MEK , denatured alcohol, etc). Clean tools and spills before epoxy or mortar has set using solvent or warms soapy water.
