Concrete floors in industrial environments are typically subject to extreme traffic from heavy wheeled carts and machinery.
Armor-Hard Extreme is a 100% solids, two-component, low-odor, fast-set structural epoxy/epoxy mortar kit intended for use in the structural repair or joints, cracks, and other surface defects in industrial concrete floors. Armor-Hard Extreme provides superior impact and wear resistance.
Armor-Hard Extreme’s fast-set chemistry allows for quick return to service. Treated floors are ready for foot traffic in one (1) hour and normal in as little as two (2) hours.
Armor-Hard Extreme can be installed in temperatures as low as 20ºF (-7ºC) to as high as +120˚F (49˚C), giving this product a wider application range than competing structural epoxies.
This kit includes a specially engineered aggregate blend designed for easy troweling/finishing.
- This product should not be used in active or moving joints unless a relief joint is formed or saw cut
- For deep repairs at warm temperatures, install in max. 1" layers to avoid shrinkage due to exotherm

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 feather edging by creating a vertical edge (1/2" minimum, 3/4" preferred) at outer point of defect to be repaired.
Due to 5:1 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.
For fastest cure time, material should be stored and mixed at ambient temperature (i.e. 70˚F). Warmer material temperature will lead to reduced pot life, cooler temperatures will lead to longer working time (and slower cure time). Combine parts "A" and "B" in a plastic pail and mix for 1.5 minutes using a Jiffy-type mixer and a slow speed drill. If using as a liquid, dispense promptly due to short pot life. If using as a mortar, application of mixed liquid as a primer coat (brush) 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 aggregate. Continue to add aggregate until mixture appears slightly dry, but all aggregate is "wetted "with the epoxy. Mix for an additional 1-2 minutes.
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 solvent such as denatured alcohol, toulene, xylene or MEK. The final material density and appearance will reflect trowel pressure and intensity. Working time for mortar is approximately12 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 warm soapy water.
