Armor Coat 969 is a 100% epoxy, chemical and wear resistant topping for concrete, wood and steel. Armorcoat 969 is a two-part liquid system to which sand or inert granules are added. The surface texture depends on the type and amount of the granules used. Thickness of the AC 969 is approximately 1/8″ to 1/4″.

Armorcoat 969 can be successfully used to:

  • Top surfaces such as trenches, warehouse floors and storage tank steps
  • Patch tank containment areas and chemical loading pads
  • Repair spalled concrete warehouses, industrial walk ways and irregular surfaces.


  • Low viscosity resin that is easily applied with a 1/4″ short nap roller. No troweling is necessary.
  • Topping cures in the presence of moisture – adheres to damp concrete.
  • Topping cures rapidly and may be used within hours, depending on temperature and humidity conditions.
  • Topping has a high impact, tensile and bond strength for concrete and steel.
  • Towmotor traffic does not damage topping.

Chemical Resistance

Armorcoat 969 resists chemical attack from caustics, salts, solvents, dilute oxidizing acids and oil. It also resists sulfuric acid up to 70% and Hydrochloric acid (HCI) up to 37%.

For 1/4″ (250 mil) Coating:

  • 1Pour the AC 969 slurry aggregate mixture onto the surface to be coated and spread to the desired thickness with a clean, short nap roller or trowel
  • 2Allow the AC 969 to set 15-20 minutes and then broadcast sand onto the surface until there are no wet spots.
  • 3Allow the resin to harden and sweep off any excess sand. The floor is now ready to use.To trowel finish the floor, wet trowel with water or solvent and trowel smooth. If a more non-skid surface is required, broadcast more sand onto the surface.
  • 4Water may be used to remove the AC 969 from trowels and other equipment, if clean-up is started before the mixture begins to set. After the AC 969 has begun to set, a solvent such as methyl ethyl ketone, xylol or methylene chloride may be used for clean-up.
  • 5Smooth surface – flood coat with AC 969 A & B resin and cure only.

For 1/8″ (125 mil) Coating:

  • 1Pour the AC 969 Resin (Part A) into a clean, dry mixing container.
  • 2Add AC 969 Cure (Part B) to Resin (Part A) in the proportions of 5 parts A to 1 part B by volume.
  • 3Stir with a wooden stirring stick (4’x 1 ” x 2″) for at least 3 minutes or stir with a low speed (200-300rpm) power mixer for at least 2 minutes.
  • 4Roll coating onto surface using a long nap roller.
  • 5Broadcast sand (approximately 1 pound/sq.ft.) or inert granules into the resin until there are no wet spots.
  • 6Allow the coating to cure, then sweep or blow off excess sand.
  • 7A top coat is recommended, but optional.
  • 8Water maybe used to remove the AC 969 from trowels and other equipment, if clean-up is started before the mixture begins to set. After the AC 969 has begun to set, a solvent such as methyl ethyl ketone, xylol or methylene chloride may be used for clean-up.


Do not use AC 969 resin without sand aggregate when grouting areas deeper than 1/4″.


Armorcoat 969 is a four-component system that is available in premeasured units of 1.2-gallon (20sq.ft. kits) and 6-gallon (100 sq. ft. kits).

Coverage and Estimating

Recommended coverage for the catalyzed AC 969 on smooth surfaces, at a coating thickness of 1/8 in. to 3/16 in. is:

36 sq. ft. per gallon for two coats
30 sq. ft. per gallon for three coats
125-150 sq. ft. per gallon for the Top coat (optional).

One (1) lb. of aggregate per sq. ft. is recommended. Recommended coverage is reduced for irregular or badly spalled surfaces.

3/16 4 122-133 175

3/8 10 311-322 370

Sand aggregate is optional. Premeasured sand quantities may be purchased as a unit. It is recommended that kiln dried or bagged sand (sandblast sand) be used. Finer mesh sand may dry the mixture more than larger mesh sand. Larger grit aggregate provides a more non-skid texture.

As the ambient temperature increases, the resin will absorb more broadcast sand (part D). When ordering a complete unit (with aggregate) the packaging includes the maximum amount of part D that would be needed at 100 °F.
