Epoxy.com Product #27

Slow Setting Mortar Pack


Epoxy.com Product #27 Grout/Mortar Pack is a preproportioned 100% solids epoxy resin pack and a blend of special aggregate. The pot life of Product #27 is 3 times longer than ordinary epoxy packs; while curing the entire pack, a low exotherm is produced.


  • Premeasured to avoid waste while mixing and placing.
  • Moisture insensitive before and after cure.
  • Pourable viscosity - flows easily, self levels in forms.
  • Low heat build-up - low exothermic heat development permits placement up to 10 inches thick.
  • High ultimate compressive strength
  • High ultimate Modulus of Elasticity - 2.7 X 106 psi
  • No curling or shearing away from substrate (concrete, steel or wood).


Use in areas where long pot life and extended working time are required due to higher than normal temperatures or when placement of an epoxy grout is slow.

Pot Life: 70�F (21�C)

1 hr. 45 min.

Pot Life: 102�F (39�C)

1 hr. 15 min.

Electrical Properties
   Volume Resistivity
      ASTM D-257

3.03 X 1012 ohm-cm


Pour Component 'A' into Component 'B'. Mix 2 to 3 minutes. Pour mixed material into container large enough to accommodate 77 lbs. of filler and resin. Mix slowly for 3 to 5 minutes until homogeneous mix, gray in color, is achieved.

Note: Do not thin. Solvents will prevent proper cure.


Substrate must be clean and sound. Remove all laitance, oil, and grease by sandblasting, wire brushing, or bush hammering. When used on steel, remove mill scale, rust or any other contaminants and wipe surface clean with approved metal cleaning solvent.

Patching: Clean out defective area and patch with Epoxy.com Product #27 and allow to cure before put into use.

Forming: Epoxy.com Product #27 is a self-leveling material. Seal forms to prevent seepage. Wax inside of forms or use bond-breaking liner to prevent adhesion of grout to form.


Epoxy.com Product #27 may be placed in single or multiple lifts up to 10 inches thick. Apply at ambient temperatures as low as 50�F. Exposure to elevated temperatures for prolonged periods is not recommended. (Use Epoxy.com Product #641LV Heat Resistant Grout up to 400�F).


  • Component "A" is packaged in a 1-gallon can (92.7 fluid oz.)
  • Component "B" is packaged in a 1/2-gallon can (64 fluid oz.
  • Component "C" Aggregate is in an 77 lb. bag
  • Actual yield: .635 cubic feet of grout.
