Surface Preparation

Surface must be clean and free of any dust, oil, grease, laitance, curing compounds or any other contaminants. This should be achieved by sand blasting, water blasting or some other mechanical means. New concrete surfaces may be acid etched with muriatic acid and rinsed thoroughly. The surface must be dry or damp, and must be free of standing water.


Mixing & Application

Stir both A & B components before mixing together. Mix equal volumes of Part A and Part B. Mix thoroughly with a heavy duty, low speed drill fitted with a mixing paddle. Mix until a uniform gray color with no streaks is evident. Be sure to scrape the sides and bottom of the mixing pail. Do not mix more material than can be used in 40 minutes. Apply mixed material by trowel, spatula or putty knife. When used as adhesive, cover both surfaces when possible and then bring into intimate contact. Remove excess before curing. When used as a mortar on vertical and overhead patches, limit depth of patch to 1/2-1" to prevent sagging. Allow first layer to set before applying additional material. When used on floors, fill holes up to 4" deep in one layer. Avoid feather-edging. For smooth finish, keep tools lightly "wetted" with mineral spirits.



  • Do NOT apply when temperature is below 50oF.
  • Do NOT apply to latex modified mortar or concrete.

Clean Up

Clean tools and equipment immediately with a suitable solvent such as xylene or lacquer thinner.



For professional use only. Epoxy systems can cause delayed dermatitis. Avoid prolonged contact with skin. See Material Safety Data Sheet for proper handling and required safety equipment.
