Concrete Crack Filler

Fill in pits, divots, cracks, or any imperfections in your concrete before using your epoxy with this two-part 2 Gallon Epoxy Crack Filler & Concrete Patcher. This is a two-component 100% solids epoxy crack filler designed for shallow repair on either vertical or horizontal surfaces. This product is easy to mix and use and has a non-critical mix ratio. In addition, because it is a 100% solids formulation, it can be applied thicker on horizontal surfaces when required. Recommended for repairing cracks, pits, divots, and defects in concrete or masonry. Used by flooring professionals for it's durability and instant recoatability.

Cure Schedule (70 degrees F):

• Pot life - 2 gallon volume: 1-3 hours

• Recoat or topcoat: Immediately after application
• Light foot traffic: 10-24 hours
• Full cure (heavy traffic): 2-7 days

Product Storage:

• Store product at normal room temperature before using. Continuous storage should be between 60 and 90 degree F. Low temperatures or temperature fluctuations may cause product crystallization.

Surface Preparation:

• All dirt, foreign contaminants, oil and laitance must be removed to assure a trouble free bond to the substrate. A test should be made to determine that the concrete is dry; this can be done by placing a 4' x 4' plastic sheet and taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet then the substrate is dry enough to start repair work. This product is intended for hairline cracks and other fractures up to an 1/8 inch in width. Remove all unsound concrete from within the crack to be repaired and thoroughly vacuum all debris and dust from within the crack opening.

Product: Mixing:

• This product has a mix ratio of 1 part A to 1 part B by volume. To mix, simply measure out equal volumes of the material and mix them together thoroughly with slow speed mixing equipment such as a jiffy mixer, putty knife or spatula until the material is thoroughly mixed and uniform in color. Mix only an amount of material that can be used in the allotted pot life period. Improper or insufficient mixing may result in product failure.

Product Application:

• The mixed material can be applied by marginal trowel, putty knife or any other suitable equipment.

Recoat or Topcoating:

• When repairing cracks that are less than 1/8" thickness, many epoxies can be placed directly over the applied crack filler before it is cured. Alternatively, it is also acceptable to allow the material to cure before installing the coating. If excessive amounts are spread well beyond the crack repair or in an areas where surface repairs have been implemented, it is best to check the cured areas for any possible amine blush (a whitish, greasy film or deglossing) prior to coating over this material. If a blush is present, it can be removed by any standard type detergent cleaner prior to topcoating or recoating. Many epoxy coatings and urethanes are compatible for use over this product as well as multiple coats of this product.

Cleanup:

• Use Xylol (Xylene).
