Application Instructions
- Product Storage: Store product at normal room temperature before using. Continuous storage should be between 60 and 900 F. Low temperatures or temperature fluctuations may cause crystallization.
- Surface Preparation: All new concrete must be cured for at least 30 days prior to application. All dirt, foreign contaminants, oil contamination and laitance must be removed to assure a trouble free bond to the substrate. 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 remove all debris from within the crack opening.
- Product Mixing: This product has a mix ratio of 2 parts 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 mixing may result in product failure.
- Product Application: No priming is necessary. The material can be applied by marginal trowel, putty knife or any other suitable equipment. It is important to thoroughly work the paste into the repair area so as to displace any water from within the repair area. This product can be used underwater as well as in any area where the flow of water cannot be controlled. Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured. It is best to let the floor remain dry for the full cure cycle.
- Recoat or Topcoating: For underwater repairs, we do not recommend any topcoat be applied. Allow Crete Repair UWP to become tack free prior to topcoating. Multiple coats of Crete Repair UWP are acceptable and bond readily. Use xylol for post-application cleanup.
