Underwater Crack Filler Epoxy Paste

UW601 is a two component 100% solids epoxy gel designed for shallow repair of cracks and defects in concrete or masonry under water or on wet substrates on either vertical or horizontal surfaces. This product is easy to mix and has a non-critical mix ratio. Additionally, the product, because it is a 100% solids formulation, can be applied thicker on horizontal surfaces when required. This product can be used where contamination from water can occur during the cure process or it can be used directly underwater. Available in 3 gallon and 15 gallon kits. PRIMER: None required TOPCOAT: None required.

MIXING AND APPLICATION INSTRUCTIONS

1) PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 50-90°F. Avoid low temperatures and large temperature fluctuations in storage as these conditions could cause possible product crystallization. 2) SURFACE PREPARATION:  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. 3) PRIMER: No primer is necessary. 4) PRODUCT MIXING:  This product has a mix ratio of 2 parts A to 1 part B by volume. To mix, simply measure out appropriate 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. For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer. 5) PRODUCT APPLICATION:  The mixed 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. 6) RECOAT OR TOPCOATING:  For underwater repairs, we do not recommend any topcoat be applied. However, in areas where water contamination may occur during the cure process but subsequent to topcoat application, our NP600L can be used effectively. See the technical data for the NP600 before using or contact your sales representative for further details. Allow the NP601 to become tack free prior to topcoating. Multiple coats of the NP601 are acceptable and bond readily. 8) SURFACE CLEANING:  Caution! Some cleaners may affect the color of the fast set gel installed. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested. 9) RESTRICTIONS:  Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the floor remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.
