Mix only as much Splash Zone Epoxy and Underwater Epoxy Paste Product #2707 as you can use within 20 min. or less at 70 degrees F.  If the temperature is higher your working time will be much shorter. It is always better to start with smaller batches and to gradually increase the size, to be sure that you have enough working time. Material temperature should be a minimum of 60°F for ease of mixing. Mix "A" & "B" Components together, by hand, until a uniform gray color is achieved.


Remove all deteriorated material, barnacles or other marine growth by mechanical abrasion, water or sand blasting. Typically the better the surface preparation, the better the bond. To avoid contamination, apply Splash Zone Epoxy and Underwater Epoxy Paste Product #2707 to prepared surface as quickly as possible. It is always best to do a mockup to verify that your surface preparation is adequate. 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.


For best results, apply Splash Zone Epoxy and Underwater Epoxy Paste Product #2707 by hand using tight-fitting rubber or plastic gloves. (Wet gloves with slightly soapy water before working with material.) Press material onto surface and knead into place in maximum lift thickness of approximately 2". Smooth gently by rubbing with gloves using water as a lubricant. For smaller areas you can use a concrete grout bag.


Do not thin Splash Zone Epoxy and Underwater Epoxy Paste Product #2707. Since conditions content vary greatly, it is recommended that a sample application be made to ensure the intended performance. Do not apply when water or ambient temperature is below 50°F.


One (1) gallon of Splash Zone Epoxy and Underwater Epoxy Paste Product #2707 will yield 231 CI and cover 12.8 SF @ 1/8" thickness 125 mil.


One (1) years for Components "A" and "B".


  • Color stability may be affected by environmental conditions such as immersion service, temperature, or chemical exposure.
  • Colors may vary from batch to batch.
  • This product is not UV color stable and will discolor when exposed to UV rays or some indoor lighting such as sodium vapor lights.
  • All new concrete must be cured for at least 30 days prior to application.
  • It is advisable to place test patches prior to undertaking underwater or water contaminated repairs to insure product and surface compatibility.
  • The temperature of the water may increase or decrease the time for the material to cure, dependent on the temperature of the water.
  • Physical properties are typical values and not specifications.


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


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.


No priming is necessary.


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.


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, contact Epoxy.com Technical Support for a recommendation for your specific project.


Use Xylene.


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.
