PRIMER

None necessary

TOPCOAT

Optional

LIMITATIONS

  • Color stability may be affected by environmental conditions such as immersion service, temperature, or chemical exposure.
  • Colors may vary from batch to batch. Therefore, use only product from same batch for an entire job.
  • 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.

 INSTALLATION INSTRUCTIONS

PRODUCT STORAGE

Store Product #2708 Under Water Pourable Epoxy Crack and Joint Filler at normal room temperature before using. Continuous storage should be between 60 and 90° F. Low temperatures or temperature fluctuations may cause crystallization.

SURFACE PREPARATION

The most suitable surface preparation would be a fine brush blast (shot blast) to remove all laitance and provide a suitable profile. All dirt, foreign contaminants, oil and laitance must be removed from within the expansion joint to assure a trouble free bond to the substrate. However, this product can successfully be applied to damp, wet or even underwater substrates.

MIXING

Product #2708 Under Water Pourable Epoxy Crack and Joint Filler has a mix ratio of two parts A to one part B by volume. Normally, the product comes supplied in pre-measured kits. The most accurate way to measure mixing proportions would be by weight (11.6 pounds part A to 5.65 pounds part B although volume ratios at 2: 1 can be utilized). We highly recommend that the kits not be broken down unless suitable weighing equipment is available. After the two parts are combined, mix well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free. Make sure to scrape the sides and bottom of the mixing container thoroughly when mixing. Water will not impede the cure mechanism for this product. Improper mixing may result in product failure.

PRIMING

Primer is not necessary.

PRODUCT APPLICATION

The mixed Product #2708 Under Water Pourable Epoxy Crack and Joint Filler can be applied by pouring the mixed material directly into the crevice or expansion joint to be repaired. Remove any excess material with a putty knife or similar tool when not underwater. If applying the material underwater, then remove any excess with a scraper type tool after is has partially set up and tacked off. Because of the vastly differing types of applications possible for this product, we recommend that a representative sample be placed and evaluated prior to commencing any large job application.

When applying this material underwater, make sure that the material displaces all water beneath the application to assure contact with the substrate which will create a proper bond. The density of the material is greater than that of water and should force out the water when poured into the expansion joint. This product is not intended for small type hairline cracks. When applying material in an expansion joint, a suitable backer rod can be used provided it is not made of material that will absorb water.

RECOAT OR TOPCOATING

This Product #2708 Under Water Pourable Epoxy Crack and Joint Filler can be applied in successive applications. Topcoating with other products are normally not performed underwater. Always remember that colder temperatures will require more cure time for the product before recoating can commence.

CLEANUP

Use Xylene

FLOOR CLEANING

Caution! Some cleaners and immersion in some fluids may affect the color of the material installed. Test each cleaner or solution if color stability is important and process tested.

RESTRICTIONS

Restrict the use of the area to light traffic and non-harsh chemicals until the material is fully cured (see technical data under full cure).
