Product #2708 Under Water Pourable Epoxy Crack and Joint Filler is a two component 100% solids epoxy designed for applications where contamination from water cannot be controlled or for underwater repairs and applications. This is a special manufacture item. Typically there is a 36 gallon minimum order. If you need less please contact us to see if we have any smaller quantities made up.
Product #2708 Under Water Pourable Epoxy Crack and Joint Filler is recommended for repairing defects in concrete, cement or masonry products underwater or on wet substrates .
None necessary
Optional
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.
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.
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.
Primer is not necessary.
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.
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.
Use Xylene
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.
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).
