C-JOINT – NEW & IMPROVED

2 Gallon Kit:
Request and read the technical data sheet before use. Remove all dirt and foreign contaminants. Make sure the joint is dry. All loose concrete and previous joint compound must be removed to leave a dry clean sound joint. For best results, edges should be saw cut and backer rods can be used to regulate depths to around 1/2 inch in joint. Mix part A and part B together at the correct mix ratio and mix well with slow speed mixing equipment until uniform in color and consistency being sure to scrape the sides and bottom of the mixing pail thoroughly. Avoid high speed mixing as this could force air into the product. Improper mixing will cause an incomplete cure and soft spots in the joint. Apply the mixed product by pouring the material into the expansion joint to be repaired. Remove any excess material either immediately with a putty knife or allow to cure until it can be cut with a razor type scraper at the joint level.
Cure Schedule: (70°) (2 Gallon Kit):
Pot life………..…………….………………………….25-35 minutes
Recoat or topcoat……………………………………..………..4-7 hours
Light foot traffic…….…………………………………………..8-12 hours
Full cure (heavy traffic)… ………………………………..……….3-5 days
Application Temperature: 60-90°F
Primer: None required
Topcoat: None required. Many epoxies and urethane are compatible.
Recommended For: Recommended for concrete/cement expansion joints in general industry.
Not Recommended For: Not recommended for applications for all acids and chemicals.
*Improper mixing may result in product failure.

Cartridge:
Discard the unmixed portion of mixed material at the start of each application. This product has a very short pot life of 1-2 minutes and should be applied with a dual cartridge caulking gun using the ½” diameter 30 element tip. Apply the mixed product by pumping the mixed material in a continuous motion into the expansion joint to be repaired. Remove any excess material with a razor scraper or similar tool after the material has set up enough to cut through with the razor scraping toll. On areas that are not shaved or leveled with a razor scraping tool, it would be advisable to roughen the surface of the joint compound to maximize adhesion of any subsequent coating. Maintain temperatures within the recommended ranges during the application and curing process. When temperatures are lower, allow more time for this material to cure.
Cure Schedule (Cartridge):
Pot life (150 gram mass) ……….………………….1-2 minutes @ 70°F
Recoat or topcoat…..………………………………1 hour @ 70°F
Light foot traffic……………………………….1-3 hours @ 70°F
(Heavy traffic)…………………………………..3-5 days @ 70°F
Application Temperature: 40-90°F (lower temperatures will require additional cure time)
Primer: None required
Topcoat: None required. However, many types of products can be used as coatings or overlays for the area that has been patched.
