Preparing the Concrete Joint
Filling the Joint
Once the joints are cleaned out completely, it’s time to refill them. We use a urethane joint compound that can flex as it dries to create a strong, permanent bond between the two slabs. Thoroughly mix the joint filler using the manufacturer’s direction, then pour some into a smaller container for increased control and precision.
Pour the compound filler directly into the joint, taking slow passes, allowing time for the filler to sink all the way into the void and ensure the compound reaches the top. Don’t worry about overflow, it’s more important to make sure the joint is 100 percent filled with compound.
Finishing the Concrete Joint
After waiting 18 hours for the joint compound to completely dry, you can then begin the finishing process. Using a compact concrete grinder, go over the joints repeatedly until the joint is flush with the slab. During this process, we highly recommend using a dust collector for safety as well as easier cleanup. Once it’s complete, run over the area with a microfiber mop to get any residual dust and move on to preparing the slab for coating, if needed.
