Preparing the Concrete Joint
Filling the Joint
After shot blasting the joints, it’s time to refill them using Smith’s PolyJF (for joint filler). Thoroughly mix the joint filler using the manufacturer’s direction, then pour some of what you have into a smaller container for increased control and precision.
Pour the compound filler directly into the joint, slowly, taking care to not overflow too much and allowing time for the filler to sink all the way into the void and ensure the compound reaches the top. Smith’s PolyJF is a polyurethane filler that is ideal for this task as it’s durable and ensures tenacious adhesion in both joints and cracks.
Finishing the Concrete Joint
After waiting 18 hours for the PolyJF to completely dry and cure, you can start finishing the slab. We recommend using a concrete grinder to go over the joints until the joint is even with the concrete slab. During this process, be sure to use 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 extra dust and move on to preparing the slab for coating, if needed.
