Looking for any home repair projects to do this weekend? Try repairing a crack in your concrete driveway, patio or sidewalk. It's not rocket science; follow the 5 steps below to get it done right the first time.
1. Surface Preparation
Remove any previously applied caulk or foams, as well as oils, dirt and other contaminants. These all can interfere with the adhesion of Slab or the other caulking you are using. Thoroughly clean the crack with either a stiff bristle brush or a drill mounted brush. Sweep or blow out any debris.
For joints 1/2 inch deep or more, install Sashco® Pre-Caulking Filler Rope™ or another type of backer rod to help save on caulking a provide ideal joint design. Why? See our post on 3 point adhesion.
Cut the Nozzle to the desired bead size. Gun Slab into the crack. For wider cracks (1 inch wide or more), apply 3 beads: 1 on each side of the crack, and another down the middle. This ensures enough product is in the joint, and makes tooling easier.
Ensure the best adhesion and durability by smoothing the bead (also called tooling). Use water and a damp foam brush, trowel or your finger. For best elasticity and durability, make sure Slab is slightly recessed after complete cure.
Clean up any fresh product on surfaces and skin with soap and water. Store any leftovers by tightly sealing the tip with plastic wrap and a rubber band, then store in moderate temperatures (between 50°F and 90°F).
Done! One 10.5 ounce tube of Slab will cover approximately 26 lineal feet with 1/4 inch (6mm) bead. Few home repair projects this easy have such great results!
