Make sure that all surfaces are clean, structurally sound, dry and free from grease. Remove all dirt, oil, moisture,and/or old sealant.
-
Widen crack using a chisel and hammer to at least 1/4” and use wire brush to clean out debris.
If crack depth exceeds 1/2” use Sika Backer Rod to control depth. -
With a utility knife, cut the tip of the nozzle at a 45° angle to the desired bead size, then puncture the seal inside of the nozzle and place the cartridge into a caulking gun.
-
Wearing protective gloves and safety goggles, hold the gun at a 45° angle and squeeze the gun handle to start the flow of sealant. Apply sealant in one continuous application to prevent any air entrapment. One 10.1 oz. cartridge will yield 24 linear feet of sealant in a 1/4” bead.

Gun sealant into joint and dry tool as necessary.
