SITE PREP & PROCEDURE
- 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. 29 oz. cartridge yields 70 linear feet.
- Dam up open joints. DO NOT USE on joints that are sloped.
- Gun sealant into joint and allow sealant to level out, dry tool as necessary. However, minimal to no tooling should be needed.
- Clean up all tools, spills, and excess material with clean rags after use. If necessary, use a paint thinner or other approved solvent, such as acetone, following the solvent manufacturer’s precautions.
