Project Instructions
Always wear eye protection and waterproof gloves when working with polyurethane sealant and work in a well-ventilated area.
Step 1
Widen the crack to a minimum of 1/4 inch using a chisel and hammer (the edges of the crack should be vertical or beveled in an inverted “V”).
Step 2
Cut the tip of the nozzle on an angle with a utility knife to match the width of the crack and load into a standard caulk gun.
Step 3
Slowly draw the gun along the joint forcing a bead of repair caulk deep into the crack.
Step 4
Remove excess material with a trowel immediately after placement.
