    Clean out existing caulk and broken grout

    If you want your caulking job to stick and stretch for years to come, make sure you remove food particles, old caulk, and other contaminants. If silicone is present, use a silicone caulk remover. Dry the surface with a clean towel.

    Apply the caulk

    A steady hand is necessary for a smooth bead, so make sure Fido isn’t under foot. Apply the bead 1/8”-1/4” wide to ensure there’s enough there to both stick to the joint and stretch with movement.
