- Place masking tape on tub edge, approximately 3/16 of an inch away from the wall.
- Place masking tape about 3/16 of an inch up the wall around the tub.
- Fill tub with water to the overflow height.
- Place caulking between tub and wall joint around tub.
- Get some liquid dish soap and stick your finger into soap and smooth off caulking. Allow extra caulking to go onto masking tape.
