Everyone has some ugly, cracked caulk, or a string of silicone dangling off the bathtub rim. Here’s how to remove caulk so you can start over with a proper caulking job.
• Utility knife to cut out old caulk
• Heat gun for stubborn caulk
• Putty knife or painter’s 5-in-1 tool
• McKanica® Silicone Caulk Remover or other similar product to remove silicone (if present)
• Mineral spirits or lacquer thinner (for latex and polyurethane caulks)
Outline the caulk you want to remove
Lay off the caffeine here – a steady hand is a must. Use the utility knife to make straight lines on either side of the caulk bead, slightly under the edges. A heat gun will help soften it some to make this a bit easier. This may be all that’s necessary. The bead may lift easily and you’ll be done. If not, proceed to Step 3.
Apply the caulk remover, mineral spirits or lacquer thinner
Don’t spread it all over the place. Keep it to the bond line. It will take some time to work. Follow instructions on the package for wait time.
Use the utility knife, putty knife or painter’s tool to lift up the loosened caulk
Be gentle. Bulls in china shops need not apply here. Cut and lift away a little at a time to preserve the surface around the caulk.
Throw away the stuff you removed, then get yourself some Sashco products to re-do the work.
