Poor caulking work in the best-case scenario looks unappealing; in the worst case, it can reduce the caulk’s ability to serve its purpose. Specifically, Bumpy or broken caulk lines may fail as a sealant, allowing for moisture to seep in through the bumps. If you would like to repair existing caulking work, you’ll be pleased to know that the process is not a difficult one.

Remove the Old Caulk

To repair a poor caulking job, it’s important to start with a clean slate. This means that you must remove the old layer of caulking. To do so, run a razor knife along both the top and bottom seal, as close as you can get to the line between the caulk and the surface. From there, take a putty knife and attempt to scrape the entire caulk line out in one piece. This will save you time compared to scraping off a small piece at a time.

Once you have removed the caulk line, thoroughly clean the surface with diluted bleach and let it completely dry before beginning a new caulking job.

Applying a Fresh Caulk Line

For a straight caulk line, use painter’s tape to line up your seam. It’s easy to remove from most surfaces and ideal for people who would like to ensure neatness in their finished product. Cut your caulking container’s tip at a 45-degree angle with an opening that is roughly 1/8 of an inch in diameter. Insert the container into the caulking gun and line the tip up with the seam between the surfaces you’d like to seal.

Apply an even line of caulk, working slowly toward yourself to ensure control of your bead. Once you have laid a line, “tool” the line to give it a concave appearance by wetting your fingertip and running it along your caulking line, applying light but even pressure from start to finish.

Touching Up Your Work

Once you have completed your line and smoothed it entirely, carefully remove the painter’s tape before the caulk line has time to cure. Inspect your work for any errors and clean up any stray marks before leaving your caulk lines to cure completely. While your line is curing, it’s important to avoid touching or getting the line wet. If it has been allowed to cure correctly, the seal will look great and provide much better protection than the previous job.
