Needle Nose Pliers

Removing any type of caulk can be difficult, and acrylic caulk is especially so. However, it becomes an even trickier project when you are working on a painted wall, and trying to avoid damaging the paint. Caulk is designed to stick in its place firmly once it dries, and can take your paint with it as you remove it if you are not careful. However, with the right techniques, you can minimize the damage to your paint, or even avoid it altogether.

Step 1 - Preparing the Caulk

Apply a caulk remover to the caulk. While this will not actually get rid of the caulk, or even separate it, it will soften the caulk and make it easier for you to remove by hand. This will save you a lot of trouble, as caulk is obviously meant to be as difficult as possible to remove. Use the instructions on your caulk remover's packaging to determine exactly how to apply it, and how long to leave it in place for.

Step 2 - Removing the Large Sections

No matter how you do remove your caulk, there will be small pieces left behind. This is unfortunate, but unavoidable. However, using the right techniques will minimize the amount of cleanup you have to do after removing the largest pieces of old caulk.

Wet the caulk you will be working on and the area around it. You can do this quickly with a damp sponge. Put on your protective gloves and get out your utility knife. Use it to get under the old caulk and lever it up, then scrape it away. Do this as slowly and carefully as possible to avoid damaging the paint. Use as little pressure as possible, or you risk losing control of your utility knife.

When you have removed as much as you easily can with the utility knife, stop and wash the area you worked on with dish soap and water, and then rinse it. This will remove loose caulk, and the caulk remover. Be sure not to scrub with the sponge, as this may cause damage.

Step 3 - Removing the Remainder

The best way to loosen small pieces of acrylic caulk is by applying isopropyl alcohol to them. While acrylic caulk is resistant to water, it will soften if exposed to alcohol. Use a sponge to apply isopropyl alcohol to the area you removed caulk from. Allow the alcohol to sit and be absorbed by the old caulk. Watch it carefully to avoid accidents, as isopropyl alcohol is flammable. Use your sponge or a dry cloth to scrub away the loosened fragments.

If any pieces of caulk remain after you're done, either use needle nose pliers to peel them off, or a sponge or rag to scrape them off. However, you may need to simply scrape them off and touch up your paint afterwords.
