Step-By-Step Guide on How to Remove Peel and Stick Caulk

Unless you’re a professional handyman, chances are you haven’t had to remove caulking before. But knowing the proper procedure to remove caulk and replace it with new is a useful skill to have in your repertoire, especially if you live in an older home. Removing peel and stick caulking is relatively simple, but it does require a few tools and a bit of patience. Let’s take a look at how to remove the magic peel and stick caulk.

Step 01: Gather The Necessary Tools And Supplies

Before you begin, it is important to gather the right tools and supplies. You will need a hair dryer that helps you to soften the old caulk. A utility knife will come in handy to scrape off the softened caulk. 

You can also collect a putty knife or razor blade scraper. In addition, you will need mineral spirits to paint thinner, which will help you to clean the surface. Finally, you need to have a new tube of caulk. After you have gathered all of the required equipment and supplies, you can proceed to the next step.

Step 02: Heat Up the Area With a Hairdryer

Once you have gathered all your tools, the next step is to use a hair dryer to warm up the area. The device acts as a caulk remover. In doing so, the adhesive on the caulking will be loosened, allowing it to be more easily removed. Start by holding the hairdryer about six inches away from the caulk and moving it back and forth until the caulk is soft and pliable. The process will take some time.

Step 03: Scrape Off The Old Caulk

Now that the area is nice and warm, it’s time to start scraping away the previous caulk. A utility knife is the best tool for this job, but you can also use a razor blade scraper or a putty knife. Just be careful not to damage the surface underneath the caulk. 

Start by running the blade of your chosen tool along the edge of the caulk, then gently pry up the old sealant and peel it away. If the caulk is stubborn, you may need to go over it a few times with the utility knife. You may utilize the hair dryer heat gun to soften the caulk further if necessary.

Step 04: Clean Up the Leftover Caulk and Adhesive

After you’ve removed the caulk and adhesive, it’s time to remove the caulk residue. Take a little paintbrush and clean out any caulking that’s left behind in the cracks and crevices. Accumulate the residue on a paper towel for easy disposal. When you’re finished, the surface should be clean and free of any caulking or adhesive.

Step 05: Apply Mineral Spirits

Once you have removed as much of the caulk and adhesive as possible, it is time to apply mineral spirits. This will help to dissolve any remaining residue, and the stickiness should be gone. Pour a small number of mineral spirits paint thinner onto a cup and apply it to the surface with a brush or cloth. 

Make sure to wear gloves to avoid getting mineral spirits on your skin. Make sure to completely saturate the area. Allow the chemical to sit for a few minutes, then wipe them away with a clean cloth. As a result, you should have a clean surface that is ready for the new caulking.

Step 06: Apply the New Caulk

The new caulk can now be applied once the surface is clean and residue-free. Cut the caulk strip to the desired length and apply the caulk to the bathtubs, showers, or wherever you wish. 

Make sure you apply it at a 45-degree angle. By doing so, you can create a nice, clean edge. Apply even pressure as you move the caulk strip along the surface. Make sure to smooth out any air bubbles that may form.

Step 07: Let the Caulk Dry

After you have applied the new caulk bathtub, stick tile, or another area, it’s important to let it dry completely and use the area afterward. As a result, the caulking has a sufficient bond to the surface. Finally, after the caulking is dry, you can go ahead and use the area as normal.

As you can see, removing the peel-and-stick caulk is not difficult. With the right materials and tools, you can effectively dislodge the old caulking and apply a new extra-wide caulk strip.

Frequently Asked Questions:

There are a few questions that are commonly asked when it comes to removing the peel-stick caulk. Below, you will find some of the most frequently asked questions, as well as their answers.

1. How Long Does It Take for the Caulk to Dry?

This depends on several factors, such as the type of caulk used and the conditions of the room where the caulk is applied. Generally speaking, most types of peel-and-stick caulk will take 12 hours to dry completely. However, if the room is particularly humid or the temperature is too low, it can take more time to dry the caulk. For best results, make sure to follow the manufacturer’s instructions carefully and give the caulk ample time to dry prior to attempting to use it.

2. Can You Dry Caulk With a Heat Gun?

While you can use a heat gun to dry caulk, it is not the recommended method. Caulk is designed to set and cure in contact with air, so using a heat gun will actually prevent the caulk from properly setting. In addition, the high heat of a heat gun can damage the surrounding area, making it more likely that the caulk will fail. For these reasons, it is best to allow the caulk to dry and harden naturally.

3. How Long Does Peel and Stick Caulk Last?

A number of factors determine the answer to this question, including the type of caulking applied and its quality. Generally speaking, peel-and-stick caulk will remain effective for a considerable period of time if it is applied to a smooth, clean surface. 

However, if the caulk is applied to a porous or rough surface, it will probably only last for a year or two. Furthermore, if the caulking is exposed to sunlight or extreme temperatures, it will break down more quickly. Ultimately, the lifespan of the caulk depends on a variety of factors, but it can be expected to last for several years under normal conditions.

4. Can You Apply a Second Layer of Peel and Stick Caulk?

You can apply another layer of caulk, but it is unnecessary. The caulk will adhere to the first layer and create a stronger bond. However, if you are applying the caulk to a very rough or porous surface, it may be necessary to apply a second layer. Ultimately, the decision to add an additional layer of caulk is up to you and will depend on the specific project you are working on.


Removing and replacing this type of caulk is a fairly hassle-free process. You now have a comprehensive understanding of how to remove peel and stick caulk. When you notice that your caulking needs to be replaced, simply follow the steps above to easily discard the old caulk and apply a new strip. Be sure to allow adequate time for the caulk to cure before using the area. In this manner, you can ensure that the caulk is properly bonded to the surface.
