Caulking around your bathtub is not as difficult as you may think. We have compiled some effective tips for you to keep in mind in order to get the job done with minimum hassle. Here is a list of things you should be aware of when you are applying bathtub caulking, which will assist you in getting the job done quickly and with minimal frustration.

Caulking the Points

The best bathtub caulks that you can find in the market are either made out of silicone compounds or acrylic latex. They have been tweaked chemically in order to stick perfectly well with nonporous and smooth surfaces. Moreover, the chemical treatments have provided caulks with mildew-resistant properties.

First of all, you need to figure out what type of caulk you are planning to apply on the bathtub. Silicone caulks are flexible, water proof and tenacious. However, you should also keep in mind that you need to have paint thinner or mineral spirits in order to clean up these caulks, and it is somewhat difficult to smooth. If you prefer convenient smoothing, acrylic latex would be a good option to consider, as it is easily cleanable with water.

Removing Existing Caulks and Surface Cleaning

Before you apply caulks on the bathtub, you will need to remove any existing. It is possible to get the job done with the help of a razor scraper and a 5-in-1 painter’s tool, or a utility knife.

Of course, when you scrub the surface you need to be careful not to cause any damage to the plastic fixtures, which is why it would be a good idea to use a soft rag. You will probably get the best scrubbing results if you use a rag damped in mineral spirit. A nonabrasive pad scour will work, yet can lead to scratching, so a soft rag is best.


Taping is an important step that you will have to go through when applying bathtub caulking. It’s recommended to place two parallel strips of blue painter tape, maintaining a gap of about 3/8 inch between them. If you can keep the bead uniform and straight, you will get the best results.


When all the seams are filled, you can proceed to the last stage - smoothing. For this, use a lint-free rag or a paper towel. If you can pull all the joints in continuous motion, you will see the best results.

The Caulking Gun

Lastly, do not forget a caulking gun. It is highly recommended to test the gun before you start the work! Check some online tutorials to get you started.

Follow these basic steps and with a little time and effort, you will have your bathroom looking brand new!
