How to Properly Apply Caulk on the Baseboard

Painter's caulk

One of the most important things to do when applying caulk on baseboards is to remove all the old caulk you have in place.

Try using a sharp tool, such as an x-acto knife, to pull it out carefully. This will allow you to eliminate any junk already there and make it easier to apply the new caulk.

Then follow these steps below to apply the caulk properly:

Step 01. Prepare Your Caulk Tube

Cut the tip of your caulk tube at a 45-degree angle. Make sure not to cut it too high or too low. This will make it easier to apply a consistent line along the baseboard.

Step 02. Clean the Debris

Use your tool, such as an x-acto knife, to scrape away any debris from the gaps before applying new caulk.

Step 03. Applying the Caulk

Apply caulk with a smooth and even motion; however, make sure not to overdo it. This can cause spills and messes you’ll have to deal with later on.

Step 04. Smooth it With a finger

Use your finger, such as the one on your non-dominant hand, to smooth out the caulk in a consistent line. Make sure to wipe it away and clean the tip of the tube before you reach the end of your baseboard.

Step 05. Apply Second Layer (If Needed)

If needed, top off any low spots or bare patches with the second layer of caulk. You should wait until the first layer dries before another application.

Step 06. Let the Caulk Dry

Let it dry for around 30 minutes before you do anything else. Make sure the caulk is completely set before moving on to your next project.
