Steps to Caulk Between Baseboard and Floor

Caulking helps you seal the leaking spots or gaps in the floors. It may not structurally seal gaps like adhesives, but it will help in protecting both the baseboards and floor.

Things You’ll Need

Since caulking baseboards to floor requires both time and effort, it is better to prepare all the necessary tools for a smooth DIY task.

  • Knee pads
  • Old paint brush
  • Putty knife
  • Mild detergent
  • Bucket of warm water
  • Painter’s tape
  • Paintable caulk
  • Caulk gun
  • Clean, dry rugs
  • Paint

Step 1: Wear Your Knee Pad

The first step is to wear some protective measures before caulking. Knee pads will allow you to work until you finish without getting hurt and having scrapes on the knees.

Step 2: Clean the Gap

Caulk will adhere better and last longer to a clean surface before being applied than if it is smeared on. Make sure it is spotless and free of debris.

Use an old brush to clean these corners as there may be dust, pet hair, small toys, or something undesirable hidden here for a long time.

Make sure you brush the baseboard corners gently and with care.

The best thing you can do when dried paints and stubborn dirt are present is to use a putty knife. Then, use warm water and mild detergent to clean the area if there is any remaining debris. Allow it to dry after that.

Step 3: Protect It Using Painter’s Tape

Before filling the gap between hardwood floor and baseboard, you must protect the floor and the baseboard.

Using tape isn’t really necessary, but it will help you in outlining where to caulk for flooring. It eventually all comes down to the baseboard you have installed in your walls. Using tape is not required, just like if your baseboards are stain-resistant.

You must place painter’s tape 1/8 inch away from the base once you’ve decided to use it. Run it parallel to the baseboards on the floor. This will enable you to complete the task with high quality. Aside from that, the tape can catch the excess caulk once you caulk bottom of baseboards.

Step 4: Caulk it up!

Once everything is ready, it is time to seal space between baseboard and floor.

  1. Mount the paintable caulk to the caulk gun.
  2. Start in the corner and gently press the gun while caulking trim gaps. Be careful not to squeeze so much on the corner, as it will only create a mess. In doing so, you should be moving and pressing the gun at the same time. Run it until it reaches the middle.
  3. Then, go to the opposite side and repeat the same process above.
  4. Once it meets in the middle and the gap is full, you can dip your finger in water and gently run it on the applied caulk to smoothen it.
  5. If gaps are found or even small holes, fill them with the caulk gun.
  6. Then, clean it again by smoothening it with your wet fingers.
  7. If the caulk is already set, you can now carefully remove the tape. Do not wait for the caulk to dry since it will be harder for you to remove the tape.

Take note that if you want to fill large gap, you may want to slow down until you fill it with caulk.

Step 5 Let it dry

Let the caulk dry and be completely set on the gaps after removing the tape. Check it after it has dried to see if any tiny holes require caulking. Spot fix any gaps smaller than a pinhole that you find. Once more, let it air dry.

Step 6 Paint the caulk

Leaving the caulk unpainted will only draw dirt and leave an unsightly view. So, make sure you decide on a paint color that matches the baseboards in your room and cover the caulk.

  • Reapply tapes to the floor before painting. Another option is to spread an old rug across the floor. In this manner, any paint that may have been smeared won’t end up on the ground or the remaining baseboard.
  • Then, take the paint and color the caulk that has dried.
