How to fill large gaps in skirting boards

Skirting boards are an important decorative feature in any room, serving as a protective barrier and providing a finished look to the walls. However, over time, gaps may appear between the skirting boards and the walls, which can be unsightly and allow dust and dirt to accumulate.

Fortunately, filling large gaps in skirting boards is a relatively simple and straightforward task. With a few basic tools and materials, you can restore the appearance of your skirting boards and prevent further damage.

Step 1: Prepare the area

Before you begin filling the gaps, it’s important to first prepare the area. Remove any loose or crumbling material from the gaps using a chisel or scraper. Clean the surface thoroughly to ensure proper adhesion of the filler.

Step 3: Apply the filler

Using a putty knife or a filling knife, apply a generous amount of wood filler to the gaps. Make sure to push the filler deep into the gaps and smooth it out evenly along the length of the skirting board. Allow the filler to dry completely according to the manufacturer’s instructions.

Step 4: Sand and finish

Once the filler is completely dry, use sandpaper to smooth out any rough edges or high spots. Start with a coarse grit sandpaper and gradually move to a finer grit to achieve a clean finish. Wipe away any dust with a cloth and paint or stain the skirting boards as desired.

Note: It’s important to choose a wood filler that matches the color of the skirting board for a seamless finish. If the gaps in your skirting board are too large to be filled with standard wood filler, you may need to consider using a combination of different fillers or other materials.

Tips for Filling Large Gaps in Skirting Boards

Filling large gaps in skirting boards can be a challenging task, but with the right tools and techniques, it is possible to achieve a seamless finish. Here are some tips to help you fill those unsightly gaps:

  • Measure the gap: Before you begin filling the gap, it’s important to measure its width. This will help you determine the appropriate filling material.
  • Select the right filler: There are different types of fillers available for skirting boards, such as acrylic or silicone-based fillers. Choose a filler that is flexible and will adhere well to the material of your skirting board.
  • Prepare the surface: Clean the area around the gap to ensure good adhesion. Remove any loose paint or debris using a scraper or sandpaper.
  • Apply the filler: Use a caulking gun or a filling knife to apply the filler into the gap. Fill the gap completely, ensuring that the filler is level with the surface of the skirting board.
  • Smooth the filler: Use a wet finger or a damp cloth to smooth the surface of the filler, ensuring a neat and tidy finish. You can also use a shaping tool or putty knife for larger gaps to achieve a smoother finish.
  • Allow the filler to dry: Follow the drying time mentioned on the filler packaging. Avoid touching or disturbing the filled gap during this time.
  • Sand and paint: Once the filler is fully cured, use fine-grit sandpaper to smooth out any rough patches. Wipe away any dust and paint over the filler to match the color of your skirting board.

By following these tips, you can fill large gaps in skirting boards effectively and achieve a professional-looking finish. Remember to always read and follow the instructions provided with the filler for best results.

Assessing the Gap Size

Before filling large gaps in skirting boards, it is important to accurately assess the size of the gaps. This will help you determine the most appropriate filling method and ensure a seamless finish. Here are some steps to follow:

  1. Measure the width of the gap using a tape measure. Start by measuring the shortest distance across the gap, and then measure the widest point. Note down both measurements as you will need them later.
  2. Consider whether the gap is consistent or varies in size. Some skirting board gaps might be smaller at one end and wider at the other. Make a note of these variations as they will affect the filling process.
  3. Take into account the material of the skirting boards. Different materials, such as wood or PVC, may require different filling techniques. Ensure you choose a filling material that is suitable for the specific skirting board material.
  4. Assess the depth of the gaps. This is crucial as deeper gaps might require a two-step filling process or additional support. Use a ruler or depth gauge to measure the depth of the gaps accurately.
  5. Inspect the condition of the skirting board. If there are any signs of damage, such as cracks or warping, consider repairing or replacing the skirting boards before filling the gaps. Filling large gaps in damaged boards may not provide a long-lasting solution.

By thoroughly assessing the size and condition of the gaps in your skirting boards, you can select the appropriate filling method and ensure a professional-looking finish.

  3. Smooth out the filler using the putty knife. Scrape off any excess filler to create a clean and neat finish. Ensure that the filled gap is level with the skirting board surface.
  4. If necessary, repeat the filling process for any remaining gaps in the skirting boards. Allow the filler to dry completely before moving on to the next step.
  5. After the filler has dried, sand it gently to achieve a smooth and seamless finish. Use sandpaper with a fine grit to avoid damaging the skirting boards.
