How to Fix the Gap Under Skirting Board?

Understanding the Problem

Skirting boards can sometimes leave a noticeable gap between the floor and the board itself. This can occur due to settling of the house, changes in humidity, or simply poor installation. Before attempting to fix this issue, it's essential to assess the extent of the gap and identify its cause.

Gather Your Tools and Materials

Before starting the repair, make sure you have the following tools and materials:

• Caulk (preferably paintable)
• Caulking gun
• Wood filler (if necessary)
• Putty knife
• Sandpaper (fine grit)
• Paint or touch-up paint
• Measuring tape
• Utility knife

Step-by-Step Guide to Fixing the Gap

Step 1: Measure the Gap

Use the measuring tape to determine how wide and deep the gap is. This will help you decide how much caulk or filler you’ll need.

Step 2: Clean the Area

Remove any debris, dust, or loose paint from the gap using a utility knife. Ensure the area is clean and dry for better adhesion.

Step 3: Apply Wood Filler (if needed)

If the gap is larger than 1/4 inch, you may need to first fill it with wood filler. Use a putty knife to apply the filler into the gap, ensuring it is slightly overfilled for easy sanding later. Allow it to dry completely according to the manufacturer's instructions.

Step 4: Sand the Filler

Once the filler is dry, use fine-grit sandpaper to smooth out the surface. The goal is to make it flush with the skirting board.

Step 5: Apply Caulk

Using a caulking gun, apply a bead of caulk into the gap. Move steadily along the line, filling the entire gap while maintaining a consistent width.

Step 6: Smooth the Caulk

With a damp finger or a caulking tool, smooth the bead of caulk to ensure it’s flush with the skirting board. This helps create a clean and professional finish. Wipe off any excess caulk with a damp cloth.

Step 7: Allow to Dry

Let the caulk dry completely, which usually takes around 24 hours. Make sure to check the product instructions for specific drying times.

Step 8: Touch Up Paint

If needed, use touch-up paint to cover the newly filled and caulked area. Allow it to dry completely before moving on.

Final Thoughts

Fixing the gap under your skirting boards can significantly enhance the appearance of your space. Regular maintenance and attention to detail will help prevent gaps in the future. If the problem persists, consider consulting a professional to assess underlying issues.
