When it comes to filling narrow gaps between the floor and skirting boards, there are a few methods you can consider. Here are some common approaches:
Caulk or Sealant: Using a caulk or sealant is one of the most popular methods for filling small gaps. Choose a paintable caulk that matches the color of your skirting boards. Apply the caulk into the gap using a caulking gun, ensuring it fills the space completely. Smooth the caulk with a wet finger or a caulk finishing tool, and wipe away any excess. Once it dries, you can paint over it to match the skirting boards.
Wood Filler: If you have wooden skirting boards, you can use wood filler to fill the gaps. Select a wood filler that closely matches the color of your skirting boards. Apply the filler into the gap, using a putty knife or a small spatula to press it in and level it with the surrounding area. Allow the filler to dry completely and then sand it down until it's smooth. Finish by painting or staining the wood filler to match the skirting boards.
Flexible Gap Filler Strips: Another option is to use flexible gap filler strips, also known as flexible self-adhesive PVC strips or gap seal tapes. These strips are designed to fit into narrow gaps and can be easily cut to the desired length. Simply peel off the backing and press the strip into the gap, ensuring it adheres firmly. Trim any excess material if necessary. Some gap filler strips are paintable, allowing you to match them to the skirting boards if desired.
Before choosing a method, consider the size and depth of the gap. If the gap is wider or uneven, you may need to use a combination of techniques, such as starting with a backer rod or foam filler to fill larger gaps and then using caulk or wood filler to create a smooth finish.
