5 Easy Steps to Paint Skirting Boards Like a Pro

Painting your skirting boards may seem like a small task, but it makes a huge difference! Knowing how to paint skirting boards properly gives any room a polished, updated look - whether you’re painting them to match your walls for a sleek, modern vibe or creating a gentle contrast. Here’s how to get that professional finish on your skirting boards, even if you’re working around carpet. Let’s dive into the steps for a smooth, clean look!

Step 1: Preparing the Surface

A good finish starts with a clean surface! Start by thoroughly cleaning the skirting boards, as dust or debris can ruin an otherwise perfect coat of paint. Use a damp cloth to wipe them down, and a gentle cleaning solution for any stubborn grime. For older boards, a light sanding helps smooth out any rough spots, especially if there’s old paint.

Pro tip: Wondering if you should caulk skirting boards before or after painting? Always caulk beforehand to ensure seamless joints (more on that in Step 3 here!).

Step 2: Apply Masking Tape

To avoid accidental splashes on walls or floors, carefully apply masking tape. Press it firmly along the top edge of the skirting board and along the floor if you’re painting skirting boards with carpet. We shared a hack on our socials for this: apply the masking tape along the bottom of the skirting board onto the carpet, then take a stripping knife and tap down along the edge, tucking the masking tape between the carpet and the skirting board. This prevents paint from getting on the carpet.
Protect your floor by laying down some Covermasq Tape and Drape - this handy product combines a dust sheet with attached tape, saving time and keeping everything in place. This is key for a clean, professional finish.

Step 3: Fill Gaps, Joints, and Nail Holes

Create a smooth, professional finish by filling any gaps or joins between the skirting board and wall. Apply a thin line of decorators’ caulk along the joins, smoothing it with a wet finger or caulking tool to create a flawless line. Next, fill any nail holes with a wood filler that matches your skirting board paint. Once dry, lightly sand these areas until flush with the surrounding surface - a critical step in how to prepare skirting boards for painting.

Step 4: Apply Primer on Bare Wood

If you’re painting new skirting boards or bare wood, applying a primer is essential. Primer helps the paint adhere, enhances the colour, and creates a uniform surface. Don’t forget a knotting solution to prevent stains from knots bleeding through your finished coat. Apply a thin coat of primer with a brush, allowing it to dry completely before moving on to paint.

Recommended primers: Leyland APU, Johnstone's Johncryl, Zinsser Bullseye, or Aqua Guard Primer Undercoat. For knotting solutions, try Johnstone’s Knotting Solution or Zinsser BIN.

Step 5: Apply the Paint

Now, for the fun part—painting! Start with a thin, even first coat, brushing in the direction of the wood grain to minimise visible brush strokes. Use a straight brush for flatter surfaces or a sash brush for detailed moulding. Alternatively, a 2" roller sleeve (like Axus Silk Touch) or a skinny mini roller from Arrowworthy can help achieve a smoother finish. For deeper skirting boards, a 4" roller works well.

Opt for a quality skirting board paint for a durable finish. Paint skirting boards last, after ceilings, walls, and doors, to minimise overlap and maximise precision. You can apply primer or undercoat in between coats on the walls, but save the final coats for last. If you’re nervous about getting a straight edge, try using Masq Sensitive masking tape, which can be safely applied to freshly painted walls.
Once the first coat dries, add a second coat for durability and depth, letting each layer dry fully. The quickest way to paint skirting boards effectively is by following these steps carefully.

Additional Tips for Painting Skirting Boards

Painting walls and skirting boards the same colour is a popular trend for modern, minimalist rooms - it visually expands the space! Check out my other blogs like What is Colour Drenching or My Favourite Colours for Colour Drenching for more on this look.

Can you paint skirting boards with wall paint? It depends on the wall paint type. If it’s a vinyl matt, soft sheen, or silk finish, then no. However, if you’ve used hardwearing acrylic eggshell or durable matt, you can - provided the skirting boards are prepped with the appropriate primer/undercoat. For high-traffic rooms, opt for a more durable finish like Aqua Guard Matt or Satin or Zinsser AllCoat.
