Caulking Skirting Boards

Fresh new skirting boards that have just been fitted can really alter the look and feel of a room. But wait - are those gaps you can see between the top of the skirting and the wall? Let's fix that by reading this guide on caulking skirting boards.

What Do You Need To Start?

If you're ready to start caulking, all you should is the the following:

  • Decorator's caulk
  • Caulk gun (also known as a Sealant Gun, Silicone Gun, etc.)

Once you have these, you're ready to start filling those gaps!

How Do You Caulk Skirting Boards?

Now we'll get into the guide and show you how to apply caulk to your skirting boards.

1. Make Sure The Area Is Clean

Before applying any caulk, you're going to need to make sure the area is clean.

This is easy enough to do if you've fitted new skirting boards - just use a microfibre cloth to rub the area where the top of the skirting meets the wall.

If you're filling gaps between the wall and existing skirting boards, use a damp cloth to clean the area. Make sure it is full dry before attempting to apply caulk.

2. Apply A Line Of Caulk

Using the caulk gun and the decorator's caulk, apply a line of caulk along the area you want to fill (in this case, a small gap between the wall and the top of the skirting).

Ensure you don't put too much in - you can always add more later.

3. Smooth Out The Caulk Line

Using a wet finger, simply run it across the line of caulk. The wet finger stops the caulk from sticking to you and this process ensures the caulk fills the gap and is finish is smooth and flat.

4. Leave To Cure

Once you're happy and filled in all of the gaps, leave the caulk to cure.

Some manufacturers claim that their caulk is fast drying. However, we always recommend leaving it 24 hours just to make sure.

5. Apply More If Needed

Now you've given the caulk time to settle, you might find that it has sunken into the gaps in some places (especially the wider gaps).

If this is the case, simply apply another line of caulk and repeat steps 3 & 4.

6. Paint The Caulk

The final step is to paint the caulk so that it blends in.

You can either paint it the same colour as the skirting or the same colour as the walls.

If you paint it the same colour as the skirting, depending on the size of the gaps it will make the skirting appear slightly thicker (not noticeable on small gaps).

If you paint it the same colour as the walls, it generally hides the caulk (unless you're actively looking closely at the skirting boards).

Best Caulk For Skirting Boards

As a manufacturer and supplier, it goes without saying that we have the ideal caulk for skirting boards.

Really, most caulks will do the job - you don't have to look for anything too specific.

Ideally you'd choose something that remains elastic after curing. This means it is less likely to crack over time.

Ours is also waterproof once cured (yay for cleaning!) and you can paint over it too.

Caulking Tips

You've read the guide and are ready to start caulking! Here's a few more quick and handy tips:

  • Faster is better - when you're applying a line of caulk, speed is key for a cleaner finish. You'll find that the slower you go, the messier it gets!
  • Acrylic caulk is the best option (less prone to cracks).
  • Any gap over approx. 5mm should be filled properly before caulking.
  • Wipe away any excess caulk before it has time to dry for a professional finish.
  • Thinner layers will dry quicker and leave a more consistent finish.
