How To Caulk Skirting Boards | DIY Guide | 6 Simple Steps | Video
Caulking Skirting Boards
Caulking gaps around skirting boards is the final touch for a smooth, professional finish. Follow our simple step-by-step instructions for DIY caulking success.
If you already have your skirting boards, you only need two tools to start caulking your skirting boards:
- Caulking cartridge or tube - we recommend acrylic sealant for flexibility and water resistance. Look for a brand that's paintable and crack-resistant.
- Caulking gun - also called sealant or silicone gun. This applies the caulk smoothly and evenly.
Instructions For Caulking Skirting Boards
Step 1 - Prepare the Area
- Clean where the skirting board meets the wall with a damp cloth. Remove any dirt or dust so the caulk adheres properly.
- Ensure the area is completely dry before caulking. Wet surfaces prevent proper bonding.
Step 2 - Apply Caulk
- Load the caulk cartridge into the caulking gun. Clip off the nozzle tip.
- Run a steady 45° angle bead of caulk along the gap between the skirting and wall.
- Don't apply too much! You can always add more if needed after it cures.
Step 3 - Smooth the Bead
- Once applied, run a wet finger or damp sponge along the caulk bead.
- Apply light pressure to push the caulk into the gap and smooth the surface. Eliminate any bumps or ridges.
- Wipe excess caulk away with a dry cloth for a clean finish.
Step 4 - Allow Proper Curing Time
- Let the caulk fully cure before painting or adding more. This prevents shrinkage or cracks.
- Most caulks need 24 hours. Verify the curing time for your specific product.
Step 5 - Add More Caulk if Needed
- Inspect once fully cured. If there are any thin spots or voids, apply additional caulk.
- Smooth and wipe away excess once more. Allow to fully cure again.
Step 6 - Paint the Caulked Surface
- Once cured, paint the caulked areas with trim paint or wall paint to blend seamlessly.
- If gaps are very small, painting the same colour as your skirting boards hides them well.
- For larger gaps, match the wall colour instead to fully conceal.
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.
Caulk vs Silicone
Advantages of Caulk Adhesive:
- Easy to apply: Caulk is easy to apply and can be used in a variety of different applications, making it a good option for DIY projects.
- Dries quickly: Caulk dries quickly, which can be helpful if you're working on a tight schedule or need to finish a project quickly.
- Affordable: Caulk is generally more affordable than silicone, which can make it a more accessible option for those on a budget.
Disadvantages of Caulk Adhesive:
- Can crack or shrink: Caulk can sometimes crack or shrink over time, which can lead to gaps and other issues with your skirting boards.
- May not be water-resistant: Not all types of caulk are water-resistant, so it may not be suitable for all applications, especially if you plan to use it in areas that are prone to moisture.
- May not be as durable: Caulk may not be as durable as silicone and may need to be replaced more frequently, which could be an issue if you want your skirting boards to last for a long time.
Advantages of Silicone Adhesive:
- Flexibility: Silicone is a flexible material that can expand and contract with changes in temperature and humidity, making it ideal for use in areas that experience a lot of movement, such as skirting boards.
- Water-resistant: Silicone is water-resistant, which means it can be used in areas that are prone to moisture, such as bathrooms and kitchens.
- Long-lasting: Silicone is known for its durability and can last for many years without needing to be replaced.
Disadvantages of Silicone Adhesive:
- Difficult to remove: Once silicone has been applied, it can be difficult to remove without damaging the surface it has been applied to, which could be a problem if you need to replace your skirting boards.
- Takes longer to dry: Silicone takes longer to dry than other materials such as caulk, which means it can be more time-consuming to work with.
- More expensive: Silicone is generally more expensive than caulk.
Pro Tips For Caulking Skirting Boards
You've read the guide and are ready to start caulking skirting boards! Here are 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 skirting boards.
- 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.
