How To Caulk Skirting Boards

Step 1 - Prepare the Area

Before applying any caulk to your skirting, you're going to need to clean the area where the skirting board meets the wall with a damp cloth. Remove any dirt or dust so the caulk can adhere properly.

Note: be sure to check out our accessories where you'll find our caulk options.

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.
