How to apply interior caulking

1 hour | Easy | 11 STEPS

Applying interior caulking is an easy way to reduce uncomfortable drafts and save money on your heating bill. Since cold air can sneak in around windows and doors, you can stop it with interior silicone and latex caulking.

WHAT YOU'LL NEED

Start the job by scraping away loose paint and caulking from around the door or window.

Step

Remove debris with a stiff brush.

The new caulk needs a good base to adhere to.

Step

Here’s a tip!

You can use latex or silicone caulking compound that is coloured, or you can use caulking compound that can be painted.

Step

Cut the nozzle using the lines embossed on the nozzle as a guide.

Step

Puncture the seal at the bottom of the nozzle.

Step

Insert the tube of caulking compound into the applicator.

Step

And you’re ready to go!

Apply new caulking.
