How to Caulk for a Woodstove Pipe

Caulking your wood stove pipe properly will ensure your safety.

Caulking a wood stove pipe is a simple, yet extremely important, do-it-yourself project. Without the proper caulking applied to the pipe, smoke can seep back into the room instead of being channeled outside. It is essential that you use a proper acrylic latex silicone caulk and apply it properly to the stove pipe. With a basic caulking gun, caulk and some patience, you can effectively seal your pipe and ensure your safety.

Things You'll Need

• Utility knife
• Acrylic latex silicone caulk
• Caulking gun
• Nonabrasive pad
• Putty knife
• Paper towel

Instructions

1. Cut the tip of the caulking tube at a 45-degree angle with a utility knife. Puncture the inner seal of the tube by inserting a nail or the spear on the caulking gun down through the tip.

2. Insert the acrylic latex silicone caulk tube into the caulking gun. Prep the tube by squeezing on the trigger to release a small amount of caulk.

3. Clean the stove pipe surface. Use a nonabrasive pad to clear the surface of dust and grime. If there is old caulking on the pipe, scrape it off with a putty knife.

4. Apply the caulk to the stove pipe. Continuously pull the trigger and work your way around the stove pipe slowly to ensure a steady and continuous bead of caulk. Apply the caulk at a 45-degree angle and make sure the caulk fully covers the seam of the wood stove pipe.

5. Smooth the caulk with your wet finger. You can also moisten a paper towel to smooth the caulk evenly over the pipe's surface.

6. Let the caulk dry 24 hours before using the stove.
