Repair A Heat Shield

Chimneys are one place where the application of a heat shield may be needed to keep your house warm.


A heat shield is a chemical coating on a surface that effectively absorbs heat. By absorbing heat, the heat shield removes heat that may be applied to the surface. One example of a place where a heat shield can be used is for chimneys. Chimneys utilize heat shields on the chimney so that heat is absorbed into the chimney line. That way, your home re-absorbs the heat instead of the heat leaving out of your walls and home. You may need to repair or re-apply the heat shielding now and again for effective heat absorption. Does this Spark an idea?


Instructions


1. Stop using the chimney at least 24 hours before cleaning and applying the heat shield application. This eliminates heat exhaust, making it easier to clean without breathing in fumes.


2. Use a ladder to get onto your roof if repairing a heat shield in a chimney. For this task, heat shield repairing is done through the chimney smoke stack. Some professional chimney sweepers and repairmen do work from the bottom-up to clean the chimney, but you will minimize dirtying your home if you work from atop the chimney. All equipment used needs to be chimney length.


3. Clean off any soot or debris that is attached to the surface of the original heat shield. Push the brush down into the chimney and move it around back and forth and in circles all down the length of the chimney. This should remove the soot and debris covering over your chimney wall and original heat shield. Use a flashlight to see how much debris you are removing.


4. Remove old heat shield wraps. This is if the old coating looks like it is peeling off. You will have to focus your chimney brush on those peeled or cracked areas so the coating falls off. You will need to use your gloves to peel these wraps off. This step is only pertinent if the surface had already used a heat shield wrap.


5. Go back down to your home and dispose of all the soot, debris and old heat shield coatings. Make sure you are wearing goggles, gloves and a face mask. The chances of dust and debris moving through the air during this clean-up is very high. Throw out all of the debris in the garbage.


6. Move back up to the roof and put down your chimney length sprayer. Load the sprayer with the canister or canisters of heat shield coating needed by your chimney. This amount may be determined by the length of your chimney.


7. Begin spraying up and down your chimney the new coating. The coating will look like a foam that eventually hardens to form the new heat shield. Try to add extra coating to any general area of the chimney you noticed the most cracks and peels.


8. Let the heat shield foam dry according to the chemical manufacturer directions. Once the foam has dried, you can utilize your chimney again with its repaired heat shield.
