DIY: Save Energy by Caulking Your Fireplace
Caulking Your Fireplace
Caulking your fireplace may be a good idea if you want to save energy. Before you caulk your fireplace, be sure that it is completely cooled down and has not been in use for at least three days. You will also need to purchase fireproof caulk. Follow these steps and you will have yourself a more energy-efficient fireplace!
- Put on work gloves, a dust mask and safety glasses. Protect the hearth and adjacent flooring or carpet, using a drop cloth. Open the fireplace screen fully and remove the log grate from the fireplace.
- Remove ashes and debris from the floor of the fireplace, using a wet-dry vacuum. Remove soot from the mortar joints at the sides and back walls of the fireplace, using a stiff-bristle brush.
- Inspect the vertical and horizontal mortar joints for cracks or flaking. Remove loose mortar at these areas, using a 3-inch cold chisel and hammer. Use the brush to remove any residual mortar from the areas of repair. Clean up the debris with the vacuum.
- Set up a caulking gun with a tube of silicate-based refractory cement caulking. Cut off the tip of the tube to make a 1/8-inch opening, using a utility knife.
- Caulk the prepared areas in the mortar. For the best results, use a continuous motion as you draw the tip of the tube along a crack. You may need to use multiple layers for wider cracks. Allow the caulking to dry before using the fireplace.
