Repairing a masonry chimney
To repair a masonry chimney, you will only need the right tools and knowledge about the task.
- Use a grout rake to remove the masonry. Use a hammer and chisel for harder areas.
- Use the rake to enlarge the joints. Clean the dust using a vacuum. The dust could cause you trouble later in the operation.
- Using a wire brush, clean any dust on the joints and vacuum once more.
- To make the new adhesive adhere to the material better, spray some water on the joints.
- Prepare a masonry and fortifier mix. It must have a thick consistency but must be easy to work with.
- Place masonry on the hawk and pack the joints with it, using a tuck-pointing tool.
- Let the masonry harden for half a hour and remove any excess. Thus, the joints will be flush with the bricks.
- The masonry must be sprayed with water to avoid fast drying and cracking.
- Any excess sand and dust must be removed using a stiff broom. Repeat the cleaning a few days after the masonry has been repaired.
- The masonry must absorb all the water before it can be used.
- Do not attempt any repairs on the masonry if it is still hot
- Use a safety harness if your roof is steep and/or high.
