Have you noticed that something just doesn’t look right on your brick wall? Has it seen better days? In the following article, RenoQuotes.com will explain how to replace a brick on your exterior brick wall.
Remove the damaged bricks
Once you have identified the bricks that need to be replaced, you will have to remove them from the wall. Don’t forget to wear gloves and protective glasses while completing the job.
First of all, you’ll have to use a drill to puncture holes inside the mortar that surrounds the damaged bricks. These holes should be a few centimeters deep and should be set according to a regular pattern. Next, using a chisel and a hammer, dig the mortar around the bricks. Once you have removed most of the mortar, remove the damaged bricks. Always work in the most delicate manner you can manage. If needed, use masonry scissors.
Clean out the site of the damaged bricks
Now empty, the place where the damaged bricks used to be will require a proper cleaning and smoothing process before going on to the next step. Use a metallic brush to clean out the surfaces. This step is extremely important as it will contribute to the fact that you will not run into problems when installing the new bricks.
Next, use a hand brush to clean out the cavity. Don’t forget to use a wet sponge in order to humidify all the surfaces around the area where the brick(s) will be. This will serve to ensure that the new mortar you will apply will stick.
Prepare the new bricks and install them
If, when you turn over the old bricks, you notice that some of them are intact on the unexposed side, you could reuse them. However, if both sides are damaged, replace them with new bricks that have the same shape and colour.
Be sure to humidify the bricks before you put them in. You can use grouting mortar (also known as anchoring mortar) to stick the bricks to the surface. This product requires you to mix the powdered grouting mortar with water, which you must stir until you obtain a homogenous mix. You will then have to spread the product on the back side of the brick. Do not apply grouting mortar on the face that will be visible on the wall.
After having prepared your bricks, slowly start placing them in the empty spaces. Make sure that they are well aligned with the others. Using your trowel, shape the joints so they match the others, as this will give an optimal result. When you have completed each step of the process, remove the extra mortar. Lastly, don’t forget to clean up the surface using a wet sponge. Congratulations, you’ve replaced your damaged bricks!
