Have you ever noticed the occasional brick that looks as if it is “shattering” into tiny pieces? This phenomenon is called spalling and can occur due to a variety of causes. While not usually structurally threatening or dangerous, it’s still important to repair the damage before it gets any worse. This blog post discusses everything you need to know about repairing spalling bricks on your building’s exterior walls.
We will cover the most common cause of spalled bricks, such as moisture penetration and freeze-thaw cycles, how to identify and prevent future problems, and finally, give tips on how best to go about repairs.
Through these steps, you’ll be able to make sure your bricks look like new again – whether they are being used on a structure or simply used in crafts! Read on to learn more about how to repair spalling bricks.
What Can Cause Spalling Bricks?
The most common cause of spalled bricks is moisture penetration. When water gets into the tiny spaces between bricks, it can freeze and expand in cold weather conditions, causing the brick to chip away or crack. This phenomenon is known as frost heaving or “frost cracking.”
Additionally, chimney flue gases and acid rain can also cause spalling. In the case of chimney flue gases, they are often hot enough to cause the brick to expand and crack, leading to spalling. Acid rain is another culprit – its acidity erodes away at the mortar between bricks, leaving them vulnerable to being chipped away by wind or weather conditions.
How Can You Identify Spalling Bricks?
When trying to identify and prevent spalled bricks, look out for signs of water damage, such as discoloration or staining of the mortar. Crumbling and cracking of the brick itself is also a sure sign that the brick may be affected by one or more of these causes.
Additionally, some bricks may be more vulnerable to spalling due to their location. Bricks that are located in shaded areas or near trees and plants can be affected by moisture infiltration from condensation or damp air.
Whenever you notice signs of potential spalling, taking the necessary steps to repair and protect your bricks from further damage is important.
What Will You Need?
Before attempting to repair spalling bricks, you will need a few supplies. These include:
- Chisel and hammer
- High quality masonry cement
- Masonry sealer
- Sandpaper or wire brush
- Safety glasses
Once you have the necessary supplies, you’ll be ready to start repairing your spalled bricks.
10 Easy Steps on How to Repair Spalling Bricks
Step 1. Remove Any Loose Pieces of Brick
To begin, use a chisel and hammer to remove any loose pieces. This will help you gain access to the affected area. If the brick is cracked or crumbling, be very careful when doing this step.
Step 2. Prepare the Area for Repair
Once all loose pieces are removed, use a wire brush or sandpaper to roughen up the surface before applying masonry cement. You can also use a wire brush to remove any dirt or debris from the affected area. It will also help to apply a masonry sealer before you begin the repair process.
Step 3. Apply Masonry Cement
Apply high quality masonry cement using a trowel to fill in any gaps and cracks between bricks. Make sure that it is evenly spread out and level with the existing brick surface. This will help to create a strong bond between the affected area and the new masonry cement.
Step 4. Allow Enough Time for Drying
Depending on your climate, the masonry cement may take one to three days to dry completely. Don’t be tempted to rush the process – it’s important that you allow enough time for it to dry completely before moving on to the next step. As a safety precaution, it’s also best to wear safety glasses when performing this step.
Step 5. Smooth Out the Surface
Once the masonry cement has dried, you can use a trowel to smooth out the surface of the newly repaired area. This will help create an even and consistent finish when finished. Keep in mind that you may need to repeat this step multiple times until the surface is smooth and even.
Step 6. Apply More Cement if Needed
If any areas don’t look quite right after smoothing out the surface, you can apply more masonry cement to fill in any gaps or cracks before moving on to the next step. Make sure it’s level with the surrounding brick surface. If you need to apply more cement, allow enough time to dry before continuing.
Step 7. Brush Away Excess Cement
Once all repairs have been completed and the masonry cement has dried completely, use a wire brush to remove any excess material from around the affected area. This will help ensure that your bricks are smooth and even after repair. Check for any areas that may need additional work, such as filling in gaps or cracks.
Step 8. Apply Masonry Sealer
Using a spray-on or brush-on masonry sealer, coat the newly repaired area to help protect it from moisture. This will also give the bricks an additional layer of protection against staining, discoloration, and other damage caused by wind or weather conditions. Be careful not to apply too much sealer, as this could cause the bricks to appear discolored or stained.
Step 9. Re-Grout if Necessary
If areas around the brick have been damaged due to water infiltration, you may need to re-grout them with fresh masonry cement before applying a sealer. To do this, use a trowel to remove any old grout and then apply fresh grout according to the manufacturer’s instructions. Remember, this step is only necessary if the brick has been damaged due to water infiltration.
Step 10. Enjoy Your Newly Repaired Bricks
Once you’ve completed the above steps, your spalled bricks should be as good as new! They’ll be protected from further water infiltration and damage and look great too. Enjoy your newly repaired bricks!

5 Additional Tips and Tricks
- When repairing spalling bricks, use a trowel to spread the mortar evenly.
- Make sure that you use the right type of mortar. This should match the original mortar used in the construction of the brick structure.
- To reduce cracking, use a masonry sealer to coat the surface before and after repairs have been made.
- If necessary, use a wire brush to clean off any debris on the brick surface before making repairs.
- For additional support when repairing spalling bricks, consider using metal anchors that are designed specifically for this purpose. These will help ensure that no further damage is done to the existing structures while reinforcing them against future damage from weather or other environmental conditions.
By following these tips and tricks, you can be sure that your repair job will look great and last for years to come! Proper maintenance and care will restore the spalling bricks in your structure to their former glory.
6 Things You Should Avoid
- Avoid using too much mortar, as this can cause extra strain on the brick structure and even lead to cracks in the bricks.
- Do not use regular cement for repairs; only use specifically designed masonry mortars.
- Never attempt to repair spalling bricks without the proper safety gear and tools.
- Don’t cover up any existing damage with paint or sealant, as it could further weaken the brick surface.
- Avoid cutting into the bricks when repairing them; doing so will weaken their structural
- integrity and could lead to more serious damage down the line.
- Do not use regular household tools for repair; instead, invest in quality masonry tools.
Following these tips can help you save time, money, and energy while still ensuring a safe and successful repair job! With a little bit of patience and the right tools, you can repair spalling bricks like a pro.
