Cinder blocks are a popular choice of material for exterior walls, retaining walls and foundations. They are durable, low-maintenance and cost-effective. Unfortunately, cinder blocks can become damaged over time due to weathering, moisture, improper use or poor construction. If your cinder block wall is crumbling, there are a few steps you can take to repair it and restore it to its former glory.
Steps for Repairing a Crumbling Cinder Block Wall
Step 1: Assess the Damage
The first step in repairing a crumbling cinder block wall is to assess the damage. Check for any broken or cracked blocks and look for signs of water damage, such as staining or discoloration. This will help you determine the extent of the damage and the best way to repair it.
Step 2: Remove Loose Bricks and Mortar
Once you have assessed the damage, the next step is to remove any loose bricks and mortar. Use a hammer and chisel to carefully remove the loose pieces. Be sure to wear safety goggles to protect your eyes from flying debris. If the wall is badly damaged, you may need to remove more than just the loose pieces.
Step 3: Clean the Wall
Once you have removed the loose pieces, you should then clean the wall. Use a pressure washer to remove any dirt and debris. Be sure to wear safety goggles, gloves and protective clothing when using the pressure washer. Once the wall has been cleaned, let it dry completely before moving on to the next step.
Step 4: Repair the Cracks and Holes
If there are any cracks or holes in the wall, you will need to repair them before proceeding. Use a masonry patching compound to fill in any cracks or holes. Make sure the compound is compatible with the type of cinder block you are using. Let the patching compound dry completely before moving on to the next step.
Step 5: Replace Damaged Bricks and Mortar
If any of the cinder blocks are broken or cracked, you will need to replace them. Use a hammer and chisel to carefully remove the damaged blocks. Be sure to wear safety goggles to protect your eyes from flying debris. Once the damaged blocks have been removed, you can then use new blocks and mortar to replace them. Make sure the new blocks are securely in place before moving on.
Step 6: Seal the Wall
Once all of the repairs have been made, the next step is to seal the wall. Use a masonry sealer to seal the wall and protect it from water damage. Make sure the sealer is compatible with the type of cinder block you are using. Let the sealer dry before applying a second coat.
