Step by Step Guidelines on How to Repair Mortar Cracks in Brick Wall
Step 1: Clean Out the Crack Area
First, use a masonry trowel to clean out any loose or crumbling mortar from the crack area. This will help clear a space where you can apply fresh mortar. If there is any vegetation or dirt in the crevice, make sure to use a brush to clear it away. Cleaning the area properly will ensure better adhesion and a stronger bond between the existing mortar and the new mortar.
Step 2: Prep Mortar Mix
Once you have cleaned out the crack area, prepare your mortar mix. This can be done by mixing together equal parts of water and dry cement in a bucket, stirring until it forms a paste-like consistency. Preparing the right amount of mortar mix is essential – too much and you will have a wasted product, too little and you won’t be able to fill up the entire crack.

Step 3: Fill the Crack with Mortar Mix
Now you’re ready to fill the crack area with your mortar mix. Start by wetting down the brick wall with a water hose, then use your masonry trowel to carefully apply and smooth the mixture into the crevice. Make sure it is evenly distributed, as this will help ensure a better seal and longer-lasting repair.
Step 4: Finish the Repair Process
Once you are done filling the crack area, use your brush to blur out any excess mortar mix and create an even surface. Allow the mixture to dry completely before moving on to other projects – this should take around 24 to 48 hours depending on the climate. Remember, proper drying time is essential for a successful repair.
By following the steps outlined above, you should have no problem repairing mortar cracks in brick wall surfaces. The process might take some extra effort and patience, but it will be worth it in the end when you see your walls looking good as new!

Things You Should Consider to Repair Mortar Cracks in Brick Wall
- Check the stability of the wall – Make sure that the brick wall is still stable before attempting to repair mortar cracks in it. You should look for any signs of crumbling or settling, and take action accordingly.
- Remove the loose mortar – Carefully remove any loose or crumbling mortar from around the crack. This will provide a fresh surface for you to work with and ensure that the repair is effective and holds up over time.
- Clean the area – To create a stable base for your repair job, it’s important to clean away as much debris as possible. Use a wire brush to scrub away any dirt or debris that might be in the crack, and make sure it is free of dust or other materials that could interfere with the mortar repair process.
- Mix the mortar – Mix up the mortar according to instructions, usually just water and cement mix. If you need advice on how much water or cement to use, it’s best to consult a professional.
- Fill the crack – Using a trowel or similar tool, fill the crack with the mortar mix. Make sure you get as much of it into the crevice as possible for maximum adhesion and stability.
- Cure the repair – After filling in the crack, allow time for the repair to cure before proceeding with any further work or painting. This should take at least 24 hours and may vary depending on what type of mortar mix you used.
Once your repairs are complete, it’s important to maintain the brick wall in order to prevent future damage from occurring. Regular cleaning and inspection can help you identify cracks or other signs of damage before they can become a serious problem. Additionally, if you use sealants or waterproofing treatments on your brick wall, this can help protect it from further weather damage and keep mortar cracks from occurring in the future.
