Step-by-Step Guide to Repairing Cracks
1. Assess the Damage
First, measure the width of the crack:
- Hairline to 1/8 inch: Typically cosmetic and can be filled with masonry caulk.
- 1/8 to 1/4 inch: Usually needs mortar repointing.
- Wider than 1/4 inch: May point to structural problems. Consult a professional mason.
2. Gather Your Tools & Materials
What you need depends on the size of the crack.
- For small cracks, Masonry caulk, a caulking gun, and a wire brush.
- For mortar repair: Type N or Type S mortar mix, pointing trowel, and jointer.
- Extras: Bucket, sponge, spray bottle, gloves, goggles, and a dust mask. They are a must when you’re working around dust and debris.
3. Clean the Crack Thoroughly
Preparation is key. Use a wire brush to scrub out any loose debris and crumbling mortar. For larger cracks, a chisel can be used to clean out the damaged joint so new material can adhere properly. After cleaning, lightly spray the cracked area with water. This prevents the wall from absorbing moisture from the mortar too quickly, which can cause weak joints.
4. Apply the Repair Material
- For Caulking: Cut the nozzle of the masonry caulk tube at a 45-degree angle. Squeeze it smoothly and slowly into the gap. Press the caulk into place and shape it to fit the existing joint with your finger or a pointing tool.
- For Mortar Repair (Repointing): Mix mortar to a peanut butter-like consistency. Press the mortar firmly into the cleaned joint using a pointing trowel. Pack it tightly and overfill slightly to ensure complete coverage.
5. Tool and Finish the Joint
After filling, shape and smooth the fresh mortar with a jointer tool so that it blends with the surrounding joints. This step isn’t just cosmetic—a properly finished joint helps with water runoff and durability.
6. Curing and Clean-Up
For the first few days, keep the repaired area moist. This helps the mortar cure slowly and gain strength. Mist the area lightly with water a few times a day. Once completely dry, use a sponge and water or a masonry cleaner to remove any remaining mortar.
Preventing Future Cracks
Want to avoid more cracks in the future? Here are some quick tips:
- Check for Drainage Issues: Make sure water flows away from your home.
- Inspect Your Foundation Annually: Look for settling or erosion.
- Keep Gutters Clean: Overflowing water can seep into your walls.
- Hire Qualified Installers: From the start, good work saves long-term hassle.
