Whether you are repairing exterior wall damage or mixing up touch-up paint for inside, understanding basic masonry repair can help save you time, money, and tight headaches in the future.
Brick Wall Patching Basics
Patching a brick wall reinforces it and makes it possible to repair damage to the wall. It includes cleaning debris, mixing mortar, and carefully applying it to match the existing brick. Always begin with a sound foundation that is dust-free, free of cracks and lapses where moisture can enter. Patch as soon as possible, as further damage will be much more difficult to repair and make the wall less attractive.

- Trowel set
- Safety gloves
- Mortar mix
- Stiff brush
- Pointing tool
Inspecting the Brick Damage
Upon close examination, you can see what type of repair is needed. Shallow cracks will use less mortar, and deeper voids may require a build-out. Inspect the surrounding brick and mortar to see if they’re strong enough to hold the new patch in place without crumbling. Saturated ground is a possible hazard.
Preparing The Work Area
The work surface should be clean and firm when the mortar is added. Dust, mop, vacuum, or wipe away any loose debris and dirt with water, and be sure to let it dry. This will allow the new mortar to adhere strongly and result in a strong, durable patch for your wall. Clean surfaces matter.
- Surface cleaning
- Dust removal
- Sponge wipe
- Loose debris
- Moist prep
Mixing Mortar Correctly
Prepare mortar mix to blend with the existing color and texture of the concrete. Refer to the manufacturer’s instructions for the water ratio and mixing time. Stir with a small trowel until very smooth. Let it sit for a minute or two before applying so it gets an initial bonding strength and sets. Don’t overbeat or batter, or it won’t be easy to work with.
Applying The First Layer
Begin by packing mortar deeply into the cleaned hole. Start with the first base layer and spread it evenly with your trowel. For holes deeper than 8” or 10”, do it in layers, letting each layer start to firm up before adding more. This prevents later shrinkage and cracking. Good layering means the structures will remain strong for a long time.
- Trowel press
- Layer control
- Smooth base
- Firm fill
- No air
Finishing With Texture Matching
Work with the mortar while it is still fresh and use a brush, sponge, or the edge of the trowel to match the texture of the surrounding area. This repair work is much less visible and preserves the look of the wall. Allow the glaze to dry slowly for a good finish. Subtle details matter.
Fixing Exterior Wall Damage
Materials that stand up to water, temperature fluctuations, and UV rays are required for outdoor repairs. Opt for a waterproof or quick-set mortar. Once the concrete has cured, coat it with a brick sealer and water will stay out. Good caulking means your fix won’t be affected by the weather, or expansion and contraction caused by the seasons. Ensure longevity outside.
- Waterproof mix
- UV resistant
- Strong bond
- Cure fully
- Apply sealer
Curing And Drying Time
Curing is crucial. For the first 24 hours, keep the repaired area a little damp to avoid chipping. Protect from direct sunlight and wind. It may take up to 48 hours for a full cure, depending on the type of mortar and the weather conditions. Patience improves results.
Common Masonry Repair Techniques
Simple masonry restoration can really make your home look better and last longer. Encase deeper repairs with several layers of mortar. For smoother application, keep tools residue-free. With a pointing tool, mold mortar lines and force them into existing joints for a uniform appearance. Practice improves technique.
- Layer application
- Clean tools
- Pointing finish
- Mortar joints
- Texture blending
When To Call A Professional

FAQs
What can I use to fill holes in brick walls?

How do you fill a large hole in a brick wall?
Sweep the hole clean of any loose dirt or dust. Mix up a new batch of mortar and fill the hole in layers, tamping it down firmly. Once the extender has been installed, make sure the surface is smooth, to match the rest of the brickwork, and leave it to set correctly.
How do you close a hole in a brick?
To close a hole in brick, clean the area and dampen it if necessary to improve bonding. Fill with mortar, brick fill , or patching material, depending on the size of the hole. Shape and file it so it melds with the current surface.
How big of a hole can you fill with mortar?
Mortar can generally be used to fill holes several inches wide and deep. For larger spaces, the mortar should be mixed with brick shards or backer material. Very large holes will need some of the bricks replaced or backing in concrete.
