What Causes Stair Step Cracks in Brick?
1. Thermal Expansion and Contraction
One of the primary causes of stair step cracks in brick is thermal expansion and contraction. As temperatures fluctuate, the mortar used to hold the bricks together expands and contracts more quickly than the actual brick itself. This can lead to stress fractures at certain points that result in visible stair-step cracking.
2. Poorly Laid Bricks
Another cause of stair step cracking in brick is when the bricks are not laid properly. If a contractor fails to ensure that the mortar joints between the bricks are level, there can be uneven stress on both sides of the wall resulting in stair-step cracking.
3. Foundation Issues
Lastly, foundation problems can be the cause of stair step cracking in brick walls. If a building’s foundation is not stable, the walls can shift or move slightly causing stair-step cracking. Also, soil conditions like underground water or soil erosion can cause a building’s foundation to become unstable and result in stair-step cracking.
It is important to determine the underlying causes of stair step cracking in brick before attempting any repair work. Once the cause has been identified, it can be addressed accordingly. For example, thermal expansion and contraction can be controlled by using more flexible mortars and the bricks should be laid properly to prevent poor joint lines.
How to Fix Stair Step Cracks in Brick in 6 Easy Steps
Step 1: Clean the Wall and Remove Loose Mortar
The first step to fixing stair step cracks in brick is to clean the wall and remove any loose mortar that may be present. Use a wire brush to remove any loose debris and then rinse the wall using a garden hose.
Step 2: Fill in the Crack with Mortar
Using a mortar mix, fill in the crack to create a level surface. Make sure that you use enough mortar so that it is just slightly above the surface of the brick wall. Also you have to make sure that the mortar is completely dry before applying any additional sealant.
Step 3: Allow the Mortar to Dry and Set
Once you have filled in the crack, allow it to dry and set for at least 24 hours before continuing with the next step. You have to be patient and make sure that the mortar is completely dry before continuing.
Step 4: Apply a Sealant to the Brick
Once the mortar has dried, you can apply a sealant to the brick. This will help protect it from future damage and give your wall a more polished look. Use a brush or roller to apply an acrylic-based sealant evenly across the entire wall.
Step 5: Allow the Sealant to Dry
Allow the sealant to dry completely before continuing with the next step. This usually takes around 24 hours, so be patient and wait until it is fully dried before moving onto step 6.
Step 6: Paint the Wall
Finally, you can paint your wall to give it a finished look. Choose a light color that will match the rest of the brickwork and paint over the entire wall in an even layer. Allow the paint to dry completely before using the wall.
With these six easy steps, you can quickly fix stair step cracks in your brick wall! Just make sure to take your time and be patient with the process. The end result will be a beautiful wall that you can enjoy for years to come. Good luck!
Some Tips to Fix Stair Step Cracks in Brick
1. Do Not Paint over the Cracks
Painting over cracks will only mask them for a short period of time and eventually, the crack will show through. Instead, patch up the cracks with a mortar mix that is compatible with the existing brick. Also, make sure to use the same color of brick mortar as the existing bricks.
2. Clean the Cracks Carefully
Before filling up the stair step cracks, make sure to clean off any debris or loose fragments in it as best you can with a wire brush. This will help ensure that the patching material has a good surface to bond and adhere to.
3. Fill the Cracks with Mortar
For stair-step cracks that are not too deep, use a premixed mortar patching material. For deeper cracks, mix your own from masonry cement and sand in a 4:1 ratio (4 parts dry mortar mixed with 1 part water). Apply the mixture to the crack using a trowel or putty knife and make sure to fill it up completely.
4. Allow the Patch to Dry and Cure
Let the patch dry for at least 24 hours before you attempt any further repairs. Once the patch is fully cured, go over it with a wire brush to even out the surface and match it with the existing brick. You can also apply a sealant to the area if you would like.
Following these steps should help you easily and successfully fix stair step cracks in your brickwork. With some patience and careful planning, the repairs will be invisible and your wall or structure should look as good as new!
