Do It Yourself Stucco Repair? (Explained)

The first thing to do when you see a crack in the stucco on your home is to clean it out. This can be done with a wire brush and some mild detergent or even by spraying it with water. 

If the crack is larger than 1/2 inch, then you will need to use an electric drill and putty knife to remove any loose concrete.

Clean the Damage

Before you begin repairing your stucco, it’s important to clean the damaged area as much as possible. 

You can use a pressure washer, stiff brush and vacuum cleaner or soft brush to do this. Make sure you’re wearing protective gear (gloves, goggles) when cleaning because there may be sharp edges on the damaged areas that could cut you if not careful.

When planning a home renovation, it’s crucial to have a solid understanding of how the process works. Consider checking out our informative article on how home renovations work to help you get started on your next project.

Mix the Stucco

Mixing the stucco is a 2-person job. The person mixing should do all of the stirring, while the other person uses a trowel to scrape out any unmixed stucco from around the edges.

When you’re ready to use your mixed stucco, remember that too much water can make your stucco weaker and not cure properly, while too little water will result in cracking and flaking later on. 

Be sure to keep stirring until there are no lumps left in your mixture if you see any lumps coming through after all of this time, add more dry sand or cement until they disappear.

When done with mixing, place your freshly mixed batch of stucco into a wheelbarrow and then transport it over to where it needs to go just don’t fill anything up completely before spreading it! 

You want enough room for air pockets so air doesn’t get trapped under layers of wet material as they dry (which could cause cracks).

Mixing the Stucco

Step 1: Gather MaterialsCollect all necessary materials, including stucco mix, water, and a clean bucket large enough to hold the mixture.
Step 2: Add WaterFollow the stucco mix packaging instructions to determine the correct water-to-stucco ratio, then slowly add the water to the bucket.
Step 3: Mix the StuccoUsing an electric mixer or a drill-mounted mixing paddle, mix the stucco until it reaches a smooth consistency.
Step 4: Remove Unmixed StuccoAs one person mixes the stucco, the other should use a trowel to scrape out any unmixed stucco from around the edges of the bucket.
Step 5: Adjust ConsistencyIf necessary, add additional water or stucco mix to adjust the consistency of the stucco.
Step 6: Use the StuccoOnce the stucco is fully mixed and has the correct consistency, it can be applied to the surface.

Apply Tensile Strength Tape

Tensile strength tape is a mesh-like material that’s applied to the stucco and then wrapped around the joints on both sides of the wall. 

This helps to reinforce the damaged area so it can better withstand wind and other forces that may cause cracks in your stucco repair job. To apply tensile strength tape, you’ll need:

  • Taping knife
  • Roller (optional)

To begin applying tensile strength tape, measure roughly where each piece should go along your affected area; this will ensure you’re able to cover everything as needed while keeping things neat and tidy. 

Next, cut out strips of tensile strength tape with a taping knife or scissors depending on what kind you have available (if not just use what’s readily available). 

Once stripped away from their backing sheet, use these strips as guides for cutting out pieces with scissors or another sharp tool like an X-Acto blade until all pieces are appropriately sized for application onto your damaged surface without being too small for effective bonding or too large for easy application & removal between surfaces in contact with each other when pressed together during installation work such as laying bricks down once they’ve been installed properly so that water doesn’t seep between tiles themselves causing problems over time).

The First Scratch Coat

Once the scratch coat has been applied, it’s time to apply a second layer. This is called the “first finish coat” and can be applied using either a trowel or a hawk. 

In order to ensure that this layer gets an even application, make sure that both your tools and your surface are clean and dry before you begin.

Second Scratch Coat

The second scratch coat is also known as the finish coat. This layer of stucco is applied to cover the first scratch coat. 

It can be applied either wet or dry, but the best results are achieved by applying it wet. This layer should be applied using a trowel and thick enough to give you good coverage and smoothness. The best tool for applying this layer is a float, which can help you achieve a smooth finish.

After you’ve applied this layer, let it dry for 24 hours before painting or sealing your stucco walls (if applicable).

Apply Brown Coat

After the white coat is dry, it’s time to apply the brown coat. You can use a brush or sponge to apply this layer of stucco, but we recommend using a paint roller because it’s more efficient and less messy.

Make sure you don’t apply too much brown coat! It will take longer for your repair job to dry if there is too much material on top of your existing stucco. 

If you’re unsure how much material to use, just follow this simple rule: less is always better than more when it comes to applying any type of paint or coating material onto masonry surfaces like concrete blocks or cinderblocks (and yes, those are two different things).

After applying the brown coat, let it dry overnight before applying another layer of water-resistant coating (that would be called a “primer”) overtop if needed we’ll go into detail about primers shortly! 

Applying the Brown Coat

Step 1: Prepare the SurfaceEnsure the surface is clean, flat, and free of debris. If necessary, apply a bonding agent to improve adhesion.
Step 2: Mix the StuccoFollow the instructions on the stucco mix packaging to prepare the mixture.
Step 3: Apply the StuccoUse a paint roller to apply the brown coat of stucco evenly over the surface. Make sure to work in small sections to avoid drying too quickly.
Step 4: Smooth the StuccoOnce the stucco has been applied, use a trowel to smooth out the surface.
Step 5: Create TextureIf desired, use a trowel or sponge to create texture on the surface of the stucco.
Step 6: Allow to DryAllow the brown coat of stucco to dry completely before applying the finish coat.

Note: The exact steps and materials required for applying the brown coat may vary depending on the specific project.

Stipple Brown Coat

To apply the brown coat, you can use a brush, roller or stipple gun. The key to getting a good finish is to make sure you have the right texture on your first coat of stucco. 

This can be achieved by mixing in some sand or pea gravel with the cement and water mixture before applying it to your wall.

If you’re not confident in your abilities with a paintbrush, then we recommend you hire an experienced painter who has experience working with stucco repairs before attempting this yourself.

Trowel Hard Coat

To apply hard coat, you’ll need a trowel and some patience. Apply the hard coat in thin layers and allow each to dry before sanding it down with 220-grit sandpaper, making sure to remove all dust before applying another layer of hard coat. 

A brush can also be used instead of a trowel for application if you don’t mind getting messy!

Apply Color with a Sponge and Brush

To apply the color, you’ll need a sponge and brush. Use the right color for your area, but don’t overdo it! If you have a lot of stucco repair to do, using too much water can cause serious problems.
