Stucco Repair – How to Bring Old Stucco Back to Life

Stucco repair is a straightforward process that can bring plaster surfaces back to life. A good quality pigment must be used to match the color of the existing stucco. Use a sanded acrylic exterior caulk for cracks no wider than a dime. This product dries quickly and can be painted later.

Remove the Damaged Stucco

stuccoStucco walls are an attractive and low-maintenance alternative to shingle siding, but they’re not impervious to water damage. If you notice larger cracks or holes in the stucco, a crumbling exterior, or signs of mold growth, it’s time to take action. While there are many solutions for stucco problems, replacing your stucco with durable vinyl or fiber cement, siding is an effective solution that can keep your home’s exterior safe and protected for decades.

Before starting the work, it’s important to diagnose what caused the stucco failure and determine how extensive the damage is. To do this, press your palms firmly on both sides of the hole or crack to determine how “springy” the area is. The springiness of the stucco is an indicator of how well the material was originally installed, and the less springy areas are more prone to failure.

If the stucco is sagging, this may indicate that the installer didn’t allow enough time for the underlying sheathing to fully cure, or the sheathing itself is rotting. A structural engineer should be called in to assess the situation and recommend appropriate repairs.

When removing damaged stucco, it’s important to keep the debris and old lath separate so that the new stucco can be properly attached to it. You can use tin snips to cut away the existing building paper or house wrap, but be careful not to disturb or rip any lath that’s still solidly attached to the existing stucco.

As you remove the stucco, keep a wheelbarrow on hand to haul the chunks away in for disposal. You can either load the pieces into your own truck or contact a local junk removal company to haul them away for you.

If the cracks in your stucco are only superficial, you can re-patches them using a premixed stucco patching product. Use a putty knife to apply the material, then finish it with a wire-bristled brush to add texture and match the surrounding stucco. If the cracks are deeper, it’s necessary to undercut the surface with a cold chisel to widen the bottom of each crack for proper mechanical attachment. This will also help the new bonding liquid “key in” to the old stucco.

Patch the Damage

Stucco is an attractive siding material for homes and requires little maintenance, but cracks can form. These should be patched to prevent rain from seeping into the wall and causing more extensive damage. Before deciding to repair or remediate, consult with a masonry contractor who has experience working with stucco to determine the extent of the damage and the proper method for dealing with it.

Start by cleaning the area around the hole or crack. Use a masonry chisel to remove loose stucco, working carefully to avoid damaging the lathing beneath it. Make sure to use gloves and eye protection during this process. After you have removed the damaged materials, check the lathing for damage. Loose stucco often bulges and feels spongey to the touch, while intact sections of the wall will give off a solid sound when you tap them gently with a wood or plastic hammer. If the underlying lathing is damaged, cut it away with metal snips and replace it.

If the crack is wide, you will need to make a larger-scale repair. While a pre-mixed stucco patch from your local hardware store can be useful for smaller patches, it will be cost-efficient to make your own mixture using the same ingredients as commercial products. Follow the directions on the mix package for mixing. To apply the patch, simply cut the nozzle of your caulk gun to match the size of the crack or hole and apply it in layers along the crack. Smooth the patch with a putty knife once it is dry.

A final step is to cover the patch with plastic and tape, so that it can cure undisturbed by rain or other elements. Alternatively, you can spray the patch with water periodically to speed up the curing process.

Once the patch is dry, you will need to apply a second coat of stucco. This will be the brown coat and it is important to smooth and level it well to match the surrounding stucco. It is also helpful to scarify the scratch coat with a trowel prior to application of the brown coat.

Apply a New Coat of Stucco

Stucco is a tough and durable material that can protect the walls of your home or commercial property. However, it can get damaged over time and requires regular maintenance to keep its good looks and prevent moisture problems. If you need to repair your stucco, a plasterer can apply new material in the proper way to ensure that it lasts for years.

Before applying a new coat of stucco, it’s important to make sure that all the damage and cracks are repaired. It’s also a good idea to do a complete surface cleaning. A pressure washer can be used to remove dirt and other debris. However, it’s important to use a low-pressure setting and to avoid using any features that spray water at high rates of speed.

You should also make sure that the underlying structure is in sound condition. This means covering the wood sheathing with a double layer of grade-D waterproof building paper and fastening metal lath to support the stucco. Then, you can apply three separate layers of stucco, called the scratch coat, brown coat and color coat.

If you’re patching a small area, you can skip the scratch coat and go straight to the brown coat. This should be applied in a thick layer, about 3/8 inch thick, over the base coat. It should be smoothed with a stucco float and allowed to wet cure for about seven days. During this time, it’s important to mist or fog the surface regularly to keep it wet.

Once the brown coat has cured, it’s time to add the final color coat. The color coat should be blended into the existing stucco with a stucco knife or trowel, and it should be smoothed and made level. The blending process may take some practice, but it’s necessary to avoid a noticeable line between the old and new stucco.

If you’re doing a complete coating, it is a good idea to add a sealant to the finished product. This will help protect it from the elements and prolong its life. When choosing a sealant, be sure that it’s alkaline-tolerant and permeable to water vapor. It’s also important to choose a pigmented finish that will match the color of your stucco.

Paint the Stucco

If you have an older home with a stucco surface that is looking dingy, painting it can make it look fresh and new. But before you start painting, it’s important to prepare the surface for paint. First, a thorough power washing is needed to remove any dirt and debris from the surface of the stucco. A pressure washer with a rotating nozzle is best for this, as it agitates the dirt and debris to clean it better.

Once the stucco is cleaned, a masonry caulk can be used to fill any small cracks in the surface of the stucco. Then the surface can be primed with a high quality acrylic primer. This type of primer has stronger binders than other types of primers, and will help the paint adhere to the surface more successfully. A synthetic brush can be used to cut in the primer, and a large napped roller will allow the primer to be applied easily into all of the nooks and crannies of the stucco finish. Once the primer is dry, you’re ready to begin painting. If you are using a stucco-specific paint, follow the manufacturer’s drying instructions. Otherwise, a normal exterior house paint will work just fine.

It’s important to apply the paint in thin coats. Trying to cover the surface with one thick coat can cause it to run or flake off. Taking the time to put on two or three thin coats will give you a more uniform surface and better coverage.

Before you start painting, mask off any areas you don’t want to paint. Use painters tape to protect any windows or doors that can’t be moved, and painter’s tape around any areas you don’t want to touch. It’s also a good idea to cover any plants or furniture that you don’t want to get paint on, or that might be damaged by a wet surface.

Although some homeowners are willing to take on the challenge of applying a fresh coat of paint to their stucco, this is usually a project better left to professional contractors. These professionals will have the experience and expertise to get the job done correctly, and will be able to recommend the right type of paint for your particular house.
