5 Steps to Repair Stucco at Home

Step 1: Clean the area

Before beginning the exterior stucco repair work, make sure to clean any dust from the cracks or holes in the stucco using a brush or shop vacuum and remove the crumbling stucco. Remove loose pieces of stucco using a hammer or with a hammer and chisel.

Also, be careful not to damage the lath underneath. Before proceeding with the repair, allow the stucco to dry completely. This is done so that the new coats you apply go in smoothly.

For this step, it is recommended to use safety glasses to avoid getting hurt. Because, while removing the damaged stucco, there is a possibility that debris could get into your eyes. For this reason, it is recommended to get protection first.

Step 2: Prepare the repair area

For a successful repair, you need to prepare the area. Regarding smaller cracks, use a putty knife to widen the crack and create a V-shape. This helps the repair material to stick to the stucco more effectively.

In case of larger holes, use a circular saw or reciprocating saw to make a square or rectangular shape cut around the hole. This will provide a clean and straight edge for the repair material to stick to.

Step 3: Mixing the repair material

There are some different options available for repairing cracks or holes in stucco. The most common among them is the stucco patch. To use it, simply mix the powder with the water in accordance with the instructions mentioned in the package. Regarding larger repairs, you may find the need for premixed stucco repair mortar or a traditional mix of Portland cement, sand, and water.

Step 4: Apply the repair material

Mix the repair material and apply it to the crack or hole using a putty knife or trowel. For smaller cracks, fill the crack completely and smoothen the surface with a trowel. In the case of larger holes, you need to apply several layers of repair material, allowing each layer to dry before applying the next. Make sure to follow the manufacturer’s instructions about drying and curing times.

Step 5: Finish the repair

Repair is completed when the material has been fully dried and cured. For small cracks, smooth the surface and blend the repair material with the surrounding stucco using a sanding block. For larger holes, apply a coat of stucco finish to replicate the surrounding wall. To do this, mix a batch of stucco finish in accordance with the instructions mentioned in the package and apply it to the repair area with a trowel or a brush.

Follow the manufacturer’s instructions regarding drying times and curing. If the repaired part is not pre-painted, you will need to paint it to replicate the surrounding stucco. This ensures that the paint sticks to the stucco and creates a more even finish.

After the primer is dry, apply a coat of exterior paint using a brush or paint. If you are not sure of the stucco colour, just take a sample of it to the store to have them match it for you.
