Made from Portland cement, sand, lime and water, stucco functions as a durable and versatile finish for exterior walls. As time passes, stucco could suffer cracks or chips as the house settles. The corners of stucco walls are particularly vulnerable to damage due to the chance of collision or impact. Repairing stucco corners not only helps to improve aesthetic appeal, but also keeps moisture to protect the home’s integrity.
Remove in the corner of the wall, with a hammer and chisel.
Evaluate the damage to the corner. If the corner bead is damaged or missing, cut a stucco corner bead to fit, with snips. Fasten it using galvanized nails. Alternatively leave it and proceed.
Open a container of premixed stucco and stir thoroughly. Stir in a small amount of powdered pigments to match your existing wall color, if desired. Pick pigments from precisely the exact same manufacturer as your stucco.
Spray the existing wall with water, with a hose. Alternatively, use a spray bottle to mist stucco walls with water prior to applying stucco.
A 1/4- to 3/8-inch coating of stucco to one side of this wall, using a trowel held . Until you’ve covered one border of the corner, work from the bottom of the wall to the top. Since you disperse the stucco toward the existing stucco to feather the stucco that is new into the old increase the angle of your trowel. Wait for the stucco. Repeat this procedure to cover the wall. Allow it to dry.
Employ a second 1/4- to 3/8-inch coating of stucco, using your trowel. If this coating has partly dried, then drag a plasterer’s rake during the damp stucco to make 1/8 inch grooves in the surface. The coat bond will be helped by these grooves .
Apply a final coat on among the two walls. Wait for it to dry prior to applying stucco to the wall to make a smooth corner. Hold your trowel at a 45-degree angle and also keep pressure for a smooth end. Adjust the angle and pressure of your trowel as you operate to make other desired textures and finishes. For example, allow your trowel to gently skip across the surface to make the traditional”skip trowel” texture. You might need to use tools such as sponges, rollers or combs to match your existing stucco texture. Consider swirling, twisting, rolling, skipping or dabbing these tools to make the desired texture.
Allow the stucco before touching the area, to dry. Consult with a premixed stucco bundle to determine how long to wait until paining. Some premixed products could be painted in just a few days, whilst stucco you mix yourself requires a complete month to heal prior to painting. Following the stucco has cured, use masonry primer and paint to paint the stucco corner that is mended to match the wall.
