DIY steps
- Before starting, ensure your safety by wearing protective gear, including gloves, safety glasses, and a dust mask. Turn off any nearby power sources and cover surrounding areas to prevent damage from debris or stucco mix.
- Clean the damaged area thoroughly with a wire brush to remove any loose or crumbling stucco. Use a damp sponge to wipe away any remaining debris, and let the area dry completely before proceeding.
- Apply a bonding agent to the prepared area, following the manufacturer's instructions for application and drying times. This will help the new stucco mix adhere to the existing surface.
- Mix the stucco according to the manufacturer's instructions, and apply a scratch coat to the damaged area using a hawk and trowel. Hold the hawk at a 45-degree angle and use the trowel to spread the mix evenly, feathering it out towards the edges to blend with the surrounding stucco.
- While the scratch coat is still plastic, score it to create mechanical keying for the next coat. Cure it according to the manufacturer's instructions; do not smooth away the keyed surface.
- Apply additional coats of stucco mix as needed, following the manufacturer's instructions for application and drying times. Use a level to ensure the surface is even and plumb, and a straightedge to check for any imperfections or unevenness.
- Once the final coat is dry, use a wire brush to remove any excess material or imperfections, and apply a finish coat of stucco mix if desired. Allow the finish coat to dry completely before sealing or painting the repaired area.
