How to Repair Stucco Holes: A Step-by-Step Guide

Repairing stucco holes can seem overwhelming, but with the right tools, correct materials and proper steps, you can certainly do it yourself. Follow this easy-to-understand guide to repair your stucco holes or damages yourself!

Stucco Materials Needed:

  • Cement mix
  • Wire mesh / Fibreglass Mesh
  • Trowel
  • Hammer, nails, chisel and scraper
  • Sprayfoam ( FOR EIFS Applications )
  • Wirebrush or Other brushes with hard bristles
  • Paint brush
  • Safety gear (gloves, goggles)

Step 1: Assess the Damage

Before starting, examine the hole to understand its size and depth.

Step 2: Remove Loose Stucco

Using a hammer and chisel, gently remove any loose or damaged stucco around the hole.

Step 3: Clean the Area

Scrub away with wire brush, then brush away debris and dust using a paintbrush or a soft brush.

Step 4: Fill in with Spray Foam

Spray the foam to fill the hole completely. Be careful not to overspray. Skip to Step 5, if not EIFS.

Step 5: Attach the Wire Mesh or Fibreglass Mesh

Cut a piece of wire mesh to fit the hole, then attach it securely using nails or a staple gun.

Step 6: Mix the Stucco

Follow the manufacturer’s instructions to mix the stucco. It should have a thick, paste-like consistency.

Step 7: Apply the First Coat (Scratch Coat)

Using a trowel, apply the first layer of stucco over the wire mesh. This layer is called the scratch coat.

Step 8: Scratch the First Coat

Lightly scratch the surface of the first coat with a notched trowel to create grooves. This helps the next layer adhere better. Let it dry for 24-48 hours.

Step 9: Apply the Second Coat (Brown Coat)

Apply a second layer of stucco, making it level with the surrounding surface. Smooth it out with a trowel.

Step 10: Apply the Final Coat (Finish Coat) or Paint

Once the second coat has dried (24-48 hours), apply the final layer of stucco or paint. Match the texture to the existing stucco.

  • Work in cooler weather to avoid quick drying and cracking.
  • Always follow safety precautions, including wearing gloves and goggles.

By following these steps, you can repair stucco holes effectively and maintain the appearance and integrity of your stucco surfaces.
