How to Patch Spanish Stucco

Remove a 2-inch section of stucco around the affected area with a hand-held chisel. Cut the stucco away until the tar paper underneath is exposed, paying attention to not damage the paper.

Clean the area with a wire brush to remove any loose dirt, debris and smaller pieces of stucco.

Mix the stucco for the patch according to the package directions. According to This Old House, stucco is also created by mixing together three parts sand, one-quarter part lime and one part Portland cement mix.

Continue to mix the stucco until it reaches a peanut butter-like consistency.

Tint the stucco with a mortar dye, if the stucco is not painted. Otherwise, skip this step if the final product is to be painted to match an existing color.

Wet the affected area with a garden hose and apply a thin layer of the stucco with a trowel. This coat is applied thinly to provide a base to support the weight of subsequent coats.

Allow this first, thin layer of stucco to dry before again wetting the surface with the garden hose and applying a second coat. The thickness of the second coat will depend upon the existing stucco finish on the surface. For instance, Spanish-style stucco that was originally applied thickly requires a thicker second layer of stucco. According to This Old House, a wet rubber float is then used to spread the second layer of stucco into the surrounding areas to create a more seamless finished appearance.

Allow the second layer of stucco to dry completely before covering it with a layer of primer and paint, if the surface was originally painted.
