Repairing chipped or cracked stucco is an easy project, but you'll need to set aside a few days to complete it.
Step 3: Apply the first coat of stucco Use a trowel to apply the first, or "scratch," coat of stucco. The scratch coat should be about 3/8" thick. Work the mortar up into the edges of the area to be patched. Let the stucco set until it begins to become firm, and then use the trowel to scratch a cross-hatch pattern of lines into the surface. This will form a mechanical bond for the final layer. Allow the scratch coat to set for 24-48 hours or until it is completely dry. Cut a cross-hatch pattern of lines into the surface.
