Though you’re better off leaving major stucco repairs to a mason or stucco specialist, you should be able to handle fixing minor holes or cracks. Repairing a hole in stucco calls for cleaning out the area and apply a new patch of stucco mixture.
To patch small holes (less than 6 inches wide), you don’t need to layer stucco as if you were applying new stucco to the house or repairing a large whole (See “Stucco Siding: Repairing Large Holes”). You can simply pack the hole with stucco patching compound.
