How to Patch Stucco

Your stucco walls might be bothersome for you if you see that it has cracks or holes. Even if it needs low maintenance, like other things, it will need a repair if it is damaged. Doing that will be pretty easy. Here is how you can do it.


Before doing anything, the best step is to inspect your wall first. Try and look at the damage and see its depth and how serious it is. Most stucco cracks are only on the surface and does not affect structural integrity. You may also look for holes that might not be too obvious, but also needs repair.

Repairing Tiny Holes

Patching holes in your stucco wall is easy, as long as they are tiny. That is why inspection is important, to see if you can do repairs yourself or if you need the help of an expert. You will need to prepare the following materials:

  • wire brush
  • caulking
  • caulk gun
  • protective equipment

To start the process, pet your caulking and cut the tip at an angle. Make sure that the opening is as small as possible, so it is easy to put it inside the hole. Before applying anything, clean the area first using a wire brush or blow into the hole to get rid of dust and debris inside. After that, you may load your caulking gun with caulking and fill up the hole. Check if there are gaps and get rid of them. Do not overfill the hole, just make sure it has enough caulking. Allow it to cure entirely. The caulking may shrink a little after it dries, but do not worry as this will work to your advantage. Apply a second layer of caulking and try to imitate the rough finish of the wall. After it fully cures, you may paint over it to hide the repair.

Repairing Hairline Cracks

Another common problem you might have is cracks in your stucco. They are quite easy to fixe. Here are the materials you will need:

  • Sponge
  • A bucket of water
  • caulking gun
  • caulking

Clean the crack first and the area around it using a sponge and a bucket of water. Remove any grime or dirt buildup that may affect the adhesion of the caulking. Dampen the area before applying the sealant. Next, you may fill the crack with caulking. Avoid gaps for a better job. Spread it evenly, and clean up the excess. Let it cure entirely. You may do another layer as the caulking might shrink, and you may use it to imitate the texture of the area. You will need to use a brush or sandpaper. Ensure that everything will have enough time to dry. With repairing cracks, the outcome might be too obvious, so you may repaint the area if you want. It is up for you to decide.
