How to Patch Stucco Hole

How to Patch Stucco Hole

Stucco is a popular material used for home exterior and interior finishes. It is durable, long-lasting, and fireproof. It is made of cement, sand, lime, and water, and is meant to add texture to surfaces. 

Adding a layer of stucco to your walls or ceilings will surely spice up your home. However, as it is always outside, exposure to weather and pollution is a factor that will give you some problems. Your stucco may have holes that you need to repair or patch up. Here is a guide to help you with that.


Before doing a project, you should always grab or prepare the materials and tools first. You will need a hammer, chisel, trowel, snips, drill and beater, scoop, float, tape measure, and hammer tacker. Other than these tools, you will also require safety equipment like gloves, dust mask, eye protection goggles, and clothes suitable for the work. You also need materials like Double D tar paper, cement mix, tape or covers, lath, bonding agent, and water. 


To start the repair, go over to the damage and cover the area around it. It is important to protect the other parts of the wall from dust or cement that you may have during the process. You may use cloths or tarps and seal them in place with painter’s tape. Then, wet the wall and use the hammer and chisel to break the damaged part (stucco and lath) off the wall. Pull back the old metal lath to easily manage it. Measure the part uncovered by lath, cut a piece of double D tar paper with the same size, and staple it in. Next, you have to use a rubber membrane and some staples to seal the outside edge of the lath. Cut a piece of the new lath you have that will fit into the area. Use a few nails to keep it in place, nail it in, and make the old lath you bent overlap with it. 

Next, get your cement and patch over the lath. Scratch the first layer and let it dry. Then, you may apply the brown coat evenly. Put more cement and level the area using a darby. You may use more to make sure that there are no holes. Level it once again, then use a wet float to rough the surface. Apply more pressure around the edges to even out the area and make the match blend with the surface. Let it cure fully, then, you may put a final coat of paint.

After repairs on stucco, most homeowners will choose to repaint the whole area, so it will blend in better. Using an identical color to paint over a small area may not work, especially if it is already dull and a fresh coat will significantly look brighter.

Stucco may be low-maintenance, but like all aspects of your home, it will need repair when damaged. Make sure that you will take care of a problem once you notice one, to prevent bigger ones.
