How to Repair Stucco
Repairing damage to exterior stucco walls is not very difficult, and can be accomplished by a novice as well as an expert. Working with cement and stucco may be intimidating at first, but just remember that if you make a mistake, you can ‘erase’ it by spraying with water before it dries and start over. No pressure! Here’s how to repair stucco:
To repair large holes in stucco, you’ll need to purchase a bag or two of exterior stucco mix. This mix usually comes in about 50-pound bags, but in some hardware stores, you can find smaller bags. All you need to do is add water, but follow mixing directions. Some people like to add adhesive to their stucco mix, so ask if you’re not sure. You can mix the batch in a bucket or a wheelbarrow or a plastic tub. Make sure that your mix is not too dry, but you don’t want it runny like cake batter, either.
How to Repair Stucco -Chicken Wire
Make sure you can see ‘chicken wire’ in the to-be-patched area, or insert a square yourself prior to patching. Anchor the piece of ‘chicken wire’ to any exposed 2×4 framing with stucco wire nails. If no 2×4 is exposed, wire edges of new wire to existing edges of existing pieces of wire already in place behind stucco. This will allow the stucco to adhere to something while it dries. While this process is a bit more complicated than repairing minor cracks and small holes, it is also rather simple and can be accomplished in a short amount of time.
- Mix stucco mixture according to directions on bag.
- Apply a coat of stucco mix using a stucco or rubber based trowel, using half circle motions with your wrist. At first, you may find that more stucco ends up on the ground than on the wall, but practice makes perfect.
- Fill in the patch area first, bringing stucco to the very edges of the repair area.
- Go over the entire area with a water-dampened trowel. Try to maintain an even coat, sweeping from existing wall to area to be patched. Extend the new stucco past the edges of the repair area in a sweeping motion.
- Again dip your float into a bucket of water and gently smooth the surface of the patched area, again sweeping past edges and onto existing stucco to create a smooth, unbroken surface.
- Look at the patched area from different angles to make sure that your new surface is flat, and has no dips and bulges. If you see the patched area sagging, sweep the float in an upward direction to remove some stucco and wait for it to dry a while.
- With a wet float, go back over the area several times as it dries. As the stucco dries, it will turn a light gray. Keep working it as it dries, though be careful not to get so wet that it starts to sag again.
Repairing stucco is not difficult; a little patience is required, that’s it!
