Just like everything else in the world, there comes a point in time where your stucco is in need of repair. It might be a small patch or an entire wall, it really doesn’t matter, what matters is how you intend to fix it.
Fixing Stucco Yourself:
It is possible to fix a small patch yourself, I wouldn’t recommend trying to repair an area larger than 10′ x 10′, these types of patches come with a lot more variables and can be more hassle than it’s worth for the average homeowner.
- Step 1: Take a hammer and gently hammer away at the area where you are going to do the patch. You want to keep the paper and wire in good shape so you will be able to tie in to it later. The area around the patch should be inconsistent, you want to avoid straight lines, they will show evidence of a patch, so the rougher, the better.
- Step 2: Remove any nails or staples that remain, but keep the paper in tact as much as you can. You want to keep about 6″ of paper and wire around the area to tie in the new paper and wire.
- Step 3: Cut a new piece of paper the size of the patch and staple it to the wall. Use only as many staples as you have to, the fewer, the better and make sure you tuck the paper in at the top and overlap it at the bottom. Water will flow down the wall, so you want it to run down the paper and not get behind it, look at the paper and determine if it will repel water properly.
- Step 4: Caulk staples and areas the the paper is not overlapping enough (usually at the bottom of the patch, where the new and old pieces meet).
- Step 5: Cut the wire and nail it on where the studs are and around the patch, try not to nail through the plywood, if possible. Caulk all nail heads or staples and let dry for a few hours.
- Step 6: Apply the mud at a thickness of 3/8″ and score the mud with a notched trowel or a “scratcher”. This is a base coat for your next coat, so it will need to be rough to promote proper adhesion. Let the mud cure for a day or two, watering it twice a day, in the morning and evening to make sure it properly cures.
- Step 7: A second coat is applied and should be flush with the existing stucco. Let it dry a little and then GENTLY scrape the patch to get an even, uniform pattern. Using a hard rubber float, pack the surface using circular motions and swirling the still workable patch. Be sure the patch is a little (1/16″-1/8″) indented, meaning it should not be flush with the existing stucco. You want to allow the top coat to blend in properly, so make sure you do not fill the patch too full of mud. Let the cement cure for at least 7-10 days, watering it twice a day for three consecutive days.
- Step 8: Apply a finish coat and match your existing texture on the area. Feather out the edges and make sure there are no lumpy spots that will stand out when it dries. Let the top coat dry for a week before painting. That’s it!
This is a brief overview of how to do your own stucco repair yourself. It is pretty simple and requires minimal tools.
