Wall/Stucco Repair

[noluck24/7]

Not sure if the pic will show but...

I recently had an old wood patio cover removed and the part that was bolted to the wall left behind multiple holes in the wall and stucco. The guy I had haul everything away had previously said that he could fill any holes that would be exposed once the cover was removed. When it came time to fill the holes the guy grabbed a tube of silicone and was about to fill the holes. I stopped him and told him there had to be a better way and that I'd take care of it.

So, what is the best way a DIYer can repair these holes? If the pic doesn't show, it's of an exterior stucco covered garage wall and some holes lead into studs and some just go into the hollow space of the wall. Please help before the rain starts. Thanks.

Can't paint silicone. Caulk holes with DAP dynaflex 230. Paint it up and you're done.

There are paintable silicone caulks. Stucco is not a place to use non-paintable caulk.
I have never found a DAP product that has not disappointed me in one way or another.
Latex caulks shrink a lot. If you fill the hole level, expect it to form a dimple when it dries, and crack in a few years.

Me, I'd just stick some stucco patch in there with a putty knife.

Couldn't you "pipe" in stucco patch like a baker? Use the cake decorating bag and fill nozzle.

You can, but while real stucco is concrete based, the stucco patch that comes in a bucket is latex based. If you fill the hole too deeply, it will cause cracking as it shrinks.
You could use a foam backer rod, or just not overfill it.

Oh, and you don't need a cake decorating back to pipe stucco. Just a freezer zip-lock bag with the corner snipped off. It's all in how you grip the bag.

I had to match a stucco wall in my old shop where I walled up an existing door with a drywall finished. Not wanting to run to the store and go through the whole stucco mess, I came up with a rough fix. I first painted the wall wet with latex paint and then threw kitty litter at it (keep kitty litter for oil spills). It stuck but wasn't quite thick enough. Then I mixed in a bunch of kitty litter with some latex paint and rolled that on. It matched amazingly well.

I would patch those holes with some standard wall patch putty first.

Some good info. What about the holes in the plywood under the stucco? Should I plug holes in the plywood under the stucco with a dowel and glue or something and then place the stucco patch on top?
