Genius! Such a simple solution to such a big headache. Drilling through stucco is just no fun, and then there's caulking that dries out over time and then i worry about any water damage that could result from water seeping into the hole. Thank you. Great video. And I like how you actually left a reply for all the comments.
Good question. Honestly, if the surface is smooth and clean, command strips alone should work fine. I have some around my garage door for 4 years now, no issues, but it's painted plastic trim. Well, at least I think it is. Let me check.
I'd take a brush beforehand to clear away any really, really loose stucco. Not a stiff wire brush, I'm thinking just a broom. Depending on your paint condition, the CA glue might stabilize the stucco enough for the clip to hold. My paint is recent, so the CA glue doesn't penetrate. If your paint is older, enough glue might make it's way in to hold everything together. It's amazing how much one drop can hold.
