Wife and I pulled out a wall A/C unit this weekend. I used drywall screws to fasten a combination tar paper and wire mesh product in the hole. I mixed up some stucco patch and troweled onto the wire mesh. Now that the scratch coat is over 48 hours old, it is shines like it was painted with a high gloss paint. The rest of the wall is not glossy at all, and I have another A/C unit to remove on the same wall. How do I make the final coat not shine?

Are you going to apply a Stucco Mix as your last Coat? It should not be shiny . If your going to apply another Base coat type mix then give it Sand finish. Rub it with a Sponge Float or even just a Sponge it will expose some sand taking away the glossiness of the hard Troweled Cement.

This coat is the first, I scratched it and plan to apply one more coat and then a finish coat because I read that's how it is done. If you know differently, please let me know. Is it OK to use the stucco patch product on all three coats? I like it because it's so easy to just add water.
By the way, does it matter if one edge of the tar paper caved in because it wasn't fastened to the wood 2 X4 and a bunch of stucco is now touching the stud? I can see the back of the paper from the inside of the house and there is a big bulge on one side of patch. I will take it out and do it again if it matters.

I'm not sure on the product you are using. Is this a Base coat material? The Scratch Coat is liable to have a Shiny appearance if it was just Hard Troweled and then Scratched with some type of "Comb" or something.
The Tar Paper serves a few purposes. One to protect the Lumber from any moisture that can build up behind the layers of Stucco. Another is to protect the Lumber from the Cement materials. Cement can cause Wood to rot prematurely over time. So if it was me and my house I would be sure you're protected from these elements.

Thanks Mortarman,
I used a wood float to trowel the patch material in the hole. Here is a link to the exact product I used from custom building products, it is called "Stucco Patch".

About the tar paper mistake, I did not want to hear that I have to pull it out and do it again, but you made a good point. Before I pull out my hard work, does it matter if only about two inches of the stud are in contact with the stucco, about an inch deep? I hope your answer is no, but I want to do this right.

Stucco Patch is different from regular stucco mix. The Patch contains it’s own glue which helps it stick better as a repair. From my understanding the Patch can be applied without base and scratch coats, and doesn’t have a limit as to how thick it is applied.
Perhaps it is the glue that gives it a shinny appearance when dry. You should prime and paint after patching so the shinny surface shouldn’t be a factor.
From personal experience I have laid it on VERY thick and it has formed cracks occasionally. I believe part of the trick is getting the right amount of water. Also with heavy coats on vertical surfaces there is a tendency for it to sag when mixed with the proper amount of water. So layers are better.
