I have a client who wants me to install cultured stone on their stucco house. What is the proper way to do so?

We want to stucco the section by the secondary front door, Main section by the front door and the section of the house all the way on the right.

Remove stucco & install cultured stone per manufacturers specs

If it isn't painted scrape any loose stucco off. Score it up a bit. Parge it with mortar with glue and thinset added to it. It ain't the "Right" way but it will work well. Try and pull the stone off after a couple days and the stucco including basecoat will come off with it before the bond breaks. Trying to remove the stucco will be a big mess and is an unnecessary risk of damage to the structure. I've even gone over paint with the mortar thinset and glue after scoring it up. It isn't "the right way" but it's time tested and it works.

Before you do anything, read the JLC cover article from a few months ago.

Apparently, following the manufacturer's specs isn't going to get the job done. If you follow the author's recommendations, you can install it according to someone who rips out and reinstalls according to the manufacturer's AND the re-installer's specs.

I have a friend with a set of apartment buildings with the stuff installed according to the manufacturer's specs. You don't want to be around there when it rains.

All I know is to build it to code & manufacturers specs, I, as a contractor am off the hook on warranty issues. I take lots of pictures before, during and after construction.:thumbsup:

Sounds like your client was watching the DIY shows on Saturday and thinks you can just stick this on the house & be done with it.

Educate them on the details it takes to make the window & door casings work and how to flash this added layer to keep water out of their home.

That should help you price it right.

It is possible that monkeys will fly out of my ass. It is not likely, however, and the chances of a successful application of cultured stone over painted stucco using that method are about on a par.

From your previous posts, Ruskent, I get the feeling that you perform quality work. Remove the stucco to sheathing and start over, paying close attention to flashing details per manufacturer recommendations.

Tscarborough whats the best way to remove the stucco? I'd rather remove the stucco and its only 350 sq ft total. Without using the teeth on my excavator. Where is the best place to get a good overview on the flashing?


I know how to do the stone work. I just don't want to past this job up because its on a house instead of CMU wall.

You can cut the stucco and pry it away. Often the paper comes off with the stucco. The problem remains that when you repaper without removing additional stucco you won't get a proper lap. If the paper doesn't come off with the stucco it usually ends up full of holes and needs to be replaced.

It would seem easier to remove the EIFS without destroying the membrane behind it, if there is a membrane. I believe a membrane was added to the details in 97'. Not sure. I've really never dealt with it. Reading up on it the problem with it is that it traps the water against any sheathing and would have to be repaired properly using proper adhesives. That's a whole other can of worms. I don't know.
