I have an exterior stucco wall that appears to have been painted. I would like to somehow remove the paint to expose the rough surface of the top coat so I can limewash it.
I tried scraping at it with steel and brass wire brushes but they produced a result I was not expecting: the wirebrushed area became smooth and metallic.
Is this the right approach? What is the right way to remove paint from stucco?
Update: I contacted several sandblasters and they all say it's not worth the trouble, as the blasting would likely destroy the stucco, necessitating a whole house re-stucco, in which case it would make more sense to simply screw wire through the existing stucco and apply a new layer without the added expense of sandblasting.
Are there any chemicals I could use to strip this paint? Or am I really going to have to get the entire house re-wired and re-stuccoed? It seems like such a shame since the substrate beneath the paint is really just fine.
