Is anyone familiar with the Poly-bond material made by La Habra. I have a 1925 spanish house with a horrible looking exterior finish. Over the years, the previous owners have applied a rubbery-like paint that is now peeling along with a cement texture that seems to have been applied with a hopper. These textures, I have been told, will be next to impossible to sandblast off, according to several sandblasting guys I’ve asked. So, I called in a stucco company and they told me they can smooth out the exterior with a combination of Poly-bond undercoat with a top layer of fresh coat stucco. My question is, will the poly-bond undercoat create moisture problems similiar to what you find with synthetic stucco? Is this a common procedure? Any responses would be greatly appreciated.

I know not much about real stucco
With that disclaimer I will offer this.
You have a paint that is peeling off and I suggest that this might be indicative of moisture pushing it away from and releasing it's bond to the stucco beneath. Will the polybond do the same?
Who knows? But what we do know is that the new coat of Poly Bond won't do a thing to keep the peeling coat on your house. Ask the stucco contractor for his written, personel 20 year guarantee and watch him run. I wouldn't let anyone do that to my house for free. I'd say at a minimum you need well secured lath on top of your existing stucco then at least 2 top coats on that. The best fix would be to chip it all off and start from scratch.
