Stucco on poured concrete walls
 
1 Attachment(s)
Have just finished hanging all the metal lath on my painted poured concrete walls. This is in my basement. The guy who will be doing my stucco said he will use only two coats, brown coat and finish coat. I have read that when applying stucco over lath you have to use three coats,scratch, brown,then finish. Any ideas? The walls are painted. They have a stamped brick pattern and there are voids that will need to be filled in.

2 coats should be fine for that application.

In your case, 2 should be fine. I just had the stucco done on my house...the last coat is actually called a color coat and is really nothing more than about an 1/8" layer of stucco with the color applied.

I'm assuming he is going to give you a smooth finish....

Okay. Base coat is done over lath. Looks good. In a couple areas I noticed it seemed to dry quicker. I noticed a horizontal stretch about two feet long that was lighter in color. When I tapped my finger nail it seemed to have a ting to it. Seems to have a void behind it. There are only a couple areas that seem to do this. Is this normal or should I have my stucco guy look at it before the finish coat.?

Unless you expect the wall to get a lot of abuse...I wouldn't worry about it. Your second coat is going to add more thickness...so I'm sure it will be plenty strong.

Okay. Stucco is up and looks great. Next step is sealing. I would like to use a good penetrating sealer that will also breath. I've been looking and many of the breathable sealers say not recommend for below grade. Does this mean exterior below grade? Any recommendations?
