In my father-in-laws basement, there is an interior concrete block wall I am considering skim coating. By interior, I mean both that it is inside the basement, and that it does not have soil on the other side (i.e. it is a wall in the middle of the basement).
The wall has been painted in the past (at least 20 years prior), the paint seems to be adhering well. If there is a product that would allow me to skim coar it easily with a total coating thickness of <.25″ I would very interested. I was thinking about quikrete “surface bonding cement” (dry stack block stucco), but I’m not sure if it will work on a painted blocks… I’ll call them monday to ask.
Anyone have comments on if this would work or a better product to use?
Thanks
Erik

Dino here came up with something he calls D-mix. It has PVA primer, joint compound and plaster of paris in it. He mixed it up till it was the right consistency, which is kind of difficult to know if you never used it before.
Go to advanced search, type in dmix or d-mix.
Here's one http://forums.taunton.com/tp-breaktime/messages?msg=59185.2
I was told by a plaster guy that he would never plaster with any product right over block.
He said the mortar lines would show up over time. He suggested putting paper and mesh on first.
But I think he was a real stickler and old school.

"He said the mortar lines would show up over time. "That's because he's absolutely right.
Hmm... d-mix sounds interesting... anyone ever use the quickrete product?
Thanks

I would not expect it to hold to paint. Perhaps texture paint would work. It can be troweled smooth if you get the fine texture.
If your talking about the quickcrete product called
quickwall, a good friend has been using it on block
wall for a rather nice fountain. Great stuff, looks
fabulous and time will tell how it wears. But so far,nice to work with. And can be waterproofed with one of thier other products, can't remember right now. BeckRe-Home Solutions Inc.
Been years since I used it, but there used to be a heavy-weight, textured wallpaper that was just for that situation.
It was similar to a bridging paper that you would use to go over rough or cracked walls prior to the finish wallpaper - but in this case it is intended to be painted over.
I used it to cover up rough surfaces to end up with something both economical (cheap) and a good looking finish surface.
I use to put it up over old paneling that was put up by a HO as a repair over bad plaster, block wall in basements and on walls that plaster or drywall was shot.
It was prepasted, the paper was tough and covered a multitude of sins. Painted to match the rest of the room, it looked like a textured wall without telegraphing the defects in the covered surfaces.
Borden was one manufacturer of it. Not sure if it is still available. Always bought it through a paint/wallpaper store.
