I looked at a home tonight where the HO pressure washed the shingles of their tudor home and the pressure “broke open” the wall surface some exposing the MDF siding. I say “siding” because the exterior of the wall is composed of 4’x4′ MDF panel, at least it looks like MDF.
Anyways..the MDF is disintegrating resulting in increasing failure now of the wall surface. Over top of this MDF is something…sorta like Dryvit? But it’s not. It’s more like a very heavy layer of latex paint, but the paint is textured to look like knockdown on drywall finishing.
Confused yet? I”m trying to figure out if it really is MDF I”m looking at, and…..what the surface covering is. I need to remove 5 of these 4×4 panels and replacde them and need to paint/texture to match the rest of the home.
Anyone ever heard of this?

If you could post a pic I'm betting you'll find out.

This is purely a case of alien identity
There was such a beast around a few years ago, but I thought it was an MDO panel. I am not sure who manufactured it, but GP comes to mind.
It was used on the Tudor stile homes as a faux stucco look. Earlier versions were over tempered hardboard, but it had such a high failure rate they got away from it. Depending on the age of the house, you may have the hardboard version.
The stuff was junk. Typical hardboard failures with edges swelling and the finish peeling off. You will likely find some water dmage behind the stuff when you take it off.
Good luck with this one.

I think you may have hit it, this seems like what you're talking about. What is a good replacement for this stuff? What is MDO vs. MDF by the way?
It sound like stucco board to me. Yes, Virginia, this is garbage.I know you asked Dave, but I think the Hardi products are excellent (fiber cement panels/boards). Don't know if you can find a matching pattern. If you replace it all, it does not need to match!MDO is Medium Density Overlay, a panel of usually veneer-core plywood with a heavy layer of smooth paper factory bonded to the face. It is used a lot for concrete forms and signage.MDF is Medium Density Fiberboard, which is a panel made from very small wood fibers and glue. It also has a smooth face, and is available in an exterior version.Bill
What about using fiber cements panels. They make them in several "stucco" patterns.
Bill....where can I find 'em, the fiber cement panels in a stucco look? I confess, never saw them before anywhere.
Hardie (Hardy) and Certainteed both have 4*8 (4*9) sheet panels in different patterns.Check there websites to see which patterns they have and for the dealers.I think that there are a couple of other FC brands around, but those are the 2 biggies.
To me the coating sounds like Texcoat, a sprayed on film from '60s-70s that was supposed to be impenaratable, but failed miseribly.
Lots of class action suits ect.
It was put over anything because it was failsafe. Used in new constrution and also sold like vinyl siding.
In the late '70s I made alot of money installing siding in a neighborhood that had a large settlement against the builders.
