Help ID'ing A Product...Do You Know What It Is?


I need to do a repair to this wall. I've never seen this product before. It appears to be a faux concrete finish. It is trowled smooth with small areas of imperfection. It is a newer home and the finish is over sheetrock. Any Ideas?

edit: This could be applied over cement board...I'm not sure if it matters or not.

Normally over sheetrock it's a plaster finish layer.

Any ideas of what kind of plaster I'm dealing with?

I would do it in drywall and joint compound. Matching the texture is going to be the tricky part, so practice on some scraps.

The texture is pretty much smooth, I just don't know what material to use as the top coat. The walls aren't painted, they appear as another poster stated some sort of plaster. I'm just not well versed in all of these finish materials. So I'm trying to ID what it is.

I would say that it is exactly that, plaster, plaster of Paris to be precise. Probably over blue board. They may have added a base tint to also.

The next thing to do is figure out how many coats at what thickness was put down. There's a good chance it was a single coat ~ 1/8" thick. Like Andy said, over blue board. The thin ones like that are called veneer plaster.

Lots of this is done down in Massachusetts. Pretty much a special order product around here, but Home Depot stocks Diamond veneer plaster.

You can probably ignore all that, I don't know if you can do that decorative work with something like Diamond.

Getting a decent final match is going to be a sumbitch.

That would be a time to pass it off to a plaster guy.

I'm a sucker for trying new things, but that looks like a nightmare.

Funny thing about random patterns or plaster wash like that. It is never really random and what you do will stick out like a sore thumb.

The only saving grace is it's on the ceiling. I counted at least 3 layers of color. The only guy I knew who could nail that type of work was a mural artist who did all kinds of decorative finishes to make a living.

He'd have to make up some panels and see what got him a match before doing the patch.

Re: Help ID'ing A Product...Do You Know What It Is?


you do not need to be very concerned with the product as the end results.

you have encountered a texture/wall finish done by a local artisan or a travelling one.

how the product is prepared, tinted, applied etc are very often like trying to copy someone's handwriting.

unless you are EXTREMELY skilled at matching hand textures it would be best to find a local guy who can attempt the match.

good luck.

Re: Help ID'ing A Product...Do You Know What It Is?


The best thing is to convince the home owner that the place looks like a great big pile of ****, (which it does). And to renovate nearly the entire thing into something that looks good and has a classy timeless style, (which this does not).

It is a ridiculous, foreboding torture chamber looking house of horror. And that is just the good parts.
