I'm redesigning a couple of subdivision entrances that have brickwork that looks a little tired. I'd like to veneer cultured stone over the brick. Anyone here have experience with this?

With veneering over block, yes. Brick, no. That being said, I can't see how a good acid wash and scratch coat over the top wouldn't make this like any other veneer application.

I has the same problem a few months back where I was asked to veneer over an inside fireplace made of brick. Although the project never amounted to anything , I was concerned that the type of brick I was up against wouldn't hold my scratch coat well enough. Some bricks have a smooth surface while others have a "gritty" feel where you can almost rub off particles of the brick , like a fine sand.
Since I had these concerns, I figured the only way to warranty my work was to screw a metal lath onto the brick and then apply my scratch coat.
Maybe someone else on this site has done this application before and can shed a little more light on this subject.
I would try it on my own house but to do a neighborhood entrance without knowing the best application might be a bit risky.

I'd love to do that to the front of my house. but I am thinking It maybe best to remove the brick. Other wise the build out would be to thick

But then what do I do about the brick around the rest of the house?

Had the house resided before Xmas.........stone would look so much nicer than the brick...........if you or anyone does the stone over brick......be great if you can take pics and document the work

I've got a note in to the folks at Owens-Corning, the makers of Cultured Stone. We'll see what they have to say.

Thanks for the responses.

I bid a job recently, and we decided to tear the brick off. Mainly because if we adhered the stone to the brick it would stick out too much at the window sill. I like Fine's idea w/ screwing in the lathe.

I have recently completed a job similar to this, it was for an indoor fireplace....although I'm sure screwing metal lathe to the bricks would work just fine, the method I chose was to screw cement board to the brick...turned out well, and I'm sure it will hold up just fine

[4seasons]

when using cement board do you have to tape the joints or smear mortar?

[bricknblock]

just apply a scratch coat over the cement board, it's also a good idea to lightly dampen the cement board prior to the scratch coat to ensure it cures properly

I haven't heard from Owens Corning. (And I wouldn't hold my breath.)

Just got word back from Owens Corning:

Clean and untreated face brick requires no preparation prior to installing Cultured Stone. However, if the face brick is dirty, painted or sealed, sandblast or waterblast to the original surface (remove sandblasting dust by washing) or securely attach lath.

That's good to know. Thanks Jeff!

I always pressure wash any masonry wall before I apply stone veneer a clean surface is always the best way to start. Untreated brick and block and stucco just wash and go. Any painted or stained masonry surface I wire lathe and scratch coat first then apply stone. If I am going over plywood first I cover the wall with moisture sheet (tar paper, tyvek) then wire, scratch coat and stone. I like to use a matte water seal over the plywood systems to be safe. I offer the sealer to all my customers the matte doesn't affect the color to much. I like to spray one stone with the sealer at the begining of the job to show the customer so they have the option and can see the color change if any.

KWS - that's a good idea - additional protection for the plywood.
