Stone Veneer

[Gruneun]

Has anyone used cultured or manmade stone for the outside finish of their ovens? We're in the process of building a new house and plan on using a stone veneer on the exterior. I was wondering if there were any potential problems with using a matching finish on an outdoor pizza oven. The same product is used on the exterior of fireplaces and chimneys, but thought I would check here.

Thanks,
Brian

I don't see any problem with using a cultured stone finish product. The only place where your oven gets a little hot that might touch the finish material is at vent landing. You could either build a brick or stucco arch around the vent landing, or use the cultured stone there. Everywhere else, the finish walls are fully insulated from anything hot with lots if insulation.

I know of at least one other builder using a cultured stone, and could put you in touch with them iif you are interested.

Brian, I am using Cultured stone over concrete backer board. Primarily to save weight, and cost - plus it is the same stone I that is on the facade of my house. I do not think you will have any problem if you use it.

Great! Exactly what I wanted to hear.

Thanks!

I am planning stone veneer finish over cement or concrete board (permabase). Do I need to waterproof the board before attaching the veneer or will the mortar take care of that? Permabase says it is impervious to water but it is not a water barrier.

Also, any ideas on where I can find roofing that looks like authentic tile but is easy to install?

Thanks.

Fred,
I would use the recommended mesh tape on any of the concete board seams along with a fortified thinset mortar. Then use the same fortified mortar for installing the stone veneer. When properly trowled (spread with the smooth side first, then the notched side) it will seal the surface under the stone.
