Full Wall Slabs

[Scooter]

We are installing 50x120 slabs of travertine on the walls which are concrete what do you guys recommend we use to glue them to the walls?

[Ken Lago]

Laticrete Platinum.

You could also use Rivo50 for strong bond.

It is good for indoor/outdoor applications too!

I know this is not answering your original question, but it could be helpful.
If those pieces are 2cm, they will probably weigh over 500 pounds. We are about to release a new handle for our vacuum cup Sink Hole Savers for lifting wall slabs vertically. If you think this might be helpful, give me a call!

Very helpful guys do you think i should use some kind of anchoring for this application or would the epoxies mentioned be enough?

[Ken Lago]

Depends on what the specific situation calls for.

Epoxying directly to concrete walls could raise several issues.

Your climate is in a freeze thaw area, so the movement differences between the concrete supstrate and the marble could cause cracking issues.

Concrete walls are never as plumb as finished walls need to be.

The job should have anchor specs in the plans. If they do not and you "wing it", then you are on the hook for any installation issues, forever....

120 x 50 is a pretty large slab for vertical application. Who specified those (owner or designer is my guess and not an engineer) These slabs should be considerably thicker than 3 cm, for the required tencel strength.

Your question sounds like you may be a newbie to this type of stone work, imo. While this is not overly difficult, there are a lot of factors that need to be considered and addressed. I suggest that you address them, BEFORE you begin the project.

....120 x 50 is a pretty large slab for vertical application. ...

That's what I was thinking. But at 3cm, these start to approach 800 pounds.

We would anchor using a good modified thinset and tie in with wire. If there is mesh on the back it must be removed. We are wrapping up a 16 slab fireplace right now. Thinset and wire.

Nothing wrong with copper wire.
The Romans used it extensively, and the last time I saw the Coliseum it looked pretty good, for it's age!

[Todd Luster]

Are these 120 tall, or 50 tall?

Either way, I would certainly recommend anchors as mentioned.
We typically try to follow MIA specs on these type installs, which would fall under the vertical surfaces for this.http://pubs.marble-institute.com/resour ... mpleSearch All these documents are offered free and there is a link attached and you can also find the other in their room here..
Depending on the situation we might do copper wire anchors and plaster and add spot sets of thinset or Rivo/Latapoxy 310.
If it has fiberglass and it's well intact, I'd probably use epoxy for spot setting to avoid having to remove it.

and Dan was there when they installed it!

+1 for adhesives plus anchors. We have our Keep-nut anchoring system, which will work whether the slab is 2cm or 3cm. These are very strong blind anchors that are easy to install. Here is a photo of a job one of my customers recently did. This a large stone panel that will have beer taps mounted to it at a bar.

We also have some very strong industrial epoxies that would work great. If the mechanical anchors are doing most of the work, you could go with a flexible 1 part adhesive. Our MS35 adhesive is 3x stronger than silicone and will not stain natural stone like some urethanes do.

Let me know if you want any more information on this. Hope this helps.

Ive had the same question on mounting a slab to a concrete wall. Couldn't the slab be mortared to the concrete? Or would mortar not be strong enough? Would mortar expand at the same rate as the stone?
