River rock tile on brick surface...

Savela

I'm a newbie so go easy. I'm hoping to install some pebble river rock tile (stones are stuck to mesh)on a brick ledge (outdoor kitchen). Thinking it won't be too difficult but want to avoid pitfalls.

At any rate. Wondering how to prepare the surface, which thinset ( I'm planning on using gray so the edges blend better with the mortar that's currently there), and what kind of grout.

Finally, the stone will be natural (not polished) - do I need to seal before I grout? What it the sealant runs down the side of the stone, will it keep the grout from 'sticking'?

Thanks in advance.

The stones won't take a sealer.

Using them out-doors requires a quality thinset mortar. I would use an unmodified thinset but add my own additive. This will make for a better thinset and a more tolerant thinset when it comes to outdoor use and weathering.

Once grouted the grout can then be sealed.
