Travertine over slab
Hey Hardwood, "overkill if he seals the concrete?", the man wants to install travertine tile, you don't seal the substrate when installing ceramic or stone tiles....ever.
What specific brand and type of thinset were you going to use?
BTW, everyone should give their name in the post.
