I would try a consolidator or a densifier.

After this product cures maybe use an silicone dioxide type sealer(liquid glass)

Good Morning Gentlemen,
Looking for recommendations on the very best exterior sealer/impregnator I have two 36" travertine bowls carved from a solid block,that serve a a spillway ,water feature in a  Pool in Florida. It's two years old and was previously "sealed" by pool installer, the stones have etched,inside and effloresced under sealer outside. I certainly know how to address both of these issues,but looking for a sealer that might stand any chance under running chlorinated ,acid treated pool water,as well as brutal florida sun.
Thanks in advance for any ideas
Best Regards
Scott Wilson
