We recently had our travertine floors refinished and they look great.
One thing we notice in the last couple of weeks that we have stains...non acidic from water, etc. in bath and kitchen. is this normal?
I am wondering if the sealer was applied because the refinishing was done this summer when we were not here.
Is there a way to tell if sealer has been applied?
I don' think you are seeing stains in you travertine. They are most likely etch marks.
A sealer will not protect from etch marks and so any liquid or food slightly acidic will etch the travertine.
I see these etch marks all the time and most people think they are stains.
Even though travertine has many holes, it actually is very dense and doesn't stain that often.
The way you can test to see if you travertine was sealed is put some water on it for a few minutes and then wipe up the area.
If you see the area you wet become darker, the stone absorbed into the stone. You can do the grout too, as the grout is much more porous.
When they refinished your travertine, they most likely sealed it, but like I said, you most likely have etch marks.
A stain will most likely be the color of the staining agent, and etch mark will just be a mark on the stone, that won't clean up.
Also, if the etch mark is deep enough, it will begin to attract dirt and become dirty looking.
I don't see many stains in travertine, but I see etch marks on probably 95% of travertine floors we work on.
I hope this information helps.
