Home buyers still appreciate travertine. It’s elegant and has a crisp, clean look. Travertine can be a challenge to keep clean however because it is porous. It’s important to seal the travertine – a couple of coats – to make it easier to clean. Otherwise, polishing powders, and such, can accumulate in the holes. Travertine is great for floors, but not as good an idea for highly used countertops.
