The flooring is Arto tile, it is cement tile- about $9/sqft. Expensive but beautiful! We are about to do it in our kitchen!

Do you know what sealer was used for the tile?

I am not sure what the sealer was because I spoke to a friend who had recently installed Arto tile in her entry way. She had it 3 months and it was already all scratched up, so way to repair it. So we did not do this, used porcelain wood plank tile instead and it looks amazing! Get tons of compliments on it all the time!

If some one installed Arto and it's all ready scratched up in 3 months it's probably because a topical sealer was not used. If you have a stained Arto product, I strongly recommend a topical sealer to protected.
