Good evening all. This is my first post. Please excuse me if this question has already been asked and answered.
I did perform a search of the forum but didn't find the answer.
I have a newer or newly remodeled bathroom in the lower level of the house that we just purchased a few months back. I say newer because it appears that way compared to the rest of the house.
My question has to do with the tile floor and the shower stall tiles. How do I know if grout sealer has already been applied? Do I not be concerned as to when or if it was and just do it again?
Thanks in advance!
