My brother and I installed 20X20 porcelain tile in my mother's basement. We tiled over the cement basement floor and now have to put in the grout and seal the grout. I liked the large tile size but getting adjacent tiles lying flat was a struggle.
My mother's home is in central Minnesota near one of our 10,000 lakes and the basement gets humid in the summer. We have a dehumidifier running to help remove the humidity. We need a grout that can handle this situation.
I have read a few posts recommending epoxy grouts. Would they be a good choice for our situation? Which grouts have a good reputation and do I need to go to a floor supplier to acquire a better product?
I am also looking for a grout sealer that would be best for the conditions I have stated above.
Your opinions and recommendations are welcome.
TIA, Terry
