slandiHi Bernie, thanks for your feedback. I thought about that as well, which is funny as I had used a notched trowel as is suggested in the mortar instructions. I have done tiling in other parts of the house without issue, I'm figuring that my grout might not have been as good as it could have been. Hopefully I can find the exact same tiles so then as I mentioned in my boo I can undertake removing and then placing the tiles back and regrouting. Thanks again.
topgoldYou've got air pockets that developed when the water in the mix evaporated. I scrape cross-hatching in my mortar mix to minimise settling and evaporation. When I spend the time to do it right.
