Can kitchen counter tile be installed with really tight seams, perhaps using a resin instead of grout?
YOu really shouldn’t go smaller than 1/16th of an inch. You need to get grout in there to make the tiles secure. It isn’t in there just to fill up a gap. It is part of the bonding and attachment process. I know that people who use granite tiles want them to look seamless but it isn’t a good idea. If you have questions as to how to best put them on your counter you should visit the John Bridge Forum. It is the BEST DIY place on the internet. It’s all about tile but they are very friendly and can give you loads of answers. They are the best out there for tile and concrete questions.
