Good morning everyone... got up early this morning to clean-up the new marble tile counter-top I am currently installing in my kitchen. As I was cleaning the thin-set up I noticed that a few of my spacing's were a bit off. I used 3/16" spacers and I feel like spacers are the biggest rip off. I have done plenty of shower/tub walls, counter-tops & floors with ceramic, porcelain and marble tiles (all on my own properties thankfully) and those stupid little spacers suck! For whatever reason I used them again on one section of the counter-top and will not be using them on any other projects in the future. I installed the remainder of the counter-tops without them and my eyes do a MUCH better job. I'm guessing that since all tiles are not cut exactly the same and that some of these spacers also vary slightly in their creation your just asking for trouble when using them. Anyone ever tried using these stupid little things? If not, don't. Their a waste of money and time.
