We had never done any tile work ourselves so I personally was a little nervous but I will say it was pretty simple for us layman's to do this in one weekend. We spent apprx. $200.00 on everything.
First we removed the old Fake Tin Back Splash.......
We pre-cut the tiles that needed trimming around the electrical sockets and garage disposal switch. We did not rent a wet tile saw. We used Tile Snips that we bought at Home Depot. They worked perfectly.
Then we spread out the Thin-Set Mortar with a trowel. We used a Pre-mix kind. We worked a square at a time. (Since we pre-trimmed our tile it made this process very simple. Once we had it all up, we let it set-up over night.
The next day was grout time! Again, we used a premixed grout. We used "Natural Grey" color. We taped up our countertops and cabinets and covered the countertop in plastic for protection.
We used a rubber like thingie to push the grout into the spaces. (I have no idea what this tool is really called! It came in a Back Splash kit purchased from Home Depot.) You do this a 45 degree angle so you don't pull the grout back out.
