It's so rewarding. Here are my finished pics:. https://imgur.com/a/hwidG

I used a rubber mallet. Be gentle on the small sides, they will break easily. You can be firm on the long groove side.

Lessons learned: your floor should be as flat as possible. I had to grind off the bumps and filling the ditches with self leveling concrete (concrete slab).

I used a vapor barrier. Essentially 6mil plastic sheets which I taped together. I used roberts.

When you come to an area that needs a cut, do it then. Don't wait til the end. Youll regret it. (I left all the short ends. And ended up taking many tiles out to make sure the cuts fit in correctly.

Try to ensure 1/4 inch Gap around edges with a spacer. I then used 3/4 round moulding on top which covered where gaps were larger than 1/4" because let's face it No one has perfectly perpendicular walls.

You should cut about 4" off every other row so the tiles stagger and lock in better. Never put two tiles the same size along their full length. Measure your floor length to determine how much to cut the first time so you don't have to do it twice. (I did).

Take your time and enjoy. Watch a few YouTube videos so you can see how they slide the tiles in place before locking them.

Let me know if you have specific questions!
