You can cover ceramic tile with almost any flooring after proper preparation to smooth the surface and achieve an installable substrate for the new flooring.

If the "paint store guy" could not give you the name of his product which he knows for a fact has been done successfully many times, how are we supposed to know? There are epoxy garage floor paints. they look like painted garage floors at best. You sprinkle the little colored chips on while it's tacky. Otherwise it has one flat unbroken color. There are kits sold for simulating granite, etc, but they are not suitable for floors. The Sherwin-Williams article in the link below specifically discourages the idea of painting tile in high-traffic areas.

I would for the dam use the floor tile for sure. It looks really good and help keeps the floor from getting too busy. We did a shower build last year with the wood tile and changed a small neo angle shower into a large walk in shower with low curb. We used the wood tile for the shower floor, bathroom floor, shower curb and walls.

After thoroughly cleaning the floor, I used a bonding primer by Valspar as my first coating. You can use 2 coats, but I only used one coat. A bonding primer prepares the surface to accept the paint and grips it. Then I used Behr"s porch and patio floor paint. It's a great outdoor water based enamel low sheen paint. I used 2 coats as I was covering dark brown tiles and dark gray grout. I let that cure for a week. My next step was to use the blue left over paint from the walls, Sherwin Williams eggshell Ocean Breeze to stencil. I picked a stencil that would be easy to use for a first time stenciller. I used a firm foam roller. It was so fast and easy to do until I got to the tiles that were partial. My tiles were laid diagonally, so there are so many cuts, but I do one tile and then wipe the stencil and let it dry before going to another tile. I've got a lot of time, so there's no rush. the reason I do this is because sometimes you have to bend the tile around the toilet base or just a small piece of the tile is cut off. Now I'll cut the stencil to finish the triangle tiles that are left. That is the tedious part. I'll let that cure for another week and then apply the protective urethane. I'll use 2 coats. This is a guest on suite bathroom and I think that should be sufficient. I'll let that cure for a month to be safe. I won't have guests until Thanksgiving, so it will be perfect timing. Thank you all for your help and comments. My next bathroom floor will have a different stencil. I have 4 bathrooms and a laundry room floor to do. The laundry room is a concern. I'm worried about moving the washer and dryer across the floor and damaging the painted tiles. I can't lift them.
