Peel and Stick Pure White 12 in. x 12 in. x 6 mm Glass Mosaic Wall Tile

I think it comes in 12 I believe?

No, this will not stick well to a concrete block.

Thank you for your interest. It depends on how smooth the surface is. We recommand you order a sample, try it and make a decision based on the results. Thanks.

Yes, it can be used on a tub surround. Thanks.

You could probably not put mortar but it looks better if you do. Also if you don't the sticky paper behind the tile will hold any dirt. The tiles are not close set enough to use for a traditional tile with no mortar. It is really easy to grout though. I used premixed grout and it was a breeze. Used it on a vertical and horizontal surface. Really liked the peel and stick tiles. Will use the again.

Yes, I didn't use a wet saw--just a utility knife to cut around outlets. If you want to hang picture frames, I recommend command strips. It's not worth drilling through the glass to hang small items on.

Thank you for your interest in Instant Mosaic. The tiles are safe to be installed around a fire place ; the tiles can resist heat up to 170 degrees Fahrenheit. Thanks again EKB Innovations.

Dear Valued Home Depot Customer, We reached out to MFG for more information and below is their response. " You can use either white ceramic trim or metal trim to finish the backsplash. Thanks "
