Hello, My name is george, I am trying to create a mosaic design over a painted concrete path, for my granddaughter. Question 1. will I need to do anything to the ensure that the 'bedding mixture' sticks to the painted concrete. Question 2. What do I use to 'bed' the mosaic tiles (ordinary floor and wall tiles cut down to usable size approx 1") onto the painted concrete. Question 3. Does the mix have to be a certain thickness, I will be making stepping stones, so the mosaic will not be walked on. I will be using 1" high battening, is that thick enough. Question 4. I intend to use 2" x 1" battening to contain each mosaic design, about 3' square, the path is 6' wide, what do you suggest to fill the gaps where the battening will have left, when I remove the battening. Question 5. what type of grout do I use, to finish the mosaic, and do I need to seal everything when I have finished. I would appreciate any feedback, no matter have trivial, I am a complete novice at this type of enterprise, But a promise is a promise, and I would love to be able to see the 'smilie face' on my granddaughter, if I could achieve her suggestion. Thank you so much for any help you may be able to give. George.

I have 13x13 tiles going down. I just started laying down 1/4 hardibacker over a 2" subfloor. When I lay these tiles can I just back butter the tiles without having to put thinset on the floor, I heard this is a good way for beginners to set tiles without such a mess. 2: My floor is level but as you run a 4ft level over the floor to see if there are any pockets I have a couple of places that you can just see under the level 1/16" if that, is this going to be a problem or will the thinset fill these small pockets when laying the tiles. thank you Ken
