New tiles on top of old tiles is OK. It is a very common practise, almost
obligatory in fact when you consider the alternative. No need to replace the
old broken tiles, just fill up the holes with plaster.
There may be a different adhesive but I have never seen one.
All kinds of edging strips can be found in most DIY sheds.
| I'm pretty new to DIY and am having an new bathroom suite installed and
| would like new tiles around the bath, I can't afford to pay someone to do
| it so I want to have a go myself.
| There are old tiles around the bath, and I have tried taking them off but
| they seem to take most of the plaster from the wall of as well, revealing
| wooden strips. The old tiles seem really firmly attached, would it be OK
| just to tile over the old ones? as I don't think I could re plaster the
| wall and would rather not have the expense.
| If I can do I need any special tiling adhesives or would regular ones do?,
| also what would I do about the sides of the tiles to finish them off as
| would be able to see that the two tiles were there and it would be extra
| thick, can you get some sort of trims?.
| Also, I've already removed about 4 tiles and have a hole where they were,
| what should I fill it up with to level it up to the tiles I have taken
| should I replace the tiles that I have taken off ( I don't have the
| originals as they are in bits but I could get a few cheap ones) or can I
| just use filler or plaster to make the level up?
| Sorry for the length of this post and thanks for reading it, any
| suggestions appreciated,
