Sometimes removing well-stuck tiles can cause damage to the surface they were laid on, eg tiles on a plasterboard wall. Then it probably is a good idea to lay new tiles on top. If and when further tiles are laid, it should be relatively easy to remove layer 2 from the layer 1. But, before laying tiles on tiles take a careful look around to see whether the extra depth will cause problems in any areas. If the existing tiles are smooth, especially if they are shiny, rough them up, eg with a wire brush on an electric drill, to provide a key for the adhesive. If the surface behind the existing tiles is unlikely to suffer damage, it's generally best to remove the old tiles first, it isn't usually hard to prise them up in one piece using a spade chisel and a tap or two from a hammer.

If you want to tile straight on top of the existing tiles then remove all of the grease and dirt with a suitable detergent and score the tiles vertically and horizontally with a tile scriber to facilitate a bond between the existing tiles and the new ones.
There are special adhesives available designed specifically for tiling over tiles, these adhesives can sometimes be used without scoring the existing tiles.
One thing to bear in mind when considering tiling straight over existing tiles is that the new tiles will be at least a tiles thickness proud, this can cause problems when tiling up to edges like door frames.
In the majority of cases it is better to remove the old tiles first, it makes the project more time consuming but the results can be worth the extra effort.

Yes you can, but on a vertical wall you have to be sure the fixings of the first layer are good enough to support the weight of new tiles and that if the walls are plastered, the combined weight won't pull the plaster off the wall!

BETTER TO TAKE OFF THE OLD ONE FIRST, YOU DONT KNOW HOW OLD THE LAST TILE IS AND THE GLUE COULD BE LOSING ITS STRENTH AND THE WEIGHT OF THE NEW TILE CAN MAKE THE OLD TILE FALL OFF AND THEN YOU LOSE BOTH TILES.

no--you will have cracking. i work in a store and sell tile--you need to use durock board. it's a pain to pull up old tile, but it's the only way. you can lay tile on concrete, but make sure it's level.

yes you can, but it's not as satisfying as ripping the old ones off and doing a proper job. When I was at school an old teacher used to rip my work up sometimes, she would always say 'if a jobs worth doing, it's worth doing well' it took me years to figure out what she was on about, now I know, do it right in the beginning, it takes less time in the end and is far more rewarding!!

Yes you can but I believe it is easier to take the old ones off first.
