Anything other than plasterboard I will prime. When it comes to laying, I'll wipe the wall over with a damp sponge to remove any dust and also the backs of all the tiles. I'll apply dots to a tile in a set formation (not randomly all over the back of the tile) making sure that there is more adhesive on the parts of the tile where I know the wall is out. You can tell whether or not you have enough adhesive on the tile as soon as you place it on the wall. It should take real firm push and a rub (agitates the adhesive) to get the tile flush with the others. If you're not used to tiling this way, of course it's going to take a longer, but for me I do it most of the time so I'd obviously be a lot faster at it. There is no question of the quality of adhesion I get when I tile. Like I've said, the odd occasion I've had to take tiles off, like if one has kicked out or I've forgotten to space it before it sets, it's taken most of the board with it or on solid walls, I've had to smash it then chisel it off with the SDS.
