problem

[fergie]

i have just finished a bathroom with 60 by 30 tiles but had trouble getting them perfectly flat walls had been plastered is this due to lack of adhesive can any body help for future jobs

you need to give a bit more detail , it could be a number of things ,plastered walls arent normally that straight most plasterers just skim over the bumps so they are still there when they have finished you need to do good preparation before you start chop out any bumps,prime the walls and skim out any hollows with cement based tile adhesive and a straight edge ,next is to make sure your tiles are not bowed if you are doing brick bond with bowed tiles you will get lips no matter how straight your walls are

It all depends on how flat the wall are after being plastered to start with, and what sized notched trowel did you use and how thick were the tiles ?

and having just started you have gone in at the deep end,especially if they were brickbond and even worse brickbond B+Q.
check your walls first for flatness forget level it means nothing,flat is what is important,you only need to worry about level on the external cornered walls.
many bathrooms wont have a external cornered wall apart from the soil stack and the window.
10mm trowel will be needed but as stated before check for bowed tiles,a way to make sure a 1mm bowed tile is stuck is to back butter length ways making sure your trowel over laps the 2 edges of the tile personally i do this anyway with anything over 300x300,pull off a tile after you put it up and it may need a bit extra across the middle,but using a 10mm trowel and back butter you should hit the adhesive fine.
if the walls are not flat you have no chance with brickbond you will always get lipping,so its a case of do i do the job or not.
soppy bloody plasterers will always tell the punter the tiler will get over that.
always remember its his job to make the walls flat not yours if you go over 12mm of addy even with many SPF you are on dodgy ground,the first tile needs 2mm more the next tile needs 4mm more and so on just to keep the wall flat.
so always check for flatness and know the tile size when quoting.

I'm with you man plasterers I'v s**t em

[fergie]

yes they were b&q tiles and every pack were different in size as well i did use a10mm trowel is it best to check flat walls with a feather edge the job was for a mate he had already purchased the tiles but i needed the experience thanks for the replys

I Tiled a batroom on Monday which had been plasterboarded and taped and jointed, when i came to tile over the joint the tiles did not sit flush lipped because the bloody tape and jointer just slaped it on the wall looked a right mess.
