Hello
All screeds for wet room are done ,the plasterer has asked me what do i want on the walls in the bathrooms of the new build ,
options are
1 Leave blockwork as it is and tile straight on
2 scratch coat and tile on
3 scratch and skim with key then tile
Which would be better for the tiler at the later stage
Help appreciated

the best substrate to tile onto it is scatch and skim,the down side is the weight issue,if this is going to be a problem i would go straight onto the blockwork

hi if bricks are plum and flat thats best option
if not render then tile

or a flat sand/cement rendered wall

I agree with Jay, brickwork if fine to tile straight onto, the problem with it is that it is rarely flat enough to tile without covering it first.

What tiles do you intend to use..? this will help decide what to finish the wall with..

Hi all and thanks for your help , these walls will be tanked as it is a wet room ,so would i be better putting a skim coat and then tanking and then the tiles which i think at this a large format on the walls ,
Thinking about it it would be difficult to tank rough blockwork
Ta

13mm single render coat would be the best option

If time permits render takes some beating imo, then tank

If they are large format i would avoid the skim as you could be over the safe weight limits.

Just wanted to say thanks for your help -render it is
Regards
