Advice on Re-tiling New Build Walls

[chrisab]

True true Ali - If I need to get all the existing adhesive off it might be easier to re-board! I presume though as long as you get the worst raised bits off that should be OK. Cheers

To be honest fella weighing up the options the only deciding matter is cost.

It will take time to remove the tiles, scrap the walls and prep for fixing your new tiles. Where as if you can afford to re-board then pull the lot down, boards and tiles together. Baton and insulate the cavity (if need be) and install some tile backer rather than plasterboard. Get a tanking kit for the wet areas and away you go. You'll get a good surface to tile on and therefore a better finish and the jobs done right.

But i'd say time to do either option is about the same. So for a few sheets of your hard earned you'll put a longer life expectancy on your bathroom, and a better final finish.

Hi,

Right i think I will take your advice and re-board the main wall as i will need to put some pipes in for the new shower anyway.

So I was thinking water resistant plasterboard everywhere and tanking around the shower area. (or is there a real advantage to using hardiebacker around the shower - or everywhere for that matter, obviously it will cost more).

I will also need to replace the enclosure/shelf above the bath as its rotten and mouldy (it's like a double shelf into the window). Should I replace this with plywood and the hardieback over that or will i get away with using 12.5mm hardieback as the shelf itself and tiling directly to that?

Thanks!

personally chris,if you are tanking it,plasterboard will be fine,and cheaper,if you want to go to the expense of hardibacker,which will not break down like plasterboard if constantly wet,get hardibacker,its great stuff,but twice the price if not more

and use a good adhesive,not tubbed its rubbish, mapei proflex is a good un,and you can use on porca or ceramics

[chrisab]

thanks widler, do you think plasterboard to make the shelf as well?

[widler]

Should be fine with plasterboard.
Make you sure trowel the addy on the wall as well, don't dot and dab the back of the tile, and spread a thin lair on the back of the tile with the flat edge of the trowel

Shelves and sills imo should be hardibacker. On a shelf there's a chance of water pooling as it can't run down the wall. Seal the grout and use the hardi to be absolutely certain your pantene has somewhere water tight and strong to sit. If any water gets through the tiles and grout on your shelf the plasterbaord is ruined.

if its that bad for plasterboard to get ruined,you would have to re do the job anyhow,and if the jobs done right,it should'nt fail

the only time i have seen plasterboard get that bad is through pipe leaks,roof leaks and bad tiling,where water has been penetrating plasterboard for months.
if the jobs done right,you should have no problems with water ingress

Each to there own. I just see it for an extra £6 i get piece of mind my work will stand the test of time. When you see the state of some of the bathrooms i rip out. Just my preference.

[widler]

yup,they are a right mess,ripped many out myself,including one at my house,totally agree mate,and most of on have not been tanked and been tiled in tubbed addy

[chrisab]

thanks for the replies, much appreciated. I was going to tank all the shelf etc. as well. I've started ripping it apart and there's a metal strip on the edge of the step - i presume that is just to get a straight edge on the tiles?

Is there a cheap place on the interent to get tanking kits etc. from? I think there is a topps tiles, b&q, wickes around us buts thats about it.
