Advice on Re-tiling New Build Walls

[chrisab]

Thanks for you the help, much appreciated, I'm sure I'll be back with some more questions soon, first though more research needed. Thanks

Your internal walls are all likely to be timber frame and plasterboard. If it's the original tiles on the wall have a go at knocking them off. Someone above mentioned tubbed adhesive thats true and it's usually used direct onto the plasterbaord/skim in a property of your age. You might knock the tiles off easy and find all the adhesive is sill on the wall.

Hi,
Right I've finally got around to stripping some of the tiles. Them seem to be coming off ok, taking some adhesive with them and leaving some on (not exbosing any plaster though - just brown covering). I've noticed the boards have come loose where they are secured to the stud wall. Can I just screw the platerboard back onto the stud wall and plaster over it. Does all the existing grout need to come off or can i just tile over it?

Thanks

Get yourself a blade scraper and try and get it all off. More you get off (and keep the board intact) the flatter and easier you'll find tiling it.

It's really hard to say for sure what will happen when you start, every job is different.

I'd price up for having to replace the plasterboard walls, as these will more than likely drop to pieces once you start.

Ripping tiles off is a horrible job, damages the boards and could cut you to shreds (very sharp tile shards).

I reckon there is 0% chance of it being tanked, (virtually no-one did then),so if you are worried about moisture after you tile then you may as well rip the boards off and replace with Marmox boarding (at least 12.5mm).

Tiling 20 years was not as advanced as now, it would have been plaster board, maybe skimmed, a big gap over the bath, original Bal Grip adhesive (at best) and fairly duff adhesive. Its done 20 years, redo it again and make yourself proud by having a nice up to date shower that will be infinitely easier to tile than a rehashed one.
Everyone here will advise you well, it's nice here!!!

Completely agree with you bugs. Myself and a few others advised replacing the boards but i think he's content with just taking the tiles off and going over the old board.

Cheers Al, it sounds like the boards are coming off cleanish in this instance, it does sound like Chris wants to do a good job, especially with maybe getting it tanked, but as we all know if it looks like Rocky has been using it for punching practice then its back to the drawing board!!

Re-boarding is a relatively inexpensive job, and simple enough when it's going on studwork. You'll appreiciate the flat sureface when it comes to fixing.

Thanks for the replies guys. When i sadi "can I just screw the platerboard back onto the stud wall and plaster over it." i meant ...and tile over it.

I'm happy to put new boards up if necessary but if not then obviously if it saves me time and money by not doing it then great! If i keep the existing boards I'll tank the shower before tiling, if i re-board I'll use the board you have described.
The existing boards look ok but have popped away from the stud wall in places so might need to be screwed back down. Here's some photos of what I've done so far - please let me know if you think I need to re-board. Thanks

You're only as good as what you're going onto! And sheets of plasterboard are only about a fiver each anyway, if I can't clean it off to a decent standard in under ten minutes then it's cost effective to just replace them

 

[AliGage]

Agreed

 

[chrisab]

I has posted a message with pictures but it hasn't shown up...I'll try again

[AliGage]

They don't seem to be coming off too badly. I wouldn't get too excited until you've detiled the whole room though

 

[chrisab]

Hopefully the photos give some detail. Do you think it is better to replace them or just tile over (I have no problem re-boarding except it will take time).
