Bathroom Prep Help - Skimmed Walls

[Nic B]

Hi All,

I have spent all day reading the forum but thought it best to ask the question direct for some feedback.

We have an ensuite in our new extension which we are tiling, however, the builder has skimmed the entire room and did so before I knew the weight limits on skimmed walls etc. Needless to say I am in a catch 22 at the moment and need some advice really.

2 of the 4 walls are stud walls, one is dot and dab plasterboard onto the original house wall and the 4th wall is insulated plasterboard, so a real mix!

I wanted to get peoples thoughts on the best solution as I have already bought porcelain tiles, which I know are over the 20Kg/m2 limit, but would it be cheaper to

A - Just buy new tiles that fall within the weight limit
B - Rip out the plasterboard and reboard (Hard to do with the insulated plasterboard wall and has to be insulated for building regs)
C - reboard with new plasterboard over the 3 walls using mechanical fixings (Which doesnt solve the problem with the insulated plasterboard??!)

Any thoughts appreciated.

Thanks,

Nic

Change for a lighter weight tile you said you can sell on the porcelain ones on ? then it problem solved and alot less work . Kop

Hi, have you weighed the tiles ?
I bet you are not far off withthe weights, unless they are 20mm thick ?
The limits are a guideline , and ive searched the net and I cannot find anywhere in the known world a cat being killed by a tile falling off a newly skimmed plasterboard wall never mind a human .
Im more or less 100% sure every tiler has exceeded the limit at some point j, i have many a time 😉
Waligi probably hasn’t though, i bet he is one of those blokes who stands at the side of the road waving his hands and pointing angrily when you are driving 32 in a 30 zone 🙂 🙂

Thats what I am starting to think, everything is pretty much ready for tiling, so not sure its worth ripping out again and starting fresh for the sake of a few quid on new tiles! Cheers

Hi Mate,

Thanks for the reply. Yes I have weighed the tiles, just over 21kg/m2 for the tiles alone, chuck some addy and grout in and we at around 24 -25, which is why I am concerned.

I would agree that most tilers have gone over at some point ans that BS are probably way over cautious, much like most H&S rules! I we were at 21 including the addy and grout i'd have probably gone for it to be fair, but we have already spent double the original budget so if anything goes **** up in 6 months time i certainly wont have the money to sort it out and start again!!!

"ointing angrily when you are driving 32 in a 30 zone" - There's always one 😀

Forgot to ask - in terms of prep, walls are obviously skimmed and need to be primed, no problem there, do I need to key the plaster for a better bond or is priming sufficient??

Any thoughts on the Ultra Pro Flex S2 Ahesive? I used it for the underfloor heating and have a couple of bags left over, the way I look at it is if its good enough for a swimming pool then it must be good enough for a shower?!?!? Also still have some of the Ultra grout left, also used in swimming pools! 🙂

Absolutely!

If you did exceed the weight limits and it failed then it would be irrelevant that a random username on the internet said it would be fine.

Yip, dont see the insurance or trading standards being too interested when I say someone on a forum said it was ok so it must be true!! 😀

Been having a look at options on tiles and new tiles is going to be around 300 quid, so I think it outweighs the labour and materials to start again!

Thanks again for the replies

Me too. For years I've wondered why we don't have more inspection and sign-off before completing work ready for the next trade.
I've decided that the reason is that it would begin to eliminate the stupids and the world is run by stupids so that would never do!

I didn't know wether to reply like ,funy or agree

Always remember insurance never payout if the day you submit claim on has a y in it .
