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

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!

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!!!

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 .

If they did they would all be out of business...

Im not some random username on the net, i and id say thousands of others will stand by by saying 25kg will hold up for decades on skimmed plasterboard walls.
I would tile, as would thousands of others and stand by the customer and telk them it would be fine .
And Just because 5 or 6 random names tells someone not to do it on the net does not mean they ate right .
Do a test, prime a bit, wack a tile on it, leave a few weeks and see how hard it is to get off ?
Now get back on them roads with your 30mph sign and high viz on you dwebe

"Always remember insurance never payout if the day you submit claim on has a y in it" ." If they did they would all be out of business..." Sorry Nic all they'd do is stick our premiums up & blames it on some obscure world phenomenon that happen or about to happen

No problem. I think you made the right choice. Good luck with sourcing the Tiles

I am sure there are loads of people who would do it and you are probably right, it more than likely wouldnt go anywhere, I guess as someone who isnt in the trade as such it makes it a bit daunting when doing something like this and there is a risk of it failing in a few months/years...

I also agree fully that there is a LOT of scare mongering online from people who "Know Best" as they have read a text book or are up to date with Regs, but have probably never laid a tile/brick. In my books, experience is far more valuable than information gained from a book...

Ive got the wife breaking my chops to get it done, in fairness, she has been waiting about 8 months, so i think a few more weeks may end up with me in the kennel, or in the incomplete ensuite!

In your opinion, you'd go for it, even though its around the 25Kg mark?

Any thoughts on the Ultra adhesive i'm looking at using?

Thanks for the honest response as well, much appreciated

Not a problem nic, you need to do what you want , its your house not mine and you’re the customer
As for ultra ive no idea,neverused it, but if its a s1 its fine for walls.
Edit, its a s2, no problem on walls

Had the bathroom suite 18 months before I did ours & when I did get round to doing it didn't like it, going to do it again later this year

I read this years ago, this happened local to me and a reason everything I do, I do to the book.

I’m not saying the same will happen with tiles falling off a wall but if it did at least I would know I did everything correctly and couldn’t be at blame.

Sad, unfortunately there's no control over these people somebody pointed out on another chat that you can buy a trowel & a bucket of adhesive and start up a business & carry on in the trowel trades eg tiling , plastering because these people think along the lines of how hard can it be to put one tile on top of another. The average Joe's out there can't do that if they had to do gas or electric because of the lives they could put at risk so there is were the problem lays

Funny thing is the person who said that isn't a tiler so is doing exactly what he is being critical about .
