moisture resistant platserboard

[negsy26]

hi guys, tiling a bathroom soon in a 1st floor flat, the bathroom has no window and it has moisture resistant plasterboard all round.its not got a bath but will have a shower. customer syas he doesnt want to pay out the massive expense ( about £50!! ) for a tanking system in shower area when he says that his plasterboard is moisture resistant and will be good enough. im not sure about this at all but really dont want to loose the job as he could be quite a good contact, i think he really needs the tanking system but what do you guys think? and also do you prime moisture resistant plasterboard?

Its what it says, its resistant, its certainly not waterproof.

If you want it waterproof, it'll need tp be tanked.\

And i think it only needs primed of youre using a cement based addy.

Tank it, or dont do it. First floor flat, imagine the mess on the ground floor if there is a leak, or the state of the plasterboard over time.
You could just price it in and dont tell them your tanking it and do it anyway.
Iye prime the plasterboard.

Also explain that not wanting to pay for something just because you dont see it or immediately see the benefit of it is very shortsighted. Why bother doing a bathroom up at all then?

Also your reputation is on the line here, your the tiler, do it under your terms or not at all.

Good luck

yeah thats sound advice i dont really know what the guys thinking is! its gonna be tanking in the shower area or he can get someone else to do that bit !! so a standard acryllic primer is cool for moisture resist p-board then?

I wouldn't force the issue, it's his decision. I'd xplain the benefits of tanking, and that moisture resistant plaster board isn't meant for showers, but i wouldn't throw a job away over it!?!

no you don't need to prime it if you are using -based on the cement green one but you will be best to use spf as the moisture resistant surface wont adhere as well as the ordinary plaster board I always advise my customers not to use it ete

have you not got a bit of tanking left from an old job? get two bits of the same board, coat one piece up, then dunk both bits in some water and give them to him. As mentioned before don't push him but explain at the cost it's a no brainer

i would also suggest an expelair,a bathroom with no ventilation and no tanking isn't the greatest scenario,personally i would explain to the customer therte would be no comebacks if dampness progressed through to the plasterboard as the moisture will sit on the tiles and grout and over time eventually penetrate through,but then you wouldn't have a leg to stand on if he took you to court as you know better and have carried on with a job that does't meet satisfactory requirements!
leave it well alone!!!!!!!!!!!

i like the idea of getting a bit of the board and dunking it in water !! im gonna give that a go. and after all the advice on here im leaving well alone if he still insists.

You can only advise what you think is needed...don't loose the job over it....depending on how often the shower is used , as to how much ingression will happen..at present it isn't uk law to tank..it is a worthy thing IMO but don't throw a job for a customer not wanting it done.

valid point dave, i checked out the link whitebeam posted, it says it can be used as a base for tiling in wet areas !! now ive got a bloody headache !!

When it says "wet use area" it basically means a bathroom. It doesn't actually mean a wet area, such as a shower/wet room. As Dave says, tanking isn't part of British Standards as yet, so you shouldn't have any problems in court. You could always state on your invoice that tanking was declined by the customer, as a bit of extra back-up should the need arise.

all sorted, the fella's gonna pay cash so no invoice for him !!
