Fishing for opinions.

Been browsing this forum and the internet on and off for a couple of days now and I'm getting dizzy. Doesn't help that I have the indoor harpie screeching at me every five minutes.
My situation is this. Bathroom, lined with moisture resistant plasterboard, with possibly a 9.5kw over bath electric shower being installed.
Tiles are ceramic, 330 x 250 x 8mm.
Just wondering how you guys would go about completing this project. It's not that long ago, I would have just bought some tubbed adhesive for the whole lot, but I have " the fear " now. I just want the thing done now. Her indoors would have me fixing them with a flour and water mix but that's her way. Don't want to go too over-board but I don't want to be doing it all again in mebbe five years time. Thanks.

I'd be using a powdered adhesive for that size tile.

As above, powdered cement based adhesive. You can get slow setting ones that will sit in the bucket for 4 hours so you can work at your own pace.

[wobblyheed]

Re: powdered adhesives. Any particular one's? There seems to be a lot to choose from even if you're only looking at one manufacturer.

[whitebeam]

A single part flexible adhesive, depending what suppliers are in your area.

[wobblyheed]

CTD, Tile Giant, Topps Tiles (horrendous prices) several independants. Don't mind using the internet to get the right product.
Numpty question. What's a single part flexible adhesive?

[wobblyheed]

Got it. Googled SBF adhesive.

[whitebeam]

It's powdered modified adhesive which has extra grab for the larger tiles, try tile giant..

The adhesive may seem dearer to tubbed stuff but dos'nt get affected with water ingress.

[wobblyheed]

Thanks whitebeam. Would I need to use a primer on the boards first?

[whitebeam]

Only if there is any bare gypsum showing on the boards.

[wobblyheed]

I take it, Mapei Keraflex is the stuff I should be looking at?
No bare gypsum. Joints filled and taped as per manufacturers instructions.

[wobblyheed]

Thanks for the info so far. Off to bed now. As the cyborg duck said, "I'll be quack".

[whitebeam]

Hav,nt used the keraflex, will suit your purpose though..

I would put some primer on the jointing compound.

When you did, did it point you right back at this site?? Think you got it covered but you may want to also think about tanking a power shower area, for paint on kit starting at around £50 it does offer peace of mind. Sorry to throw a spanner in the works

[doug boardley]

I was just gonna mention tanking Rob Wobblyheed, remember to get the adhesive that is closest in colour to your grout to stop it leeching into your grout. ie if you're having a light coloured grout go for a white spf, if your grout is dark go for a grey one.

[wobblyheed]

Ach! Was waiting for someone to mention tanking. It won't be a power shower. Just an electric one. Is tanking really necessary? Does using a tanking kit affect the choice of adhesive?

[jay]

Water proofing a shower area can save a lot of money . It keeps the substrate dry and should if done right stop all leaks in the shower area

as for adh choice depends on what make of tanking . Best to get the adh that will guarantee over the waterproofing you choice

hope this helps

[grumpygrouter]

Mapei P9 will do what you need and it is on a good price at CTD at the moment. Haven't got a Tile Giant near me so can't comment on their prices.
Tanking is advisable as extra insurance against water ingress as plasterboard doesn't like getting wet....even "water resistant" stuff!!

[wobblyheed]

In summary. Fixing of 330 x 250 x 8mm white ceramic tiles to moisture resistant plasterboard.
Tanking kit - Mapei Shower Waterproofing kit.
Tile adhesive - Mapei P9 in white.
Grout - Keracolor FF (?)

Feel free to agree or disagree with any of the above. I opted for mapei purely because I can get the tanking kit for £40.00 at screwfix.

i must be tired i thought it said fishing for onions

[wobblyheed]

Nah, that's the title of me post on the greengrocer's forum.

[wobblyheed]

Well, as no one has disagreed with my summary I'll go ahead and source the stuff. Just like to say thanks to all who responded. I'm sure I'll have some more questions before I get to finish the job. Thanks again.
