Look who's got to tile a bathroom soon

[Dan]

Got a bit of tiling to do myself soon.

I won't be back buttering anything.

Porcelain 350x350 on floors and walls and some boxing in and maybe a removable bath panel and some shelving hole things.

Got aquapanel for the floors and shower.

Don’t forget Aquapanel is not waterproof, it has to be tanked according to new BS5385 regs.

Good luck 🙂

 

[Dan]

On it matey. 🙂

Just out of curiosity, why wouldn't you back butter the tiles?

 

[Dan]

Because on the floor I'll get full coverage without needing to, and I'll check periodically (and it's only about 2.5sqm). And the walls I'll prep. I'm lowering the ceiling and plasterboarding that. Building my boxing with aquapanel. Already fitted a new suite and put ball valves on everything so it can come out or at least be moved to tile behind.

And the tiles are fully vitrified porcelain in dark colours.

And I don't want to use more adhesive than I need to. It's an S2 and I don't want shrinkage. Everything will be fresh and flat.

Why would I need to?

 

[WetSaw]

A skim isn't enough adhesive to worry about thickness or weight but will fill any indentations in the back of the tile and, more importantly for me, will remove any dust and improve adhesion. For the couple of seconds it takes I really don't see a reason not to.

 

[Dan]

No need make a slurry or anything IMO.

I must have missed the memo on this skimming the tile lark because it wasn't part of the NVQ.

Because of its low absorption rate and that it needs to be burned in to the pores of the porcelain, like I mentioned in my first response in the previous thread.

Alright then that's that done eh. 🙂

Certainly not digging you mate, honest, but you asked the question, that’s all Dan.
There’s been massive changes within the industry of recent years with more to come, especially centred around ex large thin porcelain.

You can see it all too plainly on some of the failures we see on here on a weekly basis, you’ll see the indentation of where the tile was just sat on the adhesive, plainly leaving visible print of the back of the tile in the adhesive. It’s not solely the reason obviously, but it goes some way to explain why a floor or wall may of failed.
It’s actually unusual for a failure be accredited to one problem, most failures are an accumulation of several small mistakes.

@Dan
do You understand now?
or not?
otherwise I will also explain the UNI standards

 

[Dan]

I understand mate.

I wont be skimming them though. I'll make sure I check coverage as I've always done. But it's an S2 so it's going to cling to them well I think.

I thank you all for your advice though. As always. 🙂

I'll post some pics up ASAP. Not sure if I'll get round to it before my hols towards the end of the month but I'll see what spare time I have.

with a 35x35 the buttering is not mandatory,
over 60cm on the side yes.
except that once I started making the butter,
you do it automatically with all tile sizes,
because you realize that it is better to do it.
