is C2TE tile adhesive ok for bathroom?

[Laubi]

hi all,

bought this as it was the only standard set adhesive in the shop at the time. Only just realising this is not an S1/S2.

Is this ok to use for bathroom wall/floor? be using porcelain tiles on hardiebacker boards

Have you read the data sheet? That's what I'd do.
Look it up online

Yes I have but I have no idea what to look out for here.

That's the safety data sheet. Called coshh. That's not the data sheet.

COSHH stands for the Control of Substances Hazardous to Health regulations,

You want the data sheet. That's is instructions. Where to use. How to use. How to mix ect

 

[Joe Fixit]

It's the only datasheet on the site. And I can't seem to find anything on this product on Google!

I guess for bathroom floor/wall tiles, it has to be flex(S1/S2)?

Thanks, thats really useful. But problem is that the one I got doesn't have any of those brand/model names.

It does say on the packet it's suitable for showers and use even in underwater. But I just didn't know if I really need to get one where it's certified S1/S2 as I see people say best to use flex adhesive

Also this information

Hopefully it will help you. There are other downloads.

They also should have a technical helpline.


I think you should use flexible not standard.
Standard is for solid floors

You definitely need to use a Flexible on the floors. As there’s no ‘flex’ in the products name, I would err on the side of caution and presume it isn’t.
( and I take it you’ve noticed it’s Grey ? )

Why don't you just ring up Mapei, all these kinds of manufacturers have technical departments and get these kinds of queries every day, they'll tell you the best one to use rather than you second guessing 0121 5086970. Weirdly I can't see that exact product on their website, which is where you would find the data sheet.

 

[Joe Fixit]

Thanks all. Will give them a try but suspect it's not flex.

Do wall tiles need flex? Just wondering if the bag Ive got isn't flex, whether I can still make use of it

 

[Laubi]

I rang technical support and they say that this does not have the S1 flex certificate.

But he also advises that I do not need flex on a bathroom floor if laying it onto hardiebacker.

Any opinions on this please?

For the sake of an extra fiver a bag, are you going to risk not using flex on the floor ? I've tiled loads of floors over the years, and never used anything but flex - even if it doesn't need it.
But you deffo don't need flex for the walls, in fact the extended time this bag claims actually makes it ideal for a diy wall tile adhesive.
( as long as your grouting with grey )

Thanks. That's good then. I can use it for the walls and get a new bag for the floor. Thanks!!
