Tiling Onto Carlite Bonding !

[Monkey Wrench]

Can you tile directly onto Carlite Bonding ?

The plasterer (who bonded the walls) advised to Unibond (PVA) prior to tiling but, as far as I'm aware, that's a definite no.

I want to get on with the job but I'm reluctant to tile directly onto the bonding as I'm sure it will just suck all the moisture out of the adhesive leaving a pile of tiles on the floor (and not on the wall where they should be).

I've read so many conflicting opinions on this matter and still do not know one way or the other.

Any advice would be much appreciated.

Thank you

Its not the done thing but if you have to, prime the walls with sbr.

Thanks for the post afright.

What would you do, if you were in my position ?

no you cant tile onto bonding, and do not use pva, and i wish some plasterers would stop advicing this.........its wrong, wrong, wrong....

Thanks for the post. What would you recommend I do then ?

As Andy say's, its a big NO NO.

Get it skimmed.Also bonding is not suitable in wet area's

get it skimmed , or remove bonding and board with new plaster boards , what size tiles do u intend using

 

[Dougs Third Go]

we could really do with knowing what type of tiles you plan on using, specifically the weight per m2 of them. But certainly no tiles should be fixed directly onto bonding coat.

Thanks for the posts.

I'll get the walls skimmed prior to tiling. I'm not sure of the size and weight per m2 but will find out and post details.

Out of interest, is there another material the plasterer should have used (instead of Carlite Bonding) that would have made it uneccesary to skim the walls for tiling ?

Thanks again.

Thistle dri-coat base cement coat could have been used to tile on.....If the bonding has dried out and the need to apply a finish is required a coat of pva to cut the suction down for a slow setting finish would be required but that will only take 20kg m2.

Thanks for the post whitebeam.

I take it that by "slow setting finish" you mean the drying time of the finish coat ! If so, how long after the finish coat had been applied would I be able to start tiling ?

I'll check the m2 weight of the tiles to make sure its within the 20kg.

Yes mate, all finishes need a low suction background and thats the reason to use pva.....

I spoke to the plasterer this afternoon and he has told me that carlite bonding is perfectly ok to tile on providing the suction has been neutralised by applying something like Bal Bond SBR prior to tiling. He says that he's quite happy to skim the bonding but thinks that it will be a waste of my money as all I'd be doing is paying for an additional finish to tile (glue) onto when the bonding is a perfectly good tiling surface one primed with SBR !

I'm certainly not doubting any of the excellent advice I've received on this forum but just confused by the conflicting opinions !

on tghe other thread it was pointed out that even britsih gypsum say it is not suitable to tile to, so you'll see your plasterer is wrong and maybe if you showed him the data sheets for bonding then he won't mis-inform people in the future
