Tiling Onto Carlite Bonding !

[Stuart Williams]

Don't understand the sand/cement bit, pva and a multi finish should suffice...there has been talk recently that no pva should be used in any moisture areas involved with gypsum plaster.

Thanks. I was wondering if a sand and cement mix would be an option for a finish, but it seems as though a one coat or similar plaster finish should do the job and ensure I have a good surface to tile on once it's had time to dry. May be worth looking into SBR over PVA then, this tiling was supposed to be a simple job but seems to be quite technical

Sand/cement on top of a bonding coat is a big no no, the reason a pva is used is that it needs to tacky whereas sbr doesn't really give you that option.

A thinned coat coat of pva, leave to soak in then a thicker pva wait for it to go tacky then apply the multi finish.

The bit about no pva in bathrooms etc, been doing it for donkey years so shouldn't sweat on it.

• Tiles up to 20kg/m2
can be applied directly to Thistle finish
coats. If a bonding agent is used the limit is reduced to
12kg/m.

Thats something I never knew! Are they talking about just PVA or do SBR and Acryllic have this affect aswell? Cuz you're options would be severely limited if you use cement adhesives if that's the case.

I'm keeping my fingers crossed that I haven't just said something completely thick!
