Tile Adhesive Late Q's! - Tile Advice

[zebedee23]

H there, to state the obvious, I've joined for this Q! but would appreciate the advice

I'm currently about to tile a 10sqm, internal concrete slab floor (new build, slab is approx 18mnths old) a couple of sq mtrs will be sun facing. Porcelain tiles are 10(ish)x450x450mm and will be back buttered.

The floor HAS been primed using NX Primer (Norcros Primebond) and I have, still in the bags! NX Rapid setting adhesive - suitable for Porcelain, but is C1 not C2.

I don't want the tiles to release/fail at all! but C2 appears to be the obvious choice for low absorbancy tiles, will the above adhesive be ok? I purchased as it said 'suitable for Porcelain' (I'm DIY) and as above, it might've been better to say 'suitable for Porcelain, but the other one is better!'

Thanks if you've any advice on the above,

Not an adhesive I’ve used before but if you have any doubts contact the manufactures direct!
Most C2 adhesives would be suitable considering a porcelain tile ( low absorbsion)
and your heat factor.
Check your tile for bring porcelain as 450x450mm is an unusual size.

I would use a c2 minimum but c2 s1 is better

Thanks, manufacturer has advised C1 for the application is suitable - hard tile and solid floor, bond strength would be the same.
