Hi thanks for your reply , is THE I skimmed weight for 9.5 mm thanks .
Also would it be beneficial if I was to recover over the 9.5mm with 9.5mm or would you chance the 9.5mm thanks again

The skimmed weight has the weak point between the plaster and the board. Wouldn't matter if it's 25mm board it would still be 20kg (including adhesive and grout) total.

Not sure if the 32kg unskimmed is 9.5 or 12 though.

@Paul C. Is the guy who has most recently studied BS he might know.

Its doesn't say. So I would think both will hold the same weight. One thing it does say though, is if screwed to a wooden frame, the thickness must be a minimum of 12.5mm.

Its all in BS8212. you can only tile onto the 9.5 mm on drylined walls with dabs at no more than 450mm apart, but the 32kg's per sqm limit, applies to both the 9.5 and 12.5 boards.

So if its a stud wall, you have some rethinking to do, but would advise that something like Marmox, Deltaboard, Wedi etc would be your safest bet.

What centers are the studs set at?
You can overboard with backerboards, using tile adhesive and mechanical fixings.

Would have to check , I was thinking of going over the 9.5 with 6mm or 9.5mm again , it's a stud wall just seems a shame to have to go over it again ?
Was going to 12.5 it but just did like for like , my fault really

M2 and sqm is the same meaning per square metre

It is the same mate.

Per meter squared = per M2
For square meter = for sqm

Same thing just different way of saying it.

Which is the Italian way?

10 sqm?
