How can i improve my preparation

[Waluigi]

Yes, I’ve used it. No different to any other foam board IMO

Has anybody tried this

I’ve seen it at bal HQ on a training day, basically another version of hardie backer I think. But cuts easier.

“Water and Mould resistant”

Waterproof please if it’s on walls. Otherwise it’s pointless.

Do you know of a waterproof board?

All foam boards are waterproof.

The likes of Hardiebacker, Aquapanel and the new Bal board, it seems aren’t waterproof.

ETAG 022 Part 1 says that all new builds must have waterproof boards in showers, or tanked. The Bal board is pointless IMHO. Develop a decent waterproof board instead, please

The inner core of boards such as Wedi are waterproof i believe,
but the face is coated with cement which is not.
As this is the surface that the tiles are stuck to it can degenerate.

 

[Waluigi]

Can it?

I’ve never seen it.

You’ve got Orbrey, Wedi, Dukkaboard, Jackoboard, Marmox, all in the form of wet room formers that don’t require tanking on the face of the board.

All are considered ‘waterproof’

 

[Flintstone]

Kerdi board is the only board that is water proof in the core and on the face

Good info, I didn’t know that.
