Hi all

Just started a bathroom on Thursday with mainly plaster walls, but a stud wall the customer has had built is marine ply.

Without thinking I primed the lot with BAP APD which I now realise may have been wrong for the ply.

I am using BAL SPF for the plastered walls - can this be used on the ply as well? BAL powerspec recommends BAL Flex.

Any advice gratefully received

cheers

Hi Kirsty, is the plywood in a shower area or outside it ?....Gaz

Hi Gaz

It is inside the shower area

Thanks Kirstie

Kirstie, first of all the plywood should have been tanked, now you have primed with APD it is ready to tank with WP1 kit.
Once done SPF is fine, and microflex grout.....Gaz

BAL Adhesives - Products - waterproofing kit

Or a quicker way is to use a tanking membrane.....


Wetdecs wet room supplier, wet room shower tray, tanking. waterproofing from leading wetroom company. - Waterproofing

Thank you both for your advice, its really appreciated.

Just need to sweet talk the customer into paying the extra cash now!

Hi kirsty,most customers if you tell them what/why and which they`ll agree to it as they dont want leaks coming through sealings or having to redo again when it fails
