If the bathroom is lined with aqualine/ water resistant cement board product, do you need to put 'spacers' between it and seratone or can you just glue it on? Diagrams that I've found indicate you need a 6 mm gap between wet-floor vinyl up the wall and seratone/ hardiglaze overlapping it. It shows diagrams of using battens but only on bare studs/ nogs. What to do?

Use battens. It allows air circulation and the timber can dry out. But use marine treated timber anyway.

Say what? Are you saying fix battens over the existing linings?

What is marine treated timber?

That's the dilemma, primed aqualine is water 'resistant' - what is a floor?- we don't put battens on floors when we put on tiles or lino? we seal the joins. Does aqualine breathe? if water does get into the joiners it can potentially bead-sit on the bottom batten.

Marine treated timber is treated to H6, suitable for wharf piles, sea walls and other saltwater applications. Probably a little excessive for behind a shower.

I would glue the seratone straight onto the existing lining you described. It Is tantalised hardboard and is virtually bullet proof. I recently stripped out a bathroom I lined with seratone 20 years ago. There has been a leak inside the wall and the timber had all rotted completely, the seratone was perfect, even after having been glued to wet and rotting timber for probable years.

Seratone is not " tantalised " , it is oil tempered. The reason for the 5mm gap the poster asked about is to prevent moister rising up the back of the seratone sheet. This is usually achieved by rebating the walls to recess the shower tray.

Yes, that's correct,I was wondering just where the wharf timber went in the shower.

It's just me being super cautious. I cut the battens myself. You still have to prime them so the glue adheres properly.

Are you serious?

Yep. Although, I must admit, it's been a while since I last did it. So things may have changed in the "glue department" since then.
