Hi Guys,

Can you please give me some advice about shower waterproofing.

I will be installing a shower enclosure in my upstairs bathroom , one wall is a solid wall (concrete bricks) another wall is currently a plywood box with all the pipework inside.

- How do I waterproof the solid wall before tiling? I will remove the old plaster off that wall first, then do I just apply a few coats of waterproof material and tile, or do I need some covering boards?

- the plywood box, I planning to rebuild it using hardybacker, do I need to waterproof hardybacker in some way before tiling?

Thanks for your help!

I would say its certainly worth tanking under tiling as the grout can become porus over time.
I have a bit of this left over from another job, so im thinking of using it.

Not sure if its suitable though, but it does say you can put it on with a brush, not sure how it would work on plaster board. I might have a test with an old bit of plasdterboard first.
 
Hi,
It is always a good idea to tank the walls within a shower enclosure. This video shows you how to use the tanking system.

I would install fir strips to the wall then install aqua board. You could also install a stud wall, insulate and apply aqua boards or backer boards. Tank as normal and tile.
