Sealing around a shower tray

[Flintstone]

If you are using wedi on the walls, and installing properly - sealing all the joints, then You don't need to tank let alone use a classi seal!

Got enough tanking kit supplied by customer under architects instructions to tank the whole 32square metre main bathroom, and enough to do job at least twice over! Don't know how thick he thinks Im going to put it on? Trowel?

@Localtiler I don't know anywhere over here that sells wedi boards only Kerdi board, but house builders tend to want things done as cheap as possible , the way I propose is proven to work for the situation I find myself in. As I've never done it your way I have to ask how that method copes with shrinkage in joists etc?

I don't know about Kerdi board but with the Wedi boards there are tubes of mastic you can run down framing then install boards using the washers and stainless steel screws, then mastic all joints and corner, then web tapes and flush mastic. So suppose that would take a bit of shrinkage? But I still tank, especially if upstairs or in flats.

Wedi 610 between panels in wet area. Board joints sealed with self adhesive tilebacker strip (the water proof one) then wedi 610 the shower tray into the corner. Intermediate board fixings filled with a dab of 610 on a spatula.

Like this:

@LEE MAC
These systems such as wedi and Kerdi are designed for the job, the correct way is to glue the joints etc etc rather than tank the whole thing. If cost is an issue and your gonna tank the wet area with a tanking kit then you might as well use plasterboard.

Stueys install sounds fine to me.
