envelope cutting for wetroom tray

[trusz]

I'm installing a 1400x900 tray former from Maxus.

I plan on tiling over and envelope cutting for the falls in the tray. One thing I'm not quite sure about are the edges of the tray.

Where the tray is drilled and screwed down, the is about a 40-50mm flat edge then the tray falls down to an offset drain similar to the one pictured here:


Do cuts need to be made along the edges between the falls and the flat edge? If I did that, there would be thin cuts around the edge of the tray where it meets the wall, which wouldn't be great.

I was thinking of just extending the envelope cuts from the drain, right up to the edge of the tray and build up a little extra adhesive underneath. As long as there is a gradient and full contact, would this be ok?

Has anyone else tiled a tray like this? How would you go about it?

Cheers

As luck would have it, I've done one of these today, you can see from the pics where the outline of the tray is

Exactly as Bri describes. Here is one of mine in a lighter colour...

Nice work Bri!

So where your diagonal grout lines end, is that the very outer edge of the tray? Also, do you use narrower spacers on the diagonal grout lines?

Yes where the diagonals end is the edge of the tray. I tend to use 2mm for the envelope cuts, simply because that's the width of the blade I use to cut them, the rest of the joints are 3mm.

As I thought.

You've been most helpful!

I have the theory, will be putting it into practice in a couple of weeks when the tiles show up.

Geoff I can't see this pic, is it just me? It won't load on Tapatalk either.
