Adhesive thickness - Mapei Keraflex - Shower - Tile Advice

[darry]

Hi, I've got to the shower tiling stage! (after I tape walls).

I've now got walls, and I'm going to tile onto the Marmox boards/mapgum WPS (pics below), and reading the forums Mapei Keraflex Maxi S1 seems a good choice so I can take my time. What I'm not sure on is the adhesive mm thickness to use, the tiles are ceramic 40cmx20cm, any advice appreciated. Thanks.

I would recommend an 8 or 10mm trowel.

Out of interest, how have you sealed the marmox to the tray?

Thanks Geoff... for sealing to the tray I'll be using Aquafix self adhesive tape which I bought for sealing the boards, or mapei tape that came with waterproofing kit.

I agree 8 to 10mm trowel will do it. It's a shame you have needed up with a large gap to the tray at the bottom.

It's not that big... that's where the original plasterboard came to, so just followed the lines. The tray is 'lipped', so the tiles will go over the lip covering the gap.

Use the Mapei tape & gum to fully tank down onto the tray

Thanks, but Would the Aquafix tape be fine too? it's a butyl rubber self adhesive tape, same as marmox tape.
