hoping I’ll get sing replies to this one in tiling since I’m guessing a lot of tilers have had to fit trays.
A couple of days ago I laid a 1200x800 Stone resin shower tray, the flopping heavy type. It went on a completely level 25mm ply base screwed to joists. My instinct was to lay it on construction adhesive since no levelling was needed, or tile adhesive, but I was a good boy and did exactly as the MI said on a 5-1 mortar mix.
Since then I’ve put the no more ply boards on the edges but not yet finished the walls (which will be Beton Cire, a waxed concrete).
Coming today back to the tray I’ve noticed the mortar is very crumbly, the bits splodged on the edge etc you can crush in your hand.
I’m now worried over time and with the small movement of a timber floor it’s going to crumble away underneath and eventually fail.
I wish I had gone with my gut instinct and used flexi tile adhesive. To pull it out now will be a bit of a nightmare but possible. Am I worrying about nothing?
