Shower tray sealing

Potemkin · May 11, 2021

Just fitted a large and heavy stone shower tray onto a mortar bed. I forgot to run silicon sealant around the edges, before tanking with liquid latex and adhesive repair tape from Aquaseal. The tape overlaps onto the shower tray, making a waterproof seal all around it. Do I now need to cut the tape, put silicon sealant in the gap between the shower tray and the wall, and then re-tape and tank? Expensive given the price of the tape, and it looks to me like I have a good waterproof seal now.

No, as long as there is no movement.
Just carry on with tiling.

When you tile, they will also overhang the tray and you will put sealant underneath them; normally leave a 3mm gap. If that’s what you’re doing, then you have two layers of protection and I would’ve thought that will be fine.
