Tanking a separate shower

[Rust]

Hi,
I'm looking for some advice on tanking a shower.
I have a 1400x900 resin shower tray in an enclosure with three plastered walls - one wall is stone and two are studwork.
I've bought the Aquaseal tanking kit and I just want to know can I, or should I, run the tape that comes with the kit onto the shower tray itself, by 10mm or so, then apply the membrane, creating a complete seal between wall and tray?
Or should I buy something like the aquastrap?
Cheers,
Rust

If the tray hasn't been fitted yet, these are excellent.

Classi Seal Shower Tray Sealing Strip and Bath Sealing Strip - https://www.lowcostplumbingsupplies.co.uk/classi-seal-3-2mtr-flexible-waterproof-upstand-p4074

You can still lap the tape down on to the tray, tile the walls, then cut it back after.
if the walls are plastered, in comparison to other substrates they'll not carry much weight.
What type of tiles are you using?

The walls are plastered, so I know I'll be limited to 20kg per sqm, but I haven't chosen tiles yet (tripping over samples though!)

The tray hasn't been fitted yet, so are you saying I can apply a flexiseal of some kind (like your link), install the tray, then lap the tanking kit tape over the flexiseal and onto the tray, then apply the membrane?

If so, I like the sound of that - a belt and braces approach. I was just wondering if simply lapping the tanking tape into the shower tray and tanking was sufficient/a good idea.

Thanks for your reply.

I'd definately apply the classi seal behind the tray and against the wall. I've seen them save clients from what would have been major disasters.
Yes then put the banding on the wall and lap over shower tray and apply tanking membrane over wall and tape.

Thats great, thanks for your help 3_fall.

Is classi seal a good product? I've been looking at the Sealux Aquastrap (essentially the same thing), although you can only use a neutral curing Silicon with the Aquastrap.

I use classi seal.

I use classi seal.

And can you just use normal Silicon with it?

You'll be covering the seal with the tanking band and membrane anyway, they won't come in to contact with each other.

Good point. Thanks
