Tanking and shower tray with adhesive upstands

[grahamgibson]

Hi,

I will be installing a Daryl low lever shower tray which comes with an adhesive upstand (which is thin, so won't need recessing into the walls). I'll also be tanking the shower area using the BAL WP1 tanking kit.

My question is - should I tank the entire shower area, including walls and floor then fit the tray and tank again over the upstand OR should I just fit the tray first and tank the walls down over the upstand.

The first approach strikes me as most thorough and bullet proof, but possibly overkill.

Thanks in advance.

Cheers,
Graham

Is should hope that no water gets under the tray That is the reason you are tanking it in the first place, so no need to do under there.
