Shower Waste Sealing to Tray

[Barney12]

Quick question:

 

is is it wise to put a bead of silicone below and above the tray where it meats the waste to help the waste seal or are the rubbers sufficient?

I have used a thin smear of Fernox LS-X clear silicone based sealant on those seals for my McAlpine shower waste but I removed any excess from the visible side before it cured:-

Thanks @MAB

After watching a few YouTube reviews/guides a decided on a small bead of "plumbers gold". 

First time I've used it and funnily enough it has a similar consistency and smell to LS-X

CT1 all the way. Silicone is not a very good product for this imo, and can skin over and lose adhesion from the underside of the tray.

I Sikaflexed my bath trap in rather than CT1...my post Jan 30 2017:

@Nickfromwales I've read your recommendations for sink wastes but can you confirm, you CT1 both the rubber and the top insert on shower and bath wastes ? 

What do you think of the BT1 product ?

Thanks

The seat / face of where the rubber seal presses against, so on the trap, then put the rubber on, the seal again atop. 
You can’t go twisting these around or the rubber gets ejected. 
Take a bit of practice but always gets the results I need; 100’s of showers / wet rooms done over the last couple of decades (+) and not a single complaint or leak.

Thanks @Nickfromwales, I havent boarded rhe room below yet so can get to the trap from below to keep an eye on it whilst pouring a few buckets of water into the tray to make sure. 

Thank you
