SEALING A SHOWER WASTE IN A STONE RESIN TRAY

[elecnewt]

I have been recommended CT1 as a sealant for a shower waste.
Is it recommended to apply sealant to both sides of the Neoprene rubber seal that is on the top surface of the tray and to both sides of the Neoprene rubber seal that is on the underside of the tray?

Never used the stuff before. But I have a tube waiting to be used. I use mapesil

Thanks for the response, Harvest Fields.
Do you apply the sealant to all the four surfaces that I listed?

I usually throw the top washer out the window and just use sanitary silicone underneath. And just use silicone on top of the washer for underneath the tray. Never used ct1 either but know people who swear by it. People will have their different methods, if it doesn't leak it's the right way!

Thin bead between rubber and trap. Thin bead between rubber and tray and thin bead around top of tray and trap connector. DO NOT USE CHEAP SILICONE.

As above. I never use the top washer and have used Dow Corning silicone for years with no problems

The rubber is included for a reason. In my opinion.

Me personally if it's got a rubber washer no sealant on that part aslong as the face is smooth and flat

Always mastic the top ring / the bit showing

Waz the top washer just use good quality silicone.
Thin smear of silicone both sides of the thick black washer underneath.

Why seal the top ring? Where's it gonna leak from there? You only need to seal the trap to the underside of the tray with whatever you intend using, silicone, ct1 or whatever. Don't overdo the sealant and don't overtighten it, and it'll be fine😉

Some attach with self tapping screws so can get around

On a stone resin tray?
Never seen that before tbh, but I'll take yet word for it.
But yeah, the ones with the fixing ring and four screws in, silicone for sure. Just saying, that's all😀
