Barney12 Posted March 15, 2018 Share Posted March 15, 2018 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? Dirty picture: Link to comment Share on other sites More sharing options...
MAB Posted March 19, 2018 Share Posted March 19, 2018 (edited) 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:- https://www.screwfix.com/p/fernox-ls-x-leak-sealer-50ml/23614?tc=CT2&ds_kid=92700020969989289&ds_rl=1249799&ds_rl=1245250&ds_rl=1249484&gclid=EAIaIQobChMIu_mSwJr52QIV6L_tCh1XXAcjEAQYASABEgL_p_D_BwE&gclsrc=aw.ds&dclid=CJ6Er8Ka-dkCFRES0wod0sIOCQ Edited March 19, 2018 by MAB Link to comment Share on other sites More sharing options...
Barney12 Posted March 19, 2018 Author Share Posted March 19, 2018 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 Link to comment Share on other sites More sharing options...
Nickfromwales Posted March 19, 2018 Share Posted March 19, 2018 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. Link to comment Share on other sites More sharing options...
