    In a shower, do you remove the shower screen and then silicone tray or do you just replace what you can get at a in situ

    No not if redoing it but i would remove as much old silicone as physically possible and clean up before applying good a sanitary silicone . kop

    I usually remove all silicone especially the important points. You could use a hair dryer to dry the gap and then apply new silicone with with a former. But as above if you have leaks which requires a new install or removal of screen then perhaps I would install new stuff rather then playing with old screens.

    If leaking I recommend removing the screen but normally find customers don't like paying the labour involved as they seem to think a reseal around the tray will do. If they just want the tray resealed I tell them I can't guarantee it's problem solved as I come across plenty of screens that have been fitted with out sealing behind the rails. If they get funny I recommend finding someone else.

    I have removed a few screen in my time and only a handful had been installed correctly. I do not know how people get away with it.

    I wouldn't get away with it, I'd be found out first time the shower was used. Some people are just lucky. :D

    Having done too many to count, and learned a few lessons along the way, my method is thus:
    - remove old silicone UTTERLY (I use a razor sharp wood chisel)
    - remove ALL loose grout
    - make sure you get a good gap under the tiles
    - hoover out properly
    - leave to dry THREE days
    - Return
    - chemically clean tray surface, tiles surface and gap to be filled with IPA (Isopropyl Alcohol not Indian Pale Ale :eek:)
    - fill

    TBH if tile grout joints are cracked it's all an utter waste of time. Although those gaps are tiny, when you add up the linear metreage of 'em it adds up to a sizable hole so not worth doing/getting involved with.

    My experience with that type is they always assume you're taking the **** so it's lost anyway.

    BTW my former for smoothing the silicone are my credit cards. Just had to replace my drivers license as it gave up the ghost. Three corners were all trimmed to diff shapes :D

    It all depends what customer wants to spend. It could be a full day's work to remove cubical, clean and re seal. Obviously if it's really wet behind old mastic it needs time to dry up.

    Normally like to only use mapei sealant which bumps cost again.

    If it's for cosmetic reasons then it's silicone off and replace. If it's for an issue then it's screen out and go from there.

    Pain in the ar$e jobs, but priced accordingly.

    Apologies Matchless. I simply hadn't realised you knew my customers and their habits so intimately... You must be more forward in reminding me o_O

    Just to improve your knowledge even further, and can now sleep nights through feeling MY guilt, in the last twenty years not ONE person has ever baulked at having the job done properly. Not once in the last twenty years have I ever had to revisit either. Obviously this entirely down to lady luck :D
