Do I need to silicone the whole lot?

I'm about to re silicone my shower tray (sealant remover on as I type), so thought I would tackle this niggle on the bath also.

Is is possible to add some silicone to seal it up, or do I need to remove all the silicone along the tap end and redo it all?

I've never siliconed before but know silicone will bond with silicone, as long as it's dry.

Best remove ( sharp wood chisel is ideal) if it’s split then original surface was not clean enough ( or bath has dropped
).
 
The gap is the clue....

You may have sagging. (not unusual)

Always remove old silicone. It debonds eventually.
Clean up carefully and make sure to use a degreaser (meths if suitable?) before applying new silicone.
But the best stuff you can afford.

If you have never done it before, watch plenty of videos and do some test runs.
Have plenty of paper roll on hand when you do.

For the bath, fill it full first.
 
Thanks. I don't want to do the whole bath, so is it ok to do up to the corner?

I am doing to the corner, sealant remover on, although it doesn't appear to work that well compared to the video I watched. Thanks for the tip to fill the bath. I may get in it too :D.

BTW this is the shower tray pre removal and after. There was gap between the top of the silicone and the tile/grout. They seem to have lined the tray up with the join between tiles (assuming there are tiles below). It's leaking into the garage below. It's a raised tray so before I rip the tray surround off I thought I would re silicone and see if that fixes it. Or would anyone just recommend viewing under the tray first?

I'm going to de mould, meths, make sure clean and perfectly dry before proceeding to make a mess.

I'm no plumber so....

Leaking?
Shower trays are lipped. (or mine is) so that you tile over the lip. This means the silicone is not the only line of defense for leaks. Perhaps check for leaks elsewhere. (Trap/Drain piping/ Shower supply?)

Mould and hair dye (ARRGGHH) is an absolute bastard to remove. Soak it in toilet bleach (the thick stuff). Works wonders.

A tip for siliconing for amateurs like ourselves is to use masking tape. I find it helps get a straight line where visual sighting is important.
 
Sorry I seem to have moved onto the shower tray. The size 16 profile tool only just reaches the tile above in the corner, so that is going to be one big ol pile of silicone. It's like the tray has dipped a bit in the corner. Could this be due to previous leaking causing damage underneath? I don't really mind a thick bead of silicone as I'm looking to get the room re done at some point. I'm wondering if any tool exists that isn't a 45 deg angle, so would be taller than it is deep? If not would a curve be better? Also if I use the 16 should I try to use reduced sizes as I come across as near the shower panel as there is hardly any gap near to the panel. I'm not sure how I would do this though without leaving an obvious mark in the silicone.

It kinda bonds but sometimes you can pull a bead of silicone of an older bead of silicone with relative ease

I have those Fugi tools but often use these

They offer 16 different angles/profiles
 
Dilute some fairy, dip your finger in the fairy and run it down the silicone. Those tools are not always useful.
