Quick fix silicone sealing (new over old) question

[ElCI]

Hi all
Apologies if this is a stupid question.
I seem to have a leak from my shower cubicle.

Silicone sealing by previous owners is a riot. I'll probably need to scrape out fully and re do from scratch but due to various reasons it'll probably be several weeks at least untill I'm able to do this.

As a quick fix I've just applied a generous amount of silicone around the shower base and door to hopefully stop any leaks in short term. I haven't removed the existing silicone, I've just added around it/ to areas that looked particularly poor. I know this isn't the done thing but is there any actual issues with it (ie can it cause any issues with existing silicone etc? I assumed that the issue was it looks terrible but now I've put it on I just want to confirm I've not potentially opened a can of worms here)

Thanks all

As a short term fix, it is better than nothing.

BTW, many shower enclosures are designed to be siliconed from the outside only. Not all, but many. Unfortunately, many people don't read the instructions.

Where was the visible leak? Photos will help

Basically the leak was seen in room below, there was (a fairly small amount of ) water coming down the wall when shower was directly aimed in the left wall during cleaning. I've not long moved in,from what understand there was a leak previously. Looks like previous owner tried to cake on silicone to fix but had gaps in it. There's also some grout missing between a couple of tiles that I'll need to sort.

Basically, I have low confidence that it's watertight, think I'll need to scrap out all silicone and re do. Also need to regrout certain bits. But ultimately, need something to get me through next month or so at least as a quick fix. My preference would actually be to just replace the lot (while new enclosure and tiles or wet wall)

No effect with the existing no - will you be able to ensure that the silicone on top provide a sealed coating top to bottom without gaps, may be a harder one to judge. I presume this is at the wall join with the shower tray?

When re-doing it, cut out as much of the old silicone that you can with a guarded razor blade, then use a solvent to lift as much as possible that remains - I use that green brush reviver from See and Screw (B'n'Q) and leave it for a bit of time and then add more to soften it, than scrape it off. Just remember before adding new silicone that the area needs to be squeaky clean with no residue of anything, especially water.

Use a hairdryer to heat the area nice and warm as there may be water gathered down in the join if its been leaking and you want to get rid of that if possible.

Bit late now, but i'd use CT1 as a temporary bodge. It seems to stick to anything, even wet surfaces.

Yeah - the trouble with that is when it comes to getting it off.
