Got bad black mould on bottom white sealant in shower cubicle - is
there any difference between the anti-mould sealants and if so which is
better.

Also I've seen that a tape can also be used which looks a lot easier to
do. Any good?

Pointers to a good video on applying sealant would be good. Including
tools and removing old.

Thanks

Just wipe it down with bleach occasionally. And use a daily shower spray.

Or if you are too lazy, learn to love its artistic effect.

My experience with any of the tape products is that they are only as
good as the glue or double sided tape. It's the glue that fails over
time allowing water behind the tape which in turn destroys more of the
glue holding te tape on. Furthermore if a tiled surface the grout lines
are probably recessed from the tile surface. The tape will not mould
into a 1/8 inch recess and so on every vertical grout line there is the
potential to let in water behind the tape.

With sealant it's probably better to get a 45 degree profile on it
rather than a concave profile as you may get with smoothing off with
your finger.

Invest in some profiling tools

Fugi, Fugiboy etc. tend to be the brand name for these sets at £20 but
the equivalent can be had for a fiver. Mine cost under a fiver from Lidl
when they once had them in stock.

Bleach works but in my experience only if you catch it early enough.
Last year I tried to treat some black mould that hadn't been treated for
maybe 10 years. A quick wipe down with bleach didn't do much and leaving
the joint wet with bleach* for 24 hours only got rid of around 75%.

*rolled up paper towel was pressed on top of the joint and then the
paper towel soaked in bleach and not left to dry out.

It was claimed that the Modified Silane sealants were supposed to
perform better in this respect, but my own results have been mixed. Yes
they do stick better, and can be over painted, but the are slightly
harder to work, and can still go mouldy in particularly wet environments.

So basically pick a decent brand name sanitary silicone and hope for the
best!

Probably not as good as silicone - chances are water will get past it at
the grout lines.
