Somedays its just seems to be one thing after another since we moved
into this new house. We had heavy rain last night and found the
conservatory was leaking. Fortunatly it has a tile floor so no damage.
It looks like some of the external rubber beading on the perspex roof
has shrunk a bit (the conservatory is over 10 years old). I was going
to fill the likely suspect areas with a couple of runs of clear silicon
sealant. Is this the correct stuff to use? I noticed that unibond make
a specific black coloured gutter sealant. Would this be any better or
is it just black silicon?


It's a bituminous, non-setting gloop. In some ways, it is superior to
silicone in this type of application, because it stays put for a very
long time. But it can't be smoothed down to a nice even finish as well
as silicone.
