I always seem to end up with half used tubes of silicone, gripfill, bath
sealant etc.

Anyone have any tips on how to keep the stuff from going hard & blocking up
the nozzles? I know they supply a cap, but it always seems to be too small
once you have trimmed the nozzle.

I read somewhere about using 4" nails?

Any tips?

Er, yes - use 4" nails!! Works a treat.

(Actually, use different size nails depending on the bore of the nozzle
you've cut)

Some of these tubes come with nozzles with a threaded cap, which are
good. When I'm using any of this stuff, and a tube runs out in the
middle of the job, I always transfer the old nozzle over to the new
tube, thereby maintaining an identical nozzle size and not wasting the
sealant otherwise left in the 'dead space' of the old nozzle; this
leaves a spare unused nozzle, which if it's a threaded type, I'll hang
on to for future use.
