cap for sealant tube.

A small bit of cling film works quite well - at least for relatively short periods.

I normally take the nozzle off and clean it out with a kebab stick and kitchen paper, then screw the nozzle back onto the cartridge trapping a bit of a plastic bag (a kitchen sandwich/freezer one, not a supermarket carrier) between the nozzle and cartridge. If I'm using sealant and only need a small amount I don't use a nozzle at all, just take the nozzle and plastic bag off the cartridge and squeeze a little out onto a finger, then reseal it, because cleaning out nozzles is a pain.

If I've run out of nozzles I seal cartridges with plastic bag stretched tightly over the outlet, and tape the edges of the bag to the cartridge body to try to keep it airtight.

Some PVC insulating tape wrapped and flattened works well and will probably last longer (better seal). Pulls off easily for the next job.

But you've then got to fit a new/clean nozzle though?

I just stick a 2" nail down the nozzle, and it plugs it perfectly ready for use for next time.

Nice tip. Thanks

I use a stainless steel screw of suitable diameter

That spoils all the fun of digging around the fat end of the nozzle with a pointy thing for the bendy silly-cone :)

Good timing - there's about one squirt left in my toothpaste tube, and I have a large tube of silicone which I just started!

My 2p is when you cut the nozzle to size for the width of bead needed, keep the bit you cut off.

When done with the sealant/whatever stick the cut off bit into the end of the nozzle "backwards" -pointy end first.

A bit of gear is squidged out (I wrap a bit of kitchen roll roughly around it til set - keeps it from slarting all over other things) but there is then a good seal.

Next time of use, pair o pliers /moles to remove the end et voila -good to go.

Ah but if that next time you cut the nozzle again for a larger bead, what do you then use to seal that?

There's always been the odd woodscrew or self tapper around of just the right size, that's done the trick for me.

Small beads then! ;-)

How long do you keep a 3 quid tube of silicone going ?! ;-)
