Filling PVC cracks

[Jeff Layman]

Anyone got any experience of using this sort of product to fill small cracks in PVC doors?

In particular, has anyone used only part of the product and the rest sometime later? There seem to be several mentions in reviews of having to use it all at once.

Not that, but I have used this

I still have a part tube in the garage, but I expect it's gone off ...

[Jeff Layman]

Thanks. That looks interesting. I had found this, but it's much more expensive:

I've yet to find a tube of /anything/ of that design which doesn't go off after it's opened. :-(

You can slow it down by a combination of cling film first to protect the foil and then aluminium foil tightly wrapped around the nozzle. Barrier to moisture and oxygen which seem to be the most common initiators.

You may still need to replace the nozzle next time around though. The bit at the tip exposed to moist air often has enough exposure to cure.

I unscrew the tip and seal the outlet with cling film and them replace the tip, Store it tip down seems to help also
