Hello,

I used to use Toolstations' "glue screws" cartridge adhesive but it
seems they have discontinued it. So I was using their "gun a nail"
instead:

This is solvent free but seems to have gone up in price recently. I
see they also sell "instant nails" from the same manufacturer:

Is there much difference between these or can I save some money and
use the cheaper one?

They are both solvent free, so I presume this means they are water
based?

Can I use them with moisture resistant plasterboard or will the fact
that it is moisture resistant stop it from working with a water based
adhesive?

Would a water based adhesive fail when wet or once cured, does it not
matter? Would I be better using a solvent version?

Thanks,
Stephen.
