... is your favourite?
I was in our local independent shed and got some Gripfill. I wanted to stick some backboxes to a wall, get them lined up nicely and then plug and screw when they were stuck.
It took a week to go off!
Car body filler. Takes about 10 mins to go off
I used it where the gripfill failed
I know what's my least favourite: anything from a pound shop. No grab at all.
Gripfill (full fat).
Stuck many wooden blocks to the inside of my concrete garage wall panels to screw the liner ply sheets to and the next day I was able climb up them.
20+ years later they are all still there and with a lot of weight hanging off them (all the slot shelving etc).However, if you use Gripfill as a filler, in thick layers it will take a time to go off.
The test for me is how easy is it to get the stuff off your fingers and *any* tools, even after it's only been on there for a few seconds!
If you had used full fat Gripfill to fix a metal back box to a dry wall then even a few splodges of Gripfill on the back, immediately pushing it onto the wall (and maybe twisting it about slightly to spread it) and left it overnight, I wouldn't think you would ever have needed to also fix it with screws and plugs.

The stuff in the green carton? That's what I was using.
Yeah, I think that's the 'full fat' one I use.
I thing that is an issue with Gripfill is when it's used in any thickness. Eg, if you had put a blob of Gripfill on the back of the metal box and they squished it up against a clean / dry brick wall and propped / taped it there for 24 hours, the next day you could probably have hung off of it.
If you end up with any real thickness that is supposed to actually hold something (as in bond rather than fill) then I would probably either 1) leave it a long time before relying on it or b) use something you mix up that cures using a chemical reaction (two part epoxy, body filler etc).
Daughter has used this stuff:
Another way to speed-up Gripfill when you need a large gap filled is to use a suitable spacer, forming a sandwich.
