Gripfill dry time

[jayc89]

I've stuck a bit of plasterboard to the top of a window reveal, braced it with a couple of lengths of timber and screwed into battens where I can. I'd general use a PU adhesive, which dries in 10-15 minutes but I'm fresh out.

 

How long will I need to leave the bracing up before I can attend to the sides? (please don't say 24 hours )

Gripfil is pretty much instant unless you are holding a lot of weight, 30mins should be more than enough
