Doesn’t do what it says

I bought this instead of plaster to fill areas around 20mm deep around a hole in a wall. It doesn’t set unless you use very small layers.
Great filler but takes time to harden.

Best general purpose filler I have found. Lightweight, so it doesn't sag. Fills deep holes and easily sands very smooth. However, it takes an absolute age to harden. So you need to be patient. Allow two days for a 10 cm deep fill. Still, I suppose a thin layer of emulsion paint takes two hours to dry, so it isn't surprising deep gap polyfilla takes so long.
Does not dry

I got this product as it suggests can fill up to 20mm deep gaps and is dry in 1-2 hours. As others have commented, dry time is much much longer. Suggest anyone looking to fill larger holes in a reasonable amount of time to look for another solution!!
Doesn't slump in deep holes but doesn't dry either

Although it says on the label it fills holes in one application, five days after filling around new power sockets it is still weak and crumbly. I would have saved time if I had done the job in small stages (as it says in the detailed directions) and although non slumping, ordinary filler would then have sufficed..
Can take a long time to dry

Nice texture and works nicely out of the tub, and it says that it dries in 1-2 hours, but that would only apply to a thin layer. Yet this is 'Deep Gap' Polyfilla. I wanted to fill in a hole left by a double socket that I had removed (back box as well) and even after two days a partially-filled hole had not fully hardened. I reckon it will take at least a week to fill this hole!
