Whenever I try to force Polyfilla into a screw hole prior to
redecoration, it is hard to get the stuff IN the hole, because the air
inside keeps bubbling out! I keep meaning to find a way of getting the
filler into the hole, but has anyone got a trick here?
I've used a flexible decorator's sealant injecting as described above,
when it sets it usually leaves a slight indentation that you can then
fill with a fine surface filler, works a treat for me.
Use a drill bit or similar shaped thingy, slightly smaller diameter than the
hole, to poke it in with. Also, I find Artex better than Polyfilla, and way
cheaper, and it's also great for sticking coving up :-)

No, the problem is the air inside the hole. Take any hole (within
reason!). There's air in it. Now try to force Polyfilla in. It
"hydraulics" back out again! It's the devil's own job to get some to
stay in the hole. That said, I have bought a cake icing decorating kit
for 69 pence from Wilkinsons and this has a pointy nozzle with a small
hole at the tip. I intend to poke a drinking straw through the nozzle,
fill the bag with filler, poke the contraption into the hole so that
the straw bottoms out, and s-q-u-e-e-z-e!
Normally, I wouldn't make such a song and dance of it (but if I did,
my choice would be Ian Dury and the Blockheads' "There Ain't Half Been
Some Clever Bastards"), but I have quite a number of these holes to
fill and I want minimal after-sanding when the filler has set.
I'll keep you posted as to the efficacy of the process - for which
Mike P must take the credit, as he was the one who gave me the idea in
the first place.

Whilst the trapped air is the root cause of the problem it can be
overcome with a stiffer mix that resists the tiny bit of air pressure.
Polyfilla does need to be quite stiff, certainly too sloppy if there
is any hint of dripping or moving under it's own weight.
With a stiff mix you can treat it a bit like plaster. Wait for it to
set a bit then use a wet trowel to remove the excess. With a stiff mix
you don't need to overfill either as it stays where it is put. Needs
virtually no sanding afterwards just a quick sweep over with a sheet
of medium to de-nib more than anything else.
