had mentioned it before.

It knocks Polyfilla into a cocked hat - this stuff is creamy and very
easy to work with - I had to put in a fillet 1x1cm the length of the
backbox side and despite the bulk, it goes in, stays in and allows to to
smooth it to perfection with a knife with no cleanup or sanding needed.

Didn't even drop any on the floor.



So that's my tip for the day

I agree, bloody marvelous stuff, I don't use anything else.

Microspheres. I have to say the TS own label version I used was anything
but creamy, and actually pretty useless. The tubs of pre-mixed patching
plaster work in the same way IIRC

I've used the Sika/EverBuild version from TS and it was fine, the tub
felt empty before I started using it, are those spheres full of helium? :-P

Make you wonder why Polyfilla still exists. Red Devil cost me all of £7

Hmm. This came from TS but is the genuine label.

All the others I've had, from Wickes own to Polyfilla all seem to dry
and crumbly or they shrink badly on drying.

Any good for fixing cracks between plasterboard sheets, though? Only thing
I've found that works is a good decorator's caulk - but it shrinks so
needs several applications.

What i need is something that grips well, is flexible, and doesn't shrink.

A 10 kg bag of joint filler or Artex powder costs £14. Usually I don't
need a filler to be lightweight or fast setting.

Yes, I'd be interested to know that, too. I've got cracks in some of my

No but the stuff with microspheres doesn't shrink when it sets like the
stuff you use.

Acrylic caulking is better for suff that moves a bit, it is flexible
like silicone but can be painted.

Decorator's caulk does do the job. But needs perhaps 5 or 6 applications,
so allow plenty time for this before painting. But it does last better
than anything else I've tried. Did my problem ceiling some three years
ago, and it's still fine. All the other fillers I've tried lasted weeks
before the cracks appeared again.

It dries out a bit, but the addition of a few drops of water sorts that out.

The idea that a filler won't crack regardless of the surface it's being
applied to is faintly ridiculous. Something that dries flexible, like
silicone or caulk, will obviously accommodate movement but can't be
sanded or matched to any non-flexible surface like wood or plaster

Eh? Most would paint a plaster ceiling. And I can assure you caulk does
give an invisible repair, under paint. Just takes longer than I'd ideally
like to do properly. You don't sand it - just use a decent filler 'knife'
like a Fugenboy.

It's funny stuff - like expanded polystyrene in whipped cream format!

Used some more yesterday and painted straight over an hour later.

It's the first filler where the knife has rendered it dead flat and
flush, with no overspill to wiper or sand off and when painted it
remained flat.

If you fill the gap between the filler and the lid with screwed up
plastic bags, it stops it drying out

It takes a while to harden, that's for sure - but seems to accept paint
quite quickly.

To answer your question, I have just poked some (unpainted, 10mm holes
filled).

It seems elastic - it had some give but sprung back.

After reading the glowing reports of this stuff here, I'm going to give it a go; on a concrete windowsill (exterior) which needs some filling before painting.

Question: should I pre-treat the rather crappy, powdery substrate with PVA solution before applying it, as I would with plaster or sand/cement? If so, would I apply the Red Devil while the substrate's still damp or let it dry out first?

It knocks Polyfilla into a cocked hat - this stuff is creamy and
very easy to work with - I had to put in a fillet 1x1cm the length
of the backbox side and despite the bulk, it goes in, stays in and
allows to to smooth it to perfection with a knife with no cleanup
or sanding needed.

After reading the glowing reports of this stuff here, I'm going to
give it a go; on a concrete windowsill (exterior) which needs some
filling before painting.

Question: should I pre-treat the rather crappy, powdery substrate
with PVA solution before applying it, as I would with plaster or
sand/cement? If so, would I apply the Red Devil while the
substrate's still damp or let it dry out first?

I guess that is similar to "car body filler", I tend to get mine from
eBay. From the ease of sanding, I assume that "car body filler" has a
fairly high content of microspheres.

Yes, a basic polyester resin. The TS version is not an easy sand type
and seems higher in resin content. Actually not the ideal consistency
for a filler but cheap compared to Halfords!
