Polystyrene Coving ,,,

Proper plaster coving you can easily cut with a saw?

well that was helpful never tried but I would have thought a sharp knife

Just snap it by hand until it fits in the bin, then get some decent plaster stuff.

Yeah, there's always one ...

I tried a sharp craft knife, and it's ok until you get a little way in, then it sort of stops cutting. hard to describe.

Ah. Always TWO then ... Planks ...

I've always cut it with an old handsaw, the coarser the better

How did you make the hot wire saw - I've got some to cut as well...

I use a a 10" cooks knife, the damn thing is sharp enough to cut glass fibre insulation without "sawing".

If the wife finds out she may not like it. 8-)

A sharp knife. You're going to have to use a filler of some kind on the joint anyway before painting.

and your it :-)

fine handsaw, and wipe some filler into the join where needed (it will be). I've used paper-covered polystyrene coving and it looks fine when it's decorated.

You need a knife(Modellers) with a round edge rather than a flat blade(Stanley) for polystyrene.

Do people still buy that sh*ite?

Plaster type coving is quite cheap compared to the polystyrene rubbish.

I wouldn't use it at all. Apart from the problems it can cause in a fire (poisonous fumes) it always looks what it is even after painting. It's not as though the plaster stuff costs much more.

My uncle spent a long weekend experimenting with my dad in developing a hot-wire saw using his car battery as a 12v source.

He then drove home.

He was on the phone to mum & dad to say that he had just got home safely when he was quoted as saying "Ah, I've got to go now, the car has just burst into flames".

why would that make the car burst into flames? are you suggesting it damaged the battery?

I know what you mean; doesn't the fact that you get a clean leading (ie visible) edge mean that's OK though?

Polystyrene can be put up with wallpaper paste very quickly. Once the joints are filled and the whole lot painted you cannot tell the difference. And much easier to remove when the female of the house decides a change of decor is needed

I think you can - the texture still shows through. Although the paper covered stuff may sort that. Also the fact that it bends to fit is often a giveaway.

I tend to think of coving as a fixture rather than a wallpaper.

You can,you never seen peoples thumb&finger indents on it?

And much easier to remove when the female of the house

Id like to think coving was staying as a feature
