Going to put up plaster coving into our bedroom. Are the external corner
cuts the same as internal ones? Did my daughter's bedroom several years ago
but that was just a square room, all internal cuts. Our bedroom has an
alcove in one corner so will need an external corner. I have got one of
those cove cutting jigs, the plastic triangular which sits on the coving
then you just cut keeping the saw on the jig.

Thanks

You use the same jig but turn it 'upside down' IYSWIM. The lugs on the jig
that locate on the coving edge go on the other edge and cut as normal. Have
you still got the instructions for the jig? It will tell you on there how
to cut int and ext corners, but you can do it with that jig, try it out on a
piece of scrap first to get the jist. You will probably find your corner
isn't square anyway so you will need to fill in afterwards, filling an
external corner requires more care than an internal one if you want it to
look good.

When cutting an internal mitre - the offcut that is left will have an
external mitre on it so you can use that.
Don't turn it upside down though as it will go pear-shaped :)

I noticed the flexing of the plastic jig so I glued a brace inside. How
did plasterers make these mitres before this kind of DIY jig arrived?

Thanks guys. Another question. Need to 'but' two lengths together. Do I
just 'but' then together square or cut a 'normal' mitre and join like you
would skirting / dado rails?

I've done it both ways before and found that the easiest joint to cover up
is a mitred joint, even if it does crack slightly it will still not look so
noticeable as a butt joint.

If you have not already bought the coving consider 120mm PAPER covered
polystyrene coving instead of plaster.

Its cheaper .........lighter.......easier to fix with adhesive and 2" panel
pins......and....... you can cut it easily with a knife.........you really
cant tell the difference once painted.

As for the corners you need a coving mitre box......about £6 in B and
Q.......cuts inward and outward corners perfectly.

Just did my lounge and it looks fine.

Best of luck

I did go for the paper covered polystyrene coving. Agree with you on all
your points. Easy to cut, handle and a doddle to put up. Have applied 2
coats of paint and the joints are invisible. I ended up doing a butt joint
as recommended on the coving packaging, and filling with filler.

Just need to paint the walls and put down some laminate floor now!!! Oh,
the joys of decorating.
