No More Nails or equivalent if you never want to remove it without
damaging it.

Otherwise drill and counterbore, and make plugs from a piece of MDF.
Screw the the cill to the wall and then fit plugs and sand over the
top. These can be drilled out to gain access to the screws if you
ever want to remove the cill.

Cills usually go outside, window boards go inside.

In either case MDF is unsuitable as it is very prone to damp and will
expand, bend etc

I hope you're wrong. I have great hopes of putting a newly painted
corner unit made from MDF into my bathroom. I'm counting on several
coats of paint to protect it from moisture.

====================
I think you're safe with MDF. Wickes and other such places sell ready-made
window boards - 1" with bull nose and ready primed. They must have faith in
their product.

Exterior-grade MDF has been available for a quite a while - at least
fifteen years. I remember when it was first introduced, my Dad (who
works in the timber industry) had an un-painted/un-varnished piece which
he left out in the back garden for a couple of years by way of a test
and it suffered no ill effects, other than attracting a bit of surface
moss/mould.

I don't know what it's bonded with to make it weatherproof - probably
some variety of nasty chemical or other!

It will last as long as the paint remains impermeable. Then it will turn
into cheese. You can certainly do this, but I'd be wary of it.

A much better material is Valchromat - MDF with extra resin content,
making it both water-resistant and also pre-coloured.

I'd be amazed if an MDF outdoor sill lasted more than a winter or two.

Just for everybodies reference

The "sill" or window boards will be on the inside not outside..

MDF is totally fine until it gets sopping wet.

Then it turns into soggy cardboard. However it is impregnated with
resin, especially at the surface. Watch out for end grain though..that
CAN soak stuff up. Several coats of paint are advisable.

It bends a lot less than softwood or hardwood.

Not to most people, nor my dictionary for that matter.

[Collins]

Cill - variant spelling used in the building industry for sill (senses 1 - 4)

Sill - 1. a shelf at the bottom of a window inside a room

No entry for window board

L shaped steel straps screwed to the underside of the board and then screwed
to the wall work well. The straps are then hidden by the wall finish.

MDF sills should be avoided. I know from experience that the surface
degrades too quickly in real world use to be a product of any serious
quality.

If you get a new build, the skirting, architraves and window boards
will all be MDF.
I suspect they are durable enough if painted properly.

Yeah, cost cotting all over

well, mine wasnt. Maybe others will be luckier. I guess I just dont see
much sense in installing something that will be a mess in 5 years when
you can have real wood that will look good next century.

Enjoy your mdf!

They're not MDF, or at least not the same interior-only grade of MDF
that's usually known as "MDF". They're more likely to be a cement-bound
wood fibre board, like Versapanel. Some of these uses also have fire
resistance requirements that the cement boards meet and plain MDF
wouldn't.
