Default DIY home cinema screen

Hi, all.

I've borrowed a projector for the xmas period, and am setting up a
temporary home cinema for the kids ( and me! ). The wall is not great
as a screen, so I was going to make a simple one. I was going to get a
thin sheet of cheap MDF or hardboard, and paint it.

The various AV forums suggest painting the screen material with Dulux
"IceStorm 5 or 6", which can be mixed at any shed.

The question is: how best to apply the paint to minimise texturing?

Texturing is OK under diffuse light, but is rather ruthlessly revealed
under intense projector light.
I've always thought rollers give a rather textured finish, but then
again, brushes can leave brush-strokes too.
I don't have an air gun, but could possibly borrow one. ( cue horrid
orange-peel effects from inexperienced air-brusher. )
I am also suspicious that 'regular' emulsion paints will not work well
in an air gun, for reasons unspecified. Bung them up, or something?

Which would you do: brush or roller, or air gun?


I'd spray it. But I've sprayed bits and bobs before. TBH if you thin the
paint and spray it, the worst that can happen is runs. Orange peel is
caused by paint hitting what you're painting too dry or not thinned
enough - not too hard to get with a solvent based paint, but with
emulsion? Just slap some more on and it'll level itself out. I'd paint it
laid flat or at an angle rather than upright... And you're right that
emulsion is too thick. You'll need to thin it. You might get it though a
primer gun... Or just use a system designed for paint...



Lots of people used to have proper screens for their 35 mm slides - can't
you find somone to borrow one from?

I borrowed a projector from work once and was amazed how much better the
image was that in any of our conference rooms with white walls as screens.
The prism texture (or glass beads on some) give better viewing.



Yes, I do have one of those. That was my first option.
It's just not big enough. The projected image measures around 40" high x
53" wide. The screen I have is only 1240mm ( 49" ) wide.

For the cost of a sheet of MDF and a tin of paint, I thought I'd make
something better.
