Wall paint instead of a projector screen - which colour?
Jim Kelly
the merits of painting the whole wall suitably for projector use.
Anyone experimented with the paints that are readily available in
Australia??
Money saved on a screen could be spent on a brighter projector
with a better contrast ratio to compensate for the painted wall
not being optimal . . .
Thanks for your thoughts, experience.

Ceiling white or screen paint. Screen paint costs a bomb for what it is.

I checked with Dulux and they don't have a firm recommendation .
. .
Does ceiling white work ok?

Google for screen paint. I think it is from the US. Bloody pricy.
Ceiling white is meant to work ok if you have a flat wall. I made a cheap
wooden frame and stapled curtain sun blockout material to it. Works well
and costs bugger all.

everyday. They are new, seem to sell for $200-300 and are motorised. So you
mount them on the ceiling and when not in use retract up . I've considered a
feature wall with screen paint, but it seems expensive and depends on what
you read can be tricky to apply and require a special undercoat as well.
I've also seen a tripod stand from officeworks for about $300.... Pretty
decent size and you can more it around.

more I am going to be happiest with a painted wall. If 'ceiling
white' is known to work OK then we already have a viable
solution.
We have seen a system setup just like this with a mid cost three
year old projector. The owners had bought an expensive screen at
the time (still have it stored away!) and decided that the small
improvement over their flat wall does not warrant having the
thing look ugly when not in use. The wall (just happened to be)
an off white, almost cream colour.
Our wall is flat plasterboard so we just need to discern what
paint(s) do a good job and choose one! The ceiling has exposed
feature beams so even a retracting electric one would look ugly.
Google shows up a few hits via 'screen paint':
Paints include a silver (not sure that we could handle that for a
whole wall?), white and 'Misty Evening Gray'

Goo Systems IS expensive . . . au$330 for 4.65 sq m.!! I'd need
two of these! Four for two coats!!

Another USA option with interesting discussion on contrast':
https://www.diytheatre.com/diy_projection_screens/projection_screen_selection.htm
It looks to me as though a high contrast paint is grey/gray, and
low contrast is white (ceiling white?).
High contrast (grey) paint recommended for use in ambient light,
or with lower cost projectors with low contrast ratios
". . . you will likely find that in bright scenes, the grey
screen looks dull and less engaging".
White is used in blacked-out rooms, and with projectors with high
contrast levels,
". . . in dark scenes, the black level of the white screen is
distracting and unacceptable".
(quotes by Brandon B).
Not really much help since I expect to get a high contrast
projector, and would like to have some use in subdued ambient
light . . .

SO, maybe the Aussie answer could be ceiling white with a little
grey tint added????
Pity Dulux hasn't made a mix for the job. Haven't tried the other
Aus brands . . .

Standard quality ultra flat high opacity ceiling paint works very well.
When you buy your paint get the person in the paint shop to add the tiniest
drop of black to the paint and mix it well on the machine. The addition of
the black does not affect the colour, but slows the yellowing process down
significantly as the surface is exposed to UV and oxidises over time.
Just bear in mind that ceiling paint doesn't wash well like normal quality
vinyl or acrylic based wall paints do. So if the wall is in an area where
it is likely to get marks on it, you may be repainting it frequently. But
then again, ceiling paint isn't expensive. :-)

tins - then report back to us which you found to be best ..... personally,
if I was to go that way, I would probably try some firm of metallic silver
as well as a few white/light greys...... after all it is called the silver
screen

Good idea . . . but!! . . .
We are just renovating the room at present - haven't even decided
on a projector yet, let alone got one. Complicated too by wanting
to paint the whole wall in the agreed colour. Will do some
reading here before asking advice on a projector too. A quick
look makes the decision pretty scary, and then there are the new
formats to consider (or not). I wonder if Melbourne has some good
demo areas to peruse??

with a couple, having been in the industry in a previous life. - Just
contact me off group and I would be pleased to discuss further. Regarding
the paint-it-and-see suggestion: I was really referring to say, 1 metre X
650mm areas that would give the effect you need and enable good comparison.
Personally, I reckon just about any white/near-white surface will be
acceptable. I believe matt or near-matt is the way to go. I recall
discussions years ago about screen-goo and the overwhelming consensus was
that ceiling white was not quite as good when seen side by side to it.......
like, when is that ever gonna happen in a home anyway!!!!

mounted between the curtains and the pelmet box - required extending the
pelmet a couple of inches further out from the wall.
Works a treat. When the screen is up, it is completely out of sight.
Close curtains and press the magic button and, kazaam, 120" 16x9 screen
drops down. Installed it myself in about 2 hours.

Hi Jim,
I have experimented with a combination of the following paints, all
found at Bunnings
Using a matt roller, not foam.
Step 1: Three coats of the following mix of : 10% Dulux ceiling paint,
brilliant white code number 615??1949 (paint dripped over code), 40%
Dulux Metallic Effects 69084895 and 50% Dulux clear coat Matt clear
69084893.
This went straight onto a white wall, the screen size being approx 4
metres x 2metres.
I am using a Panasonic ceiling mounted pj that is approx 5 metres away
from the screen.
I will take some photos and post
regards
Murf
