Question Screen paint choice...Crumbs!!!

Hi there
Im hoping MississippiMan is about as this questions been asked before but it seems the answer is set up specific so i'm now very confused and hope its ok to ask for advice.
I'm in Scotland and have a Optoma UHD300x. The pj is in an all white room and looking to project onto wall screen with a diagonal of 100". I presently have a white 92" grandview but looking to get a larger ALR grey type screen but don't think i can afford it so now looking at diy painted screen.
I welcome any advice with thanks ☺

I'm glad you decided to come aboard and ask your questions. Never hesitate...that is exactly what this Forum is all about.


Your choices to create a Grey ALR screen will be determined by the availability (Local or Web-based) of certain components that ramp up the ALR performance factor to a level where your getting results decidedly superior to just a simple Grey Paint.


One thing you have on your side is your limiting your screen to 100" diagonal. That optimizes the 2200 Lumen output of the Projector.


Chief components you need to source are a fine flake White Pearlesecent and a clear Matte Polyurethane, both Water Based. The latter is often references in the UK as being a Clear Matte Water Based "Floor Finish" so looking under that designation can be fruitful. Finding a proper Silver Metallic will be a bit more problematical....but can be done. The proper White Paint (Dulux Ultimate White?) should be readily available to you however....and by tinting that White to a specified Grey, you can avoid the need to obtain the 4 separate Colorant Tints that make up the ultra dark Neutral Grey Colorant such advanced DIY Screen Paints usually require. It won't "quite" be the same, but will suffice in a pinch...and because your screen size is helping, and limitations in performance will be minimized.


The last choice would be to order a specific Screen paint designed to provide ALR performance, pre-mixed and ready to apply. All told the cost of the latter would still be far under the purchase price of even reasonably affordable, "truly proficient" Mfg ALR Screens.


Finally, be advised that to apply any high contrast Grey paint that has any really appreciable amount of true ALR properties, you need to spray on the paint. Rolling sets up sheen characteristics as well as potential issues such as visible Roller Marks.


There it is, your full course repast. Hope it all goes down easily. You might try a wee bit of some 100 yr old Scotch. Always works for me.

Give m time to review those alternative components and compile a suitable Mix.


Again...can you spray your screen? It's so small (sorry) that it should be extremely quick and easy.

I'll have to do some checking to find the correct Color Code of a Neutral Grey for the UK

Thank you so much for your effort
So when i have the colour code - do i just buy a grey tint and mix it all up and apply?
Thing is it was my better halfs idea to paint on the wall as shes fallen out with the screen casing...Of course my initial idea was to paint the wall...funny that!!! ;D
Ah - found the Like buttons thanks..and a spray gun https://www.amazon.co.uk/VonHaus-800...58985561&psc=1

Just wondering - I have a 92" white Tab tensioned screen and the picture (obviously in darkened room) aint half bad...I've just spotted another Grandview except NOT TT and 106"...Are these all made from same material - Mines is the Large Flat Series?

The Paint Store you purchase the Paint fromwill tint and mix it up.


You will have to mix everything else together along with it in a separate container, strain it, and the squirt. We'll go over the technique later.



I have successfully painted onto Matte White TT screens with fantastic results:
