Floating homebuilt screen

Hey guys, long time lurker here from Oz

just a little log of my progress on my screen ive been building. long term goal is to get the ambilight going behind my screen with a rpi or similar.

hence why there's two frames, one for the screen and the other to support the LED strip i intend to use.

used angle brackets to hold the screen, and hdd magnets to steady the lower section

more pics to follow, trying to decide between black or grey screen now!

Nice work here - looking good so far.

I see you found James of AZ's Grey Pearl mix; you should also consider Ftoast's mix options here: https://www.avsforum.com/forum/110-di...een-paint.html. I think you might have some ease of getting these paints in Australia - as long as you can get the Ralph Lauren metallic paint (off the shelf) you can use virtually any interior flat latex tinted to the color of your choice for mixing with the metallic, and you can go as dark as you'd like. These would work if you want to roll the paint on. You can also search this forum section for MaxxMudd for another rollable paint solution although I'm not sure how easy it will be to get the paints needed for that one in your locale.

If you want to consider spraying the paint on your screen, there are other paint choices as well if you peruse through this section of the forum. You can search for SilverFire, BlackFlame, and BlackWidow for lots of discussion on these mixes.

If you provide your room dimensions, projector model, and lighting conditions you'll probably get some more specific suggestions tailored to your situation. What color are you painting the rest of the room? Common thought is that the darker the surrounding walls and ceiling, the better for front projected images, and that will make at least as much difference to your image as will the screen color. Also, do you plan to watch any 3D material? If so, that will have an impact on how dark you can go.

Looking forward to seeing your build progress!

Just wanted to blurt in here that (barring international shipping and included charges) I think you'll find BlackWidow OR JamesofAZ's GreyPearl mix to be the easiest to source locally. James has managed to help many folks from all over the world find local paints to use for his mix, which can make it a great option for those outside of the USA.
Likewise, the AAA-fine metallic used in BlackWidow is available online in just about every region around the world, and there are satisfied Australian users of BlackWidow both here on AVSforum as well as the HomeTheaterShack forum.

Both of these mixes can be rolled or sprayed, whichever is your preference.

I see that you already mentioned your interest in James' thread, so you've already made the best first step toward getting his attention and help finding local paints for the GreyPearl mix (or BlackPearl mix if you end up leaning that direction). If he's busy it might take a few days to hear back, but I don't think he's left anyone hanging.

A couple questions about your frame:
What is the screen-size (it looks like about 120", but that's just a guess from the height and the doorway)?
Can you add some narrow trim (1/4" will do the job fine) along the outer edge of the front?..this will make sure the material you stretch over the frame doesnt touch the supports or inner sections which can leave weird little shadows/dark-lines on your screen if they touch.

That projector has a great amount of real-world brightness even in its dimmest settings. Do you already have your eyes on the model you hope to replace it with at some point, or are you still shopping around?

I know the earliest versions of JamesAZ's BlackPearl weren't particularly friendly toward 3D (at least when used at large sizes), so keep that in mind if you're a 3D fan and deciding between the GreyPearl and the BlackPearl.
I've also heard James has been continuing to work on his mixes, so he might even have something between those two extremes (something bright enough for 3D not to have trouble, and dark-colored enough to give that extra-dark appearance you're looking for).
Of course (as long as I'm not too far off on guessing your screen-size) with your bright projector you won't be in bad shape either way, and if you aren't a big 3D user you shouldn't have much of anything to worry about.

screen size is 3.2m (126") slightly too big for the room, but we never complain about that right?

room is 5.2m long by 4m wide (17ft x 13ft)

my plan was is to paint as i tested with lycra/ blackout curtain/ spandex/ fine sheet and found the painted wall i had at the time of testing to be the best for image quality. so the next step is to find a colour that suits, i have had previously a creme/white wall which of course washed out the colours. I've been suggested to try grey and found that to have really good blacks; as shown in picture.

the projector id like to upgrade it to is:

Im not too worried about 3D, its always been a gimmick to me. Even in the cinemas it doesn't feel right, the only proper 3d id consider is the HTC vive - need to build a room for that too!
