If I needed a screen, I would first consider those from Silver Ticket on Amazon. The price is really solid on a well reviewed, well tested, and solid screen.
If you need ALR, forget about paints. They really don't (and can't) work. You can have dark screens with reflective materials in them, but those are basically positive gain grey screens, they aren't actually ALR. ALR screens reject light from certain angles and require a longer throw lens to work properly unless they are built for ultra-short throw (UST) projectors. ALR screens have several layers applied, including a special optical layer which works to eliminate light from the sides. Some reject light from the top/bottom as well.
These screens cost a lot of money because they are tough to manufacturer.
They also look like crap.
Amazing, but crap.
That is, you don't get something for nothing. In this case, the standard ALR screen always adds hotspotting, image uniformity issues, and sparkling to the image. These are severe and easily visible issues with an image compared to a standard white screen. What they give you in return is a more viewable image in a brighter room and much better contrast in a bright room.
In a dark room, ALR screens add nothing to image quality and just detract from it.
I consider ALR screens the ultimate Sports Bar screen. They can work really well in some boardrooms as well. They just aren't ideal for home use, but they work if you accept the drawbacks.
Since you need some specialized optical coatings, all you get with a so called ALR paint is added gain in a darker paint material. The darker paint sucks up some ambient light to help with black levels, but it has no real way to reject incoming light. It lacks that optical property. Still, in a lit room, it may be better than a white screen which will be quite washed out.
Oh, and UST/ALR screens use a sawblade optical coating that can't be replicated by ANY paint on the market. The grooves are a physical part of the surface and while UST/ALR screens are better than long throw ALR screens, they still have issues. There are ZERO paints that will come close to replicating a UST/ALR screen. Period.
Once again, in a dark room, UST/ALR screens are not necessary.
