I have tried approximately 5 different types of screen paint. Some from the USA, Britain and Europe. One of these(Goo) cost over £200 and nothing has come close to this paint. Contrast is great, detail likewise but the colours are quite simply astonishing. HD content is addictive to the point that I don't want to turn the projector off. Even my very sceptical wife is a complete convert to this type of viewing experience. In short, save yourself a lot of money and buy this stuff. I guess I've done the money wasting for you.
Just as a side issue. I'm using a Xiaomi UST 5000 lumens projector which is amazing. It even has a great sound system built in..
Firstly & most importantly - the picture is so much better than my white screen - colours deeper and so much more colourful - I'm very happy with this paint #3 Dark Abyss. Great value and recommend it. Have a UST projector.
However it isn't that easy to apply perfectly with a paint roller. I didn't have a spray gun which would have been best...used a roller with the smallest nap hair length I could find. It rolled on absolutely fine but it dries quite quickly and where you get overlaps in the same place after 4 coats or so you can sort of see it a little - not enough to really bother me but you should try and use a spray gun if possible. Don't even think about using a brush.
I have a 100" screen and I'm quite handy at painting.
