video Put UV tatoo on your wall
I got UV paint additive from a friend. Sorry that I can't tell you where to get it or a brand or anythink, because I don't know (maybe someone in discusion can add that?). I just mix it 1:20 with basic white color, select pattern I wanted to use. Printed it in 1:10 scale (1mm on the print = 1cm on the wall) and transfer it to the wall using masking tape (2x50m). Dimension of the wall are 3,6m x 2,6m, UV light is 25W Omnilux UV light bulb.
