there should be amix ratio on the can, but lots of them are not giving much info. try and get the paint mix to be about as thick as a heavy chocolate milk, like described above, mix it thick and try a bit of spray, if it comes out stringy or leave the surface very wavy (orange peel effect) then thinn it a bit more. and try again...
Just don't take a drink to see if it is the right consistancy!
