hello out there,

i have been trying out different types of acrylic flat dullcotes, and for some reason when ever i use the gunzo/mr colour flat dullcote, it dries cloudy and almost dusty, has anyone else had this problem, i have tried 3 different bottles and had the same result, i am mixing at about 50/50 with plain tap water, and spraying at around 10 psi, is my mixing correct ?

any help would be appreciated
