I thin the latex about 20% or so. Some colors need to be thinned more than others. I spray it on in light coats. The first coat only leaves a light coloring. I keep spraying light coats until everything is covered. On cool days, I use a hair dyer between coats get to help kick off the surface drying. The trick to latex is patience. It takes a couple of days to a week before it fully dries. I usually wait a week or so before I mask it off for a different color. I also wait about two weeks or so after all colors have been painted, then I take steel wool to it to start the weathering process.
