Sounds like you need to find a better spray bottle......I use a cheap $1 bottle from the Walmart pharmacy, but it has a screw adjustable nozzle, so you can adjust it down to nothing, and then slowly open it till you get a fine mist of water. The bottles come in several colors, so I use blue for water, orange for glue mix and green for alchohol (but I seldom use alchohol). Sprinkling a coat of cover on the wet paint isn't a bad idea, but I generally don't do it. I use many layers and colors when I put down my ground cover.....nature seldom does large areas of one color, so neither do I. When I get the look I want (that's why I don't use any glue prior), I use the finest mist of water (or alchohol) I can get, and REALLY soak the foam.....seeing standing water is not bad and the foam soaks it up.....you just don't want the have the foam float around. At this point, the foam shouldn't move when you apply the glue mix...again using the finest spray you can get. But again, the key is finding the right bottle. If your bottle sprays fine enough it's 90% of the battle.
