This may not be the definitive answer, but are you using a one gallon size sprayer? If so, that could be part of the problem-you may need a smaller sprayer that produces a finer mist.You can normally find these spray bottles in the ladies hair care product aisle at the local Rite-Aid. Also, when you add the water to the mix, make sure you use at warm to hot water as this helps to blend the two together.Make sure you shake it vigorously until FULLY mixed. Coldish water will make it congeal somewhat making an unsprayable "gloopy" mess. Along with that add a FEW {not too much} drops of dish detergent to help reduce the surface tension and promote mixing. I always have a seperate spray bottle of 70% rubbing alchohol that I mix with water 50/50% that I use in conjunction with glue/water/detergent mixture as that helps break down the surface tension even more. Like I said, this works for me, others may have other recipes. Any questions send me a line.
