White glue or matte medium for securing ballast?

[nachoman]

I use white Elmers glue & tap water mixed about approximately 50/50, or sometimes a little more dilute. I put a teeny drop of dishwashing detergent into the mixture to help it flow better. For wetting, I've used both alcohol and soapy water. I prefer a small spray bottle that puts out a fine mist (those finger action hair spray bottles work great) and fill it with tap water and a few drops of dishwashing detergent. I've used rubbing alcohol, too, with good success. But, the detergent works fine and is cheaper and smells better.
