These bags are basically a 1 : 2 : 4 concrete mix ratio. Knowing the weight of the materials and how much water to use Water can do the same thing to a glue or polyurethane compound, though their flexibility makes them a little more resistant to cracking. This adhesive comes in a small 4-ounce squeeze tube, a large 28-ounce cartridge, and a standard 10-ounce tube cartridge thats designed to fit most caulking guns.
