This is the new "Green" formula from Aqua-Tite. This 1 gallon bottle will cover a 20' or so cover 2 times very well. They say it will cover between 500 and 700 square feet. This is to be used on Acrylic, cotton, nylon, polyester, polypropylene, and cotton/poly blends. This will come with a spray nozzle. However, for what ever reason the manufacturer chose this nozzle because it works well with the Aqua-Tite. They didn't take into account the nozzle WILL NOT fit on the gallon bottle. You will need to supply a smaller bottle to use the nozzle. We apply the product with a garden style sprayer.
