Possibly, but that's not how it's intended to be used. I think Pond Armor sells a polyurea coating that can be sprayed. Pond Shield is designed to be thick so that a single coating is sufficient to get to a 10mil thickness and complete water barrier. If you thin it too much you risk compromising its sealing ability.
