I have just built a setup with Great Stuff expanding foam, i had to do alot of cutting of it afterwards and it takes water in behind the foam. I have painted it with two layers of paint and now i need to find a good paint on sealant to make it water tight- even if it takes many coats. I havnt found anything tho, any suggestions? I search for pond sealant but im not finding anything in small quantities, as i would probably need less than a gallon.
