For rendered ponds, there is one brand of pond sealant that people look to for excellence – Bondaglass is made from fibreglass composite, and sets hard and sealed onto natural rock or concrete to keep your pond water exactly where it is needed.
Normal concrete or natural rock is not usually water-tight enough for you to stop losing water through the bottom of your pond and into the water table. This means that you may spend forever refilling your pond with dechlorinated water to ensure it has healthy levels.
Using this Bondaglass pond paint means your pond is secure. About 3 coats should do the trick, available in clear, green or black to help with your pond aesthetics around the edge or in shallow areas where the bottom may be visible.
To be used either as an alternative to pond liner or in conjunction with it for a super-secure pond, just buy the quantity you need for a few coats and get to work, waiting until each coat is always dry (just a little sticky) before applying the next, ensuring a perfect seal.
