Liquid RubberNeoPond Waterproof Pond Sealant - Fish and Plant Safe Waterproofing Membrane Sealer for Ponds and Water Features, Black, 5 Gallon

This product is very easy to apply. I brushed it onto a cement pond that was leaking and crumbling. Brushed it clean first then brushed it on. Was dry enough for recoat by the time the first coat was completed. The pond held water soon after.

Paint manufacturers have decided that water based latex acrylic paint is good enough. It is not. This paint washes off in the rain. It peels up on the bottom of the pool. It is a terrible product.All latex paints (not to be confused with actual liquid rubber) are garbage.The entire paint industry is currently a gigantic scam. Bring back proper oil and urethane paints please.You should all be ashamed of yourselves.

Highly recommend to go through the Tips on the product description to ensure the sealant will bond strong and prevent creak/leak. I cleaned the pond first, make sure the surface was completely dried, then applied the sealant evenly. I left it dry for 36 (more than 24 as recommended tips), and checked or any cracks/leaks before applied another coat. It works great, but just on an expensive side.

This coated my pond liner and saved me hundredths of dollars . Instead of replacing the liner I used this and it works and is not difficult to apply. I had a question and called the company and the customer service person explained everything in detail and told me to call back if the solution didn't work. It worked. Great company to deal with.

I have an old fiberglass fish pond, 16' x 10' x 2.5'. It had many problems holding water so I used spray foam for the while thing and once cured, painted the whole surface with two coats or more. Pond no longer leaks.
