    A beautiful pond can be the centerpiece of your home. It adds a level of elegance, adventure, and intrigue that can’t be gained from any other property feature.

Just applied

Traveled way farther than expected even with heavy coats. Building a concrete koi pond and I rolled it super heavy twice and then did two heavy stay coats. I may have enough to put one more final as well.

Rita Chambers
Easy to apply

I had a seam failure in EDPM liner and had limited success with other products I now have Koi back in pond and am happy to say water level is holding! Only time will tell, I only wish I would have used this product line on first installment, when liner was free of pond crust.

Applied 6 coats and waiting 72 house before putting water in the pond

Joseph Peters
Great product works great

I have a fountain in my backyard that has given me off and on problems for years. I've tried numerous products in attempting to seal from leaks with little luck. I did 4 coats of Liquid Rubber and the fountain remaining full, no leaking. I'm beyond happy with this product.
