Fish Pond Coating
New concrete leaches alkali, creating pH and water chemistry problems for fish. With Herco H55 you can instantly seal and leakproof new and old concrete, block and brick.
Offered in white, gray and black, H55 can be brushed, rolled or sprayed with an airless gun in two or more coats (one hour apart). One gallon covers approximately 100 square feet. After a 72-hour cure period, fill with water and stock with fish.
Herco thinner is required for clean up and/or product thinning. Primer is not necessary but HIGHLY RECOMMENDED—we cannot guarantee this product if it is not used with primer. Herco caulk crack filler is another excellent concrete product (white or clear) that comes in a 12 oz tube.
Made in USA. Ships Hazmat.
