Repairing a liner is possible in most cases with a liquid EPDM material. EPDM is a kind of synthetic rubber. Herco Fish Pond Coating material is a neoprene-based product for covering cement block, brick and cracked concrete ponds. Pond Pro 2000 is your answer. It is a 100% liquid EPDM and 100% compatible to your EPDM liner sold in pond supply stores. It works extremely well on all non-porous concrete fountains as well as EPDM fishponds liners. Reflecting pools are another good application for The first and most important step of proper pond management is choosing your primary objective for your pond and understanding the management requirements. So, whether you have a pond or are planning to construct a pond and lining it with a pond liner and protective underlay, installing a prefabricated pond or a natural pond with no man-made intervention, it will require a level of ongoing maintenance.
Repairing a liner is possible in most cases with a liquid EPDM material. EPDM is a kind of synthetic rubber. It is liquid until a catalyst is added that causes it to harden.

The synthetic rubber liners are considered the most durable. They are water and heat resistant. It is resistant to the fading caused by UV light. It rarely tears, because of its high tensile strength. But, a torn liner is the most common cause of a pond leak.
Concrete ponds are difficult to repair, especially in winter where the cold climate causes the ground to heave. Masonry-based repair materials dry rigidly and will break again during winter. Herco Fish Pond Coating material is a neoprene-based product for covering cement block, brick and cracked concrete ponds. This material becomes a heavy-duty neoprene membrane that gives a long-lasting repair.
Good Pond Liners have some things in common that prevent frequent damage. Flexible materials are popular. They are manufactured in sheet form with factory-welded seams, and U.V. stabilized to resist the effect of the sun. Mostly they are black in color for reflecting value, and are fish- or potable-grade. They will last longer if buried and away from sunlight (around 20-30 years more than rubber materials).
Pond Pro 2000 is your answer. It is a 100% liquid EPDM and 100% compatible to your EPDM liner sold in pond supply stores. It works extremely well on all non-porous concrete fountains as well as EPDM fishponds liners. Reflecting pools are another good application for EPDM. These are demanding applications where the unique properties of EPDM have a distinct advantage over other products.
Pond Pro is a liquid version of EPDM very similar to EPDM pond liners sold in pond supply stores. It works extremely well on all non-porous concrete fountains as well as EPDM fishponds liners. Reflecting pools are another good application for EPDM. These are demanding applications where the unique properties of EPDM have a distinct advantage over other products. The success of PondPro 2000 is through combining ethylene and propylene with a diene monomer. PondPro 2000 is safe for fish and plant life as well as chlorinated water. This polymer (when crosslinked) is an excellent moisture barrier, resistant to oxidation and UV degradation but its most important property is its ability to tolerate both low as well as high temperatures (from minus 62 to plus 350 degrees Fahrenheit).
General EPDM rubber is used exclusively for radiator hoses, freezer gaskets and low temperature seals, steam hoses, and rubber roofing membranes. It is also blended with other rubbers to improve their properties. A multitude of products are now better and last longer because of the contribution made by EPDM rubber.
