What is the HERCO Pond Coating System?
The HERCO Pond Coating System is a line of products manufactured by Hecht Rubber Corporation specifically designed to coat, seal and leak-proof your pond, eliminating many of the problems associated with pond construction and upkeep.
The system consists of four components: HERCO TC700 Cleaner, HERCO CCF Crack Filler, HERCO PSC Primer and HERCO H55 Coating. The products are custom formulated for ponds and are 100% fish-safe and environmentally friendly. HERCO Coatings create a durable and long-lasting membrane, sealing off pores in new construction ponds as well as leaks and cracks which may develop in ponds over time.
The elastomeric nature of the membrane allows for shifting of the concrete underneath, such as may result from seasonal expansion and contraction. HERCO Pond Coating acts as an impenetrable barrier, preventing the buildup of alkaline salts and other contaminants that typically leach out of concrete and into your pond water.

How much product will I need to cover my pond?
The amount of product required depends on the size of your pond. A quick way to estimate the square footage of a typical pond is to take your length, width and average depth and multiply the three. For example, if your pond is 10ft by 10ft and 2 feet deep, 10x10x2 =200. One gallon of HERCO Coating will cover about 80 to 100 square feet with the recommended 3 coats, so you will need two gallons of coating in this example. It is always a good idea to allow a little extra, especially if you have overhangs, rocks, waterfalls, etc.
Can I apply HERCO Coating over old paint or coatings?
Yes, but only if the old product is adhering well to the surface below. If you have paint of old coatings that are flaking off, you must completely remove the old product using mechanical means such as wire brushing, sandblasting, scraping, pressure washing (minimum 3000 psi). After removing the old coating and all dust and debris, we recommend a final cleaning with HERCO TC-700 cleaner prior to applying your new coating.
What surfaces can I cover with HERCO Coating?
HERCO Coatings bond tenaciously to just about any surface used in pond construction! Concrete, brick, rock, block, gunite, marcite, wood, steel, aluminum, even plastics and glass can be coated. The surface must be solid, dry and free of debris and you cannot apply the coating directly to dirt or gravel.
Do I need to use the HERCO PSC Primer before applying the coating?
The HERCO PSC Primer absorbs deep into the microscopic pores of the surface you are coating and is the “first line” of defense against leaks. The PSC primer helps with adhesion of the HERCO H-55 Coating and is an integral part of the coating system. Primer is not required if you are coating directly over a rubber pond liner (see below).
How long will it take to coat my pond?
This depends on the size of your pond. The average garden Koi pond takes 1 or 2 days. Be sure to follow all instructions and allow a minimum of 3 to 4 hours between coats.
Can I apply HERCO Coating on top of my old pond liner?
Yes! HERCO H-55 adheres well to rubber, even your leaky old pond liner! Just be sure to clean the surface thoroughly before you apply the coating. You will not need to use the PSC Primer when applying coating directly over a rubber liner.
How long does concrete have to cure before applying HERCO Coating?
Concrete surfaces must be fully cured, clean and dry before applying coatings. Generally speaking, concrete needs about 30 days at 75F to cure and dry out before applying any coating or sealer, though it may take significantly longer in rainy or cold weather. The product will not adhere well or cure properly if applied to wet concrete.
Is the HERCO product safe for my fish?
Yes. The HERCO Coating System is specially formulated for pond use. When properly applied and cured, the membrane is completely inert and 100% safe for your fish and aquatic plants. The formulation is also environmentally friendly and meets or exceeds the most stringent regulatory requirements.
Under what weather conditions should I apply the product?
Ideally, the coatings should be applied under temperate conditions. HERCO Coatings are air-cured and should not be applied at temperatures under 45F or in rainy weather, as this will prevent proper curing of the product. If the temperature is above 90F, it is best to coat in the early morning or evening and out of the direct sun.
What happens if it starts raining in the middle of the job?
While it is best to start the job when the forecast is for clear weather, in the event that rain falls on the uncured coating, simply allow extra time for the coating to dry completely before continuing with the job or applying any additional coats. The coating needs to be dry to the touch before you apply an additional coat.
