White Mountain Waterfall and Mortar Lacquer

We have used this lacquer based clear nontoxic sealer for over 10 years. We use it on finished waterfalls and border edge stone work to seal out the potential for concrete alkalai to affect the pH of the pond water.

We recommend 6-8 coats on waterfalls and 4-5 coats on border edge rock work. Quick drying abilities allow for two coats to be applied on one day. 1 gallon covers 75 - 200 sq. ft.

This product creates a long lasting clear glazed seal on rocks and mortar work and greatly aids in the maintenance process of your waterfall. Retards algae growth.

We sometimes substitute "Glaze-n Seal" for this product. Price is the same.

Herco (Hecht) Fish pond coating new formula instuctions - 4 Steps

Step1: Proper surface preparation is very important to a successful application. Pond surface must be fully cured (as in new concrete, gunite, shot crete) clean, (free of surface dwelling algae, in the case of renovations) dry and free from any oil or grease. Remove all debris by brushing, sanding, sweeping, and/or power washing. Acid washing may be required in some cases. We use straight Heinz vinegar.

Step 2 Apply one coat of Herco (do not thin) PSC Primer to entire surface of your pond using a combination of chip brushes and medium mat roller (as you would use for latex painting). Allow primer coat to dry a minimum of 3 to 4 hours.

Step 3 Apply 3 (important to apply 3 coats) consecutive coats of Herco coating. Drying time can vary depending on temperature, humidity and other environmental conditions. Allow a minimum of 3 to 4 hours between coats. Do not apply at temperatures below 50 degrees or if inclement weather is expected before coating is completely dry.

Step 4 Allow the final coat of Herco coating to cure at least 5 days. Rinse (purge) the entire pond surface thoughly with fresh water and drain completely before filling with water.
