PURCHASE EVERYTHING YOU NEED FOR THIS PROJECT
Ponds are prone to leaks, but proper pond sealing can prevent them. NeoPond Sealant helps maintain the integrity of your pond, and is both fish- and plant-safe.
Not Sure How Much to Order
Prep Your Pond
Get Your Supplies Ready
A successful project starts with preparation. Make sure you have all the supplies and products you need with our supply checklist.
Clean Your Space
All surfaces must be structurally sound, clean, dry and free from contaminants that would prevent proper adhesion. Concrete: Etched, power washed and allowed to fully dry. Wood: Mildew and organic growth must be removed using Deck and Patio Cleaner and power washed. Secure raised nail heads, deck screws and loose boards. Pre-fill imperfections such as screw holes, knots and splits in the wood with a high-quality wood filler.
Clean Your Space
Fiberglass: Sand the surface well with 120 grit sand paper to remove all gloss and roughen the surface. Clean well and wipe the surface with a rag dampened with acetone prior to application of Multi-Purpose Primer and NeoPond Sealant. EPDM Liners: Clean the area well and once dry, wipe the liner with a clean white rag dampened with acetone to remove migrating plasticizers and condition the surface to receive Seam Tape and EPDM Primer.
Cracks, joints, voids, etc. (1/8” or larger) should be pre-filled with a suitable patching material such as a high-quality wood filler, concrete patch material or suitable expansion joint caulking. Remove silicone caulking and replace with Liquid Rubber caulking (or equivalent).
Contain The Mess
Keep all materials on a flat/level surface, on top of a tarp or piece of cardboard. Have a pail of soap and water, rags and mineral spirits ready in case there is a spill. If a spill happens, use rags to soak it up, cleaning immediately with soap and water. If it is dried, use a razor/scraper to remove. Use mineral spirits to weaken the material and remove with a wire brush or grinder.
Note: Use mineral spirits sparingly.
Step-By-Step Project Walkthrough
Use 1 heavy coat of Liquid Rubber Multi-Purpose Primer or Liquid Rubber EPDM Primer.
Prepare Your Space and Gather Your Materials
Make sure your surface is clean, dry and sound and gather all materials needed. Concrete should be at least 28 days old and should be etched with a concrete etching product prior to application. Fiberglass should be sanded well with 120 grit sandpaper to remove all gloss and roughen the surface. Wood surfaces should have imperfections such as screw holes, knots and splits prefilled with a water-based wood filler or our caulking.
Bridge cracks, cold joints and transitions (floor to wall) using the 3-course method of Multi-Purpose Primer - 4” Geo-Textile - Multi-Purpose Primer. Apply a 6” wide coat of Multi-Purpose Primer along the areas and while still wet, embed the Geo-Textile fabric, fuzzy side down. Smooth out wrinkles and apply a second coat on top, taking care to fully saturate the Geo-textile. Allow to dry before application. For EPDM liners: Apply Seam Tape to any seams, tears or holes in the liner by peeling the backing film and pressing firmly to the repair area. Care should be taken to not allow wrinkles or bubbles in the Seam Tape. Once placed, press in the Seam Tape firmly with a laminate roller to ensure proper adhesion. Then apply EPDM Primer over the EPDM Liner (not the Seam Tape).
Tape-off, block off or otherwise mask areas that are not to receive coating.
Using a 3/8’’ (10mm) roller, apply Multi-Purpose Primer to the entire surface using a brush and roller at a coverage rate of approximately 175 to 200 ft²/gal. For EPDM liners: Use EPDM Primer. Allow the Primer to dry until it is tacky or dry to the touch, but do not leave it exposed for more than 6 hours before coating.
Using a 3/8’’ (10mm) roller, apply approximately 3-4 heavy coats NeoPond Sealant. Allow at least 4-6 hours drying time between coats. You can re-coat after the material is dry to the touch with nothing wet underneath and it is uniform in color. Apply each new coat at a different angle to the previous coat to ensure even coverage. For edges and corners apply using a nylon/polyester brush.
Inspect and Protect
Inspect for pinholes, blisters, thin spots or other defects. Recoat as necessary. Allow 3-5 days before filling your pond or using your fountain/water feature. When first filled wait 24 hours, wipe the sides, drain and re-fill to remove surfactants. Repeat if necessary. Do not add fish or plants until the coating is uniform in color and the water is clean. Be sure to test the water for proper PH levels acceptable for your type of fish and adjust as necessary
BE SURE TO TEST THE WATER FOR PROPER PH LEVELS ACCEPTABLE FOR YOUR TYPE OF FISH AND ADJUST AS NECESSARY.
Remove tape while coating is still wet and close container to secure leftover product. If spillage occurs, soak up as much material as possible with rags. Clean immediately with soap and water. If spill is dried, scrape off as much as possible with a razor or scraper. Use mineral spirits to weaken product and an appropriate tool such as a wire brush or grinder to mechanically remove. If splashed on the skin immediately wash thoroughly with fresh water. If the product has dried on the skin massage the area with medical grade mineral oil, baby oil or edible oil, then wash with soap and water. If irritation persists seek medical attention.
