Pond Armor Black Pond Shield Non-Toxic Epoxy – 1.5 Quart Kit

Pond Armor Black Pond Shield (SKU: BLACK-QT-R) is a non-toxic, two-part epoxy pond liner designed for professional and DIY installation on concrete, masonry, metal, fiberglass, wood, stone, and most plastics. Once cured, it is completely fish, plant, and wildlife safe — approved for koi ponds, freshwater aquariums, saltwater tanks, swimming pools, fountains, hydroponics, and waterfalls. Made in the USA. The 1.5-quart kit covers approximately 60 square feet at 10 mils thickness on a smooth surface (rough/porous surfaces require more material or a second coat). The self-priming formula requires no separate primer for most applications — just clean, etch, mix 2:1 (Part A:Part B), and apply. The coating can be put into service in as little as 24 hours. Tested from -78°F to 140°F, it resists cracking, peeling, and blistering in freeze/thaw environments. BLACK-QT-R 1.5 Quart Kit ~60 sq ft @ 10 mils 2:1 Mix Ratio 24 Hr Service -78°F to 140°F Self-Priming Fresh + Salt + Pool Made in USA ⚠ Mix Ratio — Critical: Always combine 2 parts Part A to 1 part Part B. The kit is pre-measured — use both containers entirely. Incorrect mixing ratios result in incomplete curing. Thoroughly scrape the sides and bottom of the mixing container during mixing. Key Features & Benefits 🐟 Non-Toxic — Fish & Plant Safe Once fully cured, Pond Shield is completely non-toxic to fish, plants, invertebrates, and wildlife. Safe for koi ponds, goldfish ponds, freshwater aquariums, saltwater reef tanks, and hydroponics systems. In service in as little as 24 hours — no extended waiting periods required before introducing aquatic life. 💪 Stronger Than Concrete Pond Shield has a tensile bond strength that exceeds the internal strength of concrete — meaning the coating won’t delaminate before the concrete itself would fail. When hairline cracks form in mortar or grout joints over time, the flexible Pond Shield coating bridges the gap and resists mimic cracking, maintaining waterproofing integrity. 🏊 Fresh, Salt, Pool & Chlorinated Pond Shield is chemical-resistant and approved for use in saltwater tanks, chlorinated pool environments, aquariums, hydroponics, and freshwater ponds. One formula, unlimited applications — from a Japanese koi pond to a formal reflecting pool to a commercial aquarium display. 🎨 No Primer Required Self-priming formula bonds directly to properly etched and cleaned concrete, metal, fiberglass, wood, stone, brick, most rigid plastics, and previously applied epoxy coatings. No need to purchase and apply a separate primer coat for most surfaces — reducing project steps and cost. 🌡️ -78°F to 140°F Temperature Range Tested across an extreme thermal range from deep freeze to summer heat. Suitable for outdoor installations in all climates, including Northern freeze/thaw environments where concrete movement and temperature cycling would crack less flexible coatings. Apply during cooler parts of the day (early morning or late afternoon) for best pot life. 🔧 Easy DIY Application Applied with a brush or roller in most applications. For most smooth surfaces, a single coat at 10 mils is sufficient. Rough or porous concrete may require two coats — apply the second coat within 1.5 hours of the first for best inter-coat adhesion. Mix thinly with 90%+ isopropyl alcohol if needed to improve flow on vertical surfaces.

Rough or porous concrete will reduce coverage and may require two coats. Always calculate based on surface porosity, not just square footage. Application Overview Etch and clean surface with Pond Armor Surface Prep — concrete must feel like 60-grit sandpaper after etching. Rinse thoroughly and allow to dry completely before epoxy application. Mix Part A and Part B at a ratio of 2:1 (Part A:Part B). Thoroughly scrape sides and bottom of mixing container. Incomplete mixing = incomplete cure. Apply evenly with roller or brush at 10-mil minimum thickness. Apply during cooler times of day for best working time. Second coat (if needed): For rough concrete, apply second coat within 1.5 hours of the first. If more than 10 hours have elapsed, lightly sand with 60-grit sandpaper before applying the second coat. Cure: Tack-free in ~1.5 hours; ready for water in minimum 24 hours (36+ hours in cold conditions). Always follow Pond Armor’s official instructions. Wear gloves and eye protection during mixing and application. Frequently Asked Questions What is the coverage for the Black Pond Shield 1.5 Quart Kit? The 1.5 quart kit covers approximately 60 square feet at the minimum required thickness of 10 mils (10 thousandths of an inch — about the thickness of three sheets of paper) on a smooth surface. Rough or porous concrete reduces coverage because the peaks and valleys in the substrate consume more material than a flat smooth surface. For rough concrete, plan for the lower end of coverage or purchase an additional kit and plan for a two-coat application. To size up: 1.5 gallon covers ~240 sq ft smooth; 3 gallon covers ~480 sq ft smooth. Why is a non-toxic epoxy better than a rubber pond liner? Pond Shield creates a seamless, structural bond to the pond surface — no liner folds, no creases, no risk of puncture from heron claws, sharp rocks, or root growth. Unlike rubber liners, it bonds directly to the concrete or masonry structure: No loose material: Herons can’t get their talons under it; ground movement doesn’t shift it Seamless application: No seams to degrade or leak over time Chemical resistance: Works in saltwater, chlorinated pools, and aquariums — not possible with most rubber liners Temperature flexibility: Tested from -78°F to 140°F without cracking Is surface preparation required for Black Pond Shield? Yes — surface prep is the most critical step for a successful Pond Shield installation. For concrete: use Pond Armor Surface Prep etching solution to remove calcium laitance, open surface pores, and achieve a 60-grit sandpaper texture. Rinse thoroughly, allow to dry completely. For metals: remove corrosion and abrade the surface to create tooth. For fiberglass: sand with 60-grit. For wood: ensure rigid — no flex. Pond Shield’s self-priming formula handles most surfaces without a separate primer after proper prep. Can this epoxy be used to repair existing pond leaks? Yes — Pond Shield is excellent for waterproofing cracked or leaking concrete ponds. With tensile bond strength exceeding the internal strength of concrete, it bridges hairline cracks and resists mimic cracking as the concrete expands and contracts. For larger cracks (3/16”+) or wall-to-floor joints, Pond Armor recommends reinforcing with fiberglass mat or woven fiberglass before coating. Fill larger gaps with Crack RX before applying Pond Shield. How long should I wait before adding fish? Pond Shield is tack-free in approximately 1.5 hours at 70°F and ready to fill with water in a minimum of 24 hours after the final coat (36+ hours in colder conditions below 60°F). Once filled, a quick water change or rinse helps remove any surface dust before introducing fish. No extended waiting period is required — the 24-hour mark is sufficient for fish introduction under normal conditions. Cold weather significantly slows cure; in temperatures below 50°F, extend the cure period accordingly. Does the black color fade or chalk over time? No. Pond Shield’s black color is UV-stable and specifically engineered for submerged outdoor environments. The deep black finish resists chalking and fading, maintaining its appearance in both above-water and submerged sections. The black color provides a natural, depth-enhancing backdrop that makes fish colors more vivid and gives the pond a clean, formal appearance. Algae can be easily wiped off the cured surface without scrubbing or chemical treatment. Why Buy from Pond Pro Direct?
