PondPro2000: Liquid EPDM for Pond Repair, Waterproofing, and Protection

PondPro2000 is a two-component liquid EPDM (ethylene-propylene-diene monomer) rubber coating that cures to a seamless, flexible membrane. It solves leaks in concrete, EPDM liner, metal, and wood structures—permanently.

Why Liquid EPDM?

• Temperature range: –62°F to +350°F (survives freeze-thaw, thermal cycling)
• Fish/plant safe: Certified non-toxic, chlorine compatible
• UV/oxidation resistant: No chalking, cracking, degradation
• Self-leveling: 20 mil target thickness, seamless
• Adhesion: Concrete, EPDM, PVC, metal, wood, masonry
• Chemical resistance: Broad spectrum—acids, alkalis, salts, organics

Primary Applications

• Concrete ponds/fountains/reflecting pools: Bridges cracks, prevents spalling
• EPDM liner repair: Seamless overlay on aged/seamed liners
• AC drip pans: Rust stop, moisture barrier
• Corrosive environments: Poultry/hog barns, plating shops, paper mills, smelters
• Spill containment: Secondary berms, chemical storage
• Concrete tanks: Cold-climate spalling prevention
• Structural steel: Humid/corrosive interiors

Surface Preparation (Critical)

• Clean, dry, structurally sound
• Remove: oil, wax, loose coatings, brittle caulk, chalk (detergent scrub + rinse)
• Rust: wire brush loose oxide. Tight rust = coat directly
• Asphalt aluminum: remove max possible
• Roof cement: replace with butyl caulk
• Torn rubber: adhesive butyl tape + patch
• Smooth metal/plastic: abrade for adhesion
• Deglossing solvent for some plastics

Mixing and Application

1. Container underfilled for catalyst addition
2. Drill-mix base until uniform
3. Center mixer, form vortex, pour catalyst slowly
4. Mix 2–3 min (up/down + circular) until uniform
5. Apply: brush, roller, squeegee. Pour serpentine, spread, back-roll
6. Work time: 4–6 hrs (temp dependent)
7. Single coat preferred. Touch-ups after cure + solvent wipe

Coverage and Cure

• ~10 sq ft/quart on smooth surface (20 mil)
• Waterproof immediately
• Solvent evaporates per temp, not humidity
• Freeze before cure = no damage
• Sun accelerates cure. Final properties identical regardless of cure time.

EPDM Pedigree

EPDM rubber: radiator hoses, freezer gaskets, steam hoses, roofing membranes (60+ yr track record). Blended to improve other rubbers. PondPro2000 brings this proven polymer to liquid-applied waterproofing.
