G4 Pond Sealer – 1 kg – Clear or Black
Deep-Bonding Concrete Sealer for Ponds & Water Features

 

Bonda G4 Pond Sealer is a high-performance, deep-bonding plastic coating specifically formulated to seal concrete ponds and water features. It locks in free lime within the concrete, helping to prevent leaching that can raise pH levels and harm aquatic life.

Designed for professional use, G4 can be applied without a primer and performs reliably even at low temperatures, making it ideal for UK conditions.

 

Why G4 Is the Correct Sealer for Concrete Ponds

  • Seals in lime – protects water quality

  • Deep-bonding formulation – penetrates concrete for long-term performance

  • No primer required – faster, simpler application

  • Low-temperature application – extends working season

A proven solution for new builds and refurbishments.

 

Material & Performance

  • Forms a durable plastic coating

  • Strong adhesion to concrete surfaces

  • Creates a waterproof, long-lasting seal

  • Suitable for permanent submersion once cured

Commonly used by professional pond builders and landscapers.

 

Typical Applications
