Overview

Aquascape Black Silicone Sealant is a premium, waterproof adhesive designed for ponds, water features, aquariums, and versatile outdoor projects. The rich black finish blends with liners, rockwork, and substrates, helping seams virtually disappear while remaining safe for fish, plants, and wildlife once cured. The tube delivers smooth, steady bead application and reliable performance for both hobbyists and professionals.

Built to handle real-world conditions, this sealant offers UV resistance and broad temperature tolerance. It remains flexible after curing, resisting cracking and hardening as outdoor elements shift with the seasons. The result is a durable seal that adapts to movement and moisture, supporting long-lasting results in a range of settings.

Key benefits

  • Fish-safe formula suitable for ponds, aquariums, and wildlife-friendly water spaces when fully cured.
  • Waterproof and UV resistant, with a flexible seal that adapts to movement and temperature changes.
  • Versatile for indoor and outdoor work—from sealing liner seams to crafting custom aquariums and repairs.
  • Rich black color helps conceal seams and blends with substrate, rocks, and liners for a seamless look.
  • 10.1-ounce tube with a Born on Date (BoD) on packaging; shelf life is 24 months after that date.

Best-use scenarios

  • Sealing pond liners and water features to prevent leaks and maintain a clean, cohesive appearance.
  • Creating or repairing custom aquariums, fountains, and other aquatic installations.
  • Landscaping and garden projects where a reliable, weather-ready seal is needed.
  • Indoor repairs and moisture-prone seals in homes or light industrial settings.

Storage tips: store upright in a cool, dry place and avoid freezing temperatures. For best results, surfaces should be clean, dry, and free of dust before application. Allow the sealant to cure fully according to the packaging guidelines for a durable finish.
