The Prymax Pond Sealer Black 1kg is a tough, single-pack polyurethane sealer crafted for safeguarding concrete-rendered ponds below the waterline. This black variant provides a robust, clean finish that is resistant to water, oil, and everyday chemicals. It creates a hard, non-absorbent surface that remains easy to clean, significantly reducing maintenance efforts and preserving the visual appeal of your pond over time. It's tailor-made for use below the waterline, contributing to the longevity and visual appeal of pond installations.

Beyond pond protection, the Prymax Sealer is also effective for damp-proofing internal render, plaster, and plasterboard. It proves versatile on dusty concrete floors and can be applied to internal wood surfaces and external walls, though it requires overpainting for UV protection. Designed for practicality and simplicity, this product requires no mixing, making application straightforward and efficient.

Application involves two coats of clear followed by two coats of black, each within a three-hour window of the one prior. If missed, it necessitates a 24-hour cure followed by light sanding before recoating. Its professional dark finish complements garden ponds and modern landscaping, making it a practical choice for new builds and refurbishments alike.
