Full details
The Prymax Pond Sealer is designed for pond owners and landscaping professionals looking for a robust, long-lasting solution to waterproof and protect water features. Its primary benefit is a high-performance, moisture-cured polyurethane formula that creates an exceptionally tough barrier against leaks and weathering, though users should note it requires a consistent three-coat application process for maximum efficacy.

FAQs
Does this sealer require a primer?
Prymax Pond Sealer is designed for direct application, but ensure the surface is clean and porous enough for the first coat to grip effectively.
Can I use this on a fish pond?
Yes, once fully cured, the polyurethane membrane is designed to be safe for water features, though it must be allowed to cure completely before adding any aquatic life.
What is the total coverage of the 5kg container?
Coverage varies based on surface porosity, but generally, 5kg is sufficient for a multi-coat application on a medium-sized residential water feature.
Can I apply it in direct sunlight?
It is recommended to apply out of direct, intense sunlight to prevent the product from drying too rapidly, which can lead to bubbling or uneven curing.
How long should I wait between coats?
Always refer to the specific drying times indicated on the container, as they vary based on ambient temperature and humidity.
Troubleshooting
Coating remains tacky after 24 hours
The ambient humidity may be too low for the moisture-cure process; slightly increase the moisture level in the area or provide more ventilation.
Sealer is peeling in certain areas
This is typically caused by insufficient surface cleaning; sand the area, remove all loose debris, and re-apply the three-coat system.

Setup, Compatibility & Care
Before application, ensure the substrate is clean, dry, and free of debris to allow the polyurethane to bond effectively. This product is compatible with most RAL BS 4800 and BS 381c color standards if pre-tinted materials are used underneath. To maintain the sealer, avoid using abrasive cleaning tools that could scratch the cured membrane. If the sealer is applied outdoors, monitor local humidity levels, as the moisture-cured formula requires proper atmospheric conditions to transition from a liquid to a solid state successfully.
