Non-yellowing polyurethane is a specialist type of resin binder chosen for its ability to keep flooring bright and free from discolouration, especially when using light or white stone aggregates.
Why Choose Non-Yellowing Polyurethane?
Over time, exposure to sunlight and weather can cause standard resins to develop a yellow tint—particularly noticeable on white or pale stones. Non-yellowing polyurethane is designed to resist this effect, preserving the original colour and brightness of the surface. This is particularly important for outdoor settings such as driveways, pathways, and patios with white or light stones where aesthetics matter.
Best Applications and Practical Tips
Non-yellowing polyurethane binders are recommended when installing resin pebble floors with white or very light aggregates. For coloured or darker stones, a low-yellowing epoxy binder generally suffices. Kits like the Flowstone Complete Permeable Floor Kit specify non-yellowing polyurethane for white stones to ensure the finish remains bright and visually appealing for as long as possible.
- Ensure substrate is clean and stable before application.
- Follow recommended mixing ratios for best results.
- Apply only within the suggested temperature and humidity ranges for optimal curing.
When Non-Yellowing Polyurethane Matters
Choose this type of resin when long-term appearance is essential and the floor is likely to be exposed to a lot of sunlight or outdoor weather. If you value lasting brightness for white or pale pebble finishes, it’s the most reliable option.
