Facebook← Back to Which permeable flooring should I choose for car entrances?
When installing permeable resin-bound surfaces—especially where car entrances are involved—choosing the right binder is crucial for both durability and appearance. Non-yellowing polyurethane resins are a preferred choice for keeping your driveway bright and long-lasting.
Why Choose Non-Yellowing Polyurethane?
Outdoor resin floors are exposed to constant sunlight, vehicle traffic, and changing weather. Ordinary resins can become discoloured or yellow over time, especially when paired with lighter stone or pebble finishes. Non-yellowing polyurethane retains its clarity and colour stability, helping keep white and pale-coloured aggregates looking fresh.
Best Uses and Application Tips
Non-yellowing polyurethane is particularly well suited to areas where colour preservation is essential—such as driveways finished with white or light-hued stones. For those looking for a complete solution, the Flowstone Permeable Floor Kit specifically recommends non-yellowing polyurethane when using white aggregates. Always follow the resin manufacturer’s guidance for mixing and installing in suitable temperatures for a smooth, resilient finish.
When Non-Yellowing Properties Matter Most
If your project uses decorative whites or very light stones, or will be exposed to prolonged sunlight (such as car entrances and driveways), non-yellowing polyurethane prevents unsightly yellowing that can occur with some traditional resins. For coloured stones, a low-yellowing resin may suffice, but pure whites benefit most from this advanced polyurethane option.
