Main Factors in Choosing Stair Resin Materials

Choosing the right resin or binder for resin stairs is essential to ensure a durable, safe, and attractive finish. There are a few key factors that should guide your selection for optimal performance in both domestic and commercial settings.

Prioritise Drainage and Slip Resistance

Stair surfaces must allow for effective water drainage to prevent puddling and reduce slip risks, especially in the UK climate. Permeable resin systems, such as those found in the Flowstone Complete Permeable Floor Kit, are designed to let water pass through easily while maintaining a grippy texture. This feature is especially valuable for outdoor stairs where safety is paramount.

UV Stability and Surface Compatibility

Outdoor stairs are often exposed to sunlight, so opting for resins with enhanced UV stability helps prevent yellowing and maintains the appearance of your stairs over time. Additionally, ensure the chosen resin or binder is compatible with your existing stair base—whether concrete, wood, or another material—to promote adhesion and avoid peeling or cracks.

When This Matters
