Which Resin Type is Best for Split-Stone Effect Resin Floors?

Epoxy or Polyurethane: What’s the Difference?

When creating split-stone effect resin floors, the type of stone aggregate you use will determine the optimal binder. For coloured stone or dark aggregates, a transparent epoxy binder is typically best. Epoxy offers a clear finish that helps highlight vibrant pebble colours and protects the surface. Products such as the “Trasparente” Epoxy Binder provide excellent clarity and UV resistance for these applications.

When using white or very light-coloured stones, opt for a non-yellowing polyurethane binder. Polyurethane resins, like “Polirock”, are designed to prevent discolouration, keeping white aggregates looking clean and bright even after prolonged sunlight exposure.

Practical Selection Guidance

• For white stones or Carrara gravel: Use a polyurethane binder to avoid yellowing and preserve the original hue.
• For coloured or natural pebbles: Choose an epoxy resin for a glossy, vibrant finish that brings out the best in the aggregate’s tone.
• If you’re installing a mixed-colour surface, prioritise resin according to the lightest stones present to prevent yellowing across the whole area.

Considering a complete kit ensures you have the correct binder and comprehensive instructions for your project—explore options like the “Flowstone” Complete Permeable Floor Kit for an all-in-one solution.

When This Matters Most

Choosing the right resin is especially important for outdoor installations exposed to sunlight. Incorrect binder choice can lead to early yellowing or fading, with noticeable effects on white gravel surfaces. Proper selection keeps your split-stone effect floor looking its best for years to come.
