Solvent Polyurethane
The original timber floor finish. Amber warmth, proven durability, and a price point that suits budget-conscious jobs and specific species.
When solvent is the right call
Water-based polyurethane dominates new work and renovation specs across Australia, but solvent-based poly still has a legitimate place on certain jobs. The three scenarios where it earns its spot:
- Amber warmth is the brief. Solvent poly adds a warm amber tone to timber that deepens over time. On species like Tasmanian oak, pine, and cypress, that golden glow is exactly what the client wants. Water-based stays clear and pale -- which is a feature on some species but a disappointment on others.
- Cork floors. Cork reacts badly to the water in water-based finishes -- it swells, lifts, and distorts. Solvent poly coats cork without introducing moisture and gives it a durable, flexible film that handles the compression and rebound cork is designed for.
- Budget jobs. Solvent poly in 20-litre trade packs costs significantly less per square metre than premium 2K water-based finishes. On large rental turnovers, investment properties, and tenant-grade work, the cost difference matters.
The range
Handley Urethane 20L
Single-component solvent-based polyurethane from Handley Industries (New Zealand). Available in Gloss, Satin, Low Sheen, and Matt. A proven formula that has been on Australian floors for decades -- flexible, heat resistant, chemical resistant, and easy to apply with a roller or brush. The 20-litre pack size keeps costs down on large jobs. Coverage runs around 9 m² per litre per coat. Apply one coat of Rapid Seal underneath, then two to three topcoats depending on traffic.
Handley Urethane Rapid Seal
The solvent-based primer that pairs with Handley Urethane topcoats. Rapid Seal dries in approximately 30 minutes, seals the grain, and holds the timber at a lighter colour before the topcoat builds the amber. Coverage sits around 7-8 m² per litre. One coat is standard before the first topcoat. It is the equivalent of Bona Classic UX in the solvent world -- the sealer that makes the topcoat perform to spec.
Solvent vs water-based
The choice is not about quality -- both systems produce hard, durable floors when applied correctly. It is about the result the job needs. Solvent adds warmth, handles cork, and costs less in bulk. Water-based stays clear, cures faster, and meets the tightest VOC regulations. For a detailed side-by-side comparison, see the water-based vs solvent guide.
Ventilation and safety
Solvent poly releases higher VOC levels during application and cure. Adequate ventilation is essential -- open windows, cross-flow air, and respiratory protection during application. The building should remain unoccupied until the solvent smell dissipates, typically 48-72 hours depending on temperature and airflow. These are not optional steps.
