PU Thinner – Premium Grade is a dedicated solvent blend engineered for Jewell polyurethane sealers, primers and topcoats, delivering consistent application and a superior finish. It finely tunes viscosity for spray, curtain coater or brush application, ensuring excellent flow, levelling and smooth, defect-free films without sacrificing clarity, hardness or durability. System-matched to Jewell PU products, it helps prevent orange peel, blushing and poor intercoat adhesion that often result from using non-compatible generic thinners.

By supporting correct atomisation and helping coatings achieve the recommended dry film thickness, PU Thinner maintains uniform appearance and long-term performance on furniture, doors, paneling and premium joinery. It is also highly effective for cleaning spray guns, lines and tools immediately after use, reducing downtime and preserving equipment life in professional workshops. Choose PU Thinner – Premium Grade to unlock the full potential of your polyurethane wood coating system and ensure reliable, repeatable finishing quality.
