Interlux Brushing Liquid 333 is a slow-drying marine paint solvent formulated to improve the flow of compatible Interlux one-part coatings during brush or roller application. It slows evaporation in warm conditions, extends wet-edge working time, and can also be used in selected Interlux surface preparation systems to remove sanding residue from fiberglass and wood surfaces.
When to Use Brushing Liquid 333
Use 333 only when the coating's technical data sheet specifically calls for it — including:
- One-part topside finishes where improved brush or roller flow is needed
- Marine varnishes requiring extended wet-edge time
- Selected antifouling coatings specified to accept 333
- Hot-weather application where premature flash-off is causing drag, brush marks, or uneven coverage
- Sanding-residue wipe-down on fiberglass or wood in compatible Interlux preparation systems
Compatibility Notice
Brushing Liquid 333 is not a universal thinner for all Interlux coatings and is not suitable for use on aluminum propellers. Always verify compatibility in the coating's technical data sheet before adding any solvent.
- Two-part polyurethane systems (e.g. Perfection) require dedicated reducers — see Interlux Reducing Solvent Spray 2316N for spray, or 2333N for brush (not currently listed)
- Some coatings specify Interlux Special Thinner 216 — confirm your data sheet
- For fiberglass surface prep and solvent wash, see Interlux Fiberglass Solvent Wash 202
Application Notes
- Confirm the specific coating's data sheet permits Brushing Liquid 333 before use
- Add only the amount specified in the technical data sheet — avoid over-thinning
- Mix thoroughly before application
- Maintain adequate ventilation and keep away from sparks, flames and ignition sources
- Wear solvent-resistant gloves and eye protection
- Allow wiped surfaces to fully evaporate before recoating

Parts Desk Insights
The most common purchasing mistake with this product is confusing 333 Brushing Liquid with 2333N Reducing Solvent — they are not interchangeable. Brushing Liquid 333 is designed for selected one-part coating systems; 2333N is a brushing reducer for two-part polyurethane products such as Perfection. Using the wrong thinner affects flow, cure time, and final finish quality. When in doubt, check the coating's technical data sheet for the exact solvent called out by product code.
