Key points

• Suitable for new or previously treated timber (old coatings must be fully sanded back).
• Apply in thin coats with a short pile roller, good quality brush or lint-free cloth.
• Approx. coverage: 24–28 m²/L (one coat), 12–16 m²/L (two coats), depending on wood type and smoothness.
• Typical drying time: around 4 hours under average conditions – ideally allow to dry overnight.
• Easy maintenance: marks or scratches can usually be touched up locally without full sanding and reapplication.

Application tips

• Let freshly laid wood acclimatise for several days and ensure moisture content is below 15%.
• Use 120 grit sandpaper to remove the existing coating; for an extra-smooth finish, add a final sand with 240 grit, then remove all sanding dust before oiling.
• Wipe the surface with methylated spirits to ensure it is clean before applying.
• Apply sparingly in the direction of the grain – tight-grain hardwoods generally need less product.
• If a second coat is needed, lightly de-nib between coats and wipe away any excess that doesn’t soak in.
• Always do a small test patch first and check colour and compatibility with any fillers or dyes.

Safety & cleanup

• Ensure good ventilation during application and drying.
• Stir thoroughly before use – do not thin.
• Clean tools with Barrettine White Spirit immediately after use.
• Oil-soaked cloths can self-combust: after use, soak them in soapy water and lay flat outside on a non-combustible surface to dry.

For day-to-day care, clean with a non-abrasive, pH-balanced cleaner and avoid harsh scouring creams or abrasive pads to help maintain the finish.
