Clear transparent boiled linseed oil in a 5.0 litre pack is a ready-to-use natural oil for nourishing, protecting and maintaining porous timber and for treating metal. The clear oil penetrates the material and enhances natural colour and grain without building a thick, sealing varnish layer. This generous 5 litre size is an efficient choice for larger timber projects, scheduled maintenance and multiple treatments. Boiled linseed oil is processed raw linseed oil that dries faster than raw linseed oil. It supports a moisture-regulating finish and is suitable as a finishing product for wood protection and metal protection. Apply the product thinly with a flat brush, let it penetrate the substrate and remove excess oil with a lint-free cloth. With theoretical coverage of approximately 10–15 m² per litre, this pack can treat around 50–75 m² depending on the substrate and application method. Apply the oil to a clean, dry, grease-free surface at temperatures of at least 5 °C. Safe working is essential: cloths and paper containing drying linseed oil can self-heat and self-ignite. Leave used cloths fully spread out to dry on a non-combustible surface, or keep them under water in a sealed metal container.

Key features

This large pack provides a clear, natural oil treatment for substantial maintenance and timber projects.

• Clear transparent finish: The oil keeps natural timber structure visible while enriching the wood colour.
• For wood and metal: Suitable as a finishing treatment for wood protection and metal protection.
• Ready to use: The oil can be applied directly without thinning.
• Moisture regulating: The treatment supports a breathable finish on porous materials.
• Theoretical 50–75 m² per pack: Based on 10–15 m² coverage per litre, depending on absorbency and application.
• 5.0 litre large pack: Practical for large surfaces, multiple items and recurring maintenance.

Applications

Use this pack for larger maintenance work and projects involving multiple wood or metal components.

• Larger timber structures: Treat suitable fencing, covered structures, façade details or garden constructions in accordance with product instructions.
• Extensive timber maintenance: Maintain larger quantities of wooden furniture, workbenches, frames and timber components.
• Weathered or dry timber: Nourish cleaned, dry timber that needs an oil treatment after weathering or drying out.
• Wooden tools and handles: Treat multiple wooden handles, shafts and utility items not intended for food contact.
• Metal components: Use as a protective finishing treatment on suitable metal parts in accordance with product information.

Suitable substrates

Use the oil on well-prepared, dry and absorbent materials.

• Porous untreated timber: Apply to bare timber that can absorb the oil evenly.
• Sanded timber: Treat large sanded timber surfaces after removing all sanding dust.
• Dry, sound exterior timber: Apply to dry wood without rot, loose coatings or persistent moisture exposure.
• Clean prepared metal: Use on dry, clean, rust-free or properly prepared metal substrates where permitted.
• Existing linseed oil finish: Maintain previously linseed-oil-treated surfaces after cleaning and light sanding where needed.

Instructions for use

Follow these numbered steps for a durable result and safe application.

1. Calculate the quantity required: Allow for theoretical coverage of 10–15 m² per litre and extra consumption on highly absorbent or rough substrates.
2. Clean the substrate: Remove dust, dirt, grease, loose wood fibres, non-adhering old coatings and moisture before starting.
3. Check application conditions: Work at a minimum of 5 °C on a dry surface and avoid application during rain, condensation or intense direct sun.
4. Stir the oil gently: Stir the contents carefully before and during use to support even application.
5. Apply thinly and evenly: Apply the oil with a flat brush or lint-free cloth, preferably following the grain when treating timber.
6. Allow the oil to penetrate: Give the substrate enough time to absorb the oil and avoid leaving large amounts sitting on the surface.
7. Remove excess oil: Thoroughly wipe away all unabsorbed oil with a clean lint-free cloth for an even, non-tacky finish.
8. Dry and ventilate: Allow the treatment to dry fully with sufficient ventilation; drying time varies with temperature, humidity and coat thickness.
9. Clean tools: Clean tools immediately after use with white spirit and follow the directions on the label.
10. Handle cloths fire-safely: Lay used cloths fully open on a non-combustible surface to dry, or store them under water in a closed metal container.
