FAQs
Can I use this on previously varnished or painted wood?
No, this product is designed for bare wood only. Existing finishes must be completely removed before application.
Is it safe to use on wooden kitchen worktops?
While it provides a natural finish, it is not rated as food safe. For kitchen surfaces, consider specialized food-grade oils or sealants.
How many coats should I apply?
Typically, one or two thin coats are sufficient. Apply a second coat if you desire a deeper color and increased protection. Always allow 12 hours of drying time between coats.
What does 'hard dry' mean?
'Hard dry' means the surface is dry to the touch and resistant to minor abrasion. It does not mean the oil has fully cured, which can take several days or weeks depending on conditions.
Can I apply a different finish over the linseed oil?
Yes, once fully dry and cured, you can apply other finishes like varnish or paint, though it's best to test on an inconspicuous area first.
How should I store the remaining oil?
Store in a cool, dry place in its original, tightly sealed container, away from heat sources and direct sunlight.
Troubleshooting
Surface remains sticky after drying
This is likely due to excess oil not being wiped off. Apply a thin coat of white spirit to the sticky area, wipe it off immediately, and allow to dry fully. Repeat if necessary.
Color is too light
Apply additional thin coats of the linseed oil, allowing each to dry thoroughly (12 hours between coats), and wiping off excess each time. The ruby tint deepens with multiple applications.
Uneven color after application
Ensure the wood surface was uniform and absorbent. Lightly sand the affected area and reapply the oil, paying close attention to wiping off excess evenly.

Setup, Compatibility & Care
Application Method: Apply using a brush.
Compatibility: Ideal for bare woods, *except oak*. It can also be used to soften metal glazing putty.
Preparation: Ensure wood surfaces are clean, dry, and free from dust, grease, and previous finishes. For best results, sand bare wood smooth.
Application: Apply a thin, even coat. Work the oil into the wood grain. Wipe off any excess oil that remains on the surface after 15-20 minutes with a clean, lint-free cloth. Failure to remove excess may result in a sticky finish.
Drying Time: Allow approximately 12 hours for a hard dry. Ensure adequate ventilation during application and drying.
Care: Clean brushes immediately after use with white spirit. Dispose of oily rags responsibly, as they can spontaneously combust when dry; spread them out flat to dry before disposal or soak them in water.
