Ensure surface to be oiled is smooth, clean, dry and free of contamination. For surfaces previously treated with oils or waxes clean back the surface to bare timber with fine wire wool and white spirit, working along the grain.


Ensure the product is thoroughly shaken prior to use. Apply oil liberally by brush or rag. Leave for a few minutes for the oil to absorb into the wood then wipe off any surplus. Allow the oil to dry overnight before using or recoating. When applying to new wood thin the first coat with 10% white spirit.


Maximum 10% white spirit.


If used on exterior projects regular maintenance will be required to keep the wood nourished. On previously sealed surfaces some oils may dry to a slight gloss. This can be reduced by gently rubbing the surface with fine wire wool and wax polish, working with the grain. Not suitable for use on oak.


Up to 10m² per litre per coat. Will depend upon porosity of the wood.

Drying Time

12 hours. Drying times are based on an ambient temperature of 20°C and 50% relative humidity. Lower temperatures or higher humidity will prolong the drying and overcoating times.

Clean Up

Take extra care as application cloths and soiled cleaning rags may self ignite without warning. Lay cloths out flat in single layers to dry, or wash out thoroughly in warm soapy water before disposal. Remove as much product from application equipment as possible before washing with white spirit. Do not empty into drains or water courses. Some local authorities have special facilities for the disposal of waste coatings.


Store in a dry, safe place. Do not store in environments where extreme temperatures may occur. Keep within 5-30°C. Do not store in direct sunlight.

what do i use on oak, if not blo? I have indoor windowsills that need to be treated. They have been stained and previously treated with mineral oil, but I am looking for something longer lasting.


Blackfriar Boiled Linseed Oil is not suitable for use on oak, the acidity of oak will react with the oil causing it to darken significantly. We're not sure what is meant by mineral oil, previously used, if this is a non drying oil it may react with any type of coating applied over the top. Blackfriar Danish Oil may be an option however a test area will be necessary over the oil coating. Wipe the surface thoroughly with white spirits to remove oil residues then apply 1 coat of the Danish Oil. Check to ensure the Danish Oil dries to a tack free finish. There is the possibility of any residual oil reacting with the Danish Oil preventing it from drying. Provided the coating dries OK a second coat of the Danish Oil can be applied.
