Can I use the Purified Linseed Oil as a finish by itself?
Purified Linseed Oil can be used as a finish by itself and is excellent at hydrating dry new and old bare wood surfaces.
That said, it does not offer significant UV protection. Consequently, it should be mixed with the Authentic Pine Tar or the Linseed Oil Paint to create a Linseed Oil Stain on exterior wood surfaces. If used as a finish by itself, the Purified Linseed Oil will offer moisture protection and prevent conditions for rot and deterioration but aging, weathering, graying, etc. of the substrate should be expected.
Is this a problem?
The answer really comes down to personal preference but the breakdown of the substrate by UV exposure will take a toll on the integrity of the wood over time. It would be best to use the Purified Linseed Oil in conjunction with another traditional finish for exterior surfaces in terms of long-term protection and preservation.
For interior applications, the possibilities for using the Purified Linseed Oil by itself become much more varied.
It can be applied to nourish and hydrate wood flooring, furniture, cutting boards, carved utensils, butcher-block countertops, and many more.
As a finish, the Purified Linseed Oil leaves the grain open a bit more in comparison to the natural Linseed Oil Wax. It is easy to apply: simply brush or wipe a thin, even coat of oil onto a clean (as dust-free as possible) and dry bare wood surface. Allow the oil to soak in and before end of day, feel free to wipe off any excess before leaving to dry fully.
Repeat if needed.
Dry time is typically 24-48 hrs in 60+ degrees and with good air circulation.
To maintain, simply clean gently with diluted Linseed Oil Soap and clean water. Rinse, wipe down well, and let dry fully before applying a thin, even maintenance coat of oil.
If damage or discoloration needs to be addressed, surfaces can be cleaned more aggressively with undiluted Linseed Oil Soap. Scrub if needed, rinse well, wipe down, and let dry fully. Once completely dry, a little hand sanding may be necessary if the grain has raised. Vacuum and wipe down to achieve as dust-free a surface as possible. From there, apply a thin, even coat of Purified Linseed Oil and follow the application suggestions above.
Clean hands and brushes with Linseed Oil Soap.
Dampen and dispose of oil soaked rags to avoid a fire hazard.
Quick Tip: The natural Linseed Oil Wax is an excellent alternative to the Purified Linseed Oil as it closes the wood grain more, creating a matte, moisture-beading finish that is also easy to apply and maintain.
