Take the tour ×  I have doors, patio furniture and windows which
all need constant attention in terms of varnish and wood
sealers.   What is the better choice between raw and boiled
linseed and should I rather use the polywax sealers that you get
in stores?  Essentially I would like to retain the lustre of the
wood.  share|improve this question I've never used linsoid oil
on any of my outdoor projects, so I am looking forward to seeing
if anybody has an answer. –  decker Feb 17 at 22:38 From the
resources on the internet, it says that linseed (flax oil), has
excellent sealing properties, applying it to my wood really
makes it look good and healthy, the only negatives i can see are
that the coat needs to be re-applied quite frequently, and that
the boiled oil can become sticky after a few coats. –  Hightower

fireproof container. The oxidation/polymerization that lindseed
oil undergoes is exothermic and can set things on fire. A thin
