[Cob] linseed oil

[Tys Sniffen]

Anyone have brand/store recommendations for linseed oil for floors?

 

I know about the additives that create the 'boiled' vs raw, but I can't
really find good comparisons between the 'truly boiled' and 'chemically
boiled' oils. has anyone actually found the additives to be a problem? Or is
that just philosophical? 

 

And, I see different brands out there: Crown, Klean-strip, etc.  anyone ever
find any differences?

 

Finally, anyone have estimates on how much oil one needs to do 3 or 4 coats
for floors by sq foot?
