That's very interesting Crash. I had always thought linseed and cottonseed were about the same. But they are not.
When you thin down your linseed oil, what do you use Piloon? Mineral spirits?
Mineral spirits = slow dry, lacquer thinner= fast dry.
Slow dry = deeper penetration
Fastest and most durable finish I added an artists product called Japan Drier: this on knives and gun stocks.
Now if you wanted to be real slow dry you'd use heating oil, but phew, stinks.
Boiled linseed oil has some driers incorporated, that or boiling simply thickens the product.
( I was an art supply sales rep and my uncle was a commercial artist, hence my knowledge source)
More recently I have been using a commercial product called DANISH OIL that combines all the features we want for natural finishes.
They generally offer pre-tinted as well as natural finishes.
Using a sponge, I wipe it on walls as a low gloss sealer,finish. Since using a sponge (which you can wring clean) you don't even need to clean off saw dust etc and it preserves tha natural wood look.
On floors folks simply mop on even coats and let dry. More coats= longer lasting finish, but to note on floors you'll never get a high gloss but rather just a darn good sealed floor finish. Kinda rustic 'tavern' look.(but low maintenance)
