been using "used" vegetable cooking oil, yep the stuff used to deep
fry falafel and chips (French fries in Yankee), for years for exterior walls

love to get our hands on some citrus solvent instead of the turpentine. We did

is always present. In a place with continuous ventilation then its possible
that this technique could be used 'inside'.<o:p></o:p></p>

Hello!<br>
Just wanted to make sure you are aware of the difference between linseed oil,
and flaxseed oil. <br>
Flaxseed oil is edible, while oil marked linseed oil is usually not food grade.
Also, there is a difference between<br>
raw linseed oil and boiled linseed oil. "Boiled linseed oil" is no
longer actually boiled, but has added<br>
chemicals/dryers which make it dry quicker, and if reapplied and buffed, form
somewhat of a film finish. <br>
If you don't want to use thinners which emit VOCs, then don't thin your oil. If
you apply thin layers it will soak up and dry....eventually. <br>
Also, about the oil being food for critters; it polymerizes and at that time it
is no longer wanted as food...especially not when <br>
its bound to an earthen floor :)<br>
When it comes to the linseed oil staying tacky without exposure to warmth or
sunshine: it is true that the <br>
temp matters, it needs to be room temp. But, you also have to make sure that
you wipe off excess oil, <br>
or pooling. If you soak a surface, come back after an hour and rub the excess
off. Then, the next day, if you rub<br>
with a more abrasive cloth, it should not have that problem. I'm guessing you
could do this with a buffer pad/floor shiner<br>
on the large floor surface. <br>
We use linseed oil for many things here in Norway, and unlike my Canadian
"weather-brother", I would recommend<br>
using linseed oil, as I have seen beautiful results!<br>
