refined or cold-press linseed oil for earthen floor?

Hi! I couldn't find any info online about the polymerization of refined linseed oil. I am about to do the earthen floors with oil and beeswax and the refined oil is a lot cheaper than the cold-pressed. Like 6 times. Does anyone have any idea whether refined oil will work as well as cold-pressed to make a nice waterproof layer over the earthen floors?

My understanding about linseed oil is that the refined linseed oil (often referred to as boiled linseed oil) is treated with chemical drying agents that contain cobalt and manganese, which carry certain health risks. I'm assuming cold-pressed would also mean raw, which will take a very long time to dry. If it's anything like using raw oils on wood, it will likely be wrinkly. Apparently one can get linseed oil that is heat treated instead of chemically treated, I haven't looked into this yet. Hope this helps.

Cold pressed oil will take forever to dry and will probably stay sticky. Probably not a good choice for a floor.
