I got a piece of acacia that was already oiled. I cannot specify what kind of acacia that is.
I cut it to size and sanded the surface smooth. As the sanding removed parts of the oiled wood, I applied some linseed oil (It was some left over from a can of oil bought from ikea. Called "behandla" and labelled "linseed oil". It is still available.)
I applied oil until the wood wouldn't soak it up any more. After that I let it sit for a few days with puddles of oil on the surface.
I wiped off the excess.
However, as soon as I first wiped the countertop with a wet cloth, it soaked up the water (I could clearly tell from the smell). The surface that was very smooth after sanding got rough again. The fibers of wood are noticeable on the surface.
It's not a problem for me, the wood looks rustic anyway.
Because this was the first time I ever did this, I would like to know:
- Should I apply more oil? I wonder how, because the wood soaked up as much as it could
- Can I get the surface permanently smooth by sanding and applying oil again? Wood is a natural material after all, that takes and gives humidity. Maybe it was dry and just needed a bit more water. Or maybe I have to adjust my expectations of what's possible with wood as a material?
- How do I keep the oil in the wood? I noticed that when I put something heavy on the countertop, the surface of the wood becomes oily. I think this is because the applied pressure forces the oil out of the wood
