After scraping off all the rests of glue, we decided to grind the floor.
And here we encountered the first problem: Of course we could have rented a big grinder and would have grinded the whole room within a couple of hours.
But that big machine would not only have stripped the floor but would also have flattened it - which we wanted to avoid. The planks are all uneven and we wanted to keep that historic structure. Therefore, my husband grinded every single plank with a small swinging grinder:
What a horrible job: noisy, dusty, backaching and it took him days... But I must admit that I really love the way he looks while doing it - like an alien ;)
And here is a first try at embedding a little video:
And a picture to compare the floor before (top) and after (bottom) grinding:
By the way: The length of the single planks is remarkable! They are about 5 metres long - all of the study's length!
Of course the now open-poured floor needed further treatment. We read a lot about different possibilites to treat a wood floor and talked to "our" carpenter. In the end we decided to do it the traditional and purely organic way:
First we lubricated it with linseed oil, which - nice side-effect - kills every wood worm, just in case there was still an active one in that floor...
Did you know it is dangerous to leave a cloth soaked with linseed oil in the house? It can catch fire!! Seemed quite scary to me and therefore I left all the jars we used outside in the yard before we disposed them. Better take no risks!
After lubricating we applied beeswax and then polished the floor with a hand floor polisher - a tool that my grandmothers both used as a matter of course but that is hardly purchasable nowadays. Thank goodness there is ebay...
And the result of all the labour is this:
I really love it!!
