I have almost 200 square meters of lacquered floorboards in pine (?) in the dimension 95x21mm. They are slightly cracked in the tongue where nails have been, but fairly undamaged on the surface (except for normal 'patina'). Is it something that can be sold? What can you charge per square meter in that case?
It can definitely be sold. It works, for example, as roofing material. Half the price against råspont maybe, it could be around 30kr/square meter. More than that is probably not something to hope for.
How old are they? My grangolv from 1909 are indeed much thicker, but compared to modern wood, they are incredibly densely grown, if they are that old they should have value as flooring...
