This was a solid oak table which had fallen into a state of mild disrepair, perhaps due to the original finish not being of a high enough quality — we sanded it using our Mirka Deros dust-free sanding system, before applying four coats of varnish.
The photo was taken just after applying the first coat of varnish to one side: as you can see, oak is a light wood in its raw state.
This particular piece of wood has a characteristic figuring, which becomes much less visible with the application of each coat of varnish.
