I’ve got a sneaking feeling that it might have been over a year ago that I bought some Danish Oil to treat the wooden windowsills at home but it was only over the past few days that I got round to applying it (three sills and also the wooden top of a sidetable).
The upstairs ones were pretty easy – a quick bit of sanding (assisted the attachment on my oscillating multitool) and I could get on with applying some coats of oil. The windowsill in the front room turned out to be much harder work, as it turned out to have been previously coated with some kind of rubbery, wood effect sealant which didn’t sand off very easily. As I discovered over the course of the hour or more it took rubbing it down, if you sanded too hard, the heat would build up and it would seem to melt on the sandpaper, clogging it up.
I finally got there and, now it has had its three layers of oil, it is looking much brighter than it did before, as the old surface was beginning to discolour. Hopefully this will enable the windowsills to stand up well when condensation drips down on them and it will be easier to maintain in future.
