When did they limewash churches in Scandinavia?

Feb 2019
I know it was very common in Central/Western Europe to limewash castles and churches.

But when did they begin limewashing the churches in Scandinavian countries like Denmark?
Many of our churches are medieval dating to the 14th-16th century or earlier. Almost all of them are limewashed, but some few are not.

My question therefore is, did they limewash those churches in the Middle Ages? Or did they only limewash them much later - in the 18th century?
