How long must a Danish oil finish dry before top coating with a lacquer?—Peter Breu

Jon Siegel replies: Working with Danish oil requires good temperature control in your shop because the drying time depends entirely on the temperature. I would not put any finish on top of the oil until it has dried for at least three days at 70°. Below this temperature it will take much longer. Also, make sure the workpiece is kept warm for at least 24 hours before the oil is applied. If you fail to do this, expansion of air inside the wood will continue to push oil out of the pores onto the surface causing droplets that harden into blemishes.
