I need to varnish the stairs, hall and landing and have a bit of a logistics problem. Short of shipping the animals out for a week and living in a hotel I can't see how to do this. I can only think of doing small areas at a time then boarding it over to protect it leaving a narrow walk way. Then next day doing the adjacent strip. I assume that oil based varnish will never go off if I cover it with a plastic sheet such as dpc.
