There can be a problem using a finish such as polyurethane that does not
allow the passage of water vapour through whe hive wall. In damp conditions
(such as in the winter in the UK) moisture can can cause polyurethane
finishes to blister and become detached from the wood in places. It is
better to use one of the many modern woodstains that allow the wood to
breathe.
