I live in a flood and hurricane zone and have been through a number of hurricanes and have learned the value of creating highly water resistant, if not water proof furniture. After Andrew I lost an entire oak paneled room to roof damage. I used Tung oil and deeply regretted that decision as the entire room was ruined. OTOH, a maple plywood vanity in bathroom was completely done in urethane varnish, was wet for three days and sustained no damage. Neither did any of my floor furniture.
For these reasons I’ve been committed to varnish. However, a recent large project in an open grain wood proved far too time consuming for me to get the grain completely filled and I do not like filler stains and don’t use stains of any kind. For open grains I’d prefer to leave the grain open and use something else that would withstand water as well as varnish. I coat virtually every part of my furniture except for glue joints before assembly. Is there any other finish that is as water proof as varnish?
