I've been thinking a lot about this as I am doing a refinishing project
of my own. And have been doing research
. If it were me, I would sand, and varnish
. If you varnish
, you will need several coats, but you can do it in sections. Start with a 50/50 mix of Varnish and mineral spirits so that it penetrates well... and change the ratio to 75/50, then 100%. Varnish is hard, and VERY waterproof. So, if you spill water
, or have a bilge
back up, your floor will be protected. You will need to sand... vacuum up the dust, and wipe down with naptha, or mineral spirits to make sure you don't seal dust into the varnish. But, since it is high traffic... and needs to hold up to water
.. this really should be the best finish. I think the floor will be beautiful.
