We have just installed an unfinished hardwood staircase in our bedroom, and are considering finish. We would like as natural a finish as possible (and easy/ quick to do) which can be readily repeated as necessary.
I think that a wiping varnish of some type would probably be the best in both above respects… and I am keen on the sound of Don Kondra’s ‘secret magic mix’ (if I can translate all the ingredients, but I’ll come to that…).
We do however have another problem – the staircase is made from a tropical hardwood – tauari (scientifically Couratari guianensis I understand), and it frankly stinks!! It has a fetid smell, which I suspect is like old swamps, where they probably grow. I note the Wiki entry refers to a fetid smell, so its honestly not just us really :)
Two main questions please:
Can anyone identify the type of varnish the spar varnish in Don’s recipe is (is is a traditional shellac or similar, is it a modern varnish such as polyurethane, or what)? I note references to ‘urethane’ not being suitable, but that is not a term I am familiar with on its own (is it the same as polyurethane?).
If I can come up with a suitable varnish and make and use the magic mix or similar, will it hold the smell into the wood? If not, will anything, and if so any ideas what please?(bearing in mind that we need to minimalise the work and want a subtle finish)?!
All advice gratefully received!
-- Where does the time go (its not around here!) ?
