Top coat for outdoor stain??
I made a gothic bench from douglas fir and stained it. Assembly will
be made with wedged through tenons and tusked through tenons. I want to use it outside on our deck and realize from other projects that polyurethane doesn't quite hold up like I would want it to. Would shellac give a lasting protection on stained fir? I was thinking of a good quality car wax. At least that would not peel and I could apply as needed. Or, has anyone used something on the order of Thompson's waterseal on outdoor furniture?? Barry |

Barry I don't know of any film-forming finish that stands up to sunlight. The failure mode is peeling and flaking that allows the wood underneath to weather in patches. Not a pretty sight. I'd use a penetrating oil finish like Boiled Linseed Oil (BLO) or Tung Oil. You'll have to reapply occasionally depending on exposure, but it shouldn't require much surface prep. Beware that many finishes that claim to be Tung Oil, like Formby's or Minwax, are really varnishes with a little Tung Oil added to emphasize the grain. These will fail outdoors just like varnish.

I've had both good and bad results with poly so I'd not use it in most cases, especially direct sun. Best results I've had is with Penofin Oil. UV protection, no film, quick and easy to apply. |

There is nothing - NOTHING - you can put on it that won't require maintenance. Worst are film finishes (varnish, poly or alkyd; lacquer; shellac); easiest to renew are oils. Wax? Dunno, probably about as good as anything. -- dadiOH ____________________________ dadiOH's dandies v3.06... ....a help file of info about MP3s, recording from LP/cassette and tips & tricks on this and that.

I was thinking Spar Varnish, the stuff they made for boats that is now
used on exterior doors but then someone mentioned Penofin. Yup, that's what the pros would use. Penofin can come in colors too but just get the straight stuff. Any good pro paint sho[p should likely have it. On Nov 9, 5:27 am, "Barry Kwasny" wrote: I made a gothic bench from douglas fir and stained it.

(Cap Lock off) The epoxy protects the wood and the varnish protects the epoxy THe varnish/poly is simple to repair. Lew .. |

Lew,
Only 3 coats of Varnish ? All kidding aside - you did forget to mention it should be 'short oil' varnish. DO NOT, repeat NOT use 'Spar Varnish'. If you do, on a warm summer day you WILL glue your butt to the bench !! 'Spar' NEVER hardens . . . it's not supposed to. The idea was to protect wooden spars, allow movement & flexing, and yet be 'clear' to allow inspection of the mast, yards, etc. Regards, Ron Magen Backyard Boatshop "Lew Hodgett" wrote ...
