stain or varnish or...
i have to re stain a wooden front door that has been baked by the sun to
the point that the stain behind the window in the storm door is a grayish color with a couple of good sized(4-5 inches long) cracks in the wood. the part of the door that is shaded by the bottom half of the storm door is in okay shape. i am planning on sanding the door with my palm sander but i am unsure about staining or varnishing after sanding..what is the difference between the two, also, it is an exterior door(with a storm door)how many coats? should i try stripping the existing stain vs. sanding? thanks, cj |

Varnishing is a protective top coat. When you varnish, look for something with UV inhibitors, such as Min Wax Helmsman poly. Sanding is good for the spot where nothing is left, but you may want to strip if in bad shape, such as cracking, checking, peeling. I'd put three coats of poly varnish on. |

The difference between stain and varnish - stain is color only, varnish is a clear coating that protects the wood. For wood doors with that sort of sun exposure, paint is a lot better - varnish has a sort of a "greenhouse" effect on wood - paint will keep sun off wood (in the shade, so to speak). If the cracks are all the way through the wood, you need to apply a flexible caulk or filler before finishing. Sand off the gray stuff. |

I recently managed to put my foot in the paint can (so to speak) putting clear polyurethane over oil-based stain--oops. Paint sounds like a better idea unless for some reason you want some grain showing through. I've done that hundreds of times, as have tens of thousands of others. What was the problem? |

It turned into a blotchy milky film, when I mentioned it to someone at the local Woodcraft he said he'd seen similar results before. The humidity wasn't high, I let the Minwax oil stain dry between applications and let the last one sit for a couple of days before putting on the Lawrence-McFadden poly. Of course with my generalized woodworking ignorance there could well be other factors I'm unaware of (that's usually a safe bet). |

The easiest thing to do after sanding is painting, That way you have no problems with the various absorption rates for the stain in the different parts of the old wood. |

After you do your initial sanding pass, wipe the door down with mineral spirits. It will color the wood just a little, giving you an idea of how it will look with finish on it. If you like the look, go ahead and apply the finish. If not, do more sanding. I recommend a spar varnish or spar polyurethane. "Spar" means the finish is appropriate for use on a boat's spar, which bends a lot, and the finish is flexible. A door that gets direct sun changes size during the day, so a flexible finish is a good thing. Also check for UV resistance. There is no permanent finish for exterior wood. They all have to be redone regularly. The best advice I've gotten, especially for west-facing doors, is to use a penetrating oil finish instead of a film-forming finish. With the oils, you just paint on another coat every six to twelve months. With film finishes, you have to sand or strip first. -- Steve Bell New Life Home Improvement Arlington, TX USA |

You need to strip it, sand it to new wood, and use a Marine finish if you want it to last, go to a real paint store to talk about it and read up, it can be a big job, even get bids from pros. |
