I am refinishing the Mahogany on my 15 Super Sport. I sanded down to bare wood and the first 2 coats are 50% varnish (spar captians) and thinner. It is taking forever to dry. Will the 100% varnish dry faster? I am in central FL (Ocala) and the temp is around 65. This is a carport project. No indoor space for this type of work. thanks in advance. |

trainer, No, it won't. Welcome to varnishing. The 100% may actually take longer. Be patient, it will be worth it. |

I have some mahogany on my 16 foot whaler. What are the advantages of varnish vs teak oil? can you use both to refinish? |

Thanks for the help. To top off the slowness it has begun to rain for the first time in quite a while. Outrageman, I am following the guidelines and tips set forth in your article. THanks |

There is an excellent article in the REFERENCE section on wood refinishing: http://continuouswave.com/whaler/reference/whalerWood.html This article was written by Brian Blazer. |

There is a wealth of posts and threads on bright finishing - get a cup of coffee or a couple of beers and search. As regards drying time: variables are temp, humidity, possible contamination of surface (preparation) and differences of batchs. Best advice is to take a piece of sandpaper to test several areas that have been coated. If it powders up and doesn't gum up the paper you are good to go regarding scuff sanding for next coat. If it gums up, you must wait. I always make sure ambient air is moving gently while finish coats are curing. I sent a box fan up as far from the objects as possible, set on low, directed away from objects simply to keep room or shop air moving. Advantages to marine oil is much less preparation and criticality regarding preparation, application and multiple coats. Other advantage, especially over mahogany, is marine oil coats make an excellent base for spar varnish anytime even years later. Oil based spar varnish can always be applied over surfaces previously oiled. In fact, oil base coats have been used traditionally for as long as boats have existed. Multiple oil coats (assuming high quality and appropriate marine products or home-made oils) oxidize and create hard, resiny finish over time. Some commercial preparations have varnish in the formulations - you can do the same if you make it yourself. Good luck and have fun with your project. . |

I guess I neglected to ask the obvious question - how long is forever? Secondly, what kind of thinner are you using? Base coats should not take long to cure. Something is going on but advise how much time . |

The only factor I would add to Pete's list is the amount, or thickness of varnish being apllied per coat. My experience has been that if you apply the varnish too heavy, it will take forever to dry. Just enough of a coat to wet the surface, uniformly glossy. Building up the finish by multiple thin coats is better than a couple thick coats. Fifty percent thinner sounds like a bit much to me. Could be part of the problem. I never thinned varnish that much for a sealer coat, but maybe some of the experts could offer additional information on that. Rich |

Trainer, Have you been touching that varnish up each and every year since your original post? |

After Trainer varnished while it was raining, he spent months trying to get the varnish to be clear and glossy again.Last they heard, he ran off into the Okeechobee swamp fog,and they think he lives there now and talks to the animals a lot.His dog went with him.His wife sold his Whaler. |

Thats not the story that circulated around Disney World. From what I understand trainer sent jimh some pics. of his screwed up varnish job, and jimh banned him from the website on the spot. Trainer was so ashamed, he drove down to Disney World, and now spends his days walking around in a "Goofy" costume. Rich |
