I'm refinishing a mahogany dining room table top. I plan to strip the old
varnish, sand thoroughly, stain, and cover with a high-gloss polyurethene. Question: Which is better, oil-based or water-based polyurethene? |

Question: Which is better, oil-based or water-based polyurethene? If you really want a top notch finish, use the oil base. If it is mahogany, no stain is needed, just the natural beauty of the wood. Thin the first coat about 25% with mineral spirits Sand with 220 grit Apply second coat, then sand with 220 grit Apply third coat and sand with 20 Apply fourth coat, let it cure a minimum of 2 weeks. sand with 400 grit Sand with 600 grit Rub with pumice Rub with rottenstone Wax Admire Yes, it is worth the time to do it right |

Question: Which is better, oil-based or water-based polyurethene? Water base cures faster, oil has more time to level out smoother. Water base probably wont be as impervious to a stain from a wet cup sitting. Gloss oil is a harder finish. Gloss is the right way to go as the dulling agent to make satin finishes makes the product cloudy, not as clear so it will hide grains beauty, and the dulling agent makes it softer. For a table I would use gloss poly over water base and do as Ed says. Or do the final coat in satin if you wish. |

Question: Which is better, oil-based or water-based polyurethene? Oil. It will enhance the natural color of the mahogany and is harder. Skip the stain, mahogany is too pretty to stain. Besides which, it's difficult to do a good stain job on something that's already been finished before. IMO, you would also do better with semi-gloss ...high gloss will show every imperfection. |

![]() "dadiOH" wrote Always apply full gloss poly. Let the last coat cure fully and then you can add a semi-gloss finish -- the quick way to do that is simply by rubbing the surface with #0000 steel wool and wax. The gives a semi gloss effect on the surface. If you use those other products, you'll have the semi-opaque effect through the entire depth of the finish which masks the natural beauty of the wood. Do you mean - seriously - that you can tell the difference between a piece of wood finished totally with semi-gloss vs. one finished with gloss except for the last coat? Sorry, I don't believe it. Not unless you put on scads and *SCADS* of semi-gloss coats. Anyone that is serious about nice finishes can. Really, they can. |

Yes, I can see the difference easily. 3-5 costs of gloss followed by one coat of semi-gloss? It's doubtful if I can see the difference in the finish. But why buy two types of poly? One can does it all! Hardness. The flatteners in semi-gloss affect the hardness of the poly. If the OP wants the most durable finish, he should go with a two part catalyzed water based polyurethane meant for floors. Traffic and Trek Plus are two brand names. http://woodworkersjournal.com/forum/...hp?t-8392.html The last post in that thread also addresses the apparent sheen of gloss with final semi gloss vs all semi gloss.

Joe Dries faster = doesnt level and retains brush marks. Yellow, my antiques look fine, unless he wants the Ikea look, but the practicability of the smoothest and toughest finish make oil the choise for wood workers that use a brush. |

That was my first though, then I realized you may have to buy a gallon of each to mix. Imron is a 3:1 ratio (and is about $300 a gallon) These come in 2 gallon kits http://www.ipaint.us/poguehbephib.html |

This is where I get it from: http://www.goldcoastflooring.com/Flo..._1_Gallon.aspx The catalyst comes in a pint container, and it's poured into the jug and mixed directly. It's a good system. There's a strainer screen in the cap and the jug is great for pouring it onto the floor. For smaller batches you'd obviously need a smaller mixing container. Pot life is something like six hours, so you can get ~three coats out of a mixed batch. R |

But his profit is in polyurethane. Try to spend that when your shopping. If it's too heavy to carry you can carry a Polyurethane Debit Card. But the store has to have a Polyurethane Modem or it won't work. |
