Topic tags/keywords: question I am finishing a project. I have 5 coats of dainish oil sanded to 400 grit between the last 2 coats. My question is do I sand again before I add a coat of poly? This is my first project in 19 – 20 years and then I only made a couple of picture frames/shadow boxes. -- Measure three times, cut twice. |

You will need to sand the project again. Poly adheres through mechanical bonding. So it will need a “roughened” surface to bond to. Just sand lightly with 400 grit, topcoat it with poly, wait overnight for it to cure and sand again before applying another coat. -- Challenges are what make life interesting; overcoming them is what makes life meaningful- Joshua Marine |

On the other hand…. You can’t go wrong following Scott’s advice, but I have applied poly over Danish oil many times without sanding first, and never had a problem. -- Charlie M. "Woodworking - patience = firewood" |

be quite certain that the oil is dry, 5 coats is alot of oil to be topping with a poly..personally i would wait several weeks, just to be safe, and yes sand it as stated above, and |

But not me i like your style! lol. but definately sand before the poly. hell by the time youve got 4-5 coats of poly on the peice has prolly doubled in thickness ;) -- mwm!

Thanks for the help gang. I will post it when finished, and after I get some 6 year old to show me how to use the digital camera and load it to the desktop. Again thanks for the info. -- Measure three times, cut twice. |
