Topic tags/keywords: deft lacquer hvlp spray finish finishing So…I got myself one of the HF HVLP guns. Spraying Deft gloss lacquer on walnut cabinets. Nothing like trying your first spray project on a full set of cabinets. But, I guess I am unsre of the “last step”. Should the last step be wet sanding, one last light spray coat, waxing? Some other step? I have been spraying outside, trying to view the finish in natural light from all angles to make sure I have it as even as possible. But I really don’t have any experience with spraying other than rattle cans on small projects. Any insight would be appreciated, thanks. |

I would caution spraying outside, there could be some interaction with the sunlight causing bubbles depending on the heat and conditions. If you haven’t had any problems so far then I wouldn’t worry about it but would keep an eye out for anything happening. -- Because I'm gone, that's why! |

I usually spray a 2-4 mil coat and lightly sand with 400G if needed between coats. I don’t do anything after the last coat on larger projects. However, it depends on the look/feel you are after. The finish can be rubbed out to increase the gloss or dulled if you want to decrease the sheen. Many people will apply a coat of wax to give a very smooth feeling finish especially on small projects like decorative boxes. I work all the way through my intended finishing schedule on scrap to ensure I will get the results I want before attacking my completed project. HTH -- Art |

Since the cabinets take up so much space, outdoors was my only workable option. The sunlight didn’t seem to impact the lacquer. However, when I was putting on the second coat of pure tung oil, the sun didnt do it any favors. I ended up having to re-sand a few of the pieces that were facing the light. It was a PITA. Probably would have been a good idea to get a few projects under my belt with the HVLP set up before diving in, but where would the fun be in that? Thanks for the insight. |

I like to wet sand the final (second) coat of lacquer with water and 1500 grit soft sponges. It leaves a glass smooth surface, without the mess of wax and steel wool. If you thin your lacquer 15-20% it will lay down really nice. -- Willie, Washington "If You Choose Not To Decide, You Still Have Made a Choice" - Rush |

Don’t know about the last step but the first I’d do is get a #4 ford cup and match your finishes vorticity to you nozzle size. Here’s a chart that will help with that. http://homesteadfinishingproducts.com/wp-content/uploads/2014/05/paintspraying_ver3.pdf -- Alaskan's for Global warming! |

I’m confused – you said you were spraying deft lacquer, then later make a reference to 2nd coat of “tung oil”. Slow drying “tung oil” varnishes kind of defeat the purpose of spraying. If you want lacquer, I would recommend a pre-cat lacquer – I’ve had very good luck with Sherwin-Williams. One of the nice things about lacquer (and shellac) is each coat “burns in”, melting some of the previous material, creating a contiguous coat – easy to fix screw ups. For the last coat, sand any rough areas or dust nibs with 400 or 600, and shoot a wet coat. Any rough areas or dust nibs in the final surface lightly sand with 600 or 800 and rub out the scratches. |

Nothing should be necessary after the final coat. I don’t wax cabinetry but I do wax furniture. -- Sam Hamory - The project is never finished until its "Finished"! |

It was a pure tung oil, not one of the varnish types. I put two coats on the walnut. Waited a couple of weeks and then sprayed the Deft Lacquer. I think I have them at an acceptable place now. So it will be the extra fun steps now…demo and electrical, plumbing. Just the fun stuff. |
