"Water-based lacquer notes
Thursday, April 16th, 2009
We just started our 100th instrument, and I finally feel like I’m starting to master the application of the water-based lacquer. It’s not as good as nitro, but that is the nature of the product. It’s harder to apply, a bit more finicky, and it doesn’t give you as “wet” a finished look. But, given all the positive impacts to your health and the environment, the water-based lacquer is excellent. So, here’s my process:
* I use Stewart-MacDonald’s water-based laquer product line. I tried KTM-9 (from LMI), but it is more finicky. The big negative is that when you use shellac as a sealer and don’t need a pore filler (such as on spruce), the KTM-9 easily blisters during buffing. The StewMac products are really solid, and the folks at StewMac have done a lot of testing. They are a great help.
* I sand to 180, then mask, then put on one coat of shellac as a sealer.
* After a quick sanding, I put on StewMac’s water-based (clear) pore filler. I mix some micro-beads into the pore filler to thicken it a bit. This is a really important step–it reduces the number of times you need to pore fill and results in a much better surface.
* One day later, I put on another coat of pore filler thickened with micro-beads
* One day later, I sand it flat with 320. I put on 5 coats of the StewMac sanding sealer at 45 minute intervals. I’m using a Walcom STM HVLP gun and I put on relatively light coats. I never get any runs or sags, and I overlap each pass of the gun by 50%. I leave the product in the cup of the gun during the day and clean it out after the last shooting. I keep the room at about 70 degrees and the humidy fluctuates during the year from about 35% to 45%.
* The next day I sand everything flat with 320. This is the biggest sanding day. I don’t want to sand through the finish and expose new pores, but I want to get it as flat as possible. Some pores still show up after this sanding. I think put on another 5 coats of the sanding sealer.
* The next day everything gets sanded flat, and you shouldn’t see any pores. I then put on 5 coats of the StewMac water-based lacquer at 45 minute intervals. Again, the coats are relatively light. If you get runs or sags, or you see any milky look to the finish, then it’s going on too thick.
* I wait about 7 days before sanding & buffing.
* I go right to 1500 grit wet-sanding. Surprisingly, the surface right off the gun is so good that I can sand with 1500. This sanding goes pretty fast.
* Then I go to the buffer and buff with the Menzerna medium, then extra-fine.
With this process, I get a great gloss finish. StewMac notes that to get as transparent a finish as possible, keep each coat of finish light.
