Topic tags/keywords: spray lacquer

I have questions. I am familiar with spraying paint, but not lacquer. How should it look when it is wet? How do I know if I have sprayed enough?

Please include pics or references.

Get a mil gauge. The lacquer manufacturer will tell you how many mils to apply for each coat as well as total recommended thickness.

With a 1.5mm tip and a gravity feed gun, it is pretty easy to lay down a nice wet coat. Too thin / too quickly applied will give you orange peel. Too thick / too slowly applied will give sags or runs on vertical surfaces. Whenever you can, lay panels and cabinet doors flat, for the best results.

Thin the lacquer 10-15% with lacquer thinner, and practice on some scraps. Most novice sprayers move the gun too quickly. Slow down and spray in an overlapping pattern. Use a low angle work light and use the sheen you see to guide your progress.

I started by just spraying some old furniture, using various settings, etc. I don’t have a professional sprayer, but a HD general purpose type, as well as a touchup sprayer from HD. I would tape off sections and try different approaches; when dry, use remover , give it time to dry and try again.

One thing I love about lacquer is blending semi-gloss and satin 50/50 to get a luster level that I like (see some photos: http://lumberjocks.com/crmitchell/projects).

I don’t always get the result I am looking for the first try,but paint remover is plentiful. One comment above showed a mil gauge and suggested a spec sheet – here’s the one for PPG products that I use – http://buyat.ppg.com/rep_pafpainttools_files/Pghpaints/tdb/77-9110.pdf

One note about air temp. My first try was on a July 4 holiday and the temp was about 98. It was so hot the solvent was drying mid-way to the wood, and it all turned white, enter remover and start over. In this situation, you switch to retarder, but don’t expect to find it at HD or Lowes, as they have never heard of it. Mine came form the local PPG store. I don’t like it and don’t use it if possible because of the odor.

Speaking of odor, avoid the brushing lacquers, as the Delft products are terrible and it takes about a week for it to dissipate, during which it cannot come in the house !!! (unless you like sleeping in the yard with your project)

A nice shiny wet coat. It’s easier than you think.
