Spraying and Finishing
Preparation of the workpiece or surface is one of the most important things
Remove any plane marks with a scraper before sanding
Start sanding with #80 , then 100, 120, 150, 180. Finer than this leads to burnishing the wood. Clean off the dust before going to the next grit.
Ceiling tiles make good sanding blocks.
When the surface is ready you can start the spraying eg lacquer, varnish
If staining, it can be applied with brush, rag, spraying.
Start by applying with the grain and then with a rag go across the grain. The final application should be with the grain.
Spraying equipment
A good spray gun is important. One with a regulator to adjust the air flow and finish flow (eg paint, varnish, lacquer). The compressor should have an air reservoir so that you can adjust air flow.
Types of Lacquer
Nitrocellulose lacquer is what one usually uses.
It comes in three sheens: Gloss, Medium rubbed, and Flat
These lacquers are made from ??? with an acetone base(thinner). It dries by evaporation off the thinner which would be volatile ( acetone for example).
On the other hand varnishes dry by polymerization.
Spraying should be done at about 40 lbs pressure.When spraying inside a closed surface ,eg inside a drawer or cabinet, the pressure should be??????
Make sure that the lacquer is thin enough to spray” too thick will clog the gun and too thin will it will run n on the surface being sprayed. Hole the gun about eight (8) inches away from the surface. Always spray with the grain if possible. Spray beyond the ends of the workpiece so that you don’t get a build up of product at the ends. let dry. Sand between coats. Generally one applies 2-3 coats at least.
Use Stearate sand paper with Varsol to sand between coats and clean with rags and vacuums between coats.
For a polished finish one can use 600 grit wet paper followed by rottenstone and a light wax as a final step.
