stains

There are two types of stain and dye processes: Stain and Wipe and Stain without wiping. If you stain and wipe you can use most smaller tipped spray guns and simply choke down on the fluid delivery. However, for best control the smaller tip sets work better. For Stain without wiping you must use the smaller tip sets for even toning and shading. Choking down on a large tip set will not work well and you will have to wipe down. .

Toning and Shading: You need good breakup power and control for even toning and shading. We recommend Reduced Pressure or new conventional guns. These have the best break up power and tend to create very even stain distribution, especially if you are trying to color match. For open panel work and production, this is a great system. There is one problem. Getting into enclosed corners creates a hallo effect and unevenness as the air pressure pushes the stain to the side. This effect not noticeable with clears or pigments, but it is noticeable with delicate and transparent stains and dyes. Thus, when working with fully assembled cabinetry, we recommend HVLP, LVLP and AAA for a softer spray pattern. There is even a stain specific gun the VTX by Devilbiss which was created just for spraying stains in corners. We do not recommend this gun because it requires a lot of air, is limited to spraying stains and dyes, and is expensive. Unless you want a gun for a factory , for only one application, then we can recommend this gun. Otherwise it is unnecessary. Just a note: A trick is to leave the back off the cabinet and spray through. Then you can add the back later and not have cornering effect.

There are 3 types of stain classifications we use: Pure Stains and Dyes like NGR stains and alcohol dyes. These are like water. Suspended Stains which have a little body to them and consumer based stains like minwax which are like a thin lacquer in consistency.

Our suggestions are: Pure stains .8 pressure / 1.0-1.2 gravity feed
Suspended Stain .8-1.0 Pressure Feed / 1.2-1.4 gravity feed
Consumer based thick stains then you can use the thin stain recommendations 1.0-1.3 pressure feed / 1.3-1.5 gravity feed.
