wiping stain inside boxes7/5
Staining the interiors on a rift white oak job. We are breaking down to flat parts as much as possible but need to wipe inside complete boxes on a couple cabinets. The stain is a thick pigment dark gray and shows light spots when wiped twice. Looking for techniques to blend corners and difficult areas. Thoughts?
A stain that shows lighter spots after being wiped twice means that the first layer has dried, and the second layer (coat) rewets it and pulls the pigment out.
You need to slow your stain curing/drying down. Anytime I'm staining, I keep a bottle of mineral spirits handy and use it to flood my wiping rag to help keep the stain's open time high.
You may find success by thinning the stain which you use inside the carcases maybe 30% with mineral spirits, but honestly most of my experienced stainers end up just squirting it on a rag. From that point on, it's just a matter of hand dexterity and good timing to make the final color look good and consistent.
Staining inside cabinets is always frustrating, which is why we almost always do it pre-assembly. We are forced into doing it maybe once or twice a year, and our company policy is that everyone bitches about it the whole time so that we don't do it again next year.
Spray it on, wipe it off. Keep the cloth very damp with stain. Use three levels of wipes, very damp, damp and dry.
It takes some time to keep pushing the stain around until you get an even coat. When you get to the damp cloth you are just trying to get excess stain up, move with the grain as much as possible.
After you get it dryish and the stain is more of less even you hit it with the dry cloth and do it with a light touch. Dark areas can be scrubbed a bit to lighten them up, but don't burnish the surface.
You have to keep swapping up cloths as they become more saturated with stain. The dry one becomes the damp, the damp one becomes the very damp and the very damp gets taken out of rotation because it has become to wet.
Leo is spot on.
We use an Astro(Star) mini gun for spraying stain.
Leave the backs off. Stain one side at a time by rolling the cabinet on the bench. Save yourself the trouble of working upside down and sideways. You are able to get a clean wipe and cut in the corners and no back to deal with. Leave the backs off to spray too. If the box has a face frame spray through the back of the box and hit the face frame dead on.
Mike J has it spot on...… if you have enough surface area to warrant throw it in a pressure pot and spray it on wipe it off with as low air pressure as possible...… add 10% butyl cellosolve to slow it's evap time down and you'll have plenty of time to get an even wipe
