Recently I took some latex paint (Benjamin Moore) and mixed it with some water and floetrol. I sanded a sample maple cabinet door and applied paint wet with a brush. I waited a minute and wiped off. I then let this dry and sprayed a coat of shellac - let that dry. Scuff sanded - applied a water based glaze - let dry. I top-coated with clear lacquer - two coats. Everyone loved the look. I put a sample in my office and a potential customer walked in and said that was the color she wanted. This was all by chance. With this finishing schedule does anyone see a future problem - before I price this job out?
From contributor A:
The only problem I see is with the use of shellac as a sealer over latex paint, even though you wipe off the paint. Alcohol and latex are not usually compatible. I would watch for areas of pooling, edges, and raised panel areas. These would be the areas that would fail first. Make a sample of the exact door you would be making for this job and finish using this finish schedule and see what happens.
The water based glaze over the shellac may be providing a color shift (which you like) as the water would tend to cause blushing of the shellac. Not sure whether this could create a problem over the long term or not. You don't specify the type of lacquer used over the water based glaze but I would want to check for adhesion concerns on that step.
As DCS stated with these products combined you would have to watch for pooling of any areas of the latex which may have been left a bit thicker. All in all it seems that you could easily simplify all concerns by switching some of your materials. An oil stain for the latex with a sealer tinted amber to replace the shellac followed by compatible glaze and top coats. Still, if this works, it works. Just check out that adhesion durability issues won't be a problem and that what you are using won't slow down your processing due to having to be overly cautious on every step.
I've never had a problem since the only non WB product is Zinsser. If you keep it compatible it will work just fine and last for years.
