For years now, I have been cutting, glueing, sanding staining and then sealing with lacquer. I don’t really get the film thickness I would like with lacquer though, so I was wondering if there was a step I was missing. I work exclusively with Red Oak if that makes a difference. My current lacquer application is 4 wet on wet passes, dry, buff with scotchbrite (purple) and then 4 more wet on wet passes to finish.

Couple of questions? How much are you thinning the laquer per application? What are you building that requires that type of depth and durability from the finish? Instead of the wet wet passes let a full dry take place between pass. Wet on wet is just pushing that previous layer around and really not drawing that much off whatever applicator you are using.

Have you worked with wipe-on polyurethane?

When I want a deep, glassy finish, my technique is to first build up a base with several coats using a foam brush, not worring too much about bubbles or brush marks. Then I sand this base out smooth, starting with 220 grit, then moving to 400 or so. This will leave you with a very smooth, but dull finish. Now you can carefully wipe on a final one or two coats with a soft cloth, and you should have a finish that looks like glass.

From my experience it takes many/several more coats of lacquer too get the depth you want. Let it dry between coats then sand with 400 grit until the surface of the lacquer is dull. When you get the depth you want skip any more 400 and polish until you get a perfectly smooth finish.

When you guys sand with the 400 grit between coats, is it dry or wet sanding?

There is a high build lacquer that will help. It is thicker and fills in the pores fast. As with any finish, sanding is very important. Also, it is imperative to let the coat dry thoroughly before sanding and recoating.

Filling the pores in an open grain wood like red oak takes many, many coats. Quicker to use a grain filler to speed up the porcess. Try it on some scrap pieces till you find one you like.
