I’m ready to finish up a piece of furniture and have a question.

The piece is a combination mdf/oak. The mdf will be painted while the oak will be natural urethane. The paint is a Satin Impervo by Ben Moore – alkyd low luster enamel and the natural finish is a General Finishes Gel Topcoat – wipe on urethane.

There are a few areas where there is oak inlaid into the mdf. I plan to put on about 5-6 coats of the urethane over the oak inlays and then tape them off with a heavy clear packing tape. This will allow me to see and use an xacto knife to cut out around the inlays and give me edge to paint to. Once this is done, I will prime and then paint the remainder mdf body of the furniture (and over the packing tape).

Once I’ve put on 3 finish coats of the enamel paint, I will (carefully) peel off the packing tape. My concern is there will be a noticeable lip at the edge of the paint where the packing tape was previously. I’ve thought I could use a clear coat of something (?) and brush the entire piece of furniture painted and urethane surfaces. This would help minimize the “lip” at the paint edge at the oak inlays. I could very lightly sand the edge but I don’t want any paint dust to settle into the oak and not able to be removed. – or will it?

I know the enamel is a hardy finish coat but does anyone know of a compatible clear coat that I can apply over the enamel and urethane? Thanks!

A few guesses: putting heavy packing tape on the varnish will probably peel some (a lot) of it off when you remove it. That’s why masking tape doesn’t have a real strong adhesive. I don’t, however, have a suggestion on how to trim the tape to the edge; maybe if you used one of the thinner masking tapes you can do it. When you varnish the inlays, will you not mask them off? So the varnish will be on some parts of the piece which will receive paint? If that’s the case I suspect you will have an edge. Personally, I think it if you wait for the finishes to completely cure (weeks, not hours) I think you can gently rub the edge out. I also think a top coat isn’t going to help, but if you insist: let the finishes cure and you can apply pretty much anything, a clear waterborne like GF or Crystalac will not alter the color or yellow over time. Oh, the dust in the oak; shouldn’t be a problem (again, if the finish has cured). I suggest if you want to do as you plan, try it out on a mock up first and see what the results are. Impervo comes in both solvent and waterborne formulas (I think), which did you plan on using?
