Timothy Posted May 2, 2012 Report Share Posted May 2, 2012 I am refinishing my white oak kitchen cabinets. I have applied 2 coats of General Finishes water-based stain. Over that I wiped on a coat of Bullseye Sealcoat dewaxed shellac. I had planned on then sanding before applying several coats of Arm-R-Seal. When I began to sand the shellac with 320 it immediately burned through the shellac and through the stain. I was surprised it sanded off so easily. My next idea was to try 600. With 3 strokes of the finer sandpaper the finish had been burned through. Not sure what I am doing that the finish has burned through so easily. I know the shellac was thin as I had wiped it on. I obviously need the shallac as a barrier between the stain and Arm-R-Seal. Should I apply several coats of shellac (I believe they melt into one another and do not require sanding in between), or should I just not sand the single coat of shellac and just apply top coat over?

TimV Posted May 2, 2012 Report Share Posted May 2, 2012 You don't need to sand for the next layer of finish to adhere to shellac. However said, I do use a scotchbrite pad to remove dust nibs if needed. Quote Link to comment Share on other sites More sharing options...
duckkisser Posted May 2, 2012 Report Share Posted May 2, 2012 are you giving it enough time to set up and became a part of the wood? Quote Link to comment Share on other sites More sharing options...
fransikaner Posted May 2, 2012 Report Share Posted May 2, 2012 Like DK said, it almost sounds like the shellac is not penetrating into the wood. Are you sure you removed all the old films/finishes? Quote Link to comment Share on other sites More sharing options...
Grain Guy Posted May 2, 2012 Report Share Posted May 2, 2012 I Love shellac and love that sealer. It is thin and your just wiping it on(even thinner). You need to brush it out (I like my ox hair brush) the best you can 2 coats. If you get sloppy with your first coat sand your runs and brush strokes with 400 or 320 if you feel like you're not getting anywhere . If your gonna sand through, STOP, and coat again. Shellac is so forgiving. Cant put too much on, just too much on at one time is bad. Get a feel for it on some scrap if you want. Put as much on as you need to get a nice smooth sanding all over. Let it dry and completely cure before you apply your arm r seal (The longer the better, maybe a couple weeks if you can stand it. ).

AceHoleInOne Posted May 4, 2012 Report Share Posted May 4, 2012 Just curious why your not applying the Arm-R-Seal directly over the water-based stain? Should be no problem at all Did you use General Finishes water-based stain? 1 Quote Link to comment Share on other sites More sharing options...
