Is it possible to remove paste wax applied to a surface finished with shellac, and then applying more coats of shellac to finish the surface some more?
If yes, then:

- How do I remove the paste wax? With mineral spirits?
- Can I then just sand down the shellac lightly followed by applying another coat?
I have the same question, where I can I have used a scraper to get back to the wood. I am going to buy a bottle of Methylated spirit to see if that can remove the wax and Shellac finish.

I had to do a similar thing a while back on a piece with 3 coats of shellac followed by paste wax.
I used white spirit (mineral spirits in the USA I think) to soften the wax and then keep wiping with clean rags / paper towels and more white spirit until all the wax is removed.
The white spirit will not affect the shellac.

In the end I followed Bill’s approach and it worked well. I did not want to remove the shellac, just the paste wax so that I could apply additional coats. So I used mineral spirits to wipe off the paste wax, I sanded using 400 grit wet/dry sandpaper until I cut through the upper most layer of the shellac and then reapplied more shellac.
If you want to remove all shellac – which I also did on another time, I found that the best way was with a scraper card followed by sanding with 150 grit dry sandpaper once you reach the bare wood. I would not use methylated spirits as it would just create a gooey mess.17 July 2019 at 5:35 pm #590837David GillParticipant
I tried using the Methylated spirit which did not appear to have any effect I assume that I must have already removed the wax and if there was any Shellac left the Methylated spirit was not effecting it I thought that the Methylated spirit should have disolved the Shellac as that is what is used to make Shellac from flakes
