Hi – I posted an earlier forum about using Zissners shellac (which is NOT de-waxed) and need some help on figuring out what to apply as a sealant coat on top of the shellac to keep out water. Anybody have any suggestions? This is a plant stand that will take some abuse.

Thanks,
David

after regular shellac, put on dewaxed shellac, then anything you want like polyeurethane. It has worked so far on one of my projects.

Despite the hue and cry of Internet Experts, oil-based varnishes that are dissolved in mineral spirits or turpentine, will adhere to a non-dewaxed shellac foundation layer. There really isn’t much wax in most commercial brands of non-dewaxed shellac. If you are concerned, wipe down the dried shellac with mineral spirits before applying the top coat.

Water-based varnishes on top of non-dewaxed shellac is not a good idea.
