Dewaxed shellac is an ideal sanding sealer. It bonds tenaciously to virtually any bare wood or finished surface; it dries very quickly, sands smooth with the greatest of ease, and since it contains no stearates it provides a reliable base for any kind of finish going on top.
One may also ask, how long does shellac take to cure? SHELLAC™ Top Coats should be cured for one minute in the CND™ LED Lamp (preset button 3) and two minutes in the CND™ UV Lamp.
People also ask, is shellac a good wood sealer?
Shellac really is like a universal binder. I like to think of it as a “clean slate”. A nice light coat of dewaxed shellac is a suitable sealer coat for pretty much any finish. I have used shellac as a sealer for pre-cat lacquer many times with great results.
Should I use shellac or polyurethane?
The ravages of time and use of a piece of furniture can be limited by a durable top or finish coat. While the terms varnish, polyurethane, lacquer and shellac are commonly used to reference a final finish in general, these products are not the same, nor are they recommended to be used interchangeably.
