Can shellac be used as a primer?

What’s the best paint to cover smoke damage?
Shellac is the best primer for smoke damage. It will mitigate all of the issues that a traditional oil primer cause. Shellac dries fast, blocks odor, adheres to various surfaces, and the odor dissipates quickly. We recommend applying two coats of Bin Shellac primer for all minor to mid-smoke damaged surfaces.
How do you encapsulate smoke damage?
Use just any paint primer.
Sealers are specially formulated for damage treatment and are the only coatings you can use to cover smoke damage and block smoke odors. Using an ordinary paint primer on smoke- and fire-damaged surfaces creates an incompatible situation and will only lead to further damage to the surface.
What happens if you paint over shellac?
Unlike painted cabinets, the glossiness of shellac does not hold paint well unless you prepare the surface before you apply the paint, requiring extra preparation. You must remove the shellac before applying the paint if you want to keep the paint from flaking off the surface at a later date.
Can you apply shellac over paint?
Can You Apply Shellac Over Paint? Acrylic will hold up fine by itself, but if you want a bit more shine, you can apply shellac, SealCoat, or water-based finish in an aerosol can after the paint dries.
Is shellac a good sealer?
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.

The shellac itself is not a problem, however the alcohol used to dissolve the shellac is extremely flamable, and the even the vapors produced by the drying and evaporating shellac are flammable.
Can I put polyurethane over shellac?
You can apply shellac over polyurethane even though this wonderful finish covers everything. This is so because it will stick to the poly just fine. The drawback is, poly is a soft/flexible material, while shellac is hard/inflexible, so if polyurethane moves, the topcoat (shellac) won’t move and can crack over time.
How do I protect my shellac finish?
Put a coat or two of a good hard wax on top and you’ll be all set. I cook up my own wax. I make it from carnuba wax with just enough bees wax to make it easier to apply and buff out, mixed with turpentine to keep the concoction soft enough. Wax over shellac is one of my favorite finishes.
How durable is a shellac finish?

Does shellac raise grain?
Shellac, or more accurately, the alcohol in shellac does raise the grain of wood, and there is nothing wrong with that. Once the first coat is dry, sand very lightly with 320 or 400 grit sandpaper to smooth the surface before the next coat.
Should I sand between coats of shellac?
You do not need to sand between shellac coats, but it can seriously improve the piece’s finish. That is because small imperfections like specks of dust get bigger and bigger every time you add a new coat. Shellac will bond with the coat under it, making one layer. Not sanding can leave you with a lumpy finish.
Can I shellac over wax?
You need to get the wood as clean as possible. Even so, you probably won’t get all the wax out of the wood’s pores, so after you have cleaned the wood as well as you can, brush or spray a first coat of shellac. The shellac will still bond well to wood with a little wax residue left. Be sure the shellac isn’t real old.
