Furthermore, does shellac Harden?
Shellac doesn't cure so much as dry out. There's no chemical change that makes it into a hard layer, just that all the solvent, usually alcohol, has evaporated out of it, leaving the solid resin behind. I've seen shellac harden in seconds under really warm conditions.
Likewise, what does shellac do to wood?
Shellac is the easiest of the classic finishes to apply. It produces a very fine, mellow finish, and it accentuates the natural grain of the wood. It is especially attractive on walnut, mahogany, and fine veneer woods. It polishes well and is the basis for the traditional French polish finish on very fine furniture.
A: Shellac will adhere tenaciously when applied over almost any other type of clean, wax free, and oil free finish. To seal wood before applying polyurethane or other finishes, Bulls Eye® SealCoat™ is a shellac-based universal sanding sealer that is 100% wax-free.
