What is Shellac?

Shellac is a natural resin used as a wood finish and sealer in interior design.

Description

Shellac is a versatile finish derived from the secretions of the female lac bug, found in the forests of India and Thailand. It's processed and sold as dry flakes that are dissolved in alcohol to make liquid shellac, which can be applied to wood surfaces. Shellac dries to a hard, shiny finish, making it ideal for protecting and enhancing the beauty of wood furniture, flooring, and panelling.

One of the remarkable qualities of shellac is its ability to be applied over almost any other finish, allowing for easy use in restoration projects. It's also prized for its fast-drying characteristics and its natural origin, making it a favorite among environmentally conscious designers and homeowners. Shellac finishes can range from a clear to a rich, amber tone, depending on the type used, offering flexibility in aesthetic outcomes.

Apart from its beauty and protective qualities, shellac is also known for its ease of repair. Unlike polyurethane or varnish, shellac can be easily touched up or repaired without having to strip and refinish the entire piece, making it a practical choice for items that see frequent use or may be prone to wear and tear. However, it's worth noting that shellac is not as durable as some synthetic finishes and can be susceptible to damage from water and alcohol.

Usage

Shellac is commonly used in the restoration and finishing of antique furniture, where its natural composition and ease of application make it ideal for maintaining the original charm of the piece. It's also used in new furniture making, particularly in pieces where a classic, high-gloss finish is desired. In addition to furniture, shellac can be applied to wood panelling and flooring, providing a protective layer that enhances the wood's natural beauty.

Practical Application

Regular maintenance includes dusting and occasionally cleaning with a damp cloth, avoiding exposure to water and alcohol to maintain the finish's integrity.
