Varnish

Varnish

Definition

Varnish is a protective, resin-based coating applied to wood or other substrates to provide a durable, glossy, satin, or matte finish. It enhances the appearance of the wood while protecting it from moisture, dirt, and wear.

Characteristics

• Provides a hard, protective surface over wood or painted finishes.
• Available in gloss, satin, or matte sheens.
• Can be oil-based, water-based, or synthetic.
• Dries clear, preserving the natural color and grain of wood.

Applications in Framing

• Finishing picture frame mouldings for both protection and aesthetic appeal.
• Used on wooden panels or substrates before or after painting.
• Protects frames from scratches, moisture, and aging.

Best Practices

• Apply thin, even coats and allow each coat to dry before applying the next.
• Sand lightly between coats for a smoother finish.
• Use in a well-ventilated area, especially with solvent-based varnishes.
