Properties of an Ideal Varnish

The properties of an ideal varnish are as follows:

1. It should always provide a glossy surface and be pleasing in appearance.
2. It should dry fast and provide a uniform finished surface.
3. When exposed to the atmosphere, the colour of the varnish should not fade.
4. The developed thin film on the surface should be tough, hard and durable.
5. During or after drying it should not show cracks or shrink.
