What is Varnish?
Varnish is a clear, protective substance that is often applied over paint on both residential and commercial buildings. It’s a vital tool for painters because it helps to preserve the paint underneath it, making the color last longer and preventing it from peeling or fading. Varnish also adds a shiny finish to the paint job, which can make the color look even more vibrant and eye-catching.
Another reason why varnish is important in painting is because it can protect the surface from damage. This includes scratches, scuffs, and even water damage. By creating a hard, protective shell over the paint, varnish ensures that the surface underneath stays safe and undamaged. This is especially useful in areas where the paint might otherwise be exposed to wear and tear, like on floors or outdoor furniture.
