Buying Guide

What finish should you choose?

  • Gloss varnish provides vibrant color and a shiny surface, ideal for emphasis and depth.
  • Satin varnish offers a softer sheen with less reflective glare, good for portraits or pieces where a non-glare finish is desired.
  • Matte varnish yields a flat, non-reflective surface and can mute color slightly; use when you want a muted or vintage look.

How much varnish do you need?

  • Small works: 150–250 ml can be enough, depending on textures and layering.
  • Medium to large works or studio use: 500 ml to 1 liter bottles are common to cover multiple pieces efficiently.

What should you consider for longevity?

  • Archival, non-yellowing formulas are preferable for long-term preservation.
  • UV protection helps prevent fading when pieces are exposed to light.
  • Self-leveling and non-clouding formulas reduce brush marks and surface imperfections.

How should you apply varnish?

  • Apply in thin, even coats using a clean brush, foam brush, or spray depending on product guidelines.
  • Allow adequate drying time between coats and ensure the artwork is dust-free before varnishing.
  • Test a small area first to confirm desired sheen and drying behavior.
