Buying Guide
- Choose gloss for vibrant color and dramatic shine; matte for reduced glare and a softer appearance. Some kits offer both options for versatility.
- Look for products labeled non-yellowing to preserve colors over time, especially on light-colored artworks.
- Quick-drying varnishes speed up project completion but require careful handling to avoid brush marks.
- If pieces will be exposed to light, UV resistance helps prevent fading or color shift.
- Ensure the varnish is suitable for your painting surfaces (canvas, wood, rocks, clay, etc.).
- Brush-on varnishes are common, but spray options exist. Brush-on needs smooth, thin coats to avoid streaks.
