Varnishing is the final step in completing a painting. It protects your work, unifies the surface sheen, and enhances colours. Understanding varnish options ensures your paintings look their best for years to come.
Why Varnish?
- Protection: Guards against dust, dirt, UV damage
- Unified surface: Evens out matte and glossy areas
- Colour enhancement: Deepens and saturates colours
- Removability: Can be removed for cleaning or restoration
When to Varnish
Oil Paintings
- Wait 6-12 months for paint to cure
- Thicker paint needs longer
- Use retouch varnish earlier if needed
Acrylic Paintings
- Wait at least 1-2 weeks
- Ensure paint is fully dry
- Apply isolation coat first (recommended)
