1. Topic Explanation
Retouch varnish is a specific type of varnish used in oil painting to restore areas that have lost their shine due to oil absorption by the dried paint. It can be applied selectively or over the entire painting to even out the finish, restore the original saturation, and ensure a uniform appearance, allowing you to continue your painting process without visual inconsistencies.
2. Step-by-Step Guide to Applying Retouch Varnish
✅ Identify the Necessary Areas: Observe which parts of the painting have lost their original shine due to paint drying.
✅ Prepare the Surface: Ensure the painting is completely dry, free of dust, and clean before applying the varnish.
✅ Apply with Control: Use a soft brush, proportional to the size of the canvas, to spread the varnish evenly and avoid excess.
3. Application Tips
🎨 Be Mindful of the Quantity: Apply thin layers and wait for them to dry before considering an additional application.
🎨 Compatibility with Final Varnish: Ensure that the retouch varnish is compatible with the final varnish you plan to use to achieve a uniform and durable finish.
4. Additional Tips
🔍 Perform a Preliminary Test: Before applying it to the final painting, test it on a small area or a similar artwork to ensure the desired effect.
🎯 Use Only When Necessary: If you can complete your painting without using retouch varnish, that’s ideal. Use it only when there is a real need to harmonize saturation.
5. Reflection on the Use of Retouch Varnish
Retouch varnish should only be used as a saturation harmonizer, not as a final protective varnish.
🖌 Cleaning Brushes: Do not use only water and soap to clean your brushes after applying varnish, as this will not be effective. For Dartecor varnishes, use Turpentine, odorless solvent, or white spirit to properly remove any residue.
