Louis Vuitton shell-shaped bag vegetable-tanned leather restoration
1. Cleaning: Mix Aniline Cleaner with 10% Heavy-Duty Degreaser, dissolve in 10 times hot water and brush away dirt and grease.
2. Damage repair: After air drying, scrape the vegetable-tanned leather level with a horn scraper, then lightly wipe the area to be coloured with alcohol. The source stresses this step for adhesion. Sand minor damage level and apply Topcoat Finishing Repair Paste.
3. Colour mixing: Mix Smooth Leather Resin and High-Strength Colouring Resin at about 4:1, add 5% High-Efficiency Matting Agent and tint with standard colour paste. Set the matched colour aside. Add about 10 drops of Enhanced Curing Crosslinker when ready to apply.
4. Colour application: Use a spray gun. 1. Observe surface evenness while spraying. 2. If the applied finish looks shiny or artificial, increase the High-Efficiency Matting Agent until the gloss looks natural, then continue spraying evenly.
5. Colour fixing: Spray Aniline Extra-Soft Fixative to fix and seal the colour.
6. Additional correction: If gloss still needs adjustment after fixing, lightly spray a coat of Matte Fixative.
