Leather is a strong and versatile material that can last for years. You can dress it for an elegant appearance or play it down to appeal to its rugged side. However, despite leather's durability, it's not imperishable. Even the best quality leather will start to peel or flake if it's in constant contact with abrasive surfaces that repeatedly rub or create friction. You can repair the peeling leather yourself on a small item such as a belt.
Damp a cotton ball and gently wipe down the flaking area. Allow it to air dry.
Rub the abrasive pad included in your leather repair kit back and forth across the peeling area. Your goal is to buff off all the flakes so that the area takes on a bald, slightly patchy look.
Mix the paints included in the kit with a plastic knife on a paper plate. Take your time as it's important to match the colours perfectly.
Dab the paint onto the leather belt with the brush or applicator included in the kit. Press grain paper against the leather paint. Use the type of grain paper that matches the leather grain of your belt.
Heat set the leather paint with an iron on medium heat. Most kits will ask that you apply heat for just a few minutes. Allways check the directions for the specific kit you're using. Remove the iron and peel off the grain paper to reveal your good as new belt.
Most, but not all, kits include grain papers. Look for grain papers in major shops. Some kits will have a clear coat for you to apply over the paint.
