Leather filler is a specialized substance designed to repair leather materials. It effectively mends rips, tears, and cracks, restoring the original appearance and extending the life of your leather items.
Leather filler is a compound that consists of PVA glue combined with leather paint and finish. The compound is used to repair such leather items as shoes, boots, furniture, and auto upholstery. It is often available in a variety of colors.
Whether you need to repair a piece of furniture, a pair of boots, or a seat in your car, a filler will help get it done.
What is Leather Filler?
Leather filler is a substance used to repair and restore damaged or worn leather surfaces. It is typically a flexible, pliable compound designed to fill in cracks, holes, and scratches on leather items such as:
- Sofas
- Chairs
- Jackets
- Belts
- Wallets
- Shoes
- Boots
- Car seats
- Purses
- Handbags
Leather filler is used to repair scaly, cracked, or thinning areas where the leather is worn, and the backing or suede is exposed. It is especially effective for fixing items damaged by cat scratches.

On holes that measure larger than ½, most often, the leather filler is a water-based compound that can be applied easily. Although formulated to air dry, the time needed to cure can be significantly accelerated using an incandescent bulb or sunshine.
A leather filler is typically composed of a mixture of PVA glue with leather paint and finish. Since the leather filling compound is white, you will need to use a special primer and an airbrush to evenly and properly apply the compound to finish and strengthen the leather.
Popular Uses for Leather Filler

Fixing Cat Scratches on Leather
When attempting to fix cat scratches on leather, there are two routes you may take depending on the extent of the damage. If the scratches are very light and haven’t damaged the leather material itself, you may be able to use a leather recoloring balm.
However, if the area of damage is larger than the size of a tennis ball, you will need to use a leather filler kit. Most leather filler kits contain:
- Leather binder – which will work to strengthen the area
- Leather repair kit – which will fix the scratches
- Leather colorant kit – which will work to restore the leather’s original color

Leather Filler for Boots
If your leather boots are beginning to crack and look worn, you can bring them back to life using leather filler. You will need to check the boots for mold and mildew and then make sure to clean them thoroughly with saddle soap.
Next, moisturize the boots with mink oil, followed by applying your leather filler. Mink oil for boots enhances leather’s durability and water resistance while maintaining its natural suppleness. The filler will work to fill in the cracks in the boots, strengthening the leather and improving the appearance.
Leather Filler Shoes
For shoes and boots, it depends on whether you are filling light cracks or deep cracks as to how you will proceed. For light cracks, you should make sure you clean leather shoes properly and remove any dirt or grime that may be present. Then, condition the shoes and allow them to dry overnight.
With deep cracks, fill the cracks in with leather filler. You will then use sandpaper, sanding the entire area until it is smooth. You then have the option of applying a dye to deepen the color.

Perforated Leather Seat Repair
When repairing perforated leather, the process is slightly trickier because the perforations can complicate the application of adhesive or filler. It’s essential to ensure that any repair material does not clog the small holes, as this can affect the leather’s breathability and aesthetic appeal.
Begin by sub-patching any tears or holes present to provide a stable foundation for the repair. Next, apply leather filler to any remaining visible tears or holes, swiping the filler in the direction of the tear until achieving a smooth, level surface.
While the leather filler is still wet, re-punch the perforations in the repair area to maintain a natural appearance. Allow adequate time for the leather filler to cure completely. Repeat the process if necessary to ensure a seamless repair.
