FIX DAMAGED LEATHER: A thick paste-based leather filler used for repairing damaged leather. Perfect for mending rips, tears, burns scuffs and holes. EXTREMELY FLEXIBLE: Fixes damage where a long-lasting and durable leather repair is required, so is suitable for high use areas. EASY TO USE: We recommend applying several thin layers of Heavy Filler to the damaged area filler, slowly building the filler up until it is flush with the leather. Once dry, cover over with our Leather Colourant or Leather Repair Paint. SANDABLE WHEN DRY: Once the filler has fully dried, it can be sanded smooth to ensure a nice, flush finish to the leather. USE ON ALL TYPES AND COLOURS OF LEATHER: Heavy Filler is a water-based product that can be safely used on any leather item, from furniture and car seats to jackets, accessories and shoes.
