Leather Binder is a thin liquid filler that can be used to strengthen the weakened fibre structure of leather that is heavily worn or cracked. It can also be used on small imperfections in the leather such as scuffs and scratches, allowing the leather to be sanded smooth. The Binder soaks deep into the leather fibres holding them tightly together creating a stronger leather structure. This stronger structure greatly improves the tensile strength of the leather, which makes repairing leather easier and gives longer lasting results.
