To “nourish”, sustain or maintain leather is to prevent it from starving of its original 15% fullness of fatliquor. The percentage of fatliquor (fat and oil) in the leather diminishes as the leather ages right after the tannery, converting the raw hide into leather. The main purpose of this fatliquor in the leather structure is to impart suppleness and prevent creases developing that eventually progresses into cracks and loss of tear strength. Fatliquor is the lifeblood of leather, with frequent nourishing will prolong the original perpetual usefulness of the leather. Tips is to hydrate the leather to relax its leather structure prior to fatliquoring it with Hydrator-3.3 > Fatliquor-5.0 system.
To “condition” the leather for a buttery-feel, non-stick surface Leather Protector-B is recommended.
