    Default Aniline (Full) – Restaurant Bench Seat – Cracks, Splitting, Worn, Stretched – How to save from the inevitable reupholstering for a good few years?

    I am hoping that you can guide me on which product to purchase.
    I am trying to strengthen many small cracks and a number of deep cracks that are in danger if splitting on a long restaurant bench seat.
    I don't know specifically what kind of leather it is other than it has a smooth wipeable surface.
    It is a deep green color that has faded on the seats from years of use.
    The leather has also stretched significantly.
    I am not trying to make it look new again, just trying to save what is there and put off the inevitable reupholstering for a good few years.
    I have looked at your products and am wondering if Impregnator-26 or Stucco-90 would be effective.

    >>> I don't know specifically what kind of leather it is other than it has a smooth wipeable surface.

    This is the best quality among the pigmented leather. The smooth surface indicates full-grain leather that has the strength greater than other corrected grain or embossed leathers. Other lower quality pigmented leather would have lasted until now. If the reverse suede side is also green in color then we have positively identify this leather as semi-aniline.

    What is Semi-Aniline Leather?
    Semi-aniline also known as micro-pigmented leathers have all the qualities of aniline leather but also have a light micro-pigment finish and topcoat applied. This additional micro-pigment finish and topcoat increase UV light and water resistance. Micro-pigment is applying finely grounded pigment finish to aniline leathers to even out the difference in color absorbency intensity. Full-grain leathers that are colored with transparent aniline dyes and are micro-pigmented are classified as semi-aniline.


    >>> It is a deep green color that has faded on the seats from years of use.

    Recommended color restoration is with Micro-54 system that comprises of Adhesor-73 > Micro-54 > Micro-Top-54 > Protector-B+

    Leather Doctor Protector-B+
    Leather Doctor® Protector-B+, a buttery-feel with a classic leather scent is design for pigmented, aniline and nubuck oil pull-up leather types. This is a non-film forming, non-stick, rub-resistant protector that enhances a soft natural tactile feel for imparting a breathable barrier essentially to shield the detrimental effects of sticky soiling and preventing the too common pesky ballpoint from ever ready rolling out its nasty ink. Moreover, for helping to release those tenacious blue jeans dye-transfer stains obviously on light colored leathers easily. Its natural buttery-feel protection increases the leather resistance to wet and dry rubs, thus reduce stretch; scuff and abrasion with reduce friction squeaks.


    >>> The leather has also stretched significantly.

    A buttery-feel smooth surface reduce noise, cut surface friction thus translate to less stretch. This is done on a routine basis by application of Protector-B+, without the leather scent is to use Protector-B (scentless is without the plus sign). Stretching out is partly due to diminishes fatliquor in the leather structure where the fibers collapse and begin to stick together. This is rejuvenated with Hydrator-3.3 > Fatliquor-5.0 system. Hydrator-3.3 helps to relax the fibers, shrink back and open the inter-fibrillary air spaces preconditioning it for ease of fatliquor replenishing.
    Impregnator-26 plays a part in further tightening up the loose structure from over stretching again.

    Products recommended for this process:

    The multi functional abilities include:
    a) to check for surface tension for an even appearance free from blotchiness prior to fatliquor replenishing.
    b) To plumps, relaxes and separates crushed, shrunk and stick together fibrils for manipulating away-unwanted creases and wrinkles.
    c) To rectify alkaline overexposure areas by facilitating colloidal water movement to redistribute the leather constituents from surrounding areas.
    d) To activate the dormant dyestuff within the leather structure for color refreshing.
    e) To facilitates colloidal water movement within the inter-fibrillary spaces for wicking foreign soiling particulates to resurface.
    f) To stabilize, pH balance and charge the protein fiber below its iso-electric point (pI) ionic positive to hydrogen bond with the ionic negative fatliquor more effectively.

    Leather Doctor Fatliquor-5.0

    Leather Doctor® Fatliquor-5.0, a micro emulsion of fat, oil and water is an anionic charged pH 5.0 fatliquor for rejuvenating all leather types. It relaxes coarse breaks, creases and wrinkles enhance suppleness and prevent cracking. It softens the leather with stretchability, compressibility and flexibility, while enhancing its rip tensile strength greatly. It is for replenishing the original fat and oil that diminishes thru sun-bleaching, ageing, heat and alkaline overexposure or cleaning. On application, the water-encased molecule breaks free when hydrogen bond attraction takes place between the fat and oil with the protein fiber. The excess free water content wicks out leaving a breathing space behind for leather natural transpiration. The fat plumps the leather with fullness from easily collapsing into creases and wrinkles during stress or flex, while the oil lubricates the fibers so that they slide over one another smoothly like millions of inter-connecting hinges. Thus helps to keep leather at its optimum physical performance and prevent premature ageing. This universal Fatliquor-5.0 is for all leather types including pigmented, aniline, vachetta, nubuck, suede, hair-on-hide and woolskin.
