    Default Nubuck: Re-dyeing

    Hi I'm wanting to customize some nubuck shoes and I was wondering if your dye-28 system with repeated use can change the color of black?
    Hi thanks for the reply here is a link to a pair done these started as a black shoe.
    This is along the lines of what I want to do.

    Most of the customizers are using Angelus brand dye's and paints.
    I like the idea of yours more as you have a better explanation of the chemical reactions.

    Please take a look at this kit and if you show some pictures I will help the best approach.
    Basic colours are available and customer colour is also available.

    Here are examples of redyeing suede (same as for Nubuck except difference in brushes and eraser used) from red to black.

    Three important points when comes to readying nubuck.

    1. There should not be any bronzing effect and the colour should stay solid black.
    2. The texture should remain as original with a “finger writing effect”
    3. No crocking or rubbing off of the colour.

    Leather Doctor Kit N7.cl – Nubuck Dye Refinishing Kit
    Leather Doctor® Kit N7.cl, nubuck dye refinishing kit is designed for dye refinishing after degreasing in a holistic approach. Most severely penetrated, prolonged and neglected stains from the bare head and hands that show a darkening effect with a sticky feel have its dyestuff probably deteriorated by the oil, grease and sweat. When the stain feels sticky, it is a sign of leather denaturing and reverting to rawhide from breaking of bonds with the tanning agent. When sign of dye is transfer to a white towel, it indicates that the dyestuff has also break bonds with the protein fiber. When leather is stiff or show signs of whitish residue migrating, it shows that the fatliquor is breaking bonds as well with the protein fiber. The main component of the leather protein fiber is amphoteric while the other constituents are not; shifting of the pH caused from sweat to alkalinity affects the pH imbalance. To revert from denaturing into rawhide prior to dye refinishing, contaminated alkaline soiling is removed with Degreaser-2.2, a waterbased (pH 2.2) multifunctional degreaser that emulsifies greasy contamination besides controlling dye bleeding and charging the protein fiber ionic positive for strengthening the attraction between the ionic negative tanning agent, dyestuff and fatliquor. Deflocculated and suspended soiling is towel extracted, thereafter rinse and pH balanced with Acidifier-2.0 to prevent the leather from reverting to rawhide. When leather feels sticky or slimy it is a sign of leather denaturing, a squeaky feel when wet is a sign of healthy leather. Hydrator-3.3 relaxes stiff leathers and removes surface tension free from surface blotchiness prior to fat and oil replenishing. Fat and oil is replenished with Fatliquor-5.0 to rejuvenate the leather for the desired suppleness when dry. Protector-S+ enhances a non-stick silky-feel to shield against sticky soiling. Note that the mentioned product suffix number denotes its pH value in this holistic leather-safe nubuck dye refinishing system. This kit comes with reduced weight option to save on shipping thus the 250ml concentrate ratio such as Acidifier-2.0, Hydrator-3.3 and Fatliquor-5.0 has to be filled up with distilled water prior to use.
