    Default Restoration Hardware Maxwell Sofa Brompton Coco

    I purchased a used leather sofa and it was in decent condition with some soiling on the seat cushions and back cushions. I did some research and applied Honey Leather conditioner to hydrate the leather (added three coats) and it seemed to help and it did darken the leather. Almost all of the wax pull up shine was gone so I applied a product called Wax It by Black Jacket. The product left the leather with a milky gray residue and tacky to the touch. I used a blow dryer thinking it would melt the wax in and I could buff to a shine. Still tacky and really did not buff well leaving the leather with a gray dull dry look. I proceeded to use Honey Leather cleaner to try and remove the product. I seemed to get a lot of material removed and the tacky feeling is minimal. Unfortunately the leather is dull, darker, and is some spots feels very rough. With one of your kits can this couch be saved and returned to a shiny condition? How do I remove the Honey Leather Conditioner and “Wax It” products so I can start over if possible? Name:  DSC03746.JPG

    >>> Unfortunately the leather is dull,
    AnilineTop-76G will restore the shine.

    >>> darker,
    The Honey Leather Conditioner stuffs up the pores or breathing spaces that gives the darkening effect (leather should breathe - known as transpiration).

    >>> and is some spots feels very rough.
    Roughness is probably due to abraded surface and smooth out by AnilineTop-76G in between sanding.

    Stripper-2.3 > Acidifier-2.0 system.

    >>> I seemed to get a lot of material removed and the tacky feeling is minimal.
    The end result of removing unwanted products should produce a “squeaky” feel - Acidifier-2.0 help pH balance if the tacky feels comes from the denatured (or pH imbalanced) leather, leather has a pH value of 3 to 5 and any alkaline liquid will affects its ionic charge negative (-ve). Because all the leather constituents like the tanning agent, dyestuff and fatliquor are all ionic negative (-ve), just like a magnet like poles repels.

    Leather Doctor®, aniline wax pull-up leather dye refinishing kit, is designed for dyestuff and topcoat refinishing, after degreasing, in a holistic approach. Most severely penetrated, prolonged and neglected body stains from bare head and hands that show a darkening effect, with a sticky feel, have its topcoat and 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 color 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 mainly caused from sweat to alkalinity affects the pH balance. To revert from denaturing into rawhide, prior to topcoat 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 (+ve), for strengthening the attraction between, the ionic negative (-ve) 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 denaturing. 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. Surfactant-3.6 is used for Aniline-21 dyeing pre-inspection for surface tension that may result in dye blotchiness. Fat and oil is replenished with Fatliquor-5.0, after Aniline-21 to rejuvenate the leather for the desired suppleness when dry. Wax Effect-8.6 rejuvenates the structural wax pull-up effect, and coagulates a cloudy waxy coating on the surface to be heat activated, into the characteristic glossy sheen. Protector-D/D+ enhances a non-stick draggy-feel to shield against sticky soiling, besides healing and concealing lightening scuff and abrasion marks. Note that the mentioned product suffix number denotes its pH value in this holistic leather-safe aniline wax pull-up leathers topcoat and dyestuff refinishing system.


    Stripping Existing Topcoat:
    1- Cover and tape off frames and trims.
    2- Mist sprays Stripper-2.3, Eraser-4 scrub and towel extract to the entire section for an even appearance.

    1- Shake Degreaser-2.2 to gel prior to use.
    2- Transfer to Eraser-4, agitate to saturate body oil, grease and sweat contact areas, feather out to the entire section and let dwell 10 to 30 minutes.
    3- Towel extracts suspended soiling before it dries until it shows clean.
    4- Spray Acidifier-2.0, towel extract until it shows clean to a healthy squeak.

    1- Spray Hydrator-3.3 saturating the stain area and feather out for an even appearance.
    2- Covering body stain areas with tissue paper without airspace allows wick up soiling particulates to be trapped by the paper instead of remaining on the leather surface as it dries.
    3- Check for satisfaction when dry with Eraser-4 of wick up soiling prior to dyestuff refinishing.

    Dry Preparation:
    1- Erase wick-up residue with Eraser-4. A little stretching also lightens up appearance.

    Pre Dyeing Inspection:
    Surfactant-3.6 is mist spray to check for surface tension. Any blotchiness is work out to an even appearance especially on those body contact areas. Surface may be left to natural dry prior to Aniline-21 application.

    1- Apply Aniline-21 with airbrushing to produce professional result by controlling even dispersion over the surface.
    2- Light mist spray is preferred and let dry in between coats to observed color build up effect.
    Note: just like water coloring, the color intensity builds up by layers.

    Post Dyeing Inspection:
    1- Hydrator-3.3 is saturated into the leather structure to redistribute the Aniline-21 and any excess is towel extracted.
    2- Dwelling up to 72 hours allows sufficient water movement within the leather structure. The moisture level has to be kept high with a little moisture oozing out when pressing with fingers to be effective. (Read . . .

    Fatliquoring Pre-conditioning:
    1- Keeping the Hydrator-3.3 at a high level for up to 72 hours acts as a pre-conditioner to fatliquoring as well, as it helps to charge the leather protein fiber ionic more positive (+ve) for effective hydrogen bonding of the ionic negative (-ve) Fatliquor-5.0

    Fat and Oil Replenishing:
    1- Spray Fatliquor-5.0 and redistribute with foam brush until saturation.
    2- Repeat application each time water contents evaporate until fully saturated.
    3- Drive remaining surface remnants free of milky fat and oil until it turns clear with Hydrator-3.3.
    4- Allow natural drying for extra softness.
    (Leather Approximate Quantity or Percentage of Fatliquor:
    The quantities of fatliquor (fat and oil) contents retained in the leather after an universal tannery fatliquoring process may varies up from 14% to 16% depending on the leather types and it usage. This percentage drops as the fat and oil content diminishes or leaches through ageing, water, heat or chemical overexposure. Leather rejuvenating or fatliquor replenishing is base on weight of the leather in relation to the percentage of remaining fatliquor. A simple calculation of percentage of fatliquor topping up requirement would be as follows: If the weight of the leather in question is 100gm and fatliquor (fat and oil) content meter reading is less than 1%. By applying 80gm of Fatliquor-5.0 to it will deliver an end result incremental of 13.3% fatliquor when dry as the 66.6% water contents evaporates. In the leather rejuvenating Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system, Hydrator-3.3 plays an important role by relaxing, opening up the inter-fibrillary spaces, facilitating and redistributing colloidal water movement, protonating and doing all the pre-conditioning work prior to fatliquoring including cleaning up any excess surface remnants to have a sticky-free surface. In practice with severe dryness the ratio for Hydrator-3.3 is 2 to 1 of Fatliquor-5.0. It works out to be approximately 160gm of Hydrator-3.3 plus 80gm of Fatliquor-5.0 to replenish a 100gm dry leather from less than 1% back to the original tannery up from 14% to 16% fatliquor content. In every bottle of Fatliquor-5.0 by weight content is comprises of 16.66% ionic negative (-ve) charged fat and oil, and 83.33% of water, the water content that encased the fat and oil molecule in an emulsion suspension when hydrogen bond with the ionic positive (+ve) leather protein fiber will break free and discharged clear from the leather structure to the surface.

    Wax Effect Rejuvenating:
    1- Shake well, spray Wax Effect-8.6 evenly with brush or towel, spread to saturate deep, with a little moisture oozing out, when press with fingers, and leave natural dry, until wax crystal forms, on the surface, to be heat activated, with heat blower, or hair dryer to a glossy sheen.

    Topcoat Refinishing:
    1- Shake AnilineTop-76G well and apply by brushing, padding or airbrushing for professional result.
    2- Use Towel-5 to even out drips and streaks.
    3- Speed dries between coats with help of hair dryer.
    4- 2000-grit sanding may applies to improve touch and appearance.

    When tackiness is experience after drying a 10% Crosslinker-25 is recommended to be added into the AnilineTop-76G for reapplication.

    Rub-Resistant Protection:
    1. Mist sprays Protector-D/D+ redistribute with Towel-5, and ready for use when dry.

    How long does it take for the wax effect to dry before you use the blow dryer. The surface looks a bit gray and feels dry to the touch after about 6 hours drying. Will it become more glossy once I apply the Aniline Top 76G?

    >>> How long does it take for the wax effect to dry before you use the blow dryer.

    It will depends how deep and amount is saturated , air movement and the atmospheric humidity. However, the wax crystalline eventually will appears like a chalky appearance, and the heavy will produce better pull-up effective within the leather structure and also impart the waxy gloss. A heat blower will do the job otherwise a hot hair dryer need to melt the deposited water surface.

    >>> The surface looks a bit gray and feels dry to the touch after about 6 hours drying.

    Need to determine by a close look what is the cause to rectify accordingly - picture will help.

    >>> Will it become more glossy once I apply the Aniline Top 76G?

    Yes the gloss will be magnified many times.
