    Default Restoration Hardware - Italian Brompton - Four Issues

    Hi Roger - Thanks for your email response today. My 4 issues with this furniture are - 1) Wide scratches/discoloration that I cannot rub out with a blow dryer. Image IMG_1749.jpg. 2) Deeper scratches and nicks. Image IMG_1750.jpg. 3) Coloration lighter in area that gets a lot of use. Image IMG_1751.jpg and 4) Sun damage with dryness and discoloration (no image). What do I use and in what order do I use your products to address these? Many thanks! Karen Gray Name:  IMG_1749.jpg

    >>> 1) Wide scratches/discoloration that I cannot rub out with a blow dryer. Image IMG_1749.jpg.

    The secondary conditioner (EffectWax-8.6) has diminished and dried up and needs replenishing or reconditioning back to normal.


    >>> 2) Deeper scratches and nicks. Image IMG_1750.jpg.

    These look like damages from nails, the dug-in flap is released and the flap is bonded with Bond-3D.(repairs may take on a darkening effect, just like all original repairs).


    >>> 3) Coloration lighter in area that gets a lot of use. Image IMG_1751.jpg

    Hydrator-3.3 may be used to redistribute dyestuff from the leather structure to the surface to a degree, and the primary conditioner with Fatliquor-5.0 helps to saturate the color intensity. Top coating with AnilineTop-76G also helps to magnify the color saturation.


    >>> and 4) Sun damage with dryness and discoloration (no image).

    When leather is exposed to heat such as sunlight, the UV lights bleaches the dyestuff and also dries up the primary and secondary conditioner, like Fatliquor-5.0 and EffectWax-8.6


    >>> What do I use and in what order do I use your products to address these?

    You will need Bond-3D, Bond-7A, and Kit-Aw6.tc

    Topcoat Refinishing Instruction:

    Degreasing:
    Removing of surface and penetrated grease is essential for a good bonding topcoat, just like any other refinishing work with the same principle. However, amphoteric protein leather material is especially pH sensitive, leather pH value of 3 to 5 should be maintained at all times during the degreasing process. Otherwise, high pH value bleeds the dyestuff and displaces it with blotchiness. High pH or alkalinity degreaser denatures the leather when the tanning agents leaches out resulting in tackiness and in the worst case sliminess. All degreasing will also dry up the original fatliquor and high pH value does more harm in drying up the leather. When degreasing existing cracks or dried leathers of fatliquor contents below 7% (read with a leather moisture meter or an equivalent wood moisture meter), it is recommended that hydrating it with Hydrator-3.3 prior to Fatliquor-5.0 first to top-up the fatliquor up to the original 14% prior to degreasing. This pre leather rejuvenating helps prevent over drying of the leather during the degreasing process that may accentuate or magnify existing cracks. Degreaser-2.2 is a dual-purpose formulation with a pH value of 2.2 to safely degreasing the leather surface and penetrated soiling, while charging the protein fiber ionic positive (+ve) below its iso electric-point or pH neutral or pI for an increase hydrogen bonding with the other ionic negative (-ve) leather constituents like the tanning agents, dyestuff and fatliquor.
    Instruction . . . 1- Apply Degreaser-2.2 after shaking it well, saturating sufficiently where apparent body contact soiling is evident and feather out to less body contact soiling areas. 2- Leather Eraser-4 is used for better traction without the risk of scratching the finishes. 3- Horsehair Brush-1 is used for stitching rows, welting, groves, creases and wrinkles, 4- Emulsified and suspended soiling is terry towel extracted until the towel shows clean.

    Rinsing:
    Rinsing the after working degreaser residue and suspended soiling is equally important for a residue free surface. Instruction . . . 1- Apply Rinse-3.0 agitate with Eraser-4 and Brush-1 and Terry towel extract until the towel shows clean. 2- Check for any surface tackiness and proceed with Acidifier-2.0.

    pH Balancing:
    Dye bleeding and or tackiness during the wet cleaning process manifested from unknown previous cleaning will need further pH balanced with Acidifier-2.0. With a pH 2.0 treatment the amphoteric leather protein fiber will increase its ionic positive (+ve) charge with the other ionic negative (-ve) leather constituents, restoring its pH chemistry integrity. Instruction . . . 1- Apply Acidifier-2.0, let it dwell and before it dries use a towel for extraction. 2- Towel is checked for signs of bleeding and surface check for tackiness. 3- Advanced treatment is allowed for a longer dwell with control plastic covering and inspect for satisfaction thereafter.

    Hydrating:
    Hydrating is introducing leather-safe surface-active agents to penetrate, relax and separate stick together fibers from locking up shrunk, creases and wrinkles stiffness. The leather may be dwell up to 72hrs while sealed with plastic cling wrapper to control evaporation until the leather is plumped or limped or softened to be stretched or manipulated crosswise to satisfaction. Instruction . . . 1- Apply Hydrator-3.3 for an even appearance and fully saturated to relax out the leather structure to satisfaction. 2- When leather is almost dry or about 25% total moisture content Fatliquor-5.0 replenishing commences.

    Fatliquoring:
    Fatliquoring is the process of replenishing original fatliquor content up to its formal tannery standard of 14% when dry. The fat and oil encased water molecule when ionic attracted by the protein leather fiber breaks free and evaporates leaving a breathing space for natural leather transpiration to take place for seating comfort. The fat plumps the leather for fullness when dry and the oil lubricates the millions of interconnecting like hinges for suppleness without cracking when the leather is flexed from use. Instruction . . . 1- Apply Fatliquor-5.0 and spread for an even appearance until fully saturated. 2- Before the leather is completely dry or about 25% moisture level more is applied until saturated again. 3- When dry to normal used the leather moisture content may be read with a leather moisture meter or an equivalent wood moisture meter to about 14%.
    Fatliquor-Free Surfacing: Surface Fatliquor-5.0 residue if any is removed with Hydrator-3.3 driving all surface residues below surface. Remember that Fatliquor-5.0 is a structural conditioner and not supposed to remain on the surface. Instruction . . . 1- Surface is sprayed with Hydrator-3.3 and works with horsehair Brush-1 until cloudy moisture if any turns clear.

    Wax Effect Replenishing:
    WaxEffect-8.6 is the secondary conditioner replenishing the leather structure to impart a below surface pull-up distress effect and an above crystalline wax deposit to be activated with a heat blower or hair dryer to a natural characteristically sheen. Instruction . . . 1- Apply WaxEffect-8.6 after a warm-up and shake-up. 2- Spray, spread and saturate with horsehair Brush-1 or other brush evenly producing a darkening effect. 3- Allow an 8 hour natural drying time or until cloudy crystalline is formed. 4- Activate the wax deposit with a heat blower or hot hair dryer to a natural gloss luster.

    Repairs:
    Bonding repairs with Bond-3D > Bond-7A.

    Topcoating:
    AnilineTop-21/76G is a water based polyurethane topcoat that is lightfast and non-yellowing. It has excellent flow and levelling properties, is recoatable and forms a flexible film coat that gives good performing results from friction wear. Instruction . . . 1- Application is either with foamBrush-3, Towel-5 or fine airbrushing to produce professional results. 2- Streaking or drippings if any is immediately corrected with a lint-free towel like Towel-5. 3- Sanding with a 2000grit in between coats improves the feel and touch of the finishes. 4- Gloss builds up with additional coatings.

    Protection:
    Protector-D is a non-film forming, non-stick scentless (optional Protector-D+ for a classic leather scent) protector that enhances a natural draggy-feel. It imparts a non-stick breathable barrier essentially to shield the detrimental effects of sticky soiling. Its natural draggy-feel protection increases the leather resistance to wet and dry rubs, thus reducing stretch, scuff and abrasion. It is also used as a scuff repairer, filling and concealing surface scuffs to improve appearance. Instruction . . . 1- Shake well, mist spray and spread evenly with a foam brush.
