    Default Ikea Kivik – bycast/bicast leather – topcoat bubbling and peeling!

    I have an IKEA KIVIK series leather sofa.
    I found it most likely is bycast leather because the top coat bubbling up and peeling off within 2 years time.
    The peels feel like polyurethane to me but black color.
    The bald spots feel like leather though.
    What product should I use to fix it?

    >>> I found it most likely is bycast leather because the top coat bubbling up and peeling off within 2 years time.

    There are two color layers to this leather.
    The opaque pigment color layer remains while the transparent layer is peeling off.



    >>> The peels feel like polyurethane to me but black color.

    This layer is replaced with Bicast-76 (black) while the remaining is removed.
    To have it more durable Adhesor-73 is recommended prior to Bicast-76.



    >>> The bald spots feel like leather though.


    This is the opaque layer that block off the leather crust color below.
    Degreasing is recommended to removed accumulated soiling with Degreaser-2.2 > Rinse-3.0 system prior to Adhesor-73.



    >>> What product should I use to fix it?

    The sequence of products is as follows:
    1 – Remaining peeling layers may be removed with a combination with Eraser-4 > Stripper-2.3 > Sanding to feather out edges.
    2 – Degreaser-2.2 > Rinse-3.0 to remove surface contamination.
    3 – An option to rejuvenate (Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system) the below surface leather structure where micro crazing develops and the leather becomes absorbent (this effort prevents leather stiffness that leads to creases and cracking).
    4 – Surface is dry prepared with fine sanding etching the primary coating without removing it.
    5 – Adhesor-73 treatment by rubbing into the primary coating and remaining removed from extra build-up.
    6 – Bicast-76 application to build up beauty of depth.
    7 – BicastTop-76G to seal the leather with a gloss luster.
    8 – Protector-B+ leather scented or scentless version ‘B’ to reduce friction rubs and prolong the wear to the finishes.

    Leather Doctorฎ Kit B8.cl, Bicast leather color refinishing kit is design for a holistic restoration approach to not only the finishes but also rejuvenating the leather crust for suppleness. Most of these repairs are for abrading damages into the leather split-suede crust.
    Most of these exposed areas may be contaminated with foreign soiling that includes conditioners, protectors, body oil, grease and sweat or alkaline overexposure from non leather-safe cleaners.
    A comprehensive repair for a long-term lasting solution will require a holistic approach to deal with both the exposed leather split-suede for structural integrity and surface finishes for aesthetic.
    A leather-safe restoration system begins with removing foreign contamination from the penetrated leather structure and from the surface with the proven Degreaser-2.2 follows with Rinse-3.0 to a healthy squeaky feel.
    A pH in-balance leather structure with alkalinity overexposure will manifest as tackiness, stickiness or in extreme cases sliminess. The ionic strength of such denaturing leather will need to be strengthen by protonating its ionic positive (+ve) with the help of Acidifier-2.0 until the leather is revert back to a healthy pH chemistry integrity.
    Penetrated soiling may be further moves with the help of Hydrator-3.3 by successive wicking process with optional reverse transfer technique and erase off with Eraser-4 for a satisfactorily inspection.
    Leather rejuvenating system for softness and strength is accomplishes with Hydrator-3.3 follows with Fatliquor-5.0.
    Surface uneven absorption is seals with Adhesor-73 to smooth out the suede and restore a skin to reduce the need for color over-coating thus increase its flexibility and stretchability from coating premature cracking.
    With Adhesor-73 as a base for adhesion promotion as well, it is ready for color coating with Bicast-32 an opaque pigment coloring to block out the unwanted based color. Bicast-76 is an aniline transparent color that gives the beauty of depth as the secondary coloring to simulate the appearance of aniline leather. And BicastTop-76 is a gloss topcoat that seals the coloring from bleeding, crocking and resistant to cleaning during the course of the leather useful life.
    Protector-B+ imparts a non-stick rub-resistant surface with a buttery feel, reduces noises that translate into less friction wear. As the leather surface is well lubricated it reduces compression when comes to heavy body contact thus reduces compressed creases, wrinkles thus prolong the useful life of the new finishes.
