    Default is this bicast or pigmented? and what is recommended to improve...

    Hi,

    I came across this forum in my search for answers about two 2-seater sofas I'm attempting to restore.

    I thought it was bicast due to being so water-proof but then read that bicast didn't appear on sofas until after these were bought (around 15 years ago).

    I attach a pic of one of the sofas in it's grubby untouched state called uncleaned_sofa.JPG

    Also a close up of a small section of the leather from underneath and inside the sofa where the sun or people have not touched it for 15 years called original_leather.JPG

    I started with one of the sofas and so far have used DrLeather cleaner a couple of times (which made it cleaner but very matt see clean_1a.JPG) followed by rubbing alcohol which again made it even cleaner but even more matt and rubbery - see clean_2.JPG.

    After reading some threads on this forum I am inclined to think they are made of bicast leather. I also attach an image of a small tear on one cushion in case this helps identification - small_tear.JPG.

    So, is this bicast?

    Is the recommendation to use Kit B7?

    If so, is one kit of this big enough for a 2-seater (160cm wide).

    Or is the sofa beyond help - which would be a shame as the frame is still very strong after all these years.

    >>> So, is this bicast?

    From appearance it is typical Bicast


    >>> Is the recommendation to use Kit B7?

    I believe you want the gloss finish back then the BicastTop-76G will bring back the gloss. If tackiness is the problem add the Crosslinker-25 to the Topcoat. You may start with Kit-B7+ and refills are available as individual bottles.

    The tear repairs is done with Bond-3D and Patch-4S.

    Color refinishing thereafter is with http://www.leatherdoctor.com/kit-b8-...ing-color-kit/

    Thanks Roger,

    How does bicastpro-1.5 fit in this scenario?

    http://www.leatherdoctor.com/bicastpro-1-5/

    is it of use? If so, would I use the bicastpro then acidifier then the degreaser and then acidifier again?

    BicastPro-1.5 > Acidifier-2.0 system is meant for the non body contact areas, like the back and side of the sofa.

    Degreaser-2.2 > Acidifier-2.0 system is for the body oil, grease and sweat contact areas.
