    Default What to do with Sticky Bicast Leather?

    My couch and 2 armchairs are made of bicast leather and are very sticky. When you sit down and get up, there is the sound of tape, and you can actually see a pattern on the couch from the jeans; it is very sticky. I have wiped down and then dried the large sticky areas but it's sticky shortly thereafter. Also, it looks dull... and I'm wondering whether I should
    apply a product in order to make the bicast leather shiny, and whether this will eliminate the "stickiness" of the couch and chairs. Help - what leather product should I use?

    Tell us what liquids you have used so far on this Bicast?

    Most probably it’s due to Alkaline over exposure that need to be neutralized with an Acidifier-2.0 (pH 2.0).

    Alkaline will swell finishes that result in tackiness; acid will contracts them to a healthy squeak generally.

    To reduce stickiness; Leather Scent-B (buttery-feel) helps to impart a non-stick surface and produce a sheen more than the Leather Scent-D (draggy-feel) duller that helps to heal scuffs.

    A gloss topcoat can be used to recoat it; however the stickiness need to be rectified and surface stripped of soiling to the original finish prior applying it; otherwise it will be messier.


    So I think this would be the sequence of processes to follow:

    Acidifier-2.0 (to correct the stickiness) > Prep-7.7 (to strip foreign contamination down to the original finish) > Cleaner-3.8 (to remove the sticky residue) > Acidifier-2.0 (to pH balance to the acidic side for squeakiness) > Topcoat Pigment-64G (gloss) > Leather Scent-B or D.

    What do you think of the above recommendation?

    Good if you can post pictures, basically there are more than one type of Bicast; hopefully not dealing with the blistering heat sensitive types.

It imparts a non-stick barrier essentially to shield the detrimental effects of sticky soiling including the nasty ballpoint ink. And it does help to release those tenacious dye-transfer stains easily without resorting to unnecessary color refinishing. Its natural draggy-feel protection increases the leather resistance to wet and dry rubs, thus reduce stretch, scuff and abrasion. It is also used as a scuff repairer, filling and concealing surface scuffs to improve appearance. The drag produces an unforgettable familiar sound sweet to the ears when leather is rubbed.
