    Default Bicast / Bycast Leather – Sticky Sofa!

    Bicast / Bycast Leather – Sticky Sofa!

    Hi, are you still in business?
    It's hard for me to tell where you are located, and if your products are still for sale.
    The forums for the Kit-B7 are dated many years ago.
    The web site shows a high price - don't know if there's any alternative shipping or something that lets me clean my sticky sofa.
    There are three pictures.
    How long does it stay sticky-free?
    It's pricey for me so I need to be sure it's really the right thing and about the result.
    Please let me know your advice.

    >>> How long does it stay sticky-free?

    When the sticky issue is performed accordingly to instruction it will be good for another lease of useful life.
    Since you mentioned that “the forums for the Kit-B7 are dated many years ago” and yet up to now there is no mention of reoccurrence issue has proves its effectiveness to solving leather sticky issue.

    Leather Doctor® Kit-B7, bicast leather sticky topcoat refinishing kit is an innovative system developed for bicast leather to restore finishes sticky problem. The sticky problem is often described from owners as follows. The finish gone dull on the seating areas and any material comes in contact sticks to it. The finishes feels a bit rubbery but after 5mins of sitting clothing were stuck to it. The location that suffers tackiness also reveals roughness to the touch. When sitting down and getting up, there is the sound of tape pulling and you can actually see a pattern on the couch from the jeans. If these experiences sound familiar then this kit is the answer. Stripping the surface contamination is done with Degreaser-2.2 and the help of Eraser-4 for better traction to removed surface materials. Suspended soiling is towel extracted and rinse with Acidifier-2.0. 2000-grit sandpaper is used to smoothen rough surface. A 10% Crosslinker-25 is added to the BicastTop-76G for extra finish strength from stickiness. Protector-B+ imparts a non-stick buttery-feel against sticky soiling; a rub-resistant against friction wear and diffuses a leather scent that enhances leather sensuous and luxuriously. This kit comes with reduced weight option to save on shipping thus the 250ml concentrate ratio for Hydrator-3.3 has to be cut or filled up with distilled water prior to use. This starter kit is design as a holistic system, optional adds-on and refills are available as individual bottles.

    2. Shake the Degreaser-2.2 to gel prior to use.
    3. Transfer to the Eraser-4 on the sponge side for normal cleaning and the crepe side for an extra scrub.
    4. Apply with agitation onto the leather finish to remove surface soiling.
    5. Suspended soiling is extracted with a lint-free towel or cleaning sponge until towel shows clean.
    6. Spray Acidifier-2.0, agitate with Eraser-4 and extract until towel shows clean again.
    7. When dry, sand surface roughness and ensure free of foreign material with 2000-grit sandpaper.
    8. Speed dry with hair dryer, free of residue and is ready for topcoat application.

    1. Crosslinker-25 10% is added into the BicastTop-76G to control existing stickiness. Empty the entire 7gm of Crosslinker-25 into the 70ml half filled bottle of BicastTop-76G and stir or swill it well. Once the topcoat is cross-linked, it is best to used within 8 hours, otherwise it will be cured hard and be useless.
    2. Apply by foam brush lightly to avoid streaks or use soft varnishing brushes for streaks free result or airbrushing for professional result.
    3. Steaks are corrected by fine 2000-grit sanding when dry.
    4. Use a hair dryer for speed drying in-between coats to satisfaction.
    5. Let it overnight cure before non-stick protection.
