    Default 10 years old Italsofa sticky problem.

    Hi Roger, the sofas are about 10 years old, the name brand is Italsofa, and we noticed the stickiness at about 9months of ownership. We bought the sofa from Sandys furniture store. We have received the Leather Doctor Kit-B7 Bicast Leather Sticky kit and would like to get started on the treatment. I do have some concerns on the amount of product in the kit and hope it is enough to do the job.

    The maximum stretch for the 70ml bottles of BicastTop-76G plus the Crosslinker-25 is only about 70 square feet for one thin coat. A thicker coating may reduce the coverage to half and additional coating will further reduce to half again.

    Suggestion is to start with the loveseat and see how far it can go.

    Refills are available as individual bottles - http://www.leatherdoctor.com/bicasttop-76g/

    Foreign soiling including the lint is first removed by Degreaser-2.2 with help of Eraser-4 and thereafter rinse free with Acidifier-2.0 as the wet preparation for topcoat refinishing.

    When dry the surface is sand with sandpaper folded over the Eraser-4 to remove some deteriorated topcoat as the dry preparation for topcoat refinishing.

    The 7ml bottle is empty into the 120ml bottle swirl and mix thoroughly and is ready to apply with the foam brush.
    A hair dryer facilitate the fast drying of the topcoat and a second application may even out application.

    Note: The leather is held apart from contact otherwise they becomes stick together, otherwise wax paper is place in between contacts. The cure time may takes 24hrs.

    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.

    Instruction

    Wet Preparation:
    1. Protect floor with plastic covering from overspray and drips prior to stripping accumulated soiling.
    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.

    Refinishing:
    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.

    Non-Stick Protection:
    1. Protector-B+ is applied evenly with either foam brush or paper towel and is ready for use when dry.
    2. For routine application, a paper towel is recommended to simultaneously extract soiling.
