Bicast leather becomes Sticky after Storage.

>>> Do you know which product I should purchase to remove the stickiness. I need only the product to remove the stickiness for my leather sofa topcoat

Products to remove the stickiness in a holistic system includes:
1) a restorative system,
2) a degreasing system,
3) a topcoat refinishing system and
4) a non-stick protection system

>>> I have the product for cleaning the leather

The products you have used for cleaning may have removed the soiling to your satisfaction but the pH value have to been brought low as pH value above 5 swells the coatings and pH below 3 contracts the swelling from further deterioration. Thus a restorative system with ‘CleanPro-1.5 > Acidifier-2.0’ is recommended.

>>> and the product to make it softer.

Any conditioner on the surface need to be stripped as it will interfere with the new topcoat with poor adhesion. Thus a degreasing system with ‘Degreaser-2.2 > Acidifier-2.0’ is recommended.

>>> Which product do you think I need outside of these two.

These two products used have to be fully neutralized or pH balanced and any surface residue even from the conditioner need to be stripped to the original urethane finish before a new urethane topcoat is recommended.

Recommended topcoat is ‘BicastTop-76G + Crosslinker-25’ system for a permanent sticky solution.

Recommended non-stick protection is with Protector-B+.

I have not heard any more stickiness from those who have used this recommended holistic system.

Leather Doctor® Kit-B7+ is an upsize version of Kit-B7 with double the cleaning coverage and topcoat refinishing formulated to restore the common sticky problem associated with Bicast and Simulated urethane finished leathers. Owner often describes the sticky problem as follows: The finish has 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. New product introduced is the CleanPro-1.5 (pH 1.5), which takes care of the general non-body contact areas, follows with Acidifier-2.0 as rinse. This restorative cleaning both removes foreign contamination and reduces stickiness at the same time. Stripping the surface contamination including conditioners and protectors to the original finishes is done by Degreaser-2.2 with the help of Eraser-4 for better traction to removed surface materials. Suspended soiling is towel extracted and rinse with Acidifier-2.0. Sanding helps reduce surface roughness if any and the dust free surface is ready to receive a new topcoat. A 10% Crosslinker-25 is added to the BicastTop-76G prior to refinishing for extra finish strength from stickiness. The application is dry between coatings until matching up to the original luster level. Protector-B (scentless) imparts a non-stick buttery-feel against sticky soiling and rub-resistant against friction-wear. The optional Protector-B+ extra featurefurther diffuses a leather scent enhancing the leather more sensuously and luxuriously. This starter kit is design as a holistic system, with 3 coatings BicastTop-76G + Crosslinker-25 covers approximately 80 square feet. Optional adds-on and refills are available as individual bottles.

Instruction

Wet Preparation: 1) Protect floor with plastic covering from overspray and drips prior to restorative cleaning and stripping accumulated soiling. 2) CleanPro-1.5 is spray and work with horsehair Brush-1 and Eraser-4 and towel extracted until towel shows clean. 3) Use the Eraser-4 sponge side for normal cleaning and the crepe side for extra scrub from embedded materials. 4) Degreaser-2.2 is used in combination on the body contact oil and grease areas especially to the headrest and the hand-rest. 5) Shake the Degreaser-2.2 from separation to gel prior to use. 6) Apply by brushing with Brush-1 and/or scrubbing with Eraser-4 to remove surface soiling. 7) Suspended soiling is extracted with a lint-free towel or cleaning sponge until towel shows clean. 8) Spray Acidifier-2.0, agitate with Brush-1 and Eraser-4 and extract until towel shows clean again. 9) Inspect for reduced tackiness, otherwise spray soaks Towel-T5 with Acidifier-2.0 and place until towel dries for inspection. 10) When dry, sand surface roughness and ensure free of foreign material. 11) Surface is ready for topcoat application when smooth and free of residues.

Refinishing:
1) Empty the Crosslinker-25 25gm bottle (about 10%) into the BicastTop-76G 220gm bottle and swirl very well. 2) Once the topcoat is cross-linked, it is best to used within 8 hours, otherwise it will be cured hard and be useless. 3) Apply by BristleBrush-3” lightly to avoid streaks or finer soft varnishing brushes for streaks free result or airbrushing for professional result. 4) Dabbing with bristle brush reduces streaks as well as using a roller sponge. 5) Steaks are corrected by fine sanding when dry. 6) Use a hair dryer for speed drying in-between coats to satisfaction. 7) Let it overnight cure before non-stick Protector-B application.

Non-Stick Protection:
1) Protector-B is applied evenly with either PolyBrush-3” or paper towel and is ready for use when dry. 2) For routine application, a paper towel is recommended to simultaneous soiling extraction.
