Bicast Leather Sticky Topcoat Refinishing - Kit-B7 by Leather Doctor is an innovative system formulated 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 a towel extracted and rinse with Acidifier-2.0. 2000-grit sandpaper or coarser to match is used to smooth rough surfaces. A 10% Crosslinker-25 is mixed to the BicastTop-76G for extra finish strength from stickiness. Protector-B (scentless) imparts a non-stick buttery-feel against sticky soiling; a rub-resistant against friction wear (optional Protector-B+ leather scented version diffuses a leather scent that enhances leather sensuous and luxuriously). This kit comes in concentrates to save on shipping thus Acidifier-2.0 and Protector-B have to be cut/mix and fills with distilled water accordingly prior to use. This starter kit is formulated as a holistic system; optional adds-on and refills are available as individual bottles - see the link to individual products below . . . The average of 3 coatings BicastTop-76G (120ml) covers approximately 40 square feet.
Step-1 Preparation: 1- Protect floor with plastic covering from over-spray and drips prior to restorative cleaning and stripping accumulated soiling. 2- Degreaser-2.2 is used in combination with the body contact oil and grease areas especially to the headrest and the hand-rest. 3- Shake the Degreaser-2.2 from separation to gel prior to use. 4- Apply by brushing with Brush-1 and/or scrubbing with Eraser-4 to remove surface soiling. 5- Suspended soiling is extracted with a lint-free towel or cleaning sponge until the towel shows clean. 6- Spray Acidifier-2.0, agitate with Brush-1 and Eraser-4 and extract until towel shows clean again. 7- Inspect for reduced tackiness, otherwise, spray soaks Towel-T5 with Acidifier-2.0 and place until towel dries for inspection. 8- When dry, sand surface roughness and ensure free of foreign material. 9- Surface is ready for topcoat application when smooth and free of residues.
Dry Preparation Prior to Topcoat Refinishing - Note: Ensure that all deteriorated topcoat is thoroughly sand off with an oscillating sander using sanding grit, 800, 1000 to 1200. Inspection is done with our slightly damp fingers to detect any such stickiness prior to topcoat refinishing commencing from Step-2.
Step-2 Refinishing: 1- Empty the 120ml BicastTop-76G topcoat into the Crosslinker-25 12gm content in the 250ml bottle and swirl very well. 2- Once the topcoat is cross-linked, it is best to use within 8 hours, otherwise it will be cured and be useless. 3- Apply by foamBrush-3 lightly to avoid streaks or finer soft varnishing brushes for a streaks free result or airbrushing for a professional result. 4- Dabbing reduces streaks and using a roller sponge is another option. 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.
Note: Test for satisfaction otherwise post your pictures and problem to http://www.leathercleaningrestorationforum.com/forum/forumdisplay.php?55-Upholstery-Bicast-Faux-Vinyl-Simulated-Leather for consultation prior to Step-3.
Step-3 Protection: 1- Protector-B is applied evenly with either foamBrush-3 or Towel-5 and is ready for use when dry. 2- For routine application, a lint-free towel is recommended for simultaneous soiling extraction.
