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.
