Leather Degreaser 2.2 is used for degreasing, cleaning, and pH balancing accumulated unwanted soiling and other aging products. With a low pH value of 2.2, it helps to tighten up the deteriorating finishes too.
Leather Acidifier 2.0 works in sync with Degreaser 2.2 as a rinse to remove suspended soiling and also further acts as another round of pH balancing to reduce surface tackiness.
Bicast Topcoat 76G is used for topcoat refinishing with excellent toughness and flexibility.
Leather Crosslinker 25 is a high-solids hardener that binds some of the hydrophilic elements to prevent a sticky topcoat.
Protector B is a protective, non-stick solution with a soft, buttery texture that helps reduce sticky surface contact.
Tools:
Leather Eraser 4 is used to remove foreign material with greater traction power during the cleaning process.
Leather Brush 1 for all general cleaning.
Foam Brush 2 for application, a varnishing brush will produce a streak-free result.
Towel 5 for general application and can be doubled up for padding.
Sand2000 is for fine sanding in between coats as necessary.

1: What is Bicast Leather?
Bicast or Bycast is split leather with a layer of polyurethane applied to the surface and then embossed.
Bicast, as a result, is a slightly stiffer product that is cheaper than top-grain leather, but it has a much more consistent texture and is easier to clean and maintain.
Bicast furniture exhibits none of the characteristics associated with aniline wax pull-up leather.
With constant use, bicast leather may develop delamination and peel in the often-flexed area.
The seating cushion may also develop splits at weak points.
Exposure to inert gases, body oils, grease, and sweat, as well as body heat, can cause stickiness on urethane finishes.
2: What is a Bicast Leather Sticky Problem?
The problem with Bicast leather is often described by owners as the finish becoming dull on the seating areas, and any material that comes in contact with it sticking to it.
Bicast finishes feel a bit rubbery, but after five minutes of sitting, clothing becomes stuck to it.
The area that experiences tackiness also exhibits roughness when touched.
When sitting down or standing up, there is a sound of tape being pulled, and a pattern from jeans can be seen on the couch.
If these experiences sound familiar, then Kit B7 or an upsized content with Kit B7 Plus is the answer.

4: How to work with Degreaser 2.2 and Acidifier 2.0 systems?
4.1 Degreaser 2.2 has to be shaken to gel before use.
4.2 Degreaser 2.2 is transferred to the horsehair Leather Brush 1 or Eraser 4 before working deeply with brush agitation and eraser traction action to remove accumulated soiling.
4.3 Suspended soiling is extracted using a lint-free towel and the folding sides are changed until the towel appears clean.
4.4 Acidifier 2.0 is sprayed and worked by brushing and erasing, then towel extracted until folding sides are clean. Check for reduced tackiness otherwise respray and let the acidifier pH balance any remaining alkaline residue. Repeat as necessary for improved tackiness. Let it dry or blow dry with a hair dryer.
4.5 Rough surfaces are smoothed with appropriate 1000/2000 grit sandpaper and rinsed clean, free of dust and lint, with a towel.
4.6 Let it dry, or use a hair dryer to blow it dry. It is now ready for top coating.
5: How to work with the Bicast Top 76G and Crosslinker 25 system?
5.1 Bicast Top 76G is swirled or shaked well before slowly adding to the Crosslinker 25 and mixed thoroughly before adding more. Continue to swirl the mixture for 5 minutes. Allow the mixture to react for a minimum of 30 minutes before using. For best results premix cross-linker/coating 2-4 hours before applying. This will ensure optimum catalyst reaction time and flow/leveling performance of the coating during applications.
5.2 The mix is transferred to the foam brush and applied in a circular motion to avoid streaks on the prepared surface and let dry.
5.3 Subsequent coatings are applied until the desired gloss luster is achieved and let overnight dry for curing time.
5.4 The average of 3 coatings of Bicast Top 76G (4oz) covers approximately 40 square feet.
5.5 Allow at least 48 hours for a complete curing time before use.
6: How to work with Protector B?
6.1 Protector B is sprayed and spread with a folded lint-free towel, let dry, and ready to use. The leather scent version is Protector B Plus.
