Product Overview

Bicast Leather Sticky Topcoat Refinishing Kit B7 by Leather Doctor is for restoring the common sticky issue on Bicast and simulated leather urethane finishes.

This Kit B7 product system has been handpicked to perform a Bicast refinishing solution to address the issue of a sticky topcoat.

A holistic system to solve Bicast's sticky problem involves these products, follow the link for more detailed readings.

Leather Degreaser 2.2 is used for degreasing, cleaning, and pH balancing accumulated unwanted soiling and other aging products.

Leather Acidifier 2.0 works in sync with Degreaser 2.2 as a rinse to remove suspended soiling and also acts as another round of pH balancing to reduce surface tackiness and tighten up deteriorating finishes. The concentrate in the bottle is mixed and filled with distilled water before use.

Bicast Gloss Topcoat 76G is used for topcoat refinishing with excellent toughness and flexibility.

Leather Crosslinker 25 is a high-solids hardener for Topcoat 76G that binds some hydrophilic elements to prevent a sticky topcoat. Topcoat 76G is added to the Crosslinker 25 bottle before use.

Leather Protector B is a non-stick protector with a soft, buttery texture that helps reduce sticky surface contact. The concentrate in the bottle is mixed and filled with distilled water before use.

Leather Eraser 4 with greater traction power during the degreasing process removes foreign material.

Leather Brush 1 for all general cleaning.

Foam Brush 2 for application, a varnishing brush will produce a streak-free result.

Towel 5 is for extracting suspended soiling and general application.

Sand2000 is for fine sanding in between coats as necessary.

6: How to work with Protector B?

1: What is Bicast Leather?

1.1: Bicast or Bycast is split leather with a layer of polyurethane applied to the surface and then embossed.

1.2: Bicast, as a result, is a slightly stiffer product that is cheaper than top-grain wax pull-up leather, but it has a much more consistent texture and is easier to clean and maintain.

1.3: Bicast furniture exhibits none of the characteristics associated with aniline wax pull-up leather.

1.4: With constant use, Bicast leather may develop delamination and peel in the often-flexed area.

1.5: The seating cushion may also develop splits at weak points.

1.6: 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?

2.1: Bicast leather sticky problem is often described by owners as the finish becoming dull on the seating areas, and any material that comes in contact sticks to it.

2.2: After five minutes of sitting the Bicast finishes feels a bit rubbery and the clothing becomes stuck.

2.3: The area that experiences tackiness also exhibits roughness when touched.

2.4: There is a sound of tape being pulled when sitting down or standing up, and a pattern from jeans can be seen on the couch.

2.5: If these experiences sound familiar, then Kit B7 or an upsized content with Kit B7 Plus is the answer.

3: How a 3-Step Process Solves the Bicast Sticky Issue?

3.1: Degreasing System by Degreaser 2.2 and Acidifier 2.0.

3.2: Refinishing System by Topcoat 76G and Crosslinker 25.

3.3: Protection System by Protector B.

4: How to work with Degreaser 2.2 and Acidifier 2.0 systems?

4.1: Degreaser 2.2 is worked to gel before use.

4.2: Degreaser 2.2 is swirled for about 5 minutes to get the coagulation building up from the bottom, when the coagulation reaches 75% level give it a vigorous shake to gel.

4.3: Degreaser 2.2 is transferred to the horsehair Brush 1 or Eraser 4 before working deeply to remove accumulated soiling.

4.4: Suspended soiling is extracted using a lint-free towel and the folding sides are changed until the towel shows clean.

4.5: Acidifier 2.0 is applied and worked by brushing and erasing, then towel extracted until folding sides are clean.

4.6: Tackiness is finger-tested, otherwise reapply, towel extracted, and reapply to allow dwelling until tackiness improved.

4.7: With satisfaction, let it dry or blow dry with a hair dryer.

4.8: Rough surfaces are smoothed with appropriate 1000/2000 grit sandpaper and rinsed clean, free of dust and lint, with a lint-free towel.

4.9: Let it dry, or use a hair dryer to blow it dry.

4.10: It is now ready for top coating.

5: How to work with the Topcoat 76G and Crosslinker 25 system?

5.1: Topcoat 76G is swirled well before slowly adding to the Crosslinker 25 and mixed thoroughly before adding more.

5.2: Continue to swirl the mixture for 3 minutes.

5.3: Allow the mixture to react for 30 minutes minimum before using.

5.4: For best results premix Crosslinker 25/Topcoat 76G for 2-4 hours before applying.

5.5: This will ensure optimum catalyst reaction time and flow/leveling performance of the coating during applications.

5.6: The mix is transferred to the foam brush and applied lightly to avoid streaks.

5.7: Let dry between coats with a hair dryer.

5.8: Subsequent coatings are applied until the desired gloss is achieved and left overnight for curing.

    Excellent Product--Highly Recommend

    Posted by Bicast Leather Sticky Topcoat Refinishing Kit on 29th Dec 2023

    I've been searching for several years for a solution to my leather couch that became (sticky). I found loads of information online about "sticky" leather due to "sweets" being spilled on it (not helpful). This is the first company I found that clearly explains the problem and offers a solution. After carefully going through the 3 step process, my couch looks practically new! Totally worth the money and time/effort. And the company was also very helpful in answering questions via email and got back to me right away. One note: be sure to have some distilled water as 2 of the products require this to be added.

    Great product, sofa is like new!

    Posted by Chris on 28th Jul 2015

    After about 8 years of use, my Natuzzi sofa became sticky on the seat cushions, to the point where it would transfer fibres from clothing onto the sofa. I tried contacting some local repair outfits and their response was that I would be better off buying a new sofa due to the nature of the bicast leather material. Their quotes for repair were around the $900 mark. Faced with a potentially unusable sofa, I did some research on the internet which led me to Leather Doctor and the Bicast Leather sticky topcoat kit. I placed the order and the kit arrived within days. I followed the preparation process, being careful to remove all of the fibres which were transferred to the sofa using degreaser and the 2000 grit sandpaper once the leather was dry. The acidifier made a huge difference in how the leather felt. No more stickiness! Finally, when the leather was once again dry, the urethane topcoat was applied. Be sure to apply this evenly to avoid streaking. It also darkens the colour of the leather slightly. Once the urethane was dry, the sofa looked nearly new, and the sticky problem solved. Final treatment was the the protector which gave a smooth feel to the leather, and also restores the original leather smell. One kit is enough for one 3-place sofa. I had a 3-place and a 2-place to refinish and the kit was only enough to do the seating surfaces and the fronts of both, but not the backs or the sides. Well worth the investment!
