People Also Ask:

What is Bicast Leather?

Bicast or Bycast leather 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 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.

Bicast with constant use, the often-flexed area may develop delamination and peeling; sitting cushion may developed split at the weak split veins and exposure to the inert gases, body oil, grease and sweat develops stickiness to the urethane finishes.

What is Bicast Leather Sticky Problem?

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

Bicast finishes feels a bit rubbery but after 5 minutes 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 B7 or an upsize content with Kit B7+ is the answer.

    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!
