We have a 10-yr old couch that has become very tacky/sticky...
It is only on the seat cushions.
The armrests and back cushions seem to be holding up quite well.
Here are a few pictures.

Leather finishes becomes sticky / tacky is one very common problem associated with Bicast leathers.
The close-up pictures show the finish topcoat loses its clarity.
It also show remnants of clothing material that becomes stick to it like a clear carton sealing tape slowly loses its clarity with accumulated soiling from lint’s and fabric material.
Foreign soiling accumulation logically has to be removes prior to applying a fresh new topcoat and the sequence of refinishing the deteriorated topcoat should be as follows:
1.] Stripping Accumulated Soiling:
Use Degreaser-2.2 with help of Eraser-4 traction scrub to get rid of accumulated lint’s and clothing soiling.
Rinsing with Acidifier-2.0
2.] Resurface Existing Topcoat:
Use 2000grit fine sanding paper to reduce deteriorated topcoat distortion in combination during wet stripping or dry prep prior to topcoat application.
3.] Color Refinishing (as necessary):
When color loss is revealed during this stage, it is recommended to restore the color accordingly prior to topcoat refinishing it.
4.] Refinishing
1. Crosslinker-25 10% is added into the BicastTop-76G to control existing stickiness. Once the topcoat is cross-linked, it is best to used within 8 hours, otherwise it gels.
2. Apply by foam brush very lightly to avoid streaks with hair dryer speed drying.
4.] Non-Stick Protection
1. Protector-B+ is applied to the leather with either foam brush or paper towel for a non-stick experience.
