How-To: Why would you need to re-fatliquor modern upholstery leathers?

Picture #1 shows modern upholstery leather that has rings, deep creases and wrinkles – a result of diminished original fatliquor.

Picture #2 shows close up symptoms of diminished fatliquor.

[Roger Koh]

Picture #3 shows relaxer3.3 (leather safe pH 3.3) application – to relax and plumps dried out or stiff leathers away the creases and wrinkles.

[Roger Koh]

Picture #4 shows dwell time for relaxer3.3 to redistribute the moisture throughout the entire leather structure with a plastic sheet (from 0.9mm to 1.5 mm structure thickness).
Conditions the leather below the leather iso-electric point to charge the protein fiber positively, ensuring it’s cationic (+).

Picture #5 shows anionic (-) fatliquoring after structure conditioning for effective hydrogen bonding with the cationic leather protein fiber.

Picture #6 shows another fatliquor5.0™ dwell-time with plastic sheet that ensure full absorption by the leather structure.

Picture #7 shows leather that has been plumed up three dimensionally without the creases and wrinkles.

You can do it too! I can help!

Is there a better way to correct these creases and wrinkles?

So this is showing getting rid of the excessive leather that has strthed and then all is needed is probably a bit of filling and recolourig and a finih applying?

Now, you are right on!
Keep it up!

Reason:
Without fatliquoring most refinishing will be futile as they will soon crease, wrinkles and cracks before the finish worn out!

Looks good Roger

Is the plastic wrap thickness critical - you mention .9 - 1.5mm

[Roger Koh]

Sorry, the thickness refers to the thickness of average upholstery leather.

Plastic wrap, use the thinnest cling wrapper you can find, and that way you want to smoothen it to the leather surface thereafter to reduce air bubbles for a tight contact.

Picture #1 shows wrapping with “Food Film Wrap” after fatliquoring
– to ensure fatliquor proper penetration into the leather structure for distribution of fatliquor within the leather inter-fibrillary structure.

Picture #2 shows fatliquoring to a “NC Napa semi-aniline” Hugo BOSS® fashion leather jacket.

Picture #3 shows hanging with a see-thru plastic garment bag to allow the fatliquor to continue its effect of hydrogen bonding.

Picture #4 shows fatliquoring Esprit® nubuck glove.

Picture #5 shows fatliquoring a wallet with a zip lock bag.

When you receive the kit, you can try it out with your favorite leather wallet first and see how you like it.

cleaner3.8™ > rinse3.0™ > fatliquor5.0™

Dwell in a plastic zip lock bag like picture #5 until the fatliquor turns clear.

The milky whites you see are the natural fats and oils.

Once the anionic (-) fatliquor5.0™ hydrogen bond takes place within the cationic (+) leather fibrils the water outer encasing breaks free and are exhausted as waste water.

Once the whites disappear, wrapped it with a paper towel and let it dry naturally.

All stains and foreign residue will be wicked through this paper towel.

To get it soft again just message, flex or stretch it.

Thereafter apply leatherScent’B™.

So you draw the soiling out first then condition to put back into shape?
