. . .
1: What is Fatliquor?
1.1: Fatliquor 5.0 conditioner is a micro-emulsion of fat, oil, and water for rejuvenating, restoring, and softening all types of leather and suede to impart their original suppleness and protect them from dry rotting and stiffness.
2: How does Fatliquor work?
2.1: Fatliquor 5.0 typically works in conjunction with a pre-conditioner like Hydrator 3.3 to relax and open up the fibrous leather structure, ensuring thorough and even absorption of fat and oil.
3: Why Does Fatliquor Work?
3.1: The fat content in Fatliquor 5.0 plumps up the leather, preventing it from easily collapsing into creases and wrinkles during stress or flex.
3.2: The oil content lubricates the fibers, allowing them to slide over one another smoothly like millions of interconnecting hinges.
3.3: Fatliquor 5.0 helps to keep leather at its optimum physical performance and prevent premature aging.
3.4: Fatliquor 5.0 softens the leather when dry, providing stretchability, compressibility, and flexibility while significantly increasing its rip tensile strength.
4: When Does Fatliquor Work?
4.1: When Fatliquor 5.0 is applied, the water-encased molecule breaks free when an ionic attraction occurs between the fat and oil with the leather fiber.
4.2: The excess free water content is wicked out, leaving breathing space for the natural transpiration of the leather.
5: What is the Purpose of using Fatliquor?
5.1: Fatliquor 5.0 carries an ionic negative (-ve) charge to hydrogen bond with the ionic positive (+ve) charge of the leather fibers, thus freeing up pores for better breathability.
5.2: Unlike other stuffing conditioning oils that just fill up the breathing pores.
6: What is the Purpose of Fatliquor?
6.1: Fatliquor 5.0 conditioning is for replenishing the original fat and oil that diminishes through sun bleaching, aging, heat, and alkaline over-exposure or cleaning.
7: What is the original percentage of leather fatliquor content from the tannery?
7.1: Fatliquor content retained after a universal tannery when dries varies by an average of 14% depending on the leather type and its usage.
8: How does the Fatliquor content of Fat and Oil Diminish?
8.1: Fatliquor percentage drops as the fat and oil content diminishes through aging and heat, or when it is leached out by water or chemical overexposure during cleaning.
9: How to determine the Percentage of Fatliquor required by the leather?
9.1: The Fatliquor content required by the leather is based on the weight of the leather to the percentage of remaining fat-liquor.
10: How to calculate the percentage of fatliquor required?
10.1: Fatliquor requirement is simply calculated by the weight difference in percentage.
10.2: If the weight of the leather is 100gm and the leather moisture reading is less than 1%.
10.3: Applying 80gm of Fatliquor 5.0 will deliver a result incremental of 13.3% fatliquor when dry as the 66.6% water content evaporates.
11: Why is Hydrator 3.3 used before Fatliquor 5.0?
11.1: Hydrator 3.3 is used both as a hydrator to relax, open up the inter-fibrillary spaces, and facilitate and redistribute colloidal water movement.
11.2: Besides, protonating it is use to post-clean fatliquor surface remnants.
12: What is the ratio of usage between Hydrator 3.3 and Fatliquor 5.0?
12.1: Hydrator 3.3 to Fatliquor 5.0 ratio practice is 2 to 1, and it works out to be approximately 160gm of Hydrator 3.3 plus 80gm of Fatliquor 5.0 to replenish 100gm dry leather, from less than 1% back to the original tannery up from an average of 14% fatliquor content.
12.2: Fatliquor 5.0 by weight content is comprised of 16.66% ionic negative (-ve) charged fat and oil, encased in 83.33% of water.
12.3: Fatliquor water content that encased the fat and oil molecule in an emulsion suspension when hydrogen bonds with the ionic positive (+ve) leather protein fiber break free and discharge clear from the leather structure to the surface.
13: How to Use Fatliquor 5.0?
13.1: Concentrate in the bottle is to be cut/mixed well with 5 parts warm distilled water before use.
13.2: Apply and redistribute with appropriate brushes or pads until the thickness of the leather or suede is saturated.
13.3: Repeat each time water contents evaporate leaving behind only the fat and oil content.
13.4: Sticky residue is further driven into the leather structure or rinsed off until surface milky fat and oil turn clear with Hydrator 3.3.
13.5: Allow natural drying for extra softness.
13.6: Suppleness of leathers is further staked/massaged/flexed accordingly with a little wet back with Hydrator 3.3 until dry.
14: Tips:
14.1: Always pre-condition the leather/nubuck/suede with Hydrator 3.3 to relax, and open up the fiber structure before Fatliquor 5.0.
14.2: A fully fatliquor replenished leather maintains an average of 14% fat and oil content, while vegetable-tanned leather is more thirsty.
14.3: Insufficient fat-liquoring (fat and oil) content may remain stiff and may also suffer cracking from staking, massaging, or flexing.
14.4: When crispy dry, prior surface contamination/damages may darken as soiling particulates resurface.
14.5: Removes surface soiling particulates with Eraser 4 for all leathers including nubuck and Eraser 5 for suede.
14.6: Stretching the dark areas lightly will also lighten the appearance.

15.1: The Lazarus Effect https://leatherdoctor.com/sheepskin-care-kit-sr3/#product-reviews
15.2: This product revived my 40-year-old Sheepskin coat that cracked at the touch of it after applying another company's 'Restoration' product.
15.3: That other product ruined my coat, and I was about to throw it away but took a chance on the Leather Doctor.
15.4: After applying Hydrator 3.3, I saw an immediate change. I then continued with the Fatliquor 5.0 and was shocked to see the change.
15.5: My coat is now as soft and supple as it was when I purchased it in 1975!
15.6:Don't even take a chance on valuable leathers with other companies products, this one will amaze you with its results.
16: Your opinions and insights are precious and will help us to improve our writing to solve your leather problem more efficiently.
