People Also Ask:
What is Fatliquor?
Fatliquor 5.0 conditioner is a micro-emulsion of fat, oil, and water for rejuvenating and restoring all leather, and suede types to impart their original suppleness, from dry rot and stiffness.
How Fatliquor Works?
Fatliquor 5.0 typically works in conjunction with a pre-conditioner like Hydrator 3.3 to relax and open up the fibrous leather structure, to ensure thorough and even absorption of fat and oil.
Why Fatliquor Works?
Fatliquor 5.0 fat content plumps the leather with fullness from easily collapsing into creases and wrinkles during stress or flex, while the oil content lubricates the fibers so that they slide over one another smoothly like millions of interconnecting hinges.
Fatliquor 5.0 helps to keep leather at its optimum physical performance and prevent premature aging.
Fatliquor 5.0 softens the leather when dry with stretchability, compressibility, and flexibility while enhancing its rip tensile strength greatly.
When Fatliquor Works?
Fatliquor 5.0 on application, the water-encased molecule breaks free when ionic attraction takes place between the fat and oil with the leather protein fiber. The excess free water content wicks out leaving a breathing space behind for leather's natural transpiration.
What is the Purpose of using Fatliquor?
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. Unlike other stuffing conditioning oil that just fills up the breathing pores.
What is the Purpose of Fatliquor?
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.
What is the original leather percentage of fatliquor contents from the tannery?
Fatliquor content retained after a universal tannery when dries vary from 14% to 16% depending on the leather type and its usage.
How fatliquor content of fat and oil diminish?
Fatliquor percentage drops as the fat and oil content diminish through aging and heat or leached from water or chemical overexposure.
How to determine the percentage of fatliquor required by the leather?
Fatliquor content required by the leather is based on the weight of the leather in relation to the percentage of remaining fat-liquor.
How to calculate the percentage of fatliquor required?
Fatliquor requirement is simply calculated by the difference in percentage. If the weight of the leather is 100gm and the leather moisture reading is less than 1%. Applying 80gm of Fatliquor-5.0 will deliver an end result incremental of 13.3% fatliquor when dry as the 66.6% water content evaporates.
Why is Hydrator 3.3 used as a preconditioner?
Hydrator 3.3 is used both as a pre-conditioner to relax, open up the inter-fibrillary spaces, and facilitate and redistribute colloidal water movement. Protonating and post-cleaning up any excess fatliquor surface remnants too.
What is the ratio of usage between Hydrator 3.3 and Fatliquor 5.0?
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 14% to 16% fatliquor content.
Fatliquor 5.0 by weight content is comprised of 16.66% ionic negative (-ve) charged fat and oil, encased in 83.33% of water.
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 will break free and discharge clear from the leather structure to the surface.
How to Use Fatliquor 5.0?
1* Concentrates in the bottle is to be cut/mix well with 5 parts warm distilled water before use.
2* Apply and redistribute with appropriate brushes or pads until the thickness of the leather or suede is saturated.
3* Repeat each time water contents evaporate leaving behind only the fat and oil content.
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.
5* Allow natural drying for extra softness.
6* Suppleness of leathers is further staked/massaged/flexed accordingly with a little wet back with Hydrator 3.3 until dry.
Always pre-condition the leather/nubuck/suede with Hydrator 3.3 to relax, soften, and open up the fiber structure prior to fatliquoring.
1* A fully fatliquor replenished leather maintains an average of 14% fat and oil content, while vegetable-tanned leather is more thirsty.
2* Insufficient fat-liquoring (fat and oil) content may remain stiff and may also suffer cracking from staking, massaging, or flexing.
3* When crispy dry, prior surface contamination/damages may darken as soiling particulates resurface.
5* Stretching the dark areas lightly will also lighten the appearance.

Product Reviews - Posted by Larry Bauman on 31st Jul 2017
This product revived my 40-year-old Sheepskin coat that cracked at the touch of it after applying another company's 'Restoration' product. That other product ruined my coat, and I was about to throw it away but took a chance on the Leather Doctor. 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. My coat is now as soft and supple as it was when I purchased it in 1975! Don't even take a chance on valuable leathers with other companies products, this one will amaze you with its results.
