Product Description
LeatherFatliquor-5.0 conditioner by Leather Doctor is an anionic negative (-ve) charged micro-emulsion of fat, oil, and water for rejuvenating all leather, and suede types. Leather fat-liquor conditioner is typically used in conjunction after LeatherHydrator-3.3 to relax and open up the fibrous leather structure. Leather fat-liquor conditioner softens the leather when dry with stretch-ability, compress-ability, and flex-ability while enhancing its rip tensile strength greatly. Fat-liquor conditioner is for replenishing the original fat and oil that diminishes through sun bleaching, aging, heat, and alkaline overexposure or cleaning. 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 natural transpiration. The fat plumps the leather with fullness from easily collapsing into creases and wrinkles during stress or flex, while the oil lubricates the fibers so that they slide over one another smoothly like millions of inter-connecting hinges. This helps to keep leather at its optimum physical performance and prevent premature aging. This universal LeatherFatliquor-5.0 is for all leather types including pigmented, aniline, vachetta, nubuck, suede, hair-on-hide, and woolskin. Size options are available in 'Fill' and 'Con'. Fill is concentrate in the bottle to be cut/mix and fills with distilled water prior to use to save on shipping. The 'Con' is concentrated to be cut/mix with distilled water at a ratio of 1: 5 prior use.
Leather Approximate Quantity or Percentage of Fat-liquor:
The quantities of fat-liquor (fat and oil) contents retained in the leather after a universal tannery fat-liquoring process may vary up from 14% to 16% depending on the leather types and its usage. This percentage drops as the fat and oil content diminish or leaches through aging, water, heat, or chemical overexposure. Leather rejuvenating or fat-liquor replenishing is base on the weight of the leather in relation to the percentage of remaining fat-liquor. A simple calculation of the percentage of fat-liquor topping up requirement would be as follows: If the weight of the leather in question is 100gm and fat-liquor (fat and oil) content meter reading is less than 1%. By applying 80gm of Fatliquor-5.0 to it will deliver an end result incremental of 13.3% fat-liquor when dry as the 66.6% water contents evaporate. In the leather rejuvenating Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system, Hydrator-3.3 plays an important role by relaxing, opening up the inter-fibrillary spaces, facilitating and redistributing colloidal water movement, protonating and doing all the pre-conditioning work prior to fat-liquoring including cleaning up any excess surface remnants to have a sticky-free surface. In practice, with severe dryness, the ratio for LeatherHydrator-3.3 is 2 to 1 of LeatherFatliquor-5.0. It works out to be approximately 160gm of LeatherHydrator-3.3 plus 80gm of LeatherFatliquor-5.0 to replenish a 100gm dry leather from less than 1% back to the original tannery up from 14% to 16% fat-liquor content. In every bottle of LeatherFatliquor-5.0 by weight, content is comprises of 16.66% ionic negative (-ve) charged fat and oil, and 83.33% of water, the water content that encased the fat and oil molecule in an emulsion suspension when hydrogen bond with the ionic positive (+ve) leather protein fiber will break free and discharged clear from the leather structure to the surface.
Instruction:
1- Warm-up and shake well to a full emulsion for better penetration.
2- Apply LeatherFatliquor-5.0 conditioner and redistribute with foam brush until saturation.
3- Repeat applications each time water contents evaporate until fully saturated.
4- Drive remaining surface remnants free of milky fat and oil until it turns clear with LeatherHydrator-3.3.
5- Allow natural drying for extra softness.
6- Suppleness of leathers is further stake or massage or flex accordingly with a little wet back with LeatherHydrator-3.3.
Caution:
Insufficient fat-liquoring (fat and oil) content may suffer cracking from staking, massaging or flexing.
Tips:
1 When crispy dry, prior surface contamination/damages may darken as soiling particulates resurface.
2 Removes soiling particulates with Eraser-4 for all leathers including nubuck and Eraser-5 for suede.
3 Stretching the darken areas lightly will also lighten the appearance.
Frequent Asked Questions:
>>> I finally got around to looking at the instructions to begin to apply my LeatherHydrator-3.3 > LeatherFatliquor-5.0 > LeatherHydrator-3.3 application. I must say, the instructions are quite extensive, a little confusing and I'm sure a lot that doesn't apply to my application. Again, I am trying to remove some wrinkles on a seat bolster in a car that is only 6 years old. So the leather I would imagine is the way it is from stress and not from age. Would you be able to tell me in simple, layman terms how you would recommend going about applying to achieve the results I am looking for? It would be greatly appreciated.
With the LeatherHydrator-3.3 > LeatherFatliquor-5.0 > LeatherHydrator-3.3 system you may start with:
1- Apply the LeatherHydrator-3.3 and use a horsehair brush or equivalent to remove surface soiling and extract with a white cotton terry towel until towel shows clean.
2- Apply LeatherHydrator-3.3 with the poly brush and let it absorbed into the leather structure - keep on apply as long as it gets soaks in.
3- Use a cling wrapper to control evaporation and leave it there up to 72hrs or shorter duration to soften up the leather structure. There should be a little moisture oozing out when press with fingers and thumb to have the hydration at its optimum level during this dwell time - may it long or short.
4- When the leather structure is limp and soft, the cling wrapper is removed and wick-up soiling is extracted with a towel until the towel shows clean.
5- While still damp, LeatherFatliquor-5.0 is applied with the same poly brush to be fully absorbed by the leather structure. In each application cycle, 83.33% of the fat-liquor water content needs to be evaporated. It is the fat and oil contents that are essential to supple up the leather, the fat plumps the leather, and the oil lubricates for softness. When the last application pools on the surface will indicate sufficient absorption and end the application.
6- The leather is left for slow natural drying and surface shine is removed with LeatherHydrator-3.3 until any milky residue is removed off the surface.
7- The seat can be used immediately by placing a towel over it.
8- It is also recommended that the seat be used from almost dry to dry to produce extra softness to the leather with strength.
>>> I have been keeping the zebra damp and applying fat-liquor with distilled water the last couple of days...it is pretty sodden and now looking white when I brush the fat-liquor solution over it which means to me that it is not sinking in anymore . . .
Before any application of LeatherFatliquor-5.0, the total existing combination of liquid content has to be reduced to about 25% through slow drying, thus have the capacity to received further LeatherFatliquor-5.0 in a repeated cycle to accumulate a total of about 15% of fat and oil when dry.
>>> I presume I now need the hydration to assist the fat-liquor to be absorbed??
By adding further Hydrator-3.3 on a fully saturated hide does not help the Fatliquor-5.0 to be absorbed. It is allowing the excess liquid to evaporate allowing further LeatherFatliquor-5.0 to be absorbed instead.
>>> It seems to be more fragile with being so moist should I let it dry out again in view of the fact the hydrator may not arrive until next week?? Should I then just massage the hydrator over the hide before attempting to use more fat-liquor?
Sounds like the hide is sufficiently relaxed, let the liquid content evaporate up to 25% dryness, and begin introducing LeatherFatliquor-5.0 once more in a repeated cycle.

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 Leather Hydrator-3.3, I saw an immediate change. I then continued with the LeatherFatliquor 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.
