Product Description

Leather Doctor Hydrator-3.3 is a water-based pH3.3 leather-safe hydrator. It is mainly used as a fatliquoring preconditioner with multi functional abilities. Surface application is primary to check for even surface tension free of blotchiness prior to fatliquor replenishing. Structural application will require saturating to an optimum level with moisture oozing out when gently pressed between thumb and fingers. This universal Hydrator-3.3 is for all leather types including pigmented, aniline, vachetta, nubuck, suede, hair-on-hide and woolskin. Size options are available in RTU, Fill and Conc. RTU is (ready-to-use) straight from the bottle. Fill is concentrate ratio in the same spray bottle to be cut and fill with distilled water prior to use to save on shipping. Conc is the 60ml concentrate to be cut with distilled water at a ratio of 1: 25 that makes 1.64 quarts prior to use to save on shipping. The multi functional abilities include: A- Surface Tension Inspection. B- Leather Stiffness and Unnatural Creases Rectification. C- Structural Cleaning. D- Dye Bleeding, Leather Tackiness and Stiffness Rectification. E- Dye Fading Rectification. F- Reverse-Transfer Suspended Soiling. G- Leather pH Chemistry Integrity Rectification. H- Fatliquor Surface Residue Cleaning. I- Leather Shrinkage Rectification:                                                                                    
 
Instruction:

A - Surface Tension Inspection: Surface tension prevents liquid penetration and may result in undesired blotchiness with uneven absorption. Surface tension inspection is for even appearance of even absorption rate prior to Fatliquor-5.0 application - Instruction . . . A1- The leather surface to be fatliquored is lightly mist spray with Hydrator-3.3 evenly and wipe with lint free towel to free of surface tension prior to fatliquoring. It is then let to slow dry. A2- Fatliquored surface residue sheen when dry if any, is driven into the leather structure with Hydrator-3.3 in conjunction with appropriate brushes, converting milky residue if any to crystal clear. A3- The crystal clear moisture is towel extracted until towel shows dry. A4- When almost dry of up to 25% combine moisture content the leather is stake, stretch or massage to complete dry for desired suppleness.

B - Leather Stiffness and Unnatural Creases Rectification: Leather stiffness is fibers structure that becomes stick together when leather commonly gets wet and in most cases fatliquor leaches out. Severe stiffness results when leather lost its fatliquor under heat over-exposure and should be handle with caution from cracking it. Leather creases are unnatural wrinkles resulting from the collapsing empty leather fiber structure due to diminishing fatliquor (fat and oil) content.To plumps, relaxes and separates crushed, shrunk and stick together fibrils by manipulating away-unwanted stiffness and unnatural creases is as follows - Instruction . . . B1- The thickness of the leather is saturated to an optimum level with moistures oozing out when gently pressed between thumb and fingers with Hydrator-3.3. B2- The leather is cover up with plastic wrapping to control evaporation and let it dwell up to 72hrs for complete hydration or saturation. B3- It is then manipulate by staking, stretching, massaging or cross flexing to relax the leather to satisfaction. B4- With satisfaction and allowing up to 25% combine moisture content or when a cotton dry towel remains dry from wiping and the leather is still damp with Hydrator-3.3, fatliquoring begins before the leather is completely dry. B5- The fatliquored leather is left to slow dry and any surface shining residue is driven into the leather structure by brushing in conjunction with Hydrator-3.3 until milky residue if any turns crystal clear. B6- The surface clear moisture is extract with a cotton towel until towel shows dry. B7- Begin staking, stretching, massaging or cross flexing one more time before the leather is completely dried for the desired suppleness. Best result is manipulating the leather structure to dryness for extra desired suppleness.

C - Structural Cleaning: Structural cleaning is cleaning penetrated soiling or foreign contamination from below surface. This process includes the following steps - Instruction . . . C1- The leather is hydrated with Hydrator-3.3, depends on severity up to 72hours dwelling is recommended to moves the soiling upwards. C2- To maintain a consistent moisture level, the leather in question may be seal in container or plastic wrapping with periodic inspection to top up Hydrator-3.3. C3- The suspended soiling is extracted by squeezing between an absorbent towel and a smooth spatula to reduce abrasion until towel shows clean. C4- Fatliquoring continues and is repeated with each almost drying cycle until saturation and is leave to slow natural drying. C5- Fatliquored dried surface residue is driven into the leather structure by brushing in conjunction with Hydrator-3.3 until milky residue if any turns crystal clear. C6- Surface clear moisture is extract with a cotton towel until towel shows dry. C7- Staking, stretching, massaging or cross flexing one more time before the leather is completely dried for the desired suppleness.

D - Dye Bleeding, Leather Tackiness and Stiffness Rectification: Common alkaline overexposure may be detected moist with tackiness or sliminess from the leaching or breaking of hydrogen bond between the leather protein fibers and the tanning agents. Bleeding detected with a white cotton towel is the result of the dyestuff breaking the hydrogen bond as well. Stiffness after leather was wet and dry again is the result of the fibers becoming stick together due to diminishing or leaching fatliquor, emptying out the leather structure. To rectify alkaline overexposure areas is by facilitating colloidal water movement to redistribute the leather constituents from surrounding areas back to the affected areas. In severe cases Acidifier-2.0 is highly recommend in conjunction with Hydrator-3.3 to effectively pH balance the leather structure back to its pH neutral (isoelectric point or pI). Note, average pH of chrome-tanned leather is from 3 - 5, and vegetable-tanned leather is about 1 point lower thus more pH sensitive. Procedure sequence for rectifying alkaline overexposure of bleeding, tackiness and stiffness is as follows - Instruction . . . D1- Saturate Hydrator-3.3 into the thickness of the leather to an optimum level with moistures oozing out when gently pressed between thumb and fingers. D2- Cover up with plastic wrapping to control evaporation and let it dwell for redistributing of the leather constituents from surrounding area for up to 72hours with periodic inspection and topping up. D3- Towel extraction test for dye bleeding, finger testing to detect and eliminate undesired tackiness or sliminess for a tactile squeaky feel and relax stiffness prior to fatliquoring. D4- Fatliquoring continues and is repeated with each almost drying cycle until saturation and is leave to slow natural drying. D5- Fatliquored dried surface residue is driven into the leather structure by brushing in conjunction with Hydrator-3.3 until milky residue if any turns crystal clear. D6- Surface clear moisture is extract with a cotton towel until towel shows dry. D7- Staking, stretching, massaging or cross flexing one more time before the leather is completely dried for the desired suppleness.

E - Dye Fading Rectification: Vat-dyed leathers or aniline dyed leathers is subject to sun fading. However, the dormant dyestuff may be activated to refresh the surface with Hydrator-3.3. It will depend on richness of the dormant dyestuff and the dwell time for the hydrator to release the excess dyestuff to resurface, and result may vary from quality of original dyeing process. This is done with sufficient hydration and dwell time up to 72hours. The common practice is as follows - Instruction . . . E1- The thickness of the leather is saturated or hydrated with Hydrator-3.3 to an optimum level with moistures oozing out when gently pressed between thumb and fingers. E2- It is then cover up with plastic wrapping to control evaporation and let to dwell up to 72 hours for excess dyestuff to resurface. E3- The plastic covering is removed and let to natural dry to observe color improvement. E4- With color refreshing satisfaction, the leather is lightly wet back with Hydrator-3.3 again to relax its structure prior to fatliquoring. E5- Fatliquoring continues and is repeated with each almost drying cycle until saturation and is leave to slow natural drying. E6- Fatliquored dried surface residue is driven into the leather structure by brushing in conjunction with Hydrator-3.3 until milky residue if any turns crystal clear. E7- Surface clear moisture is extract with a cotton towel until towel shows dry. E8- Staking, stretching, massaging or cross flexing one more time before the leather is completely dried for the desired suppleness.

F - Reverse-Transfer Suspended Soiling: Capillary action or wicking process is deployed to move penetrated and suspended soiling to resurface by reverse-transfer technique with Towel-T5. First the leather structure needs to be hydrated to facilitate colloidal water movement within the structural inter-fibrillary spaces, it will also require saturating Hydrator-3.3 to move the suspended soiling upwards. As it wicks through the Towel-T5, soilings are trapped instead of still remaining on the leather surface to be easily peeled off. In practice the following steps are adopted - Instruction . . . F1- The thickness of the leather is hydrated to an optimum level with moistures oozing out when gently pressed between thumb and fingers. F2- It is then cover up with plastic wrapping to control evaporation and let it dwell up to 72 hours to loosen and suspend foreign soiling particulates. F3- The plastic wrapping is removed and replace with Towel-T5 without airspace to trap soiling as it dries instead of remaining on the surface. For it to stick onto the leather surface, the Towel-5 is spray wet with Hydrator-3.3 and brush out the air space with horsehair Brush-1 at a 45 degrees angle without tearing the towel tight. As it dries it will shrink back and tighten further sticking tight onto the leather surface. Recommend that Fatliquor-5.0 is replenished in combination at this stage especially if the leather has already show signs of cracking. Note that dried leathers with insufficient fatliquor (less then 15% fat and oil) content, when dry again will likely accelerate any existing cracking. F4- Towel-T5 is peel off when crispy dry and surface residue erase with Eraser-4 or Eraser-5 for suede accordingly prior to fatliquoring. F5- Fatliquoring continues and is repeated with each almost drying cycle until saturation and is leave to slow natural drying. F6- Fatliquored dried surface residue is driven into the leather structure by brushing in conjunction with Hydrator-3.3 until milky residue if any turns crystal clear. F7- Surface clear moisture is extract with a cotton towel until towel shows dry. F8- Staking, stretching, massaging or cross flexing one more time before the leather is completely dried for the desired suppleness.

G - Leather pH Chemistry Integrity Rectification:Leather is an amphoteric material or pH sensitive to the protein fibers. Alkalinity will shift the leather protein fiber ionic negative (-ve), while the other common leather constituents like the tanning agents, dyestuff and fatliquor are non-amphoteric and remains ionic negative (-ve). Thus like a magnet “like poles repels”, the leather constituent breaks hydrogen bond with the leather protein fiber and the leather denatures or revert to rawhide. Breaking of hydrogen bonds between the protein fibers and its constituents often manifest as tackiness, bleeding and stiffness when leather gets wet and dry again. Charging of the leather protein fibers ionic positive (+ve) has to go below its pH neutral (iso-electric point or pI) of pH 3 - 5. Thus in extreme cases Acidifier-2.0 with a pH value of 2.0 accelerate the ionic positive (+ve) charging processes to restore the pH chemistry integrity of the leather. In practice the following steps are observed - Instruction . . . G1- The thickness of the leather is saturated to an optimum level with moistures oozing out when gently pressed between thumb and fingers. G2- It is then cover up with plastic wrapping to control evaporation and let it dwell up to 72 hours for chemical reaction to take place. G3- The plastic wrapping is removed and lightly spray with Hydrator-3.3 to even out the surface and inspect for any unwanted tackiness or bleeding. G4- Acidifier-2.0 treatment may be necessary for tackiness or bleeding control. Healthy leather that is stabilized, pH balanced and ionic positive (+ve) charged should feels squeaky instead with reduced bleeding. With satisfaction to restore the leather pH chemistry integrity, fatliquoring continues. G5- Fatliquoring begins and is repeated with each almost drying cycle until saturation and is leave to slow natural drying. G6- Fatliquored dried surface residue is driven into the leather structure by brushing in conjunction with Hydrator-3.3 until milky residue if any turns crystal clear. G7- Surface clear moisture is extract with a cotton towel until towel shows dry. G8- Staking, stretching, massaging or cross flexing one more time before the leather is completely dried for the desired suppleness.

H - Fatliquor Surface Residue Cleaning: Fatliquor with its fat and oil content is essential for leather suppleness from cracking, it is meant for its structure, any surface remnants may alter its original surface luster and attracts soiling. Removing fatliquor surface residue is by brushing with appropriate brushes while spraying with Hydrator-3.3 turning the milky residue to crystal clear. When almost dry the leather is stack or massaged to dry for extra suppleness. The sequence of steps is as follows - Instruction . . . H1- Likely mist Hydrator-3.3 on surface remnants and it will turn milky. H2- Brush to drive the milky residue into the leather structure. H3- Extract until towel shows dry. H4- Staking, stretching, massaging or cross flexing one more time before the leather is completely dried for the desired suppleness.

I - Leather Shrinkage Rectification: Leather shrinkage is often experience when leather is water damaged in conjunction with fast heat drying from the sun or other heat sources. Another common dry shrinkage is from intense heat of the sun or fireplace. Heat evaporates the fatliquor (fat and oil); the leather fibers shrunk, become stick together and result in stiffness. Fatliquor is the lifeblood of leathers and with deficiency the leather stiffens up and easily leads to cracking. Rectification is as follows - Instruction . . . I1- The thickness of the leather is saturated to an optimum level with moistures oozing out when gently pressed between thumb and fingers with Hydrator-3.3. I2- The leather is cover up with plastic wrapping to control evaporation and let it dwell up to 72hrs for complete hydration or saturation. I3- When fully hydrated and relaxed it is then manipulate by staking, stretching, massaging or cross flexing the shrinkage to satisfaction. I4- With satisfaction and allowing up to 25% combine moisture content or when a cotton dry towel remains dry from wiping and the leather is still damp with Hydrator-3.3, fatliquoring with Fatliquor-5.0 begins before the leather is completely dry. I5- The fatliquored leather is left to slow dry and any surface shining residue is driven into the leather structure by brushing in conjunction with Hydrator-3.3 until milky residue if any turns crystal clear. I6- The surface clear moisture is extract with a cotton towel until towel shows dry. I7- Begin staking, stretching, massaging or cross flexing one more time before the leather is completely dried for the desired suppleness.

J - How to Lay Flat a Cowhide and other Hair-on Rug? Cowhide and other hair-on rug may not lie flat the first time or may eventually curl up again at the edges. This refuse to lay flat phenomenon is directly related to the dryness of its original fatliquor (ionic negative charged fat and oil). Optimum average percentage of fat and oil content averages 14% (read from a leather moisture meter or equivalent). Moisture meter may show percentage fluctuation of fat and oil moisture level from area to area when a rug is first put to lie flat and as the rug ages the edges that curls normally reflects drops in percentages of fat and oil content as well due to evaporation. To rectify and put the rug to lay flat to satisfaction, the rug has to be hydrated to even out its uneven tension in additional to fat and oil content replenished to increase its suppleness. Without topping up its fat and oil content the rug will stiff up and eventually leads to cracks and tears. Hydrating to preconditionering the rug prior to Fatliquoring (fat and oil replenishing) instruction is as follows . . . J1- The rug is turn over to the suede side. J2- Soiling is removed with hideBrush-4 and deteriorated fibers exfoliated with suedeEraser-5. J3- Suspended soiling is vacuum dust free. J4- The thickness of the hide is saturated to an optimum level with moistures oozing out when gently pressed between thumb and fingers with Hydrator-3.3. J5- The hide is cover up with a heavy plastic sheet for control evaporation laying flat without air space and letting it dwell up to 72hrs for complete hydration or saturation. J6- Periodically, while still damp under plastic sheet, it is then work over the plastic sheet by using a spatula from the center to the edges to flatten the lay. J7- Troublesome areas may need reapplication of Hydrator-3.3 and work over again until satisfaction. J8- With inspection satisfaction of flatten rug, the plastic sheet is removed and fatliquoring continues. J9- The hide is towel clean extracted from the center to the edges until a dry cotton terry towel shows clean and dry. J10- Before the hide dries Fatliquor-5.0 is applied and distributed with foamBrush-3” to saturation. J11- With each almost drying cycle more fatliquor is applied until the pre-determine amount is replenished to achieve the desired average 14 percentage of fat and oil content when dried. J12- The hide is left for slow drying for extra suppleness and ready to be flip over ready for use.

Hydrator-3.3 on Embossed Leather: When embossed leather is of the absorbent type (water-droplet-testing being absorbed rather then pool on its surface) any prolong hydration may relax the embossing out. Thus the long dwell hydration does not apply to embossed leather. For, stamped or embossed leathers are created by mechanical stamping or by embossing devices such as hydraulic press or roller mounted moving carriage. By exerting extreme pressure against a heated plate, the leather with the original unwanted grain pattern is replaced with an imprint of a new pattern, initiating the grain pattern of another animal or design. Traditionally, the art of hand stamping leathers has been used for many decorative purposes especially on vegetable-tanned leathers. Besides, accomplishing the purely decorative effect, stamping or embossing hides many natural blemishes or faults such as healing scars from accident, branding or parasite. Otherwise, it would downgrade in price if left alone.

Frequent Asked Questions:

>>> I finally got around to looking at the instructions to begin to apply my Hydrator-3.3 > Fatliquor-5.0 > Hydrator-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 Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system you may start with:

1-    Apply the Hydrator-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 Hydrator-3.3 with the polybrush and let it absorbed into the leather structure - keep on apply as long as it get soaks in.

3-    Use a cling wrapper to control evaporation and leave it there up to 72hrs or a 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 hydrator 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 towel until towel shows clean.

5-    While still damp, Fatliquor-5.0 is applied with the same polybrush to be fully absorbed by the leather structure. In each application cycle 83.33% of the fatliquor 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 ends the application.

6-    The leather is left for slow natural drying and surface shine is removed with Hydrator-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.

 

  1. The Lazarus Effect 5 Star Review

    Product Review - 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 Hydrater 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 sith its results.
