4194>>> Last night a guest tripped on the hookah and a piece of coal fell on it for 3 seconds approx.
It left a black spot but fortunately no holes or serious damage occurred [Kindly check attached pics for better assessment].
The charred mark has damaged the finishes perhaps into the leather crust as well.
Preparation cleaning would involve degreasing it and fine sanding to remove surface charred prior to matching color refinishing.
Close-up pictures #2, #4 & #5 shows cracking that indicates the dryness of the leather with percentage of fatliquor running low and using a leather moisture meter or equivalent would able to read its existing fatliquor contents. Healthy leather would have a fatliquor content up to 14%, that is the original tannery standard. Any percentage of fatliquor difference would be recommended to top it up, first by hydrating it to relax and plumping the leather from stiffness and restoring back to original dimension prior to fatliquor replenishing it.
When the leather structure integrity is taken care of below the finishes the upper damaged color finishing is repair by a color restoration system comprises of Adhesor-73 > Aniline-76 > AnilineTop-76 > Protector-B+. And since Aniline-76 is a transparent dyestuff that matches the original any darkening effect will still show through. A thorough fine sanding to remove any darkening effect from the charred marks are critical when a transparent dyestuff that matches the original leather is inevitable, otherwise any blemishes will show through. To retain the original finishes characteristic a solution is to increase the degree of intensity to camouflage the blemishes but it will then involved the entire sofa to take up a new color intensity for the sake of the after cleaning and fine sanding damages. Other option just to cover up the spot may have to use an opaque pigment coloring such as Micro-54, but it would be a great difference in appearance from a fine varnish that reveals the beauty of grains to blocking off just like painted walls. The decision is yours how you would want to move in the options mentioned and I will recommend accordingly.
>>> I was wondering if you could advise me on which of your products is best geared for my case.
1 – Using matching transparent coating dyestuff may shows the blemishes unless the color intensity increases and that will involves your entire sofa to change for the sake of the possible blemishes a compromise from a deeper sanding may lessen the color intensity need to. Take note that color spotting with fresh color seldom matches faded coloring.
2 – Using matching opaque pigment is not comparable to your existing finishes; result is just like using paint for varnish repairs.
What is your option?
>>> If you can notice the scratches from normal wear
Reference to picture #6, scuffs are damaged topcoat and rough abrasions are damages into the leather crust.
Lightening scuff are repair with AnilineTop-76 either with matching gloss or satin luster to match and preparation cleaning is essential with Degreaser-2.2 > Rinse-3.0 prior to topcoat refinishing.
>>> and the feel is kinda coarse, more like a fish scale that Id like to amend as well.
Reference to picture #5 the fish scale cracking is due to dryness of the original fatliquor.
The leather first have to be hydrated with Hydrator-3.3 to relaxed the opening scale prior to fatliquor replenishing to soften it with strength from cracking.
>>> My only request would be to kindly avoid conditioners or products that could result in a glistening finish.
I feel that a glossy coating adds some undesired effect [tackiness] especially on leather furniture.
When using original tannery finishing system there is no tackiness problem just like the original and specifically AnilineTop-21 G or S does not have any history of such issue. Tackiness is also reduces when the leather is protected with a non-stick protector such as Protector-B+ leather scented or the scentless version of Protector-B. This product also reduces friction wear and reduces scuff and abration as it imparts a buttery-feel to the finish.

Leather Doctor Kit-A7.cl : Aniline Leather - Dye Refinishing Kit
Leather DoctorŽ Kit-A7.cl, aniline leather dye refinishing kit is designed for dyestuff and topcoat refinishing from the simple sunlight fading to the severely sweat damages from body oil and grease. Most severely penetrated, prolonged and neglected stains show a darkening effect with a sticky feel have its topcoat and dyestuff probably deteriorated by the sweat. When the stain feels sticky, it is a sign of leather denaturing and reverting to rawhide from breaking of bonds with the tanning agent. When sign of color is transfer to a white towel, it indicates that the dyestuff has also break bonds with the protein fiber. When leather is stiff or shows signs of whitish residue migrating, it shows that the fatliquor is breaking bonds as well with the protein fiber. The main component of the leather protein fiber is amphoteric while the other constituents are not; shifting of the pH mainly caused from sweat to alkalinity affects the pH imbalance. To revert from denaturing into rawhide prior to topcoat refinishing, contaminated alkaline soiling is removed with Degreaser-2.2, a waterbased (pH 2.2) multifunctional degreaser that emulsifies greasy contamination besides controlling dye bleeding and charging the protein fiber ionic positive for strengthening the attraction between the ionic negative tanning agent, dyestuff and fatliquor. Deflocculated and suspended soiling is towel extracted, thereafter rinse and pH balanced with Acidifier-2.0 to prevent the leather from reverting to rawhide. When leather feels sticky or slimy it is a sign of leather denaturing, a squeaky feel when wet is a sign of a healthy leather. Hydrator-3.3 relaxes stiff leathers and removes surface tension free from surface blotchiness prior to fat and oil replenishing. Fat and oil is replenished with Fatliquor-5.0 to rejuvenate the leather for the desired suppleness when dry. Custom redyeing commences prior to topcoat refinishing. Protector-B+ imparts a non-stick rub-resistant protection with a buttery-feel that shield against sticky soiling and reduce friction noises. Note that the mentioned product suffix number denotes its pH value in this holistic leather-safe aniline leathers dyestuff and topcoat refinishing system. Please email
