    Default Zebra Hide Repairs!

    Hello Roger,

    I have a zebra rug in very very poor condition and am in the process of hydrating it prior to fatliquoring. I am wondering how I guage or can calculate how much fatliquor it will require as I found when hydrating it it was so dry that it needed more than 3 bottles of hydrator applied? Can you tell by squeezing the leather once the fatliquor is applied as I cannot weigh the hide to do the calculations you have written out.

    Also there are some very badly damaged areas with degraded hide and holes would it be best to use the Stucco in combination with the suede patches on these areas? I am about to order 14 odd patches to repair the damage once I have fatliquored it...would it be better to buy a larger sheet of suede from you to cut patches myself?

    Unfortunately the hide has been stored very badly and should have been treated ages ago. I cannot seem to log in to the forum although I did register initially...it doesn't like my password anymore?! Kind regards,


    Hi Roger,

    Many thanks for your email. I have thoroughly read through everything now. My zebra is currently under plastic at my workplace warehouse saturated with hydrator. I will re visit Monday as it was hydrated Friday afternoon.

    It has many badly damaged areas which have completely deteriorated (undiscovered pet soiling I suspect). It also has multiple tears. I will attempt to dab the stains clean before fatliquoring.

    Re Fatliquoring, whilst still damp but no longer wet I should begin application of the fat liquor....Do I apply with the foam spatula as evenly as possible and let it sit for how long before the next coat? How many bottles would you see me needing? I purchased the concentrated kit for shipping purposes.

    I will send you some images on Monday but fear you will put your hand to your forehead when you see it!!!

    It is worth a try and I am sure I will restore it to at least a happier than current state no matter what. Thank goodness for you as I had no assistance from anyone locally. Kind regards,


    Hi Roger,

    As promised some images of my poor zebra!! Some completely disintegrated areas.... I have done first fatliquor today and will reapply heated formula tomorrow. Any advice how to do repairs to worst areas would be much appreciated. Kind regards,

    >>> I am wondering how I guage or can calculate how much fatliquor it will require as I found when hydrating it
    Soak it up and as long as the product stays without dripping or running is the optimum level of hydrating or fatliquoring.


    >>> Can you tell by squeezing the leather once the fatliquor is applied as I cannot weigh the hide to do the calculations you have written out.

    Yes we can tell by pressing the hide with our fingers, moisture should be oozing out.


    >>> Also there are some very badly damaged areas with degraded hide and holes would it be best to use the Stucco in combination with the suede patches on these areas?

    Bond-3D would be a stronger product and shredded suede of the same type added produces the best result homogeneously. Stucco-90 is good to easy fill non-stress areas.


    >>> I am about to order 14 odd patches to repair the damage once I have fatliquored it...would it be better to buy a larger sheet of suede from you to cut patches myself?

    There is only 1 size patch (4” x 6”). Typically is to cut a 1” x 6” strip for bonding repairs along joints.


    >>> My zebra is currently under plastic at my workplace warehouse saturated with hydrator. I will re visit Monday as it was hydrated Friday afternoon.


    Need to have in mind regarding mold growth. Example UV light present, moisture saturation level, low humidity and heat. Otherwise use KillMold-3.6.


    >>> It has many badly damaged areas which have completely deteriorated (undiscovered pet soiling I suspect). It also has multiple tears. I will attempt to dab the stains clean before fatliquoring.

    Pet soiling becomes alkaline which dentaure and ultimately rots the hide - products to neutralize includes, CleanUrine-1.5, KillUrine-1.2 and Acidifier-2.0 (product suffix denotes their pH value).


    >>> Re Fatliquoring, whilst still damp but no longer wet I should begin application of the fat liquor....Do I apply with the foam spatula as evenly as possible and let it sit for how long before the next coat?

    Application is either direct spray (wear mist mask to avoid breathing vapor) or with foam brushing. Apply until fully saturation and let it naturally dry. Before fully dry additional application may repeat and the hide is gently massaged or flexed until it dries for extra softness.


    >>> How many bottles would you see me needing? I purchased the concentrated kit for shipping purposes.


    My guess is about 4 quarts of both Hydrator-3.3 and Fatliquor-5.0 to give it another lease of life - any left overs would still be need for the next round - fatliquor is the lifeblood of hide.

    Get the hide, hydrated and supple-up before we talk about repairs.

    >>> I have nearly used up the whole fatliquor concentrate bottle...I have one more application for tomorrow. How can I tell if it is sufficient??...

    With a leather moisture meter or equivalent it should read about 15% when completely dry. Without a meter, you may test out the suppleness of the leather with strength when dry.

    >>> I intend to treat any shiny areas with hydrator and then I will let the hide dry out and gently massage it as it does?


    Good practice!


    >>> If I need to do more fatliquoring I am not going to get more product here in time from you before it dries out again. Does that mean I have to do the whole hydration process again before further fatliquoring?


    In this severe situation, it is recommended that you continue the system Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 before you do the repairs.
    Make sure the repairing areas are supple-up before repairs. Any stiff areas are a potential to crack. We shall discuss further about the repairs when the hide is supple-up.

    Hi Roger,

    >>> I have been keeping the zebra damp and applying fatliquor with distilled water the last couple of days...it is pretty sodden and now looking white when I brush the fatliquor solution over it which means to me that it is not sinking in any more....


    Before any application of Fatliquor-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 Fatliquor-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 hydrator to assist the fatliquor 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 Fatliquor-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 fatliquor?

    Sounds like the hide is sufficiently relaxed, let the liquid content evaporate up to 25% dryness and begin introducing Fatliquor-5.0 once more in a repeated cycle.
