    Default Bicast - Is this bicast or pigment coated. .... and how do I fix the surface problem?

    Hi.
    I have had my sofas for 7 years now. Over the last few years I've had a problem with top coat wrinkling up/wearing/peeling away. Not sure what type of leather coating it has so firstly if anybody could please put me right on that one?
    The leather underneath the coating is a slightly darker shade but otherwise looks fine. Would I be better off trying to re coat the pieces that have worn or taking the coating off the rest? Looking for cheapest option really as I don't want to spend a lot. The sofa has a few cat scratches so will never be perfect again, but hoping to improve it a little! Many thanks.

    >>> Not sure what type of leather coating it has so firstly if anybody could please put me right on that one? The leather underneath the coating is a slightly darker shade but otherwise looks fine.

    Look like this is a metallic finishes with silver as the secondary top coloring and the standard opaque grey as the primary coloring. Most of secondary coloring are much weaker to wear one reason I suspect is that there should also be a sealer coating like Adhesor-73 prior to the secondary coloring coating.


    >>> Would I be better off trying to re coat the pieces that have worn or taking the coating off the rest?

    It would be better to remove the entire coating within the panel and recoating it with matching colors, otherwise where ever there is a peeling the entire section or panel have to be removed as well. Removing the secondary silver coloring is easily done with Stripper-2.3 without removing the primary color with adjustment to the Stripper-2.3 by adding distilled water just enough not to remove the primary coloring. Once the Stripper-2.3 strength is adjusted accordingly, it is as easy as spray and wipe.

    Refinishing process should take this sequence:

    1] Strip the Secondary Silver with Stripper-2.3 (stripping strength re-adjusted with distilled water from removing off the primary color).

    2] Apply Adhesor-73 for adhesion promotion.

    3] Apply Metallic-98 (Silver to match).

    4] Non-stick, Rub-resistant protection with Protector-B+ or scentless B to reduce future reoccurrence when done on a routine basis.

    Leather Doctor® Stripper-2.3 is a pH 2.3 residue free hydrocarbon formulated duality leather finish stripper with bleeding control. It is use to remove existing old finishes or overspray for all leather types.
    Instruction:
    1 Spray, agitate with stripping Brush-2 and or with leather Eraser-4 and extract with terry towel before it dries.
    Tips:
    A bristle detailing brush works into the grooves for a more thorough overall stripping unless the surface is without grain then Eraser-4 with its flat surface contact and efficient traction makes stripping much easier.
    Horsehair Brush-1 is recommended for all smooth leathers without heavy surface finishes safe against grain damages. A stiffer stripping Brush-2 is recommended for heavier finishes, however always test against grain damages. Leather rejuvenating with Hydrator-3.3 > Fatliquor-5.0 system is mandatory thereafter to restore the suppleness of the leather structure. Stripping by wetting the leather structure and when dry thereafter will leave the leather stiffer and should be handle with care from cracking it. Leather rejuvenating after inspection with Hydrator-3.3 > Fatliquor-5.0 system is mandatory to restore any discoloration from migrating dyestuff if any and returning the suppleness of the leather structure to as soft as you wish.
