>>> Faces of seat cushions and seat backs have faded a bit.
This leather is identified as “aniline” - that is a ‘transparent’ dyestuff like varnishing versus painting. When you unzip the cushion you would see the same color range. A good quality dye through leather has its cross section of the same color without a un-dyed layer at the center. When the thickness of the leather is hydrated the dyestuff will resurface and saturate the surface. A good dwell may take up to 72 hours, allowing the dyestuff to redistribute itself.
Further intensifying the color saturation is by faliquoring with Fatliquor-5.0
>>> The seat faces and backs have also lost some of the sheen.
Soiling and wear will show as lost of sheen, to restore will need AnilineTop-76G
>>> Any idea which products I should use to restore both the color and finish?
Recommended sequence of process is as follows:
1- Degreasing:
Body oil, grease and sweat need to be removed with Degreaser-2.2 > Rinse-3.0/Acidifier-2.0 > Hydrator.3.3
2- pH Neutralizing:
Aging sweat raises the pH value of the leather protein fiber and need to bring back to between 3 and 5 with Acidifier-2.0
3- Stain Removal:
Know stains are removed accordingly.
4- Leather Rejuvenating:
Hydrating with long dwell helps flush out penetrated soiling particulates and redistribute dyestuff prior to fatliquoring with Hydrator-3.3 > Fatliquor-5.0.
5- Color intensity is inspected for satisfaction after Hydrator-3.3 > Fatliquor-5.0.
6- A test with topcoat AnilineTop-76G for satisfaction, otherwise an option for redyeing with Aniline-76 prior to topcoat it.
Kit recommendation:
1- for topcoating use Kit-A6.tc
2- for color refinishing use Kit-A7.cl
Note: Kits are designs as a system and individual refills may be required to finish a large project.
