Product Overview
Kit SA7.cl is a professional-grade system for a leather complete refinishing solution.
Leather color refinishing is often necessary due to:
A long-lasting restoration requires addressing both the leather structure and surface finish:
- The average leather thickness of 0.9–1.2 mm determines its strength and flexibility.
- Dryness leads to stiffness and eventual cracking.
- The outer color finish averages 0.02 mm (20 microns) and must remain compressible and flexible to avoid cracking from use.
Deep-Cleansing, Leather-Safe Degreaser for All Leather Types:
Acidifier 2.0 prevents leather from denaturing, which can lead to bleeding, streaking, tackiness, and structural weakness due to alkaline overexposure.
Adhesor 73 effectively builds a uniform surface over rough or abraded areas on all smooth leathers. Additionally, Adhesor 73 assists in removing deteriorated finishes, repairing abraded surfaces, and reactivating aniline dyestuff to some extent.
Pigment 54 is highly recommended for refinishing high-end semi-aniline and pigmented finishes, seal with Topcoat 54.

Concentrate products offer several advantages, especially in terms of saving, convenience and efficiency:
A holistic leather color refinishing system works in a progressive sequence dovetailing to the desired result with these 7 steps:
Stripping of deteriorating finishes to even the overall appearance with Stripper 2.3 and rinse with Rinse 3.0 is the first step, otherwise, skip to degreasing.
Degreasing with Degreaser 2.2 followed by Acidifier 2.0 is mandatory to remove accumulated oily, greasy, sweaty soiling, and aging conditioners for an overall even appearance.
Hydrator 3.3 followed by Fatliquor 5.0 rejuvenates leather for its renewed softness and strength.
Adhesor 73 is a compact primer resin that ensures proper smoothing, sealing, and promotion of adhesion to the leather before color coating.
Micro 54 is a fine micro pigment water-based compact resin blend with high UV fade resistance to provide the desired color.
Matte 54 seals Micro 54 has excellent flow, and forms a flexible, tough film in gloss, satin, or matte.
Protector B is a non-stick, rub-resistant protection conditioner that cuts friction noise and imparts a soft buttery feel on smooth leather. Protector B Plus is the leather scent version.
Stripper 2.3 is applied and unwanted finishes are removed with tools like Brush 9, Eraser 4, Razor 60, sandpaper feathering out seamlessly, and towel extract for an even appearance.
- Degreaser 2.2 is swirled for up to 5 minutes for the separation to build up above 75% of coagulation, then given a vigorous shake to gel for ease of application.
- Degreaser 2.2 is transferred to Brush 1 or Eraser 4; agitate to saturate the body stain, and feather out to the entire section.
- Suspended soiling is towel extracted until the towel shows clean.
- Acidifier 2.0 is applied, brushed, and suspended soiling is rinsed with towel extraction until the towel shows clean to a healthy squeak.
- Existing brightening streaks, or tackiness if any, are pH balanced with a dwelling soak and brushing to remove suspended foreign contamination to a healthy squeak with finger testing.
- Hydrator 3.3 is applied saturating the stain area and feathering out for an even appearance.
- Hydrator 3.3 soaked Towel 5 is placed over the stain area without airspace to trap suspended soiling particulates instead of remaining on the leather surface as it dries.
- Towel 5 when crispy dry is peeled off and Eraser 4 is used to erase surface residue before fatliquoring.
- Hydrator 3.3 is applied and brushed to the entire panel for a darkening appearance without a drying edge.
- Hydrator 3.3 relaxing effect is further worked out with stretching and massaging to eliminate leather stiffness to satisfaction.
- A towel extraction follows until the towel is clean and ready for immediate fatliquoring.
- Fatliquor 5.0 is applied to the entire panel with a darkening appearance without a drying edge.
- Fatliquor 5.0 application is repeated each time the water contents evaporate until fully saturated.
- Fatliquored leather is left to a slow natural drying.
- Hydrator 3.3 is applied to the sticky surface and brushed with Brush 1 driving the remaining surface remnants free of milky fat and oil until it turns clear.
- The non-sticky surface is given a final towel wipe and is left to dry again for natural drying.
- The almost dry leather is given a stretching or massaging until dry for an extra softness.
- Dry prep is the preparation with various tools like a tablespoon to stretch out any darkening effect, Eraser 4 to erase surface wick-up residue, and sanding to smooth deteriorating finishes.
- Refer to Leather Repair Kit A7.r for the various types of repair accordingly.
- Adhesor 73 is scrubbed with a 3M white pad to remove some deteriorating finishes and lint-free towel extract until the towel shows clean to promote an even adhesion coating for further coating.
- Pigment 54 concentrate has to be mixed with distilled water before application.
- The mixing ratio may vary from a ratio mix of 1: 0.5 to 1 with less distilled water to retain its viscosity to control streaking on a vertical panel when coating by airbrushing.
- First coating is recommended with padding using folding Foam 2 and/or Towel 5 to rub in for better surface bonding and subsequent coating with roller brush, soft varnishing brush to reduce streaking or airbrushing to produce professional results.
- Fine dry atomize dispersion with more air is achieved with 80 to 100psi of air pressure.
- Recommend a light spray for easy blow dry in-between coating building up the color in the process.
- Matte 54 is applied by a soft varnishing brush to reduce marks and streaks or airbrushing for professional results.
- Use a lint-free paper towel to blot out any drips or streaks.
- Speed dries between coats with the help of a hair dryer.
- 2000-grit sanding may be applied to improve touch and appearance.
- Protector B is applied and redistributed with a foam brush or lint-free white towel and ready for use when dry
- Color matching is created from the basic color in parts based on weight from these examples.
