Koch-Chemie × THE FINISHER THE FINISHER "LeatherLock" Leather Care 500ml

THE FINISHER × Koch-Chemie „LeatherLock“ — Leather care with a silky-matte OEM finish

What do I use LeatherLock for? — This leather care product conditions coated smooth leather after cleaning, refreshes color depth, maintains its natural feel without greasy shine, and makes the surface easier to care for – ideal for seats, steering wheel rims, and door panels.

THE FINISHER LeatherLock leather care is the targeted care step for modern, coated automotive leather. The fine polymer emulsion applies evenly, visually nourishes the material, reduces the appearance of dryness, and preserves the tactile, dry OEM feel. After cleaning with InsideUp or the stain-focused LeatherTexClean, LeatherLock ensures a calm, rich finish without streaks or excessive gloss – just right for contemporary interiors.

• Silky-matte OEM finish: revives color depth without greasy reflections; the surface remains dry and tactile for seat bolsters and frequently touched areas.
• Easy-care & balanced: a thin film emulsion conditions evenly and reduces visible drying out without clogging the leather structure.
• System-clean: apply to cleaned leather; harmonizes with InsideUp/LeatherTexClean as a pre-treatment and makes the next interior cleaning noticeably easier.

Leather Care – Technology, Finish & Material Understanding

Leather care for coated smooth leather works when the product acts "on top" of the layer, not in the pores. THE FINISHER LeatherLock leather care uses a finely balanced polymer emulsion that forms a thin, even film after a short flash-off time. This film smooths micro-roughness, refreshes optical saturation, and maintains the dry, non-slip feel of modern automotive leather. No greasy layer, no build-up of shine: the result looks factory-fresh. This care product is unsuitable for open-pore aniline as well as nubuck/suede – these lack the protective topcoat that our product addresses. The basis of all care remains thorough preparation: remove everyday film with InsideUp, selectively dissolve pigment/grease stains with LeatherTexClean, and only then apply care.

Application in the vehicle – Cleaning, Application, Buffing

Application should be controlled and thin. Prepare the leather dust-free and clean, then apply a few sprays of THE FINISHER LeatherLock leather care to a soft applicator pad or microfiber cloth. Distribute evenly in small sections, allow to flash off for 1–2 minutes, and gently wipe with a clean cloth side until the surface appears calm and streak-free. Seat bolsters, side bolsters, and heavily touched areas benefit from two very thin applications instead of one heavy one. Work sparingly on the steering wheel rim to maintain grip; pedals and Alcantara are taboo. Avoid direct sun and hot surfaces – the care product should set, not dry out.

Result & Routine – Tactile Feel, Color Depth, Durability

The result is a rich, silky-matte leather appearance that feels natural and gets dirty less quickly. In everyday use, it's sufficient to remove fingerprints and dust with a slightly damp cloth; more intensive cleanings are easier after treatment because dirt adheres less. A sensible routine: clean the interior, treat specific leather areas with LeatherTexClean, then apply LeatherLock thinly and wipe off. With normal use, reapply every 6–10 weeks; frequent drivers shorten the intervals, show cars can apply less often. This maintains the constant balance of color depth, grip, and ease of care – without layer build-up or a greasy look.

Frequently Asked Questions about THE FINISHER × Koch-Chemie „LeatherLock“ — Leather Care

What types of leather is LeatherLock suitable for?

For coated/sealed automotive smooth leather. Not for aniline, nubuck, or suede. Test in an inconspicuous area beforehand and only use on clean leather.

Does the leather shine after treatment?

No. LeatherLock specifically aims for a silky-matte, OEM-like finish with a dry, tactile feel – without a greasy film.

How often should I apply it?

Depending on use, every 6–10 weeks. Earlier for heavily used seat bolsters, less often for garage/show vehicles.

Can LeatherLock "repair" cracks or wear?

No. It cares for and stabilizes the appearance, but does not repair structural damage. Cracks require professional reconditioning/leather repair.

How do I prepare optimally?

First, InsideUp for everyday film, for jean stains/grease, specifically LeatherTexClean. Then apply LeatherLock very thinly and buff off cleanly.
