Koch-Chemie × COLOURLOCK COLOURLOCK "Leather Shield" Care Product for New Leather to Protect Against Wear 1000ml

Maximum abrasion protection for new leather thanks to COLOURLOCK × Koch-Chemie Leather Shield

How does COLOURLOCK × Koch-Chemie Leather Shield protect new leather? — An invisible friction-shield polymer lays down over the leather like a fine protective film, cuts abrasion on the steering wheel, door sills and seat bolsters, and keeps new leather evenly matte and clean for longer.

COLOURLOCK × Koch-Chemie Leather Shield is your pro care product when you want to protect factory-fresh or as-new smooth leather against abrasion, cracking, shiny spots and colour loss for the long haul. The formula comes from COLOURLOCK leather technology, paired with Koch-Chemie's system chemistry — perfect for new cars, lease returns and detailed interior work. Leather Shield heads off the early ageing you typically see on high-wear areas and leaves a pleasant, matte surface with a natural feel.

• Long-term friction protection – The polymer film cuts mechanical wear on side bolsters, the steering wheel and entry areas. The leather holds its shape and colour longer because micro-abrasion drops right off.
• Shine-braking effect – New leather picks up an unwanted shine fast once you start using it. Leather Shield keeps the matte look and stops greasy-looking patches, without sealing the surface or making it tacky.
• Cleanliness & easy upkeep – Because the surface energy changes, dirt grips less. Later interior cleaning goes faster and gentler, especially paired with a mild leather cleaner.

New-leather protection technology & surface behaviour

The heart of Leather Shield is a finely cross-linked polymer that bonds specifically to pigmented smooth-leather surfaces without hurting their breathability or feel. Day-to-day that means your leather still behaves naturally, stays soft, but shows far less friction-shine and micro-wear. On modern automotive leathers with a PU top coat especially, daily getting in and out, clothing edges, rivets or belt ends act like sandpaper — and the polymer film works here as a sacrificial protective layer. Per the maker's data, the formula is built so it neither builds up nor cracks, but wears down evenly and gets topped up when needed. You sidestep the classic mistakes like heavy "rubbing in": Leather Shield works best when you lay it down thin, even and fully flashed off.

Leather prep & the best way to apply it when detailing

To get maximum performance from Leather Shield, solid prep is the key. Clean new or as-new leather first with a mild leather cleaner to pull off production residue, light body oils and micro-grime. You apply the product with a soft applicator in straight, overlapping passes until you get an even film. After a short flash-off, the leather dries to a silky matte; you don't need the usual buffing afterwards because the product leaves no wax-based residue. In detail areas especially — steering wheel, console leather, side bolsters — precise work pays off. Paired with regular mild cleaning, the protection holds steady. For high-mileage cars like company vehicles or daily drivers, a quarterly top-up makes sense, since these areas take more mechanical stress.

Results, durability & typical use cases

After you apply Leather Shield, the leather's look stays factory-matte and free of the greasy shine that shows up fast on dark interiors. Durability naturally depends on use and material, since the product wears down mechanically as a protective layer. In everyday cars the benefits show strongest: even wear, less creasing and shine that turns up much later on side bolsters and steering wheels. For lease cars Leather Shield is almost a must, because it brakes visible ageing and keeps the interior feel solid right up to handover. It also holds up in professional detailing as part of a systematic leather-care process, since it's neither silicone-based nor over-conditioning and pairs perfectly with mild cleaners and later conditioner care.

Common questions about COLOURLOCK × Koch-Chemie Leather Shield

Can I use Leather Shield on older leather too?

Yes, but give older surfaces a thorough clean first and freshen them up lightly if needed. On badly dried-out leather a conditioner helps as well. That said, the product works best on as-new surfaces.

How often should I reapply Leather Shield?

With normal use, about every three to five months. Heavily worked areas like entry bolsters or steering wheels benefit from a more frequent top-up.

Does the product leave a greasy shine?

No. Leather Shield is explicitly matting and keeps the natural surface, without building up or going shiny.

Is the product suitable for perforated seats?

Yes, as long as you lay it down thin and don't "massage" it into the perforation. A light, even coat is plenty.

Can I still use a conditioner after Leather Shield?

Yes. Clean first, then Leather Shield as friction protection, then a conditioner for suppleness. That way you get protection and care in one matched system.
