Koch-Chemie × COLOURLOCK COLOURLOCK "Leather Primer" adhesion promoter for leather base and colour 1000ml

COLOURLOCK Leather Primer — adhesion promoter for proper colour bonding on leather

What's COLOURLOCK Leather Primer for? — The primer lays down an evenly grippy surface, stabilises the leather structure and clearly improves how colour and repair products like Leather Fresh or Fluid Leather bond to it.

COLOURLOCK Leather Primer is the pro-grade adhesion promoter for any leather repair where a colour refresh, a re-dye or structural build-up has to hold. The primer preps the leather surface properly, boosts how well COLOURLOCK colours and fillers grip, and makes repairs more durable, more even and visually cleaner. Spot-on for car, furniture and fashion pieces, plus every pigmented leather that needs degreasing, stabilising and made grippy before a colour correction.

• Better colour grip – The primer keys into the leather surface and gives following colour coats something solid to hold onto.
• Even repair finish – Spot-on before Leather Fresh or Fluid Leather, so the colour covers evenly instead of going patchy.
• Pro repair base – Stabilises the surface structure and cuts down on grip problems on smooth or lightly sealed leathers.

Adhesion technology & how it works

Leather Primer uses special binders that key into the top leather or PU finish layer while building an ideal base for the COLOURLOCK colours that follow. That matters, because depending on use, care and age, leather can develop uneven surface tension. Without an adhesion promoter, colour products grip worse, flake off or cover unevenly. The primer builds a micro-fine grip matrix that stays both flexible and tough — a real plus for steering wheels, seat bolsters and other heavily worked leather areas. According to Koch-Chemie, the formula ties colour coats into the surface far better and makes repairs come out noticeably longer-lasting.

Prep, application & the right order for leather repairs

Before you reach for Leather Primer, the leather has to be cleaned and degreased thoroughly, so no residue gets in the way of the bond. You lay the primer on thin with a small sponge or cloth and spread it evenly. A fine film is enough — too much product actually weakens the grip. After a short dry time the leather is ready for COLOURLOCK Leather Fresh, Fluid Leather or other colour products. On repairs to heavily worked areas like steering wheels, seat bolsters or furniture edges it really pays to prime, to lock in a long-lasting colour bond. The order is always: clean → degrease → Leather Primer → colour → protect/care.

Results, where to use it & the payoff in detail

After you've laid it down, the surface reads more even, more stable and far more ready to take colour systems. Colour corrections cover better, transitions look softer, and the repaired patches hold up longer. Leather Primer earns its place in every pro leather restoration, especially on leather that's very glossy, has been cared for with silicone-heavy products or simply offers a tricky base to grip. It replaces neither the cleaning nor the care step — it's the essential in-between step for high-quality, long-lasting colour build-ups. The product suits vehicles, furniture, bags, clothing and every type of pigmented leather.

Common questions about COLOURLOCK Leather Primer

Do I have to use the primer before every colour refresh?

We'd recommend it — especially on worn or poorly gripping surfaces, to lock the colour in properly.

Is the primer also suitable for aniline or nubuck leather?

No. It's built purely for pigmented smooth leather.

How long does the primer need to dry?

Usually a few minutes. The surface should be dry and matt before you put colour on.

Can I use the primer without a colour correction afterwards?

No. It's an adhesion promoter and works only as a prep step for colour or repair products.

Does the primer improve how well Fluid Leather lasts?

Yes. The repair compound bonds noticeably more solidly and stands up better to mechanical stress.
