COLOURLOCK Licker Oil — leather fatliquor for professional leather prep

What is COLOURLOCK Licker Oil used for? — The fatliquor makes dry, hard or brittle leather supple again, strengthens the fibres and improves prep for repairs, filling work and colour application.

COLOURLOCK Licker Oil is the professional fatliquor for prepping aged, dried-out or hardened leather. Hard-worked car seats, brittle furniture surfaces, old bags or saddle areas all benefit from the deep re-oiling that gets the leather fibres flexible again. Licker Oil makes sure repair materials like filler, binder or leather colour grab better and lay down more evenly. It's a key step when you want long-lasting results on leather that's gone structurally weak.

• Deep-acting re-oiling – Gets hard, dry leather supple again and cuts the risk of cracking.
• Smooths out repair work – Improves how filler, binder and colour grab and spread.
• Ideal for aged leather – Perfect for automotive, furniture, saddles, bags & accessories.

Re-oiling technology & how it works in the leather

Licker Oil works its way deep into the leather structure and reactivates dried-out fibres that have lost their elasticity over the years. The re-oiling components settle into the gaps between the fibres and bring back the natural suppleness, without darkening the leather too much. On older automotive leather that's turned brittle especially, the fatliquor lowers the risk of cracks forming during mechanical repair work. The fibres get more flexible and more receptive, which makes the whole repair more stable and longer-lasting.

Prep, application & the best way to use it before repairs

Before you apply it, give the leather a thorough prep with a suitable cleaner so the re-oiling components can soak in evenly. You lay Licker Oil down in a thin coat and work it in with light pressure. After a short dwell time the oil soaks deep in and leaves a noticeably softer surface. Depending on the state of the leather, you can repeat the process. Only once the leather is flexible again do you start the structural repair: smooth the filler, lay down the colour, seal the surface. Licker Oil clearly improves every step that follows.

Results, use cases & how it differs from a softener

After treatment the leather feels much more supple, more elastic and more receptive to products like filler, binder or colour. Licker Oil is perfect for old, dry or brittle leather in vehicles, furniture, bags, jackets and saddles. Unlike a softener such as Old Leather Softener, Licker Oil works more as a re-oiling prep and less as a long-term flexibiliser. It's the ideal first step before heavy repair work, where stability and suppleness make all the difference.

Common questions about COLOURLOCK Licker Oil

When do I use Licker Oil?

Before repairs, when leather is hard, dry or brittle and needs to get flexible again.

Does Licker Oil darken the leather?

Only slightly. The effect is far smaller than with a lot of classic oils.

Can I repair right after?

Yes, as soon as the oil has soaked in and the surface feels dry.

Is it suitable for all leather types?

Ideal for pigmented leather, finished smooth leather and many saddle and furniture leathers.

Do I also need a softener?

Only with very hard, brittle leather – then combine Licker Oil and Old Leather Softener.
