Koch-Chemie × COLOURLOCK COLOURLOCK "Care & Waterproofing Oil" nourishing oil and waterproofing for smooth leather 1000ml

A nourishing care oil with water-repellent action — COLOURLOCK Care & Waterproofing Oil

What does COLOURLOCK Care & Waterproofing Oil do? — The oil feeds and waterproofs open-pore leather, visibly revives it, protects against moisture and keeps natural leather supple, tough and matt.

COLOURLOCK Care & Waterproofing Oil is the ideal care for open-pore, untreated and hard-working leathers that see moisture and abrasion day in, day out. The oil pairs deep nourishment with a water-repellent shield, so leather won't dry out, turn stain-prone or lose its natural suppleness. Perfect for leather goods in fashion, outdoor, equestrian, furniture or demanding lifestyle pieces that want a bit more protection and care without ever looking greasy.

• Feeds deep & keeps it supple – the rich formula works into the leather structure and makes up for lost moisture.
• Natural waterproofing – water beads off better and the material shrugs off damp far more easily.
• Cares without shine – the oil revives the colour without leaving the surface greasy or darkened.

Oil technology & how it works in open-pore leather

Care & Waterproofing Oil is built on a finely balanced blend of oils and fats developed specifically for open-pore leather, whose fibres soak up moisture directly. The formula doesn't sit on top as a film — it diffuses into the leather fibres, where it brings back elasticity and natural spring. The water-repellent effect comes from the fibres taking up nourishment, which leaves them less prone to drawing in moisture by capillary action. The result: the leather stays breathable, feels natural and shows better resistance to wet conditions and light soiling. According to COLOURLOCK, the recipe is tuned so it never over-conditions the material and no blotchy patches appear when you work thin and even.

Prep, application & best practice

Before you reach for Care & Waterproofing Oil, the leather should be clean, dry and free of dust. Open-pore leathers especially benefit from a gentle pre-clean so the oil takes evenly. Lay the oil on sparingly with a soft cloth or pad and work it in with circular motions until the material starts to drink it in. Wipe off any excess after a short while so you don't get uneven patches. On very dry leather, several thin coats make sense. The leather springs back to supple straight away and takes on a naturally rich, non-glossy look. Once it's dry, the piece is good to use as normal. Repeating it now and then — how often depends on where you use it and the weather — keeps the water-repellent properties topped up.

Results, typical uses & where it isn't the answer

After treatment the leather looks evenly revived, feels softer and shrugs off moisture far better. Outdoor boots, hard-wearing bags, equestrian gear and open-pore furniture leather gain the most, since they cop constant wet-and-dry cycles. The oil isn't meant for pigmented automotive leather or PU-coated surfaces — it would barely soak in there. On badly weathered leather, pairing it with intensive care, colour refresh or structural repair can be worth it. Its strength is clearly in the natural, non-coating way it repels water and the deep-down nourishment it delivers.

Common questions about COLOURLOCK Care & Waterproofing Oil

Does the oil darken the leather?

It can darken very slightly, which is normal for open-pore leather. The effect is natural and evens out after a short while.

How often should I use it?

Every four to twelve weeks depending on how hard it's used. Heavily used outdoor leather needs it more often.

Is the oil suitable for nubuck or suede shoes?

No. Nubuck and suede need dedicated products, as oil would mat the fibres together.

Can I use the oil on furniture too?

Yes, as long as it's untreated or open-pore leather. Use it very sparingly.

Does the oil work like full waterproofing?

It boosts water repellency noticeably, but it doesn't replace a heavy-duty waterproofing treatment for extreme conditions.
