COLOURLOCK Soft Slip — Top Coat additive for a velvety-soft leather surface

What does COLOURLOCK Soft Slip do? — The additive gives COLOURLOCK top coats a velvety-soft feel, cuts down friction and delivers a skin-pleasant, luxurious finish on leather and synthetic leather.

COLOURLOCK Soft Slip is the pro additive for COLOURLOCK top coats when you want a particularly soft, skin-pleasant feel on leather or synthetic leather. It lowers the friction, improves the grip and gives a velvety, high-end finish – perfect for steering wheels, seats, furniture, bags and any area that should feel soft and supple. Ideal after a colour or repair job, to take the surface up to a premium level not just to the eye but by feel too.

• Velvety grip – Gives top coats a soft, luxurious touch finish.
• Lower friction – Ideal for contact areas that should feel less tacky and nicer in the hand.
• Pro feel-tuning – Perfect as the final step after colour build-up or repairs.

Feel technology & how it works in the top coat

Soft Slip changes the surface energy of the top coat, so the final coating generates less friction. That makes the leather feel softer, smoother and more velvety – without a greasy sheen or artificial slickness. The special additive formula stays stable in the dried top coat, so the effect keeps coming through for good. According to the maker, Soft Slip pairs especially well with matte or satin-matte top coats, since that's where the difference in feel stands out most.

Mixing, application & getting it spot-on

Soft Slip mixes straight into the COLOURLOCK top coat. The dosage sets how intense the velvety finish gets – a little for slight smoothness, more for a maximum-soft feel. Once it's mixed in thoroughly, you lay the top coat down as usual with a sponge, airbrush or spray gun. The additive has no effect on colour coverage, it's purely there for the feel and works perfectly alongside other additives like Duller or Crosslinker CD. The key is an even application, so the grip comes out uniform.

Results, uses & how it differs from other additives

Once it's dry you get a pleasantly soft, almost velvety surface that feels noticeably more high-end. Soft Slip suits steering wheels, seats, armrests, furniture, bags or clothing – anywhere premium feel matters. It's not a gloss control (that's Duller's job) and not a durability booster (Crosslinker CD handles that). It's a pure feel-enhancer that lifts the surface to a classy, supple level.

Common questions about COLOURLOCK Soft Slip

Does Soft Slip change the gloss level?

No. It affects the feel, not the gloss. For matting, Duller is the right additive.

Can I mix Soft Slip with Crosslinker?

Yes. Both can go into the top coat together.

Does Soft Slip make the leather slippery?

No, just soft and pleasant. It cuts friction without taking away control.

Is Soft Slip suitable for synthetic leather too?

Yes. The effect works on synthetic leather just as well as on real leather.

When do I apply Soft Slip?

In the last step – as part of the final top coat, after colour, repair or texture build-up.
