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

What does COLOURLOCK Soft Slip do? — The additive gives COLOURLOCK Top-Coats a soft, velvety feel, cuts friction and delivers a skin-friendly, luxurious finish on leather and faux leather.

COLOURLOCK Soft Slip is the pro additive for COLOURLOCK Top-Coats whenever you want a particularly soft, skin-friendly feel on leather or faux leather. It lowers the friction, improves the grip and gives you a velvety, high-end finish – spot on for steering wheels, seat cushions, furniture, bags and anywhere that should feel soft and supple to the touch. Perfect after a colour or repair job, to lift the surface to a premium level not just visually but by feel too.

• Velvety feel – Gives Top-Coats a soft, luxurious touch finish.
• Less 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 – with no greasy sheen or artificial slickness. The special additive formula stays stable in the dried Top-Coat, so the effect lasts and stays noticeable. According to the maker, Soft Slip pairs especially well with matte or satin-matte Top-Coats, since that's where the difference in feel comes through strongest.

Mixing, application & getting it right

Soft Slip mixes straight into the COLOURLOCK Top-Coat. The dose sets how intense the velvety finish turns out – a little for light smoothness, more for the softest possible feel. Once it's well mixed, 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 it works perfectly alongside other additives like Duller or Crosslinker CD. What matters is an even coat, so the grip feels consistent all over.

Results, where to use it & how it differs from other additives

Once dry, you get a pleasantly soft, almost velvety surface that feels noticeably more upmarket. Soft Slip suits steering wheels, seat cushions, armrests, furniture, bags or clothing – anywhere premium feel is the goal. It's not a gloss controller (that's Duller's job) and not a durability booster (that's Crosslinker CD). It's a pure feel enhancer that takes how a surface behaves up 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 costing you control.

Is Soft Slip suitable for faux leather too?

Yes. The effect works just as well on faux leather 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.
