COLOURLOCK Top Coat (Dull) — matte sealing lacquer for an original leather look

What is COLOURLOCK Top Coat Dull used for? — The matte sealing lacquer seals repaired or recoloured leather, protects the surface against abrasion and gives you an even, original matte look with no shine.

COLOURLOCK Top Coat (Dull) is a matte sealing lacquer for the professional finishing of leather surfaces after repair or recolouring work. It reliably protects the colour layer against abrasion, friction, skin oils and everyday wear, and at the same time builds an even, natural matte look. On modern automotive leather, furniture and interior parts in particular, a matte finish is what keeps the original appearance intact.

• Original matte look – No unwanted shine, an even finish.
• Protects colour & repairs – Cuts down abrasion and premature wear.
• Professional sealing – For long-lasting, hard-wearing leather surfaces.

Sealing-lacquer technology & how it works

Top Coat (Dull) forms a fine, flexible protective film over the leather colour or the repair build-up. The matte formula scatters light on purpose, which kills the shine and gives you an authentic, factory look. The surface stays flexible too, so it moves with the leather instead of fighting it. The lacquer reliably protects against mechanical stress without leaving the leather feeling hard or artificial.

Application, layering & best practices

Once the leather colour or repair build-up has dried fully, you lay down COLOURLOCK Top Coat (Dull) thin and even. Best applied by spray or with a fine-pored sponge in several light coats. Give it enough flash-off time between coats. For high-wear areas you can mix the top coat with a crosslinker (e.g. IC2) to push durability even further.

Results, where it fits & where it doesn't

Once cured, the leather surface is matte, even and noticeably tougher. Top Coat (Dull) works on car seats, steering wheels, door panels, furniture, bags and other pigmented smooth-leather surfaces. It's not a care product — it's a functional sealing lacquer for repair and recolouring work. Next to glossy or high-gloss versions, it gives you a subtle, original finish with no reflections.
