COLOURLOCK Top Coat (Car & Furniture) — Clear Coat for Durable Leather Repairs

What is COLOURLOCK Top Coat used for? — The clear coat permanently protects color-repaired leather, increases abrasion and sweat resistance, and creates a matte, satin, or glossy OEM finish for car and furniture surfaces.

COLOURLOCK Top Coat (Car & Furniture) is the professional protective sealant for all leather repairs and color refreshes. It seals the colored layer, protects it from abrasion, sweat, friction, and daily wear and tear, and ensures a uniform, original-looking finish. Depending on the chosen gloss level – matte, satin, or glossy – the look can be precisely matched to OEM automotive leather or furniture surfaces. The Top Coat is thus the indispensable final step in any high-quality leather repair.

• Durable Protective Layer – Significantly increases abrasion, sweat, and cleaning agent resistance.
• OEM-Compliant Finish – Optionally matte, satin, or glossy for perfect surface matching.
• Professional Repair Quality – Stabilizes color applications and extends the lifespan of repairs.

Technology & Mechanism of Action of the Protective Lacquer

Top Coat forms a flexible, durable polymer film that protects the underlying color long-term. Leather surfaces – especially in cars – are exposed to high stresses: sweat, friction, moisture, contact with clothing, cleaning cycles. The Top Coat seals the color surface without affecting its natural elasticity. The special formulation prevents premature loss of gloss, color abrasion, and ensures a uniformly reflective finish. In combination with Crosslinker CD, resistance can be further increased, especially for steering wheels or heavily used seat bolsters.

Preparation, Application & Best-Practice Processing

After color application or repair, the surface must be completely dry and grease-free. Top Coat is applied thinly and evenly with a sponge, airbrush, or spray gun. For a perfect finish, a multi-layer application with short flash-off times is recommended. The choice of gloss level determines the final look – matte for modern automotive leathers, satin for furniture and interior parts, glossy for decorative applications. If Crosslinker or Duller is mixed in, the components must be carefully stirred and processed promptly. Only after complete curing is the surface fully resilient again.

Results, Areas of Application & Distinction from Additional Products

After application, the leather receives a stable, easy-care, and resistant surface that permanently protects repairs. Top Coat is suitable for vehicles, furniture, bags, shoes, and all pigmented leather types. It is not a care cream and not a color – rather, it is the final protective film that completes and makes the repair durable. Duller controls the gloss level, Crosslinker increases durability, Soft Slip improves the feel. The Top Coat itself is the core of the finishing process.
