That matters, because depending on use, care and age, leather can develop uneven surface tension. Without an adhesion promoter, colour products grip worse, flake off or cover unevenly. The primer builds a micro-fine grip matrix that stays both flexible and tough — a real plus for steering wheels, seat bolsters and other heavily worked leather areas. According to Koch-Chemie, the formula ties colour coats into the surface far better and makes repairs come out noticeably longer-lasting.\u003c\/p\u003e\n\u003ch3\u003ePrep, application \u0026amp; the right order for leather repairs\u003c\/h3\u003e\n\u003cp\u003eBefore you reach for \u003cstrong\u003eLeather Primer\u003c\/strong\u003e, the leather has to be cleaned and degreased thoroughly, so no residue gets in the way of the bond. You lay the primer on thin with a small sponge or cloth and spread it evenly. A fine film is enough — too much product actually weakens the grip. After a short dry time the leather is ready for COLOURLOCK Leather Fresh, Fluid Leather or other colour products. On repairs to heavily worked areas like steering wheels, seat bolsters or furniture edges it really pays to prime, to lock in a long-lasting colour bond.

Plastics like ABS, PVC or PP often have very smooth or slightly greasy surfaces that only take paint poorly. Once applied, the primer forms a micro-fine, transparent bonding matrix that later coatings can key into perfectly.
