Cure time

Definition

How long is cure time, and who pays for the bay?

  • Cure time is the window a coating or adhesive needs to fully harden or bond before the vehicle is exposed to water or delivered.
  • Ceramic coatings need protected cure time; PPF adhesive keeps bonding for days after install.
  • Scheduling has to leave room for it.

Why it matters to a shop

Cure time occupies a bay while earning nothing, so a calendar that does not model it will cheerfully double-book the space. Protecting the cure window is the difference between a schedule that works on paper and one that works on a Saturday. Protecting the cure window on the calendar is ceramic coating business software.

FAQ

Cure time questions, answered

How long does a ceramic coating need to cure?

Manufacturers publish their own windows, and they distinguish between the dust-free point, the point the car can meet water, and full hardness weeks later. Follow the product's own figures rather than a general rule, and put the water figure on the invoice: a coated car washed too early is a warranty conversation you both wanted to avoid.

Does PPF need cure time before washing?

The adhesive keeps bonding for days after the install, and the install itself leaves a little slip solution behind the film that has to migrate out. Small hazy patches and edge moisture in the first days are normal. Tell the customer the window, say it again on the paperwork, and the follow-up call stops happening.

Who pays for the bay while a job cures?

The shop does, unless the schedule accounts for it. Cure time occupies space and earns nothing, so a calendar that models only labour hours will cheerfully book the next car into a bay that is still holding a coated one. Blocking the cure window as real, occupied time is the difference between a schedule that works on paper and one that works on a Saturday.

Paint correctionMachine polishing that removes swirl marks, scratches and oxidation from clear coat to restore gloss and clarity. Graded by steps — a 1-step refines, a 2- or 3-step removes progressively deeper defects — and priced off the paint's condition and the bay hours it takes.Swirl marksFine, spider-web scratches in the clear coat, usually from improper washing and drying. They're most visible on dark paint under direct light and are removed by paint correction, not by wax or a quick polish.Clear coatThe transparent top layer of a factory paint system that provides gloss and UV protection. Paint correction works within the clear coat; cutting through it exposes the colour layer and means a respray, so measuring paint thickness matters.DecontaminationThe prep step that removes bonded contaminants — iron fallout, tar, industrial fallout — that a normal wash leaves behind, often with a chemical iron remover and a clay bar. Skipping it traps grit under film or coating and ruins the finish.Clay barA malleable resin bar (or mitt) dragged across lubricated paint to pull off bonded contaminants the wash missed, leaving glass-smooth paint ready for correction, coating or film.Cutting plotterA computer-driven cutter that cuts PPF or tint to a vehicle-specific pattern from a software library, instead of bulk hand-cutting on the car. It speeds installs and reduces waste, though every job still leaves some offcut. Service VIN does not cut film and does not replace a plotter: it prices the job, tracks the roll the pattern comes off, and books the bay the cutter feeds.
