Preparing your car for ceramic coating

What you'll learn

• Whether to wash your car before the appointment or leave it dirty
• What products applied recently can interfere with coating adhesion
• What information to bring to the drop-off that affects your quote
• How to set realistic expectations about paint correction scope at the appointment

Step by step

1. Do not apply wax or sealant in the week before. Wax, spray sealant, and polymer coating products interfere with ceramic coating adhesion. If you have applied any of these recently, tell your installer at drop-off. Residues need to be removed during the prep process, and knowing in advance lets the installer allocate the right amount of decontamination time.
2. A basic rinse is fine, but skip the wax wash. If your car is filthy, a rinse helps your installer see the paint clearly during assessment. Use a pH-neutral soap and no spray wax or quick detailer at the end. If the car is reasonably clean already, leave it. Installers perform their own decontamination wash before coating.
3. Note any existing paint damage. Walk around your car before drop-off and photograph any existing chips, scratches, or swirl marks you know about. This establishes a baseline and helps you have an informed conversation about what paint correction can and cannot address at the appointment.
4. Plan for at least a full day without the car. A single-stage paint correction plus ceramic coating takes six to twelve hours depending on the vehicle size and condition. Two-stage correction takes longer. Plan transportation and do not schedule the appointment if you need the car that evening.
5. Ask about cure time before your first wash. Most ceramic coatings require five to seven days before the first wash and thirty days before the coating reaches full hardness. Ask your installer for their specific cure protocol. Washing or exposing the vehicle to sustained water in the first week can affect how the coating sets.
