Ceramic coating maintenance schedule + calculator
Enter your coating, install date, and how the car is used to get a clear maintenance schedule — wash cadence, decontamination, booster reapplication, and your next maintenance date.
A ceramic coating needs a pH-neutral wash about every two weeks, a decontamination wash and a fresh SiO₂ booster every three to four months, and an annual inspection. With that upkeep it lasts two to five years. Graphene, PPF, sealant, and wax each follow their own schedule and lifespan.

Maintenance at a glance, by coating type
Baseline schedule for a daily driver garaged at night. The calculator above adjusts these for how you drive and your climate.
| Coating | Lifespan | Wash | Booster / reapply | Inspection |
|---|---|---|---|---|
| Ceramic coating | 2–5 years | Every 2 weeks | Every 4 months | Yearly |
| Graphene coating | 3–7 years | Every 2 weeks | Every 6 months | Yearly |
| Paint protection film (PPF) | 5–10 years | Every 2 weeks | Every 6 months | Yearly |
| Paint sealant | 3–6 months | Every 10 days | Every 4 months | — |
| Carnauba wax | 6–8 weeks | Every 7 days | Every 2 months | — |
How this schedule is built
Every protective layer wears down — the question is how fast, and what upkeep slows it. This calculator starts from the published durability of your coating type, then adjusts for how the car is driven and stored and (optionally) your climate. A daily driver parked outside sees more sun, rain, and road grime, so it needs more frequent washing and a shorter realistic lifespan than a garage-kept weekend car. Hot, high-UV, coastal, or salted-road climates shorten coatings further. The recurring upkeep is the same shape for the durable coatings: wash regularly with a pH-neutral shampoo, do a decontamination wash to strip bonded fallout the coating cannot shed, and reapply an SiO₂ booster (a "topper") to restore water beading between full coatings. Wax and sealant skip the booster step — you simply reapply the whole layer on a shorter cycle. The "next maintenance due" date is computed from your install date and the upkeep cadence, so you know the next action and roughly when the coating will need a full recoat or, for film, replacement. These are estimates grounded in widely published detailing norms, not a guarantee — always follow the specific care instructions for your coating product.
For detailers: turn maintenance into repeat revenue
A coating's value to your business is the return visit. With Houseler you store each customer's coating and install date, and it texts the wash, booster, and recoat reminders on schedule — so clients rebook instead of forgetting. The calculator above stays free for anyone, with no signup.
Frequently asked questions
How often should you wash a ceramic-coated car?
About every two weeks with a pH-neutral car shampoo and the two-bucket method. Washing regularly — before bird droppings, bug splatter, or road grime can dwell and etch — is the single most important habit for making any coating last. A daily driver parked outside should wash more often; a garage-kept car can stretch it slightly.
How often do you reapply a ceramic coating booster (topper)?
Most detailers apply an SiO₂ spray booster every three to four months, usually right after a decontamination wash. The booster restores hydrophobicity and self-cleaning between full coatings and is the biggest lever on how long the coating keeps performing. Graphene toppers often hold a bit longer, around six months.
How long does a ceramic coating last?
A professionally applied ceramic coating typically lasts two to five years with proper maintenance. Graphene coatings last a little longer (about three to seven years), paint protection film (PPF) lasts five to ten years, a paint sealant lasts three to six months, and carnauba wax lasts roughly six to eight weeks. How the car is used and the climate move all of these.
Do you need to wax over a ceramic coating?
No — you do not wax over a ceramic coating, and you should not. Traditional wax can sit on top of the coating and reduce its slickness. Instead, maintain a ceramic coating with a dedicated SiO₂ booster (topper), which is chemically compatible and reinforces the coating rather than masking it.
What is a decontamination wash, and how often do I need one?
A decontamination wash uses an iron remover (and clay, if needed) to strip bonded contaminants — brake dust, industrial fallout, rail dust — that a normal wash leaves behind and a coating cannot shed on its own. On a coated car, do one every three to four months, or every six months for PPF using film-safe products.
Is this maintenance schedule exact?
No — it is an estimate grounded in widely published detailing maintenance norms, not a guarantee. Your coating brand, application quality, climate, and how you drive all change the real numbers. Treat the schedule as a reliable starting plan, and always follow the specific care instructions that came with your coating.
