The Short Answer
Professional ceramic coatings last between 3 and 10 years, depending on the grade of coating, quality of application, and maintenance routine. Consumer-grade coatings from auto parts stores typically last only 6–12 months. The difference comes down to the concentration of SiO2 (silicon dioxide) and the application process.
Factors That Affect Longevity
Several factors determine how long your ceramic coating will last. The grade of coating is the most important — professional-grade coatings have higher SiO2 concentrations and require controlled application environments. Application quality matters enormously; proper surface preparation, including paint correction and IPA wipedown, ensures maximum bonding. Your maintenance routine is the third factor — using pH-neutral soap, avoiding automatic car washes, and scheduling regular maintenance washes all extend coating life.
Professional vs Consumer Coatings
Consumer coatings available at auto parts stores typically contain 10–30% SiO2 and last 6–12 months. Professional coatings used by AquaLux contain 70–90% SiO2 and are applied in controlled conditions with proper surface preparation. This is why professional coatings last 5–10x longer than consumer products.
How to Maximize Your Coating's Lifespan
To get the most out of your ceramic coating: wash with pH-neutral car wash soap only, use the two-bucket wash method, never use automatic car washes, remove bird droppings and tree sap promptly, schedule professional maintenance washes every 4–6 weeks, and park in shade or a garage when possible. AquaLux offers monthly maintenance plans specifically designed to keep your ceramic coating performing at its peak.
When to Reapply
You'll know your ceramic coating is wearing down when water no longer beads tightly on the surface, the paint feels rough to the touch, or the gloss has noticeably diminished. At AquaLux, we include a maintenance plan with every ceramic coating application and will let you know when it's time for a top-up or reapplication.
