Water coatings have become a popular choice for car wash and detailing shops thanks to their ease of use, fast application, and glossy results. But even the best water coating products can underperform if applied incorrectly. Whether you’re a professional car detailer or a new car wash startup, avoiding these common mistakes can help you deliver longer-lasting shine and protection to your customers.
Top 6 Common Mistakes to Avoid
1. Skipping the Pre-Wash or Surface Decontamination
Applying water coating on a dirty or contaminated surface causes the coating to bond with the grime instead of the paint. This weakens the coating’s performance and lifespan.
Solution:
Always wash the car thoroughly using a pH-balanced car wash shampoo such as Nanolab Car Shampoo and remove contaminants with a clay bar if needed.
2. Using Too Much or Too Little Product
Over-applying can leave streaks, while under-applying reduces hydrophobic performance. Most nano water coatings only require 30–50ml per vehicle.
Solution:
Follow the manufacturer’s usage guide. For Nanolab water coating, a fine mist over each panel is sufficient.
3. Applying Under Direct Sunlight or On a Hot Surface
Heat causes the coating to evaporate or cure too quickly, leading to streaks and ineffective bonding.
Solution:
Always apply water coating in a shaded, cool area or indoors under LED lighting such as using Nanolab LED Honeycomb Lights.
4. Using a Low-Quality Microfiber or Applicator
A rough cloth or dirty applicator can scratch the paint and reduce the smooth finish expected from water coatings.
Solution:
Use high-quality microfiber towels and designated applicators for buffing and leveling the coating.
5. Not Layering or Maintaining the Coating
Water coatings aren’t permanent. Without maintenance, the protection fades faster.
Solution:
Reapply every 2–3 weeks for high-usage vehicles and offer it as a monthly upsell package or subscriptions.
6. Storing the Product Improperly
Leaving your water coating product in extreme heat or freezing conditions may ruin its chemical structure.
Solution:
Store at room temperature (15°C–30°C) and keep the bottle tightly sealed.
