How to Use Touch-Up Paint?

Simatech Color Touch-Up Paint is designed for the practical repair of stone chips, surface scratches, scuffs, and minor paint damage on vehicles. With the correct color selection, proper surface preparation, and careful application, it helps maintain your vehicle's well-kept appearance.

To achieve a successful result, follow the application steps below in order.

1. Determine the Correct Color Code

One of the most important stages of touch-up application is determining the correct vehicle color code.

Before placing an order:

  • Check your vehicle's color code.
  • Ensure the color code is compatible with the brand, model, and production year information.
  • To avoid incorrect color selection, order based on the color code specified by the manufacturer, not just the color name.

The vehicle color code can usually be found in the following locations:

  • Inside the driver or passenger door
  • On the inner door pillar
  • In the engine compartment
  • In the trunk compartment
  • In the spare tire well
  • Under the seat on motorcycles
  • On the vehicle manufacturer's information label

If you cannot find the color code, you can get support from an authorized service center using your vehicle registration and chassis number.

2. Prepare the Application Surface

To achieve a high-quality result, the surface to be treated must be clean, dry, and smooth.

Before application:

  • Clean the damaged area with water and a suitable cleaner.
  • Completely remove oil, silicone, wax, dirt, and other residues.
  • Carefully remove loose or peeling paint fragments.
  • If there is rust, clean the rusted area.
  • Use a suitable automotive primer if necessary.
  • Do not start the application before the surface is completely dry.

3. Prepare the Paint for Application

Before application, the color pigments must be distributed homogeneously.

  • Shake the paint well.
  • Open the product packaging cap in a controlled manner.
  • If possible, perform a color match test on a small, inconspicuous area.
  • Ensure that the environment where the application will take place is clean and dust-free.
  • Do not apply in direct sunlight, or in very hot, very cold, or humid environments.

Recommended application temperature: 18°C–25°C

4. Apply the Touch-Up Paint

Select the application tool according to the size of the damaged area. A fine-tipped applicator can be used for small stone chips, while a suitable brush can be used for larger areas.

During application:

  1. Take a small amount of paint on the application tool.
  2. Apply the paint in a thin layer only to the damaged area.
  3. Be careful not to let the paint overflow onto the intact surface more than necessary.
  4. Wait for the first layer to become surface-dry.
  5. If coverage is insufficient, apply a second or third thin layer.
  6. Wait approximately 10–15 minutes between layers.

Applying a few thin layers instead of one thick layer helps achieve a smoother and more controlled result.

5. Clear Coat Application

Clear coat helps increase the shine, color depth, and durability of the touched-up area against external factors.

For glossy, metallic, and pearlescent colors, a suitable automotive clear coat is generally used. For matte colors, a special matte clear coat should be preferred to ensure the surface appearance is not altered.

Clear coat application:

  1. Wait for the touch-up paint to complete the recommended drying time.
  2. Ensure there is no dust, dirt, or oil on the surface.
  3. Apply the clear coat in a thin and controlled layer.
  4. Apply a second thin layer if necessary.
  5. Observe the waiting time specified in the product instructions between layers.

Advantages of Clear Coat Application

  • Gives the surface a shinier and finished look.
  • Helps protect the paint against scratches and external weather conditions.
  • Increases UV resistance.
  • Contributes to maintaining color vibrancy for a longer period.
  • Helps the touched-up area appear more compatible with the surrounding paint.

6. Apply Metallic and Pearlescent Colors

For metallic and pearlescent colors, homogeneous distribution of pigments and thin layer application are important.

For these colors:

  • Shake the paint well before application.
  • Avoid creating thick layers of paint.
  • Apply the paint in several thin layers.
  • Allow sufficient drying time between layers.
  • Use a clear coat compatible with the paint system if necessary.

Metallic and pearlescent paints may appear duller before the clear coat is applied. Proper clear coat application helps increase color depth, shine, and surface durability.

7. Wait for It to Dry

Drying time may vary depending on ambient temperature, humidity, the number of layers applied, and paint thickness.

Average drying times at an ambient temperature of 20°C:

  • Dust-free time: Approximately 10–15 minutes
  • Touch-dry: Approximately 30–45 minutes
  • Ready for handling: Approximately 2–4 hours
  • Full cure: Approximately 24 hours

Do not touch the treated area or expose the surface to external factors before the drying time is complete.

8. Post-Application Care

After the touch-up process is complete:

  • Do not wash the vehicle for the first 24 hours.
  • Do not apply pressure to the surface until the paint and clear coat have completely hardened.
  • Do not use harsh chemical cleaners for the first few days.
  • Do not direct pressurized water closely at the treated area.
  • Protect the application area from intense sunlight, rain, dust, and humidity as much as possible.

9. Professional Application Tips

To achieve a smoother and more controlled result:

  • Use a very small amount of product for minor damage.
  • Do not apply the paint in a thick layer all at once.
  • Allow sufficient time for each layer to dry.
  • Pay attention to surface cleaning before application.
  • Prefer a dust-free, well-lit, and ventilated environment.
  • Use the application tool only on the damaged area.
  • If possible, test the first application on a small, inconspicuous area.

In Which Situations Should You Get Professional Support?

Touch-up paint is suitable for minor and localized paint damage. It is recommended to seek professional bodywork and paint support in the following cases:

  • Large surface damage
  • Deep scratches
  • Bodywork dents
  • Widespread paint peeling
  • Advanced rust and corrosion
  • Serious damage to the primer or metal surface
  • Paint problems covering multiple parts
