If you want to start a Sydney car paint repair, you must understand some of the basics of paint repair before you even think about anything else. Read on to understand treatment solutions for most common car paint finish problems.
Bleeding
This is a condition that involves the original finish of a paint repair job discolouring or the colour seeping through the topcoat colour. Some of the most common causes of bleeding include contamination. Contamination is usually in the form of pigments and soluble dyes on the older finish of the paint job before it was repainted. This issue can be prevented by thoroughly cleaning areas to be painted before you start sanding, especially when applying light colours over dark colours. If bleeding has already happened, you can solve it by applying two medium coats of primer seal or bleeder following the instructions on the label and reapplying the colour coat.
Dieback
This condition involves the loss of gloss after the application process. It is caused by improper solvent evaporation or poor initial cure. You can correct this problem by checking if the imperfections are on the whole vehicle or on a specific area. Check the other units to determine if the pattern is starting to take place. Inspect for too fast selection of a solvent and check for cool temperature during the curing process. Make sure there is adequate airflow during curing after a car paint repair job. You should also check for improper flash times and ensure you use compatible products during the paint job.
Dirt
This condition happens when there are small bumps deposited under the paint film. It is caused by foreign particles entering the wet film of paint. You can prevent this problem by checking if the imperfections are on the whole vehicle or a specific area and inspecting the other units to determine if a pattern is taking place. Check your mixing and filtration process to ensure you are doing everything correctly. Inspect the spraying environment and check the clothing of the painter to ensure it is clean. The spraying equipment should be thoroughly cleaned after use and if it wasn’t then you should clean it before use.
Dry spray
This condition involves a rough, textured surface confined to a small area. It is caused by paint that cannot flow properly. You should prevent and correct this problem by ensuring there are no imperfections in the vehicle. Check for any defects and ensure there is proper film build-up. Always maintain an appropriate distance from the surface of the car when spraying. Choose the right solvent and follow the guidelines from the manufacturer when using it.
Fish eyes
This is another Sydney car paint repair problem that should be solved. This condition involves blemishes on a small surface and this seems to occur after the paint hits the surface of the car. It is caused by improper surface preparation and cleaning. A lot of polishes and waxes contain silicone, which is the most common cause of fish eyes. Before painting your vehicle, you should do adequate cleaning and preparation.
