Identifying the Causes

Preparation Mishaps

Improper Spray Technique

Holding the spray can too far away or at an inconsistent distance from the surface can lead to blotchy application. Maintain a consistent spray distance of approximately 8-12 inches to ensure even paint distribution.

Faulty Equipment

Damaged or clogged nozzles can disrupt the spray pattern, causing uneven paint flow and blotching. Regularly check your spray nozzles and replace them if necessary.

Environmental Factors

Temperature, humidity, and wind can affect the behavior of spray paint. Spray painting in extreme temperatures or during periods of high humidity can result in uneven drying and blotching.

Curing the Blotches

Fixing Fresh Blotches

If you catch blotches while the paint is still wet, you can gently tap or brush over the affected area to distribute the paint more evenly. However, avoid overworking the paint, as this can lead to streaks or thinning.

Fixing Dried Blotches

If the blotches have dried, you can lightly sand the uneven areas with fine-grit sandpaper. Be careful not to sand too aggressively, as this may damage the underlying surface. After sanding, apply another thin coat of paint to the sanded area, ensuring even coverage.

• Always start with a clean, dry surface.
• Use a primer to enhance paint adhesion and create a smooth base.
