Proper surface preparation is essential for better adhesion, smoother finish, accurate color, and longer-lasting Mira spray paint. This guide helps you prepare surfaces correctly to prevent peeling and improve paint performance.

1. Why Choose Mira Spray Paint from An Thai Khang?

Mira spray paint is a new product line from An Thai Khang, featuring a safe formula - lead-free - no heavy metals, suitable for indoor use, outdoor use, and DIY projects.

Lightweight spray nozzle, no clogging, easy to control for beginners.
Especially when combined with the Iron spray gun (internal link), Mira optimizes paint output, improves adhesion, and saves 20–30% paint compared to manual spraying.

Using the Iron spray gun helps Mira spray more evenly, adhere better, and reduce paint consumption during use.

2. Why Is Surface Preparation Necessary Before Spraying Mira?

2.1. Remove dirt and dust – prevent paint pinholes

Dust, sand, or metal particles cause surface pinholes and uneven color.

2.2. Improve adhesion of Mira paint

Dirty or overly smooth surfaces reduce adhesion and cause peeling.

2.3. Achieve smoother and more even color

Proper preparation helps reduce the orange peel effect (rough surface texture).

2.4. Save paint and time

A well-prepared surface needs fewer coats to achieve good coverage.

3. Five-Step Surface Preparation Process

Step 1: Clean dust and debris

Wipe with a dry or damp cloth, or use an air blower.
Let the surface dry completely.

Tip: Wipe in one direction to avoid streaks.

Step 2: Degrease – the most important step

Use alcohol, white gasoline, or mild solvent.
Oil and grease prevent paint adhesion and cause paint separation.

Step 3: Light sanding to create grip

Suitable for smooth metal, stainless steel, old paint, hard plastics (ABS, PVC, PP).
Sand gently in circular motions.
Clean sanding dust thoroughly.

Note: Create fine scratches only, do not sand too deeply.

Step 4: Rust treatment

Remove rust using sandpaper or a wire brush.
For heavy rust, apply an anti-rust primer before painting.

Step 5: Final cleaning

The surface must meet three conditions: dust-free - oil-free - dry.

4. Five Tips to Help Mira Paint Adhere Better and Last Longer

Spray the first coat very thin.

Keep a distance of 15–25 cm.

Shake the Mira can for 20–30 seconds.

Avoid spraying under strong sunlight or windy conditions.

Apply 2–3 thin coats instead of one thick coat.
