Have you heard this before?

“Wet-on-wet” coating leads to:

❌ Wrinkling

❌ Color fading

❌ Bubbling

❌ Poor adhesion

That’s why many painters wait 8, 12, or even more hours before recoating.

But today, we put it to the test—5 steel plates to show you if wet-on-wet really works!

Step 1: Paint Mixing

Base and topcoat mixed by ratio, stirred evenly, and left to de-aerate.

Step 2: Surface Prep

Steel plates sandblasted to Sa2.5, roughness controlled at 35–75 μm.

Step 3: Primer Application

Basecoat uniformly sprayed, wet film thickness controlled. Some plates move directly to topcoat (wet-on-wet).

Step 4: Film Thickness Check

Wet film gauge used to confirm consistency in film thickness.

Step 5: Topcoat Application (Wet-on-Wet)

Topcoat applied directly without drying time to test wet-on-wet results.

Step 6: Curing Observation

Observed for color, gloss, wrinkling, fading, and bubbling.

Step 7: Adhesion Cross-Cut Test

After full curing, cross-cut tape test performed to assess adhesion level.

Test Results:

✅ Strong adhesion

✅ Smooth finish

✅ No defects observed

Yes—Mengneng Coating supports wet-on-wet!

The key lies in: formulation + environment + application timing control
