Painting Surface
Cardboard
Cardboard is a paper-based sheet material made from compressed fibers, often with corrugated fluting between liner sheets. It is lightweight and absorbent, so heavy wet coats can soften or warp it.
Cardboard paint compatibility
Acrylic and tempera work well for decorative cardboard projects, while spray paint can also work when the product approves cardboard and is applied in light coats.
| Paint | Compatibility | Preparation | Primer or ground | Finish | Guide |
|---|---|---|---|---|---|
| Acrylic paint | Excellent for decorative projects | Use clean, dry, rigid cardboard and avoid saturating the fibers with heavy wet coats. | Optional gesso for a smoother, less absorbent painting ground. | Usually optional; use a compatible clear finish only when extra handling protection is needed. | — |
| Tempera paint | Excellent for crafts and school art | Use clean, dry cardboard and keep paint and added water moderate to reduce softening or warping. | Usually not required. | Decorative; keep the finished cardboard dry and protect it from abrasion. | — |
| Spray paint | Good with a cardboard-compatible product | Remove dust, keep the cardboard dry, and apply thin even coats rather than soaking the surface. | Often not required for decorative use; follow the selected product instructions. | Product-specific; add a compatible clear coat only when needed. | — |
