How to Paint 3D Printed Model Railroad Buildings

Painting your 3D printed model railroad buildings is one of the most rewarding parts of layout building.

Step 1: Prime First

Always use a plastic-safe primer to ensure paint adhesion.

Step 2: Base Coat

Apply thin coats of acrylic paint to preserve fine detail.

Step 3: Weathering

Dry brushing and washes add realism by simulating age, dirt and wear.

Step 4: Seal

Finish with a matte clear coat for protection.

Painting transforms a printed model into a realistic miniature structure.
