Painting on the Exterior of Container Houses

Painting on the exterior of container houses requires selecting appropriate materials and following standardized steps, while also considering structural characteristics for design to ensure aesthetic appeal and durability.

I. Material Selection

1. Primer: Use specific water-based paint mixed with outdoor high-weather-resistant color paste to create the base color. This type of material stabilizes the substrate and enhances the adhesion of subsequent paints.
2. Paint: During the painting phase, select specific water-based paint mixed with colored paint or matte acrylic for color blending. These materials are waterproof and sun-resistant, ensuring color longevity. For detailed work, use small brushes to ensure even coverage over the tiny irregularities on the iron surface.
3. Varnish: After painting, apply a roll of varnish to form a protective layer that resists dirt and sun exposure, slowing down the fading of the paint.

II. Operational Steps

1. Mix Base Color and Dilute for Rolling: After mixing the water-based paint with color paste in proportion to create the base color, add 20%-30% water for dilution and evenly cover the container surface by rolling. This step requires ensuring a flat substrate to avoid affecting subsequent painting effects.
2. Outline the Design: After the primer is completely dry, use light-colored chalk to outline the pattern on the surface. The ease of modification with chalk reduces the risk of design errors.
3. Color Blending and Painting: Mix paints according to design requirements, starting with filling in large color blocks and then gradually handling details. When painting, pay attention to the irregular structure of the iron surface and adjust the brushstroke direction to ensure even paint coverage.
4. Varnish Application: Within 24 hours after painting, apply a roll of varnish to form a transparent protective film. This step requires controlling the rolling thickness to avoid sagging or bubble formation.

III. Design Considerations

1. Structural Adaptation: Fully consider the irregular surface features of the container. For example, in the case of the Dreamy Manor by Uncle Tai in Jurong, Zhenjiang, by blending pop art styles with three-dimensional patterns, the cold iron surface was transformed into a visual focal point.
2. Perspective Framework: When hand-drawing the design, first draw vertical lines to determine the height, then set perspective vanishing points on both sides to construct a two-point perspective rectangular framework. Enhance the layering of the image by marking the positions of doors and windows and highlighting structural elements such as eaves.
3. Detail Optimization: After determining the basic shape, add附属 structures (affiliated structures, here meaning supplementary elements like platforms) to enrich the image content. During the painting process, regularly check color uniformity and promptly repair any missed areas.
