Container House Interior Tiling

Container houses can have tiles installed indoors, but targeted treatment must be carried out in combination with structural characteristics and construction key points.

I. Structural Reinforcement is Fundamental

The original structure of a container house is corrugated metal sheets, which have limited load-bearing capacity. If large-area tiling is required, the wall surface must be reinforced first. Common methods include:

1. Light steel keel frame: Weld or bolt-fix light steel keels on the surface of the metal sheets to form a grid-like support structure, enhancing wall stability.
2. Cement fiberboard covering: Install cement fiberboards on the outer layer of the metal sheets to provide a flat and sturdy base layer while improving fire resistance.
3. Insulation layer treatment: If the container does not have a built-in insulation layer, insulation materials such as rock wool or polyurethane should be installed before tiling to prevent tiles from detaching due to temperature changes.

II. Base Layer Treatment Requires Precision

Before tiling, ensure that the base layer is flat, dry, and free of oil stains:

1. Rust prevention treatment: Grind and derust the metal surface and apply anti-rust paint to prevent tile hollows caused by rust after long-term use.
2. Waterproof layer construction: In wet areas such as kitchens and bathrooms, apply waterproof coatings first and conduct a closed-water test to ensure no leakage before tiling.
3. Interface agent application: Apply a special interface agent on metal or cement base layers to enhance the bonding strength between tile adhesive and the base layer.

III. Tile Selection and Construction Key Points

1. Tile specifications: Prioritize lightweight and thin tiles to reduce the load on the structure. Avoid using large-sized tiles to lower the risk of detachment.
2. Tile adhesive selection: Use high-strength tile adhesive instead of traditional cement mortar to ensure that the bonding strength meets the requirements of metal base layers.
3. Joint treatment: Reserve 1.5-2mm gaps between tiles and use flexible grout to accommodate possible minor deformations of the container.
4. Construction technique: Adopt the 'thin-bed method', which involves evenly applying tile adhesive with a toothed trowel to form striped textures, increasing the bonding area and preventing hollows.

IV. Special Area Treatment

1. Corners and joints: In stress-concentrated areas such as container corners and door/window openings, use metal reinforcement parts or flexible sealing materials to prevent tiles from cracking due to structural deformation.
2. Floor tiling: If tiling is required on the container floor, first lay cement self-leveling to ensure flatness, and then use tile adhesive for tiling.
