Tiling Container Houses

Container houses can be tiled, but attention should be paid to issues such as waterproofing, base treatment, and spatial adaptation.

1. Waterproofing is crucial

Container houses are mostly made of metal. Directly tiling them can easily lead to hollowing and detachment due to moisture, and even rust the container body. It is essential to first create a waterproof layer, such as applying waterproof coatings on the inner walls of the container or laying waterproof membranes to ensure that moisture cannot penetrate the metal structure. Moist areas like bathrooms and kitchens require special attention. You can refer to the practice in the case where "the blue gradient tiles were laid while ensuring waterproof and moisture-proof effects", and extend the service life through the dual protection of tiles and the waterproof layer.

2. The base treatment needs to be stable

The floors of container houses are usually made of metal or wood. Directly tiling them can easily cause cracking due to base deformation. It is necessary to install stable base materials:

• Metal floors: Weld steel mesh or lay cement pressure plates to enhance load-bearing capacity;
• Wooden floors: First fix a layer of moisture-proof film, and then lay cement self-leveling or fine aggregate concrete to ensure a flatness error of ≤3mm. The layered design in the case of "extending a small patio and laying wooden decks" can be used as a reference to provide buffer space for the tile base and reduce the risk of deformation.

3. Spatial adaptation needs to be flexible

The internal space of containers is limited, and the tile specifications need to match the dimensions:

• Small areas (such as bathrooms): Choose 300×300mm small tiles to reduce cutting waste;
• Large areas (such as living rooms): Use 600×600mm large tiles and lay them in a "herringbone" pattern to enhance the visual sense of extension. The flexible design of the "custom-made foldable bed in the bedroom" in the case reminds us that when tiling, space should be reserved for furniture movement to avoid functional limitations caused by a fixed layout.

4. Construction details need attention

• Joint treatment: Leave a 1.5-2mm gap between tiles and fill it with grout to prevent bulging due to thermal expansion and contraction;
• Edge reinforcement: Use metal corner strips at the corners of the container to protect the tiles from damage;
• Ventilation requirements: Keep the indoor space well-ventilated for more than 72 hours after tiling to accelerate cement curing and reduce the hollowing rate.
