How to Repair Container Houses

When repairing container houses, it is essential to focus on issues such as rust prevention and corrosion resistance, waterproof sealing, and preventing internal condensation. Here are the specific repair methods:

Rust Prevention and Corrosion Resistance

• Construction Phase: All cut and welded edges must be sanded and coated with epoxy primer and topcoat. Cutting corners in this step will inevitably lead to rust later on.
• Regular Inspections: Inspect welds, corners, bases, eaves, and other areas annually. Immediately sand and repaint any small rust spots to prevent them from spreading.
• Recoating Intervals: The recoating interval varies depending on regional humidity. In dry inland areas, recoat every 8-12 years; in humid southern regions, every 7-10 years; and in coastal areas, heavy-duty anti-corrosion recoating is required every 3-5 years.
• Elevated Foundation: Do not place the container directly on the ground; elevate the foundation to prevent the base from being exposed to moisture and reduce the risk of rust.

Waterproof Sealing

• Sealant Replacement: Replace the sealant around windows and doors, container body seams, and roof gutters every 5-7 years to ensure waterproof performance.
• Roof Maintenance: Clear leaves from the roof annually and strictly prevent water accumulation, as standing water can quickly corrode the steel plate and affect the lifespan of the house.

Preventing Internal Condensation

• Insulation and Vapor Barrier: Install qualified insulation and a vapor barrier on walls and roofs to reduce condensation caused by temperature differences.
• Ventilation Design: Ensure proper ventilation design, such as installing exhaust fans or high windows, to maintain indoor air circulation.
• Avoid Bare Steel Walls: Do not use bare steel plates directly as interior walls; decorate or cover them with other materials to reduce condensation.
