If you are converting an old shipping container into a living space, you want to make it as comfortable as possible, and that includes reducing the amount of condensation that occurs in your container. Keeping condensation levels low makes the interior of the container feel less humid, and it also protects your possessions from unwanted moisture. Here are some tips to help: 

1. Focus on ventilation.

Condensation occurs when humid air hits a cool surface and causes water droplets to form there. If your shipping container has an adequate amount of ventilation, the humid air will be more likely to leave the container and less likely to linger and create water droplets.

To allow that to happen, make sure that you shipping container is well ventilated. If it comes with vents, there are typically located near the top walls of the shipping container. Make sure that these areas have access to air flow, and do not block them by positioning your shipping container flush against a house or another structure.

2. Install a humidifier.

In addition to letting humid air escape through vents, you may want to reduce the amount of humidity in your shipping container with a dehumidifier. These appliances pull the moisture out of the area, but they typically require electricity to run.

If you are not going to supply power to your shipping container, you may want to choose a non-electric dehumidifier instead. These small tools feature a desiccant or a similar product that absorbs moisture and a vessel to hold the moisture that has been collected.

3. Reduce number of wet elements in your shipping container.

In addition to controlling moist air, take steps to prevent the air from getting wet in the first place. In particular, do not put moist things such as potted plants with wet soil in your shipping container.

4. Consider painting the interior of the shipping container with grafo-therm or a similar product.

You can also reduce condensation by using special products such as grafo-therm. This anti-condensation coating is commonly used on shipping containers when they are being used to transport items, but it can also work on a shipping container that you have converted into a living space or to prevent condensation in a range of other settings. Essentially, the coating can be painted or sprayed on, and it traps moisture before it can turn into water droplets. Then, it slowly allows the water to evaporate.
