Can diatom mud be used on the balcony? The balcony is very cold in winter.

Theoretically, it is possible. If the balcony itself will have a cold bridge, then everything you decorate will have a cold bridge, and the weather will get warmer, and the frost on the wall will have a slow frost phenomenon, which will naturally affect the function of absorbing harmful substances such as formaldehyde, so the balcony needs good ventilation? Because diatom mud itself is mud, as long as it can ensure that the balcony at home does not leak rain and is well ventilated. There is also a balcony near the outdoor, especially in winter. If your balcony leaks rain, it will be washed down and affect the appearance. The reason to ensure good ventilation is because the diatom mud itself is not good for breathing.
