Hi everyone,
I need help because I don't know what those black spots are around the cold room foundation. The owner told me the room gets humid, he blocked the ventilation holes because it was too cold. Could it be the reason why ? Should a cold room be ventilated in winter time ?
I'm from Montreal, Quebec so the weather varies from - 40 to + 40 celcius.
Thank you for your help.
