This could be down to poor drainage, ventilation, and little natural light, all of which are a haven for mould growth, as mould thrives in damp, dark environments.
Mould is removable but you want to be able to prevent it forming as best as you can; here are a variety of ways on how to prevent mould from forming in your garage.
Dehumidifier – Installing a dehumidifier will lower the moisture levels in your garage. Water is a large factor in what causes mould, and so reducing the water within will reduce the risk of mould. A healthy level of humidity should be between 30-50% of the room, any higher than this will be a danger sign of mould to fest.
Natural light and air – if you can, open your garage door for a couple of hours a day to keep fresh air spreading throughout the space. Adequate ventilation will reduce the risk of mould forming and spreading.
Dry area – you should remove any standing water which you come across in your garage. Wipe any surfaces using a sponge to soak up any moisture to lower the risk.
Shelves – try not to keep your items on the floor and keep them on shelves if possible. This is to prevent moisture infesting your belongings which will spread throughout your garage.
Roof – check your roof is in good condition as if there are any gaps, water will find its way through. On days where the weather is very bad, this can cause a problem. This combined with bad ventilation will be a huge cause for mould to form and that is what you want to prevent. Also check your garage door too, as a lot of the doors rarely have a tight seal to the floor when shut, which allows water to get in.
Replace Cardboard – cardboard and wood are prime objects for mould to form from, this is due to the items insulating and capturing moisture in the air which forms the mould and it spreads from there. Cardboard and wood get damp very easily and quickly which is certainly not what you want in this sort of environment. Replacing these two with plastic will eliminate the risk of that happening, preventing mould from forming.
Waterproof paint – Using waterproof paint on the walls or concrete will stop moisture from sticking and forming, which is another prevention for mould to form.
Mould growth not only damages the structure of the garage but also its containments. If mould has formed it can be removed by scrubbing thoroughly with bleach and warm water, after which, drying thoroughly, but you must take safety precautions if doing so. However, if you take these points into consideration, you should be able to prevent mould from forming in your garage.
