Mold in a garage is not uncommon and can quickly appear even in a new garage. A garage can create a perfect environment for mold, mainly due to significant climate, temperatures, and humidity level changes. To eliminate the potential mold issues in a garage follow these simple steps: \tEnsure that most of the moisture coming from cars to the garage is either wiped off the vehicle or squeegeed out shortly after the water, snow, or ice is found on your concrete slab. \tEnsure you maintain a steady temperature in the garage. If you have a heated garage and you decide to heat it during the cold months it's imperative to maintain a steady temperature. Turning the heat on and off on a regular basis will create condensation around the walls, insulations, attic space, trusses, and other components. The condensation then will then turn into droplets and end up being trapped in these places which in no time will turn into mold \tDon't store boxes, or wooden shelves directly on the floor. Instead, install those on walls or ceiling \tConsider installing a dehumidifier, or other dehydrators such as silica gel and molecular sieves. This will help trap all the excess moisture from the air and keep your garage dry \tMake sure the downspouts didn't bend and turned away from coming directly into the garage \tConsider applying a polyurethane or epoxy coating on your slab or paint the slab.
