If you decide to expand your garage to make more room for tools or storage, this is considered adding on to your home, and costs will typically go up. Home addition costs fall between $20,000 and $70,000 for most homeowners, depending on the size and type of space built. Your contractor will frame out new walls and expand the room's foundation. If you intend to keep the space the same only reorganizing it, you may have only the costs associated with purchasing and installing shelving and cabinetry.
Another problem is moisture vapor. Moisture vapor from the ground works from below to loosen the coating's bond with the concrete. In the case of alkyd paints (also called oil-based paints), the moisture will react with the alkaline materials in the concrete and form a soap. This process is called saponification. The soap loosens the paint's bond with the concrete. Never use alkyd or modified alkyd paints on concrete.
