Wall coatings are protective layers applied to the surfaces of walls, both indoors and outdoors. They can be made from various materials, including paint, plaster, or specialized coatings that offer additional benefits like water resistance or insulation. These coatings help enhance the appearance of walls while also providing durability against wear and environmental factors. In addition to aesthetic improvements, wall coatings can also improve energy efficiency and reduce maintenance costs. Some coatings are designed to be self-cleaning or mold-resistant, making them ideal for areas prone to moisture. Overall, wall coatings serve both functional and decorative purposes in building design.
