Smooth drywall refers to a type of wall finish that has a flat, even surface, achieved by applying multiple layers of joint compound over the seams and fasteners of drywall sheets. This process creates a seamless appearance, making it ideal for modern interior designs. The smooth finish is often preferred for painting, as it allows for a clean and polished look. It can also enhance the overall aesthetic of a room by reflecting light more evenly. Proper installation and finishing techniques are essential to achieve the desired smoothness and durability of the walls.
