Drywall finishing is the process of preparing and smoothing the surface of drywall panels after they have been installed. This involves applying joint compound, also known as mud, to the seams and screw holes to create a seamless appearance. The goal is to achieve a flat, even surface that is ready for painting or wallpapering. The finishing process typically includes three main steps: taping, applying multiple coats of joint compound, and sanding. Each coat of compound is allowed to dry before sanding it smooth, ensuring a polished finish. Proper drywall finishing is essential for achieving a professional look in any interior space.
