How can I fix a sanded drywall joint?
assistant
The first step is to clean the area around the joint. Make sure that all loose material and dust are removed. 2 Next, apply a thin layer of joint compound to the area, then use a drywall blade or taping knife to spread it evenly across the exposed joint.3 Once the joint compound has dried, you can use a fine-grit sandpaper to smooth out the surface. 4 Finally, add another thin layer of joint compound to the area and repeat the sanding process until the joint is smooth and even with the surrounding drywall.
