How To Apply Drywall Mud And Tape
To apply drywall mud and tape, start by cutting a piece of mesh tape slightly longer than the joint you’re working on. Press the tape firmly onto the joint, smoothing out any air bubbles or wrinkles with a drywall knife.
Next, apply a thin layer of joint compound (mud) over the tape, feathering the edges to blend it with the surrounding drywall. Allow the mud to dry completely before sanding the joints with fine-grit sandpaper or a sanding sponge to achieve a smooth finish.
Wipe away any dust, and your drywall joints are ready for painting or further finishing.
