How To Mud Drywall

If you plan on building a new wall, replacing drywall, or a just patching a hole, you need to know the tricks of the trade for a smooth finish.

Instructions

  • Step 1: Add water to drywall mud and apply it with the 10-inch knife until it's smooth, The mud for this coat should be thinner than the second coat.
  • Step 2: Sand the seams again until they're smooth, remembering to wear your respirator.
  • TIP: A flashlight can be used to check for blemishes in your mud. It will cast a shadow on any raised or dimpled areas, allowing you to fix them.
  • Step 3: Sand the seams one last time. Your drywall is now ready for texture, paint, or wallpaper.
  • FACT: The first Sheetrock was introduced by the United States Gypsum Company in 1916, giving builders an alternative to wooden walls covered in plaster.
  • Step 4: Add a small amount of water to mud in your drywall pan to thin it out. Then scoop it onto the 6-inch mudding knife and run it along all the seams.
  • Step 5: Sand the seams and screw dimples until they're smooth. Put on a respirator while sanding to prevent inhaling the dust.
  • Step 6: Cover screw dimples in the drywall with mud using the 4-inch mudding knife. Add mud until the dimples are flush with the rest of the wall.
  • Step 7: Scoop mud onto the 6-inch mudding knife and run the knife along any seams in the drywall to fill the crease. Use the corner trowel for the corners.
  • Step 8: Place drywall tape over the seams, including the corners, while the mud is still wet. Smooth and press the tape into the mud with the 6-inch mudding knife and allow the mud to dry overnight.
  • TIP: Clean your tools after each day of work to keep mud from drying on them.
  • Step 9: Fill the mudding pan with joint compound using the 4-inch mudding knife.
