Mudding drywall can be a difficult home improvement task. It is important to apply the mud properly and to finish it smoothly in order to achieve the best results.

Step 1 – Waiting for the First Layer of Mud to Dry

It is important to be sure that the first layer of mud is completely dry before you apply a second layer over the taped area. Inspect the area and gently run your fingers over the mud to check it. Sand the dry first layer until it is smooth and even.

Step 2 – Applying the Second Layer of Mud

Thin out the second layer of mud with water. Beginning at the top, apply the second layer of mud with a six-inch putty knife. Use long, even strokes to apply a thick layer over the taped area. Apply more pressure on the sides of the seam.

Step 3 – Smoothing Out the Mud

Spread the mud out about three inches on either side of the seam. Be sure to apply a thick layer of mud over any indentations in the drywall. Allow the mud to dry thoroughly. Sand the second layer of mud until it is smooth and even.
