We've teamed up with Drywall Nation to show you how to run your drywall flat box on ceilings. Watch until the end or read ahead to see how to achieve the best results possible.
How Do I Run My Flat Box on Ceilings?
Start right against the wall in the corner on the ceiling, then push away and watch the mud dispense across the ceiling. If your mud is a little thick on the ceiling run your box wide open on zero, which means the tension adjuster isn't set to a number. If you run it wide open, the mud is quite thick, so if you want lighter mud you can adjust it to a higher number. Then you can start again using a butt board by Trimtex and what that does is it recesses your butt joints and creates a floating joint.
How To Avoid Bubbles and Lap Marks on Ceilings?
Once you've done the whole butt joints in one direction you'll be able to see a few bubbles and pockets in the mud. This is why it's important to run over your seams twice which is called tracing or chasing. You'll want to redo it again in the opposite direction and you'll be able to see it start to clean up very fast. Then you do your bevel coming into our butt joint and you'll run this seam on setting number 3and you'll see if faintly on the edges of the drywall. This indicates that it's not a thick enough coat so then you add another coat on a 12 inch with a much tighter coat. You want to avoid leaving lap marks next to your closest joint that way you don't have to come back and sand the lap mark.
What's The Best Way To Fill Your Flat Box With Mud?
Fill your flat box again by putting in your nozzle and filling the box back and forth until it's full. A good habit is to take your finger and just clean the back of your blade, that way if you get any little chunks of dried-up mud, you can get rid of it and stops any future dragging in your mud.

How Do You Get Rid of Drywall Christmas Trees?
Start at the butt joint and work your way towards the wall. Pull your break and you're going to come back and finish it off. Go over it a second time with your flat box and get rid of any imperfections, pits or bubbles in the mud. Then carry that lap mark right to our butt joint. Starting at the wall again take your break off and life right off at the butt joint. The lap marks in the middle of the seam are called "Christmas Trees" and have drags right at the start of the run, these are usually caused by pushing too hard and are caused by the mud flapping back from the troweling bar by the excess mud being dragged. You can get rid of this by very lightly going up over it and pull without pushing too hard and you'll be able to see the Christmas trees reducing.
