Installing a new drywall on a bare wooden column requires attention to the horizontal direction of the drywall.The drywall can\'t be hung up-plumb;If so, the bottom of the sheet needs to be trimmed, and where the floor meets, they throw away the adjacent dry wall panels.As a solution, you can use a self-flat drywall laser.These rotating electronic devices project a horizontal line throughout the room.This line can be used to align the new drywall for accurate installation.Select the room area away from the drywall installation area for the laser.To maintain accuracy, the laser cannot approach the source of major vibrations such as hammering or electric tools.Place construction tripod in designated area.Spread the legs for a strong base.Roughly horizontal tripod with hands-Adjust the legs.By screwing the screws of the tripod into the thread base of the laser, the laser is fixed on the construction tripod.Tighten the screws by hand to ensure that the laser is well connected to the tripod.Press the \"On\" button of the laser.It should light up and start self-improvement.Allow the laser to reach the level of 30 seconds and start to rotate.Depending on the manufacturer, you should see a visible red or green line on all four walls of the room.Hand-Turn the handle of the tripod and lift the laser up.When the laser is lifted, its light should be turned off for the time being as it tries to compensate for the loss level.When the laser reaches the top edge of the expected drywall installation, stop turning the handle of the tripod.Hand-Tighten the fixing screw of the tripod to prevent accidental reduction of the laser.Let the laserlevel again.Observe the rotating light of the laser.It should be completely horizontal with the expected top edge of the new drywall.Align the top edge of the new drywall with a laser line.Nail the dry wall to the wall with a hammer.Continue to arrange the new drywall panels with laser lines until the wall area is covered.Reverse steps 4 and 5 to bring the laser back and off from height.
