How to Sand Drywall?

Assuming that you will use a power sander, here, I will show the steps to sand drywall in a proper manner.

Step 1: First you need to cover the entire room with plastic so that the furniture and the floor are protected from the powder.

Step 2: Switch off the air conditioner/fan. It will prevent the air from carrying dust to other rooms.

Step 3: You need to protect your eyes from the dust. So, it’s imperative that you put on eyeglasses before you get started.

Step 4: There will be plenty of noise during the sanding. Hence, wear ear protection before you begin sanding.

Step 5: You will need to set a ladder if you intend to do ceilings.

Step 6: Connect the device to a vacuum system.

Step 7: Attach your desired sanding disc to the head of the device before you plug the device in. Be careful as not to put too much pressure since it could damage the wall.

Step 8: Once you are done with sanding drywall, vacuum clean the entire room.
