To attach the sanding screen, check the sander head for clamps. Loosen the clamps and start inserting the screen. Center the screen properly and then tighten the clamps so that they hold the screen securely.

4. Sanding the Wall

Turn the vacuum on to begin the suction action. Adjust the pressure. Now place the sander head on the wall and begin sanding by making long strokes.

Check to see if the walls are smooth or not, and repeat the stroking motion as necessary. If you find you’re sanding sheets ripping or any damage to the walls, you will need to readjust the pressure of your vacuum.
