Random orbital drywall sander?

Anyone use a random orbital sander on drywall? Is this a bad idea? What grit disc should I use? I have not seen that they make drywall discs for a random orbital sander which is why I was thinking that maybe there was a flaw with my plan. TIA. Phil

I have used the ROS to sand drywall. Not the ideal way to sand. Dust will go everywhere. I hook mine to my shop vac, and that works ok but the filter clogs very quick. My sil said he used his vac with a bucket of water between the sander and vac. Claims it did good job. The drywall guy who did our family room had a sander on a wand that had rubber seal around sanding head. Hooked to large vac and created very little dust.

Phil,

Go to the rental area of your local BORG Orange. They can rent a Porter Cable drywall sander and vacuum...

Ditto on the dust isssue.

Another problem is how easy it is to sand a burred surface on the paper face of the wallboard. These get really prickly when paint is applied and necessitate additional surface repair.

I was using the hand sanding pad with the drywall sanding screen and that usualy works very well and fast, but it was making me tired and dropping a lot of dust so I decided to use my ROS. I used my Festool ETS 125 with Crysal 100G paper and vacuum. Not only did it work super fast it did so with NO dust. I love that sander / vacuum combination.
