Yes it is. Water will alleviate the dust. Wet grinding/cutting will inhibit the airborne crystalline silica from flying in the air. You can still wear a mask, but the water will trap the dust and instead form a slurry.

Shut up

Hard to say, as we are still using the same set a year later. We've probably sanded the equivalent of 300 sq. ft. over this time here, but the pads still look near to new. The velcro backing on them is the only thing that seems to wear, and that only happens if the pad isn't seated really well onto the sander. We normally sand with water (spray bottles or sponge to apply water as we go) and so that probably prolongs the life of the pads.

Yes, these diamond pads should cut through the top layer of the cement surface, which sounds like it would remove the residual look left from the drywall mud!

We would suggest a variable speed sander yes. When using the diamond pads without water (dry) it's good to lower the speed. When using with some water, then you can speed up the rotation as the water will help them cut and reduce heat buildup.

Diamond Cups (Turbo Wheels) are generally a bad idea. Way too aggressive for a countertop. The diamond sanding discs do a great job for minimal touch up and overall profiling, prior to staining and/or sealing the concrete. If you want to polish deeper, and expose sand/glass/rock in the concrete, then you would want to use a polisher tool and resin diamond polishing pads, which will aggressively cut through the concrete. www.expressions-ltd.com/collections/concrete-polishing-and-grinding

The ideal choice is a cordless with heavy duty Velcro like these on Amazon: amzn.to/32tTp7N. We have a few of these at our shop and they work great. If you want to save a few bucks, there are cheaper sanders at that link above too, just make sure you get a variable speed version so you can slow it down.

Medium speed on a sander works well. If you have good, aggressive Velcro 'hooks' on your sander, then you can seat the diamond pads really well to the sander, and then sand at full speed if you need to (works best to use a little water when sanding fast to keep the pad cool). If you don't have great Velcro on your sander though, either upgrade it (like these on Amazon: amzn.to/3dfxiYH ) or just sand much slower to try and keep the pad seated and not burn off the Velcro on the pad!

It should feel pretty smooth. You might want to try sanding with water as well, over those rougher areas and may help cut through the sands you are most likely feeling.
