Dustless drywall sanders are a great gizmo to help you get a nice, smooth finish on your walls without all the mess of getting drywall dust everywhere. But how exactly do dustless drywall sanders work? How will they sand the drywall without making a mess? That fine drywall dust is the bane of every home renovator - it is getting everywhere and travels further through the house than you ever would have thought achievable. But find out how dustless drywall sanders work will also give you the knowledge that you want to choose the correct one for you.

The first thing you need to know about dustless drywall sanders is that they are basically two tools put together - a drywall sander and a vacuum. Usually, the vacuum part is attached right to the back of the sander component, sucking the drywall dust away as soon as it is created. This makes it ideal for anyone who wishes to sand drywall but doesn't want to get the dust all over their house. Since most of us are doing renovations on homes that are inhabited, this can because very important. While there are other measures you can take, like putting plastic up to seal off the area you are working in, nothing will stop drywall dust like employing a dustless drywall sander.

But why does the dustless drywall sander work better than using a separate drywall sander and a vacuum? Well, as the vacuum part of a dustless drywall sander is attached directly to the back of the sander, there is no space between the 2, and no space means no chance for any drywall dust to escape and dispel. Any vacuum, regardless of how good, is not going to be ready to get right up against the sander the way a dustless drywall sander does, and there is going to be some quantity of drywall dust which will get into the air and thru the rest of your house.

When looking for your own dustless drywall sander, make sure that the vacuum is powerful enough to get all of the dust and keep up with the sander, although not so robust that the sheer amount of suction force will make the sander tough to move around. You can get a power-assisted dustless drywall sander that will add power to help in the sanding, but these sorts of sanders can get much more expensive. Unless you've got a lot of drywall sanding to do, you should be fine with a dustless drywall sander that is not power-assisted.
