Regarding the mess: Yes these certainly make a mess. I usually do it outside after making a temporary enclosure out of clear plastic and duct tape. Additionally, the warning of breathing the silica dust in is good advice.

Using a small compressor will also introduce more moisture into the air supply as it it is working harder than it should if not properly matched with any tool. Be sure to have a compressor based moisture trap and one near the tool. Nothing worse than water in your media.
