Paddle mixers are simply designed for quick and easy mixing of various substances (i.e., plaster, paint, and gypsum jointing compounds). A paddle mixer (not unlike a cake mixer), has rotating blades on them allowing for ease of mixing with a few lumps and bumps as possible. That, coupled with varying speed control allows you to mix freely with as little splashing as possible. And, depending on your work style, you can have an electric cable or battery-powered paddle mixer. If you like to work fast, efficiently, and with as little strain on your arms as possible, then you really can’t go wrong with a powered paddle mixer.
