This kit is great for mixing small batches of construction materials such as drywall mud, plaster, mortars and grouts. The kit includes the 56 ounce non-stick mixing ball, one 6 inch waterproof spatula mixing bit that fits in most standard drills, one 6 ounce scoop and one 8 ounce cup for easy measuring. The ball design contains the material so there is no mess while mixing. Squeeze the MixBall to dispense the mixed material out of it or scoop it out of the ball with the included spatula mixing bit. The flexible and non-stick MixBall is easy to clean wet or dry, even leftover material that has set up in the Ball pops out with ease.
