An apparatus for holding a stackable bucket in place when mixing materials therein which comprises the stackable bucket having a bottom wall joined to a continuous tapered side wall extending upwardly therefrom to form a rim larger than the bottom wall. The stackable bucket can be placed into another stackable bucket for storage when not in use. A pair of rectangular shaped footpads are provided. A mechanism is for pivotally securing each rectangular shaped footpad into the bottom wall of the stackable bucket at an opposite side of the stackable bucket. When the rectangular shaped footpads are pivoted outwardly away from opposite sides of the side wall of the stackable bucket and the bottom wall of the stackable bucket is placed upon a floor, a person will stand upon the pair of rectangular shaped footpads to prevent rotation of the stackable bucket when mixing the materials within the stackable bucket.
