Mix the Concrete
The first layer of the concrete floor is made of Texture Pave, and will constitute most of the thickness of the floor. Texture Pave is a self-leveling cement topping, which is typically used for stamped concrete overlays, but here it's used to create a solid concrete base. Mix the Texture Pave in five gallon buckets. For each 55-pound bag of Texture Pave, mix four quarts of water. Mix using the paint mixer attached to the 1/2-inch drill. Coloring can be added to shorten drying time, but it is not necessary for the base layer.
