How much concrete would i need for a 11x11 patio while using this mold and concrete color?

Each QUIKRETE® Walk Maker® mold is nominally 2 ft x 2 ft, so to use the Walk Maker® to create a patio of 11 ft x 11 ft would require filling up the full mold 25 times, plus ½ mold 10 times, and ¼ mold 1 time, for a total of 30 ¼ “complete” molds. Each mold requires approximately one 80 lb bag of QUIKRETE® Concrete Mix to fill it, so 31 bags (of 80 lb each) would be needed. The project would be greatly simplified if the patio could be sized to be an even number of molds, i.e. 10 ft x 10 ft (25 full molds) or 12 ft x 12 ft (36 full molds). One bottle of QUIKRETE® Liquid Cement Color will color up to two 80 lb bags of concrete. Do not use more than one bottle per 60 lb bag of concrete. The color should be blended with the clean water before it is mixed with the concrete. Mixing and placing a small quantity of the concrete proportioned with the desired color quantity, and letting it cure for at least 24 hours to ensure that you are satisfied with the color is recommended before initiating the full scale project. Water, Concrete, and Liquid Cement Color quantities, in addition to application and finishing techniques, and curing conditions, must be kept consistent throughout the project or there will be color variation. Although the QUIKRETE® Walk Maker® can be ideal for creating patios, if there is going to be equipment such as a grill placed on the patio, you may consider instead pouring a concrete slab. A concrete slab provides a solid surface, without the presence of the many joints between the “stones” that will be there if a Walk Maker® is used. Please call the QUIKRETE® Technical Center directly at 1-800-282-5828 with any further questions.

You will need approximately 34 80 lb bags.
