Can this form be used to make an entire patio?

Yes, the QUIKRETE® Walk Maker® Building Form can be used for an entire patio. The nominal dimensions of the QUIKRETE® Walk Maker® Building Form is 2 feet by 2 feet by 2 inches thick. It is intended to be used over compacted stone/sand/dirt. For better results, it is recommended to remove at least the top 1 inch of the top soil and level the QUIKRETE® Walk Maker® before filling the mold with concrete.

Although the QUIKRETE® Walk Maker® Building Form 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.
