Know How Many Mats You'll Need for the Job

Your window of opportunity for stamping is limited, especially in warmer weather when the concrete sets more quickly or when you're stamping a thin overlay. That makes it essential to have enough stamps (and workers) to complete the job without interruption.

The general rule is to have enough mats on hand to extend across the full width of the area to be stamped plus a couple of additional mats to start the next row. You will also need at least one floppy or texture skin and a tamper to impress the mats into the fresh concrete. Some small jobs, such as a walkway or patio, may only require a few stamps. Commercial projects may require 20 or more stamps so crews can work on several rows at a time.

To accurately figure out how many stamps to purchase, you need to know the dimensions of the tool of choice, says Harris. For example, if you plan to purchase 24x24-inch stamping mats for a residential driveway 20 feet wide, you would need 10 mats to span the 20-foot width, plus two additional tools.
