Tips & Techniques for Proper Concrete Stamping

Joint the slab.

Even slabs with a deep-cut pattern must be jointed to control cracking. Use sawed joints to divide the stamped concrete into roughly square panels.

Order concrete at the correct slump.

Concrete that's too wet slows production while crews wait for bleedwater to evaporate. Concrete that's too dry or made with aggregate that's too large makes it difficult to maintain a consistent stamping depth.

Layout stamps before the concrete arrives.

Planning the stamping tool layout after concrete is on the ground burns up valuable time and increases the chances of making a mistake.

Do as little hand tooling as possible.

Minimize time spent hand tooling to fill in the pattern near the edge of a form or building by laying out dimensions of areas to be stamped in even multiples of the tool size.

Order the proper amount of concrete.

It's hard to get uniform embedment depth with the stamping tools if too much concrete is being poured because workers must start stamping while the concrete is too soft and complete stamping when it's stiff.
