Stamped concrete usually, but not always, involves placing colored concrete into preset forms for driveways, patios, walkways, floors, etc.
Before the concrete is fully set a release agent is dusted onto the surface and stamping tools are then impressed into the concrete creating a surface that resembles, brick, stone, wood, etc. in color, texture and pattern.
After 24 hours the release agent is washed off via pressure washer, and the concrete is sealed.
