Introduction: Decorative Concrete - Pinstripe Aggregate

Picture of Decorative Concrete - Pinstripe Aggregate

The pinstripe aggregate method uses corrugated craft board to help achieve a pinstripe pattern of exposed and unexposed aggregate.

The craft board creates a corrugated pattern in the surface of the concrete. After the concrete is set, the hills are ground down to expose the aggregate, but the valleys remain un-ground, creating contrasting lines of exposed aggregate and lines of no exposed aggregate.

In this instructable, I also added some white paint to the valleys to help highlight the effect.

Step 1: Things You Will Need


  • dust mask
  • latex gloves


  • white cement
  • blue sand
  • water


  • larger diameter tube
  • smaller diameter tube
  • corrugated craft board
  • spray glue


  • disposable cups
  • popsicle sticks
  • paint brush
  • white paint
  • knife sharpening stone (or other sanding/grinding tools)

Step 2: Instruction Video

Refer to the above instruction video for a demonstration of the method.

If you would like any further clarification or support on any of the steps, please feel free to leave me a comment and I will help as best as I can.


This is a great way to get a cool texture!
