How to Stamp Concrete

A stamped concrete installation can go anywhere you want on a walkway or a solid surface outside. Stamped concrete, sometimes also called textured concrete, is just poured concrete that has had texture added to it before it sets, sometimes with the addition of color and specialized finishes. These processes contribute to an attractive final look for the finished installation. In some cases, textured concrete can even be used to affordably replicate the look of flagstones, brick or other materials.

Though there are contractors who specialize in concrete stamping, it is possible to complete this project yourself. Follow the steps in this stamped concrete guide to learn about the stamping process.

Stamped Concrete Installation Process

Start your installation process by gathering the materials needed for stamped concrete:

  • Concrete wire mesh or steel bar reinforcements
  • Concrete mix and the tools to mix and pour it
  • Measuring tape
  • Forms and boundaries
  • A rail
  • A float and trowel
  • Tamping tools
  • Skins, or stamps to create the texture
  • Color and sealant
  • Release agent

One you have your materials, you can follow these concrete stamping steps to ensure an even and attractive result:

  1. Decide on the look you want: One of the benefits of textured concrete is that it allows you to create a variety of looks. You’ll find many different techniques, colors and stamping methods, so it makes sense to think about the aesthetic first. For example, if you want a wood-like appearance, you will likely want to use skins and apply paint with a broom after stamping to create the look of the wood grain. Research different products to find the ones that will help you create the right finished effect.
  2. Measure the area: Careful measuring will ensure you have enough concrete mix and confirms where you want the edges to go. Make sure you open any doors or windows to verify the final, poured concrete won’t make it hard to open them. Review any local bylaws so you understand any requirements before starting your project. You may need inspections at specific points, for example, or permits for the work.
  3. Prepare the area under where your concrete will go: This area will need to be secure and well-compacted to prevent shifting and cracks in the final product. You may also need to ensure correct drainage and grade to prevent water pooling under or on top of your concrete.
  4. Install concrete forms: Forms are secured to the ground with stakes so you can pour concrete in. They keep your concrete in a specific area and allow your final project to take the right shape. Forms can also help you create a flagstone or brick look if that’s what you’re hoping to achieve, by creating separation rather than one solid surface. When placing your forms, pay attention to the bottom edges — they need to be either flush or embedded, depending on what is under your slabs.
  5. Install reinforcements: Reinforcements stay inside your concrete slab, making it more resilient to impact and helping prevent cracks. Proper placement of reinforcements can help your final project last longer.
  6. Protect nearby areas: Place sheeting around areas where concrete may splash and stain.
  7. Place concrete: Once you have the prep work complete and the right type of concrete on hand, it’s time to pour. The easiest way to do this is with a truck and chute. Make sure you have the correct mix and viscosity of concrete, then fill the forms. Once the concrete is poured, you have only a limited amount of time before it sets, so you will need to work quickly.
  8. Smooth the concrete: Smooth out and level the concrete to get it ready for stamping. Use a float and trowel to get the concrete absolutely smooth and even, then apply a release agent for your skins so you can create crisp textures.
  9. Wait for plasticity: A major part of knowing how to do concrete stamping is being able to judge plasticity — the concrete can’t be too wet or your stamps will slide and sink in too much, but it can’t be so hard that they don’t imprint. Test the surface by pressing your fingers into the concrete. They should sink in no more than 1/4 inch.
  10. Stamp the concrete: Starting at the edges, carefully apply the skins or your stamping method of choice, overlapping slightly to create a uniform look. Be sure to step back periodically for a big-picture view. Use tamping tools to evenly tamp the skins down, being careful not to step on the concrete. After tamping, peel back an edge of the skin to see how the impression looks. If it’s to your liking, carefully peel the stamp or skin up. For larger surfaces, you will need several people helping and you will likely need to work in rows.
  11. Apply color: If you want a specific color, apply it to the concrete. There are formulas you can simply pour on and distribute with a broom, which makes the process easy. Read the instructions carefully. Some color needs to be applied prior to stamping when the concrete is still wet.
  12. Add in any details: You may need to clean up some areas or use a chisel to deepen any grooves stamped too shallowly. You will also want to remove any excess concrete which has squeezed out between stamps.
  13. Cure the concrete: After the concrete has dried and you have washed off the release agent, apply a curing compound. Letting the concrete cure allows the concrete to harden and retain the correct moisture level to make the final project as strong as possible.
  14. Seal the surface: Using a quality sealant protects your hard work. Most manufacturers of sealants recommend waiting a few weeks after curing to make sure the concrete is fully dried, preventing you from trapping any moisture under the sealant. Clean and dry the textured concrete and use both a sprayer and roller to get the sealant into every crevice of the concrete in a thin, even layer.
