For this concrete patio at a home in Fredericksburg, TX, SUNDEK of San Antonio created the look of stone using SunStone and a blend of colors.

Can you make concrete look like stone?

Yes! Natural stone patios and pool decks are beautiful, but the cost and installation process can feel out of reach for many homeowners. The good news is that you can achieve a similar upscale appearance using a concrete overlay that looks like stone. With the right textures, colors, and techniques, existing concrete can be transformed to resemble flagstone, slate, limestone, and more—helping homeowners upgrade worn or outdated surfaces while boosting the overall appearance of their outdoor spaces.

How do you make concrete look like stone?

Though it’s not a simple process, with the right materials, colors, techniques, and tools, an experienced contractor can mimic the look of stone on a concrete surface using concrete coatings.

Here is a general overview of the process:

1. Prepare the surface. Remove materials from the existing concrete surface. This includes things such as tiles, grout, paint, old sealer, and more.
2. Profile the concrete. Grind or sand the surface to make it porous. This will allow your concrete to accept the coating, helping it adhere to the surface.
3. Clean thoroughly. After removing materials and grinding or sanding, you’ll want to give the surface a thorough clean so it’s ready for the coating.
4. Prep the materials. Gather your tools and prepare materials by following manufacturer's instructions closely.
5. Apply coating. According to the instructions, apply coating to the concrete surface.
6. Customize. Proceed to use any necessary stamps, stencils, scoring tools, coloring systems, and anything else required to customize the design of your stone overlay.
7. Seal. Apply sealer to your completed surface. It’s important to add a sealer which will protect it from wear and tear, UV rays, saltwater, and more. Learn more about the importance of sealers.

For example, if you’re creating the look of basalt, you’ll want to choose a variety of darker colors; for the appearance of sandstone, you’ll want to choose a lighter color.

Painting concrete to look like stone

If you’re looking into painting your surface to create a faux stone surface, rather than resurfacing or staining it, it’s important to do thorough research. Using paint to create the look of stone does not look as realistic as concrete resurfacing and/or concrete staining. Read more about why we discourage clients from painting their concrete.

How long does decorative concrete last?

When installed and maintained properly, decorative concrete overlays can last for many years. Durability depends on factors such as surface preparation, weather conditions, traffic levels, and how well the surface is maintained.

How much maintenance is required?

Decorative concrete overlays are relatively low maintenance. Regular cleaning and occasional resealing can help protect the surface from wear, moisture, UV rays, and stains while keeping it looking its best.

Is a decorative concrete overlay made to look like stone cheaper than installing real stone?

In many cases, yes. Decorative concrete overlays can provide the appearance of natural stone at a lower cost than installing real stone, especially when you factor in material and labor expenses.

Can an overlay be installed over cracked concrete?

It depends. Minor cracks can often be repaired before installing an overlay, but concrete with major structural damage or ongoing movement may require more extensive repairs first.

How long does installation take?

Installation timelines vary depending on the size and condition of the surface, as well as the complexity of the design. Many residential projects can be completed within a few days.

Will decorative concrete overlays fade in the sun?

Professional-grade sealers and coatings are designed to resist UV damage and fading. However, like most outdoor surfaces, some color changes may occur over time with prolonged sun exposure. Regular resealing can help preserve the appearance.
