Gray is the safest color decision you can make on an exterior slab and the hardest one to make interesting. The projects below are the ones that got it right, and almost all of them share a trick: they use two or three grays rather than one. The family runs 415 Gray, 424 Silver Gray, 531 Eagle Gray, 417 Light Charcoal, and 406 Charcoal, all stocked across Antiquing™, Portico™, EasyTint™, and AcquaTint™.
This gallery covers outdoor surfaces. For interior floors — basements, kitchens, sunrooms, and commercial spaces in AcquaTint™ and Vibrance™ Dye — see Gray Concrete Floors: Interior Project Gallery.

Hand-poured 36-inch concrete squares stamped and stained in Silver Gray Antiquing™ to read as slate.
A new-build farmhouse patio in Silver Gray
Broom-finished concrete on a new construction farmhouse. Nothing was wrong with it — it was simply the flat, raw gray that fresh concrete always is. Silver Gray Antiquing™ gives it depth without changing the color family.




Hand-poured squares that read as slate
The most ambitious project here. The owner poured thirty-six-inch concrete squares one at a time, stamped each one, and stained them in Silver Gray Antiquing™ so the finished patio reads as slate rather than as concrete. Sprayed on, then EasySeal™ rolled over the top with a nap roller.




A couple in their mid-50s and a stack of contractor quotes
No previous experience, an outdated patio, and quotes they did not want to pay. They worked from the online guides and the how-to videos and saved thousands. Their three takeaways: preparation decides everything, wait for the right weather, and call support when you are unsure rather than guessing.


Hand-painting a natural stone firepit
A natural stone firepit, not concrete — and the contractor estimates to redo it were high enough that the owner scrubbed it down and hand-painted every stone individually in a mix of Charcoal, Gray, Light Charcoal, Silver Gray, and Tweed, then sealed it satin. Five colors across a small surface is what stops it looking painted.






A $4,000 quote turned into a $1,000 weekend
An outdoor BBQ and dining area, quoted at around $4,000. Instead the owner laid pavers and hand-stained each one with a sponge brush in Silver Gray, Tweed, and Charcoal, then sealed. Final cost under a thousand — and the difference went on a trip to the White Mountains.






The completed patio, sealed.
Pool decks in gray
Two approaches to the same problem. The first is a stamped deck in Eagle Gray, Antiquing™ under two coats of EasySeal™. The second is a swirl-finish deck that had gone blotchy — the kind of staining a pressure washer will not fix — evened out with Gray EasyTint™. On a blotchy surface, two coats is the minimum; one coat will follow the blotches rather than hide them.




Extending a patio and matching the old to the new
A patio extension, which is always the harder version of this job because you have to make new concrete and old concrete agree. Gray EasyTint™ over both. The applicator note from this one is specific and worth having: use a cone tip rather than a fan tip, and back-roll what you spray.



The extension where it meets the brick.
Driveways in gray
A tired, damaged driveway in Gray EasyTint™. Worth being straight about what tinted sealer does and does not do here: it will not hide spalling or cracks, but it evens out the color enough that the damage stops being the first thing you see.





A stamped driveway and porch
The front of the house, which is where a gray stain earns its keep — it reads as deliberate rather than as weathered concrete, and the sealer over it takes the weather instead of the slab.


Gray indoors
Everything above is exterior. Indoors the products change to a water-based colored sealer or an acetone dye, and the gray names change with them — Stormy Gray and Light Slate in the dye line, Silver Gray and Light Charcoal in AcquaTint™. All of that is in Gray Concrete Floors: Interior Project Gallery.
