The color-rich, low-gloss finish is what puts the AR350 at the top of this list. On stamped concrete, the solvent acrylic darkens the surface just enough to bring out the pattern and the color, then dries to a soft sheen rather than a mirror. That is the look most stamped patios want: richer, but not plastic. We also like that the finish is non-yellowing, which matters on light gray or colored concrete.
The 5-gallon pail is built for a full patio. The stated coverage is 175 to 225 square feet per gallon, so a single pail gives you a realistic chance at two coats on a typical stamped patio, though deep joints and a porous surface will pull you toward the low end. It rolls or sprays on and is self-priming, so the job is mostly about cleaning, drying, and keeping a wet edge.
What keeps it from being the right pick for everyone is the finish: it is firmly low gloss, not a high-shine wet look. If you want the patio to gleam, the AR500 is the better match. For most stamped patios, though, the AR350 is the safest balance of color, coverage, and a finish that does not call attention to itself.
What We Like
- Deepens color on stamped concrete
- Low-gloss wet look stays subtle
- Five-gallon pail suits full patios
- Self-priming and sprayable
Worth Noting
- Strong solvent odor during application
We recommend the AR350 as the default for stamped concrete: it deepens color with a low-gloss wet look and covers large patios without a mirror finish.
