About this product
A semi-transparent stain with a long tail: touch dry at 1 hour, tires at 72 hours and full cure at 4 weeks. An older 11/2016 sheet gives different traffic times.
Using this specific product
BEHR Premium Semi-Transparent Concrete Stain 850 is listed here as the Water-based concrete stain version for concrete patios, driveways, and garage floors. For repairing concrete or masonry, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says Water-based concrete stain; related versions can use different timing.
- For concrete patios, driveways, and garage floors, pay particular attention to substrate moisture, depth, temperature and protection from traffic.
- At 77°F (25°C) and 50% relative humidity. The source gives no conditions for this time.
How to check readiness
Check the slowest, coolest section before loading or coating. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required. Open the area gradually and keep heavy or hot tires off until the full stated milestone.
Avoid this mistake
Early strength, coating readiness and full cure are separate decisions.
