Optimal air temperature for installation of a Rust-Oleum garage floor coating is 55-90 degrees Fahrehheit, and the floor temperature should fall within the following ranges:
• For Rust-Oleum Concrete and Garage: 50-90° (10-32°C)
• For EpoxyShield: 60-85°F (15-29°C)
• For RockSolid: 40-90°F (3-32°C)
If it’s colder, the coating may take longer to cure. The concrete surface must also be completely dry at the time you apply a coating to that it properly adheres. Do not use concrete coating once the concrete and air temperature is steadily below 55 degrees.
If applying to recently poured concrete, allow the concrete to cure for at least 28 days prior to coating.
