Consider weather-related factors and other factors such as shade, areas exposed to direct sunlight, wind, rain, temperature fluctuations, shelter and other factors that can either accelerate, delay or affect the suitable time in which the surface is safe to walk on.
When in doubt it is usually safe to walk on and apply water on the surface 12 – 16 hours after the pour is complete in most cases as a general rule.
Extremely Hot Dry and /or unstable conditions
Weather-Shielding (Primer Sealing the surface) as soon as the concrete is hard enough to walk on will assist the concretes ability to block out and better endure environmental instability
