Warnings

  • If the ambient temperature is below 40°F or above 90°F, you should probably wait for better temperatures. However, use of a curing compound can help if temperatures are too warm. Try finding a compound that will dry clear so it will not stain the surface. This type of compound may appear pink in color. But don't worry, it will disappear once dry. If the temperature is expected to drop below 45°F use of a concrete blanket is advised or any kind of covering that can hold the heat from the concrete in. This should be maintained for 120 hours.
