How to make concrete dry faster in cold weather? Use heaters or heated blankets to thaw surfaces where concrete will be poured. Pouring concrete on frozen ground will quickly cool concrete well below ideal temperatures. Using a heater to prep surfaces will prevent too-quick cooling or freezing and help keep the necessary reactions going.
How long does concrete take to dry in cold weather? Curing time can be based on use. For projects that will carry earlier or heavier loads, the concrete temperature should remain at least 50° F for up to 20 days to be able to handle the eventual structure. In comparison, concrete not exposed to cold weather can cure in as little as one day.
Does concrete cure in cold weather? Concrete can successfully placed, finished, and cured in cold weather or during the winter, but it requires an understanding of the impact of cold weather on the process of creating long-lasting concrete. Fresh and newly-hardened concrete both lose moisture and heat rapidly in cold-weather conditions.
How cold is too cold for new concrete? Experts agree—the best temperature to pour concrete is between 40° – 60°F. When temperatures dip below 40°F, the chemical reactions that strengthen concrete slow down and can lead to weaker concrete.

What kind of paint to use on concrete wall?
Masonry paint (also called elastomeric paint or elastomeric wall coating) is a good choice for concrete painting because it contains binders that contract and expand with the concrete. Exterior house paint can crack and peel on concrete.
How to compute volume of concrete?

What sanding grit for concrete mastic?
