Concrete Stain Project Scheduling and Drying Times

Drying time (final coat) 10 hours minimum to 24 hours or more in colder weather or more humid weather. Allowing to cure 48 to 72 hours is best, especially in cooler weather. Allowing to cure 48 to 72 hours is best, especially in cooler weather.

Understanding and Mitigating Moisture Issues in Concrete

Newly placed concrete slabs can require as long as four weeks of curing time per inch of slab thickness just to evaporate the excess water used during placement. This does not include any residual moisture contained in backfill or sub-grade materials. These conditions can greatly impact on-time completion of Fast Track construction projects.

CCANZ Hot and Cold Weather Concreting

The prime effects of low temperature on freshly placed concrete are A decrease in the rate at which the concrete sets and gains strength, with a resultant increase in the time taken to finish the concrete; (at temperatures below freezing) physical damage to the concrete in the form of surface scaling or bursting, and the cessation of hydration.

First, time to initial set is lengthened, requiring longer days for finishing crews, which could result in cost overruns. Second, freshly mixed concrete freezes at 29 degrees Fahrenheit (-2 degrees Celsius), and early freezing permanently damages concrete, making it less durable, weaker and possibly unstable.

The incorporation of supplementary cementitious materials in concrete mixes, such as GGBS, seem to reduce/control the high early age temperature rise in concrete but they also have significant effects on its thermal and,generally, early-age properties which simultaneously vary with time and temperature, where limited knowledge exists.

What Precautions Should You Take When Pouring Concrete in

The colder the surrounding air temperature is, the more difficult it is to maintain a stable concrete temperature. The temperature of the subgrade should be as close to the temperature of concrete that is being poured. Once the concrete is poured, a liquid curing compound can be sprayed over the concrete, and protected with an insulated blanket.

When Cold Temperatures Affect Sealers Concrete Decor

When temperatures are low, the more sealer on a concrete surface, the longer it takes to cure and the more time available for cold-weather issues to take place. Not that we want to rush the curing process, but when temperatures are cool, we do want to help the sealer cure as efficiently as possible.
