Can Concrete Be Sealed in the Winter?

Although Murfreesboro has moderate winters, concrete installers still exercise caution when sealing concrete. All concrete sealers have an MFT, which is the minimum film-forming temperature. This means that, if applied to a concrete driveway below this temperature, the sealer film won’t adhere properly. When this occurs, the surface develops delamination, white dusting, and white hazing. A general rule of thumb is to seal concrete only when the ambient air temperature and surface temperature are at least 50 degrees Fahrenheit. However, there are always exceptions.

Some concrete sealers use solvents that cure faster than others. This means that they are less likely to be adversely affected by cold temperatures. For example, water-based solvents are best used during the summertime, while acetone-based solvents are arguably the best ones to use during colder weather. Another consideration is the method of application. Concrete installers will usually spray on the sealer, rather than roll it on when the weather is chilly. Spraying sealer will allow for a more even, thinner coat that will cure more quickly.
