What Is the Ideal Temperature for Staining Concrete?
Concrete staining is a technique used to add color to polished concrete floors, counter tops, porches and other concrete surfaces. This type of look is modern and industrial, but can be made warmer and homier by the addition of a colored stain and sealant.
Water Based Concrete Stains
The ideal temperature for applying water-based concrete stain is 70 degrees Fahrenheit. You can apply the stain in temperatures as low as 45 degrees, but lower temperatures can cause slower drying time. The temperature can be as high as 90 degrees for stain application, but higher temperatures can prevent the stain from penetrating the concrete well.
Acid-Based Concrete Stains
Acid-based concrete stain should be applied when the concrete temperature is between 59 and 70 degrees Fahrenheit. The staining process will experience similar issues to water-based stains if the temperature is too high or too low.
Other Environmental Factors
High humidity can slow the drying time for concrete stains significantly. Windy conditions can cause the stain to dry too quickly and not penetrate the concrete well. Make sure the concrete is thoroughly cleaned and dried before staining and allow the work to cure for 24 to 48 hours before sealing.
