This week the cold weather warming had been in force for more than two days. Remember to put on your jackets and stay yourself warm. In fact, many construction chemicals, like the human, are sensitive to cold weather. Most building chemicals have an application temperature range. Take our ARDEX WPM300 rooftop waterproofing liquid membrane as an example, its application temperature range is 10 – 35°C. If the surface temperature is beyond the lower limit (<10°C), the chemical may crease to cure until the temperature is within the application range.
