Does Your External Masonry Paint Have A Minimum Temperature For Use?
Masonry paint should not be applied to surfaces when the ambient temperature (or substrate temperature) is below 5 degrees and not higher than 25 degrees. The paint coating should be protected from rain for minimum 48 hours after coating so do not paint if there is a risk of rain during this period.
Avoid painting in full sun or on warm surfaces. For best results, always attempt to time the painting of a given elevation prior to exposure to direct sunlight.
