Got Check Cracks? Check Wind Speed.
In December 2023, the National Plasterers Council released Technical Bulletin No. 8, highlighting the impacts of wind speed on plastic shrinkage, or check cracks, in pool plastering. While the harmful effects of hot temperatures, low humidity, high winds or a combination of these are known, the study underlines wind speed as the dominant variable. The NPC says the findings are crucial for reducing check cracks and improving plaster durability.
