What should the temperature be to install pool liner?

The ideal temperature for installing a pool liner is typically between 65°F and 85°F (18°C to 29°C). Installing the liner in temperatures below 65°F can make the material less pliable and more difficult to work with, potentially leading to wrinkles or improper fitting. Conversely, extremely high temperatures can cause the liner to become too stretchy and may result in damage. Always check the manufacturer's guidelines for specific recommendations.
