The working temperature can significantly affect epoxy flooring projects. Epoxy products should ideally be applied between 20-25°C but may be used between 10-30°C. Higher temperatures cause the epoxy to cure quicker, lowering viscosity but reducing working life, while lower temperatures extend working life but can cause issues like blushing and poor leveling due to higher humidity. Tips for different temperatures include pre-heating or cooling areas, keeping products at room temperature, and adjusting mixtures.
