T2 Blue is termite resistant and can resist the effects of weather for short periods, typical of normal construction environments and timescales. It is not designed to resist decay causing fungi and should be stored in dry conditions wherever possible. After delivery and prior to use, T2 Blue should ideally be protected from moisture by covering with a waterproof membrane and storing above the ground. Following the use of T2 Blue, the roof covering of the building is required to be completed as soon as possible to provide weather protection and protection from decay. Exposure for long periods may cause decay, negating the termite resistance of the product.
