Plaster based products are not recommended for conditions where they are likely to be located externally or in any way subjected to weathering or excessive dampness.
Absorption of moisture can result in changes to physical properties, including a reduction in the set strength of plasters and also a lengthening of setting time. Gypsum minerals can be affected by absorption of moisture and may change physical properties.
