Effect of atmospheric conditions on plaster

At the time of plastering or setting, the prevailing weather during periods of drying and hardening can affect the finished work as follows:

1. Frost

The destructive effect of frost on plaster work is significant. Unless special precautions are taken, plastering work will be completely suspended during frosty weather.

2. Cool

A decrease in atmospheric temperature significantly prolongs the setting and hardening time of all plasters. Where plastering is to be done in cold weather, the time interval should be increased to allow for this, and the work should be programmed or reprogrammed accordingly.

3. Condensation

In some areas, cold winter conditions can result in condensation being so high that the finished plaster can spoil the work. This can prevent or prevent wet building operations from drying out for weeks, or even months, thus rendering conditions unsuitable for plastering.

4. Extremely dry conditions

In hot dry conditions the applied plaster may dry out before the setting process is sufficiently advanced. A partially set weak material often has a powdery surface that will not provide a satisfactory base for subsequent coats or decorations. Cemented plasters are particularly sensitive in this regard. In such contingencies the surface should be kept wet continuously during the curing period.
