Plaster-based compounds may not be able to set properly due to summer temperatures. To change plaster from plaster to gypsum (which is the process of setting), plaster-based compounds need a certain amount of water. It may have been drying on the wall for up to 80 minutes before the 90-minute set compound begins to set. Hot weather can cause water loss that is so great that plaster will not revert to gypsum if it doesn't have enough water. This causes weak joints. This can lead to joints cracking, tape falling out, and poor bonding for subsequent compound coats. To fixing this you can use GIB stopping Auckland.
