Pour the paint into a 5-gallon (19-liter) can with an attached side tray; roller trays that you set on the floor spill too easily, are often stepped in, and are difficult to pick up and move without creating a mess [source: Painting and Decorating Concourse].
Gypsum is a latent heat effect material, which during temperature rise undergoes essentially endothermic crystallographic phase transitions that lead to a decrease in heat propagation through the thickness of the board. 2 –4 Those phase transitions are associated with volume variations that generate stress inside the structure.
