摘要：
A method comprising adding a suspension of a hydrophobic substance to a gypsum slurry. The hydrophobic substance may impart water repellent characteristics to the gypsum, may be used as a foaming aid, density reducer, dimension stabilizer, and others, and may increase the mechanical strength and durability of the gypsum product. In another embodiment of the present invention, suspensions of other substances may be used in addition to or in place of the hydrophobic substance to impart these characteristics.
