In one aspect, a gypsum panel includes a gypsum core, a fiberglass mat, and a wetting agent deposited across an entire thickness of the fiberglass mat. The wetting agent is deposited onto the first fiberglass mat in an uncoated state of the fiberglass mat such that the wetting agent penetrates the entire thickness of the fiberglass mat.

A slurry for manufacturing gypsum board is disclosed. The slurry comprises calcined gypsum, water, a foaming agent, and a thickening agent. The thickening agent of the present disclosure acts to improve the cohesiveness of the slurry without adversely affecting the setting time of the slurry, the paper-to-core bond (wet and dry), or the head of the slurry by acting as a defoaming agent or coalescing agent. Examples of suitable thickening agents include cellulose ether and co-polymers containing varying degrees of polyacrylamide and acrylic acid. A gypsum board and method of forming the slurry and the gypsum board are also disclosed. The gypsum board comprises a gypsum layer formed from the slurry.
