A method of preparation and use of high-strength gypsum wallboard, as well as a core composition suitable for use therein, are disclosed. The core composition includes a slurry of calcium sulfate hemihydrate (stucco), water, and a strengthening agent. The strengthening agent includes an acrylic polymer composition having a glass transition temperature of about 15 DEG C. or greater, and preferably has good divalent ion stability. The method provides wallboard having increased core strength, paper-to-core bonding, and strength-to-weight ratio.
