To assist with post-hurricane rebuilding efforts, the Gypsum Association, a not-for-profit trade association founded in 1930, has placed all relevant technical documents pertaining to gypsum board (AKA drywall or wallboard) on a single, easy to locate webpage along with answers to frequently asked questions associated with repair and replacement after water damage.

These technical resources lay out proper methods of handling, storage, repair, and replacement of gypsum board. As always, consumers, building professionals, code officials, inspectors, and building product distributors can access these technical resources online and free of charge.

Technical documents essential to appropriate repair of flood damaged properties are:

  • GA-231-2015 Assessing Water Damage to Gypsum Board
  • GA-235-2017 Gypsum Board Typical Mechanical and Physical Properties
  • GA-238-2016 Guidelines for Prevention of Mold Growth on Gypsum Board
  • GA-801-2017 Handling and Storage of Gypsum Panel Products
  • GA-1000-2017 Identification of Gypsum Board

The Gypsum Association's members comprise all the active gypsum panel product manufacturers in the United States and Canada. To be eligible for membership, a firm or corporation must calcine gypsum and manufacture gypsum board under the provisions of ASTM C1396 Standard Specification for Gypsum Board.

Only panels made to this high standard are code compliant in the United States. This standard also mandates that each panel is labeled legibly on the back surface of each board, parallel to the bound edge of the board. GA-1000-2017 Identification of Gypsum Board provides important information related to ensuring gypsum panels are compliant with ASTM C1396.
