This specification covers the minimum requirements for bonding compounds used in adhering interior gypsum plasters to structurally sound surfaces. The bonding compound should be a tinted film-forming material suitable for application by brush, roller, and spray. It shall have a non-oxidizing, non-toxic, and non-flammable composition, and have a smooth, homogeneous, and flexible consistency with no settling of the solids. It shall also be free of foreign matter, and shall not be noticeably affected by mild acid or alkali. The apparatus needed for the preparation of the compound are moist cabinet, forced drift type oven, freezer, balance, timing device, tamper, steel straight edge, metal-bladed spatula, paint brush, briquet testing machine, briquet molds, divider, and clips. Specimens shall be sampled, tested, and conform accordingly to the following performance requirements: bonding capability; degradation; high temperature stability; freeze-thaw stability, and bond strength.

This standard is referenced in the 2012 International Building Code® and the International Residential Code®.
