11.23.0 Plaster Systems For years, the three-coat plaster system installed on expanded metal lath, attached to either wood or metal furring or studs, provided the ultimate in interior wall and ceiling construction. The smooth monolithic system created by plastering provided a relatively abuse-resistant surface; when decorative cornice or ceiling moldings were applied, an elegant room took shape. However, the skills required to properly apply a three-coat plaster wall and their associated costs brought forth the development of veneer plaster systems in the 1960s. These systems took advantage of the large gypsum panels available to provide a smooth, stable foundation for a 1⁄16 inch (3 mm) to 1⁄8 inch (6 mm) application of plaster. The overall cost of this system is considerably lower than the conventional scratch-brown finish coat. With a drying tie of 48 hours versus 5 days for the regular three-coat system, production is greatly increased.

11.24.0 Five Levels of Drywall-Taping Systems • Level 1 All joints and interior angles shall have tape embedded in joint compound. The surface shall be free of excess joint compound. Tool marks and ridges are acceptable. Suggested location of Level 1 taping: fire- and smoke-taped baffles above suspended ceilings and elsewhere where gypsum board is concealed from public view. • Level 2 All joints and interior angles shall have tape embedded in the joint compound and shall receive one separate coat of joint compound applied over all joints, angles, and fastener heads and accessories. The surface shall be free of excess joint compound. Tool marks and ridges are acceptable. Suggested location of Level 2 taping: Substrates that receive tile or paneling in excess of 1 ⁄4 inch (8 mm) thickness. • Level 3 All joints and interior angles shall have tape embedded in the joint compound and shall receive two separate coats of joint compound applied over all joints, angles, fastener heads, and accessories. The surface shall be free of excess joint compound and all surfaces shall be smooth and free of tool marks and ridges. Suggested location of Level 3 taping: Areas scheduled to receive heavy-textured finishes (hand or spray applied), paneling less than 1⁄4 inch (8 mm) thickness, or Class III vinyl wall coverings. • Level 4 All joints and interior angles shall have tape embedded in the joint compound and shall receive three separate coats of joint compound applied over all joints, angles, fastener heads, and accessories. Surfaces shall be free of excess joint compound and all surfaces shall be free of tool marks and ridges. Suggested location of Level 4 taping: Areas to receive paint coatings, paneling less than 1⁄4 inch (8 mm) thickness, and where vinyl or wall fabric wall coverings will be applied. • Level 5 All joints and interior angles shall have tape embedded in the joint compound and shall receive three separate coats of joint compound applied over all joints, angles, fastener heads, and accessories. Provide a thin skim coat of joint compound (or other material manufactured expressly for this purpose) over the entire surface. The finished surface shall be free of excess joint compound and all surfaces shall be smooth of tool marks and ridges. Suggested location of Level 5 taping: Areas scheduled to be lit by cove- and washing-type light fixtures.
