National Gypsum Co. METHODS Interior Applications General - All framing should comply with local building code requirements and be designed to provide support with a maximum allowable deflection of L/360 under all intended loads. Framing members should be spaced a maximum of 16" (400 mm) oc. Cut or score PermaBase on rough side of panel. Install tile and tile setting materials in accordance with current ANSI specifications and Tile Council of North America (TCNA) guidelines. Tile, Thin Brick and Other Facing Materials Installation of tile or similar facing materials should comply with ANSI A108.11 standard specifications. Control Joints - For interior installations, allow a maximum of 30 lineal feet (9 m) between control joints. A control joint must be installed, but is not limited to the following locations: where expansion joints occur in the framing or building (discontinue all cross furring members located behind joint); when boards abut dissimilar materials; where framing material changes; at changes of building shape or structural system; and at each story separation. Place control joints at corners of window and door openings, or follow specifications of architect. Do not fill control joint cavity with coating or other materials. Walls and Ceilings Wall Framing - Continuously support edges of PermaBase parallel to framing. Provide additional blocking when necessary to permit proper PermaBase attachment. Do not install PermaBase directly over protrusions from stud plane, such as heavy brackets or fastener heads. Studs above a shower floor should be either notched or furred to accommodate the thickness of the waterproof membrane or pan. The surround opening for a tub or precast shower receptor should not be more than 1/4" (6.4 mm) larger than unit to be installed. Ceiling Framing - The deflection of the complete ceiling assembly due to dead load (including insulation, PermaBase, bonding material and facing material) should not exceed L/360. The dead load applied to the ceiling frame should not exceed 10 psf (49 kg/m2). The ceiling joist or furring channel should not exceed 16" (406 mm) oc. Edges of PermaBase parallel to framing should be continuously supported. Provide additional blocking when necessary to permit proper PermaBase attachment. PermaBase Cement Board - Apply PermaBase with ends and edges closely butted but not forced together. Stagger end joints in successive courses. Drive fasteners into field of cement board first, working toward ends and edges. Space fasteners maximum 8" (203 mm) oc for walls, 6" (152 mm) oc for ceilings with perimeter fasteners at least 3/8" (9.5 mm) and less than 5/8" (15.9 mm) from ends and edges. Ensure PermaBase is tight to framing. Joint Reinforcement - Trowel bonding material to completely fill the tapered recessed board joints and gaps between each panel. On non-tapered joints, apply a 6" (152 mm) wide, approximately 1/16" (1.6 mm) thick coat of bonding material over entire joint. Immediately embed 2" (51 mm) alkali resistant fiberglass mesh tape fully into applied bonding material and allow to cure. Some bonding material should be applied to corners, control joints, trims or other accessories. Feather bonding material over fasteners to fully conceal. Floors and Counters Subfloor or Base - Securely glue and fasten 5/8" (15.9 mm) exterior grade plywood to floor joists or counter base. For 1/4" (6.4 mm) PermaBase, use 3/4" (19.1 mm) plywood. Floor joists and counter framing should be spaced a maximum of 16" (406 mm) oc. Note - Floor trusses or I-joists may be spaced 19.2" (488 mm) oc with 3/4" (19.1 mm) tongue-and-groove subfloor decking. Underlayment - Using a 1/4" (6.4 mm) square-notched trowel, apply a setting bed of latex-Portland cement mortar or thinset to the subfloor or counter base. Immediately laminate PermaBase to subfloor or base leaving a 1/8" (3.2 mm) space between boards at all joints and corners. Leave a 1/4" (6.4 mm) gap along walls. Stagger joints so they do not line up with underlying substrate joints. Fasten PermaBase every 8" (203 mm) oc throughout board field and around all edges while setting bed mortar is still workable. Around perimeter of each board, locate fasteners 2" (51 mm) from the corners and not less than 3/8" (9.5 mm) from the edges. Fill all joints solid with bonding material. On non-tapered joints, such as butt ends, apply a 6" (152 mm) wide, 1/16" (1.6 mm) thick coat over the entire joint. Embed fiberglass alkali resistant mesh tape fully into applied bonding material and ensure that tape is centered over joint. Apply bonding material over fasteners to fully con-

ceal. Remove all excess bonding material and allow to cure. Exterior Applications General - All framing should comply with local building code requirements and be designed to provide support with a maximum allowable deflection of L/360 under all intended live (including wind) and dead loads. Note - Cut or score PermaBase on rough side of panel. Install tile and tile setting materials in accordance with current ANSI specifications and Tile Council of North America (TCNA) guidelines. Control Joints - For exterior installations, allow a maximum of 15 lineal feet (4.6 m) between control joints. A control joint must be installed, but is not limited to the following locations: where expansion joints occur in the framing or building (discontinue all cross furring members located behind joint); when boards abut dissimilar materials; where framing material changes; at changes of building shape or structural system; and at each story separation. Place control joints at corners of window and door openings, or follow specifications of architect. The control joint cavity must not be filled with any coating or other materials. Decks Subfloor - Securely glue and fasten plywood to floor joists and space a maximum of 16" (406 mm) oc. Subfloor should be sloped at a minimum pitch of 1/4" (6.4 mm) per foot. The floor surface should be true to plane within 1/8" in 10' (3.2 mm in 3 m). Underlayment - Using a 1/4" (6.4 mm) square-notched trowel, apply a setting bed of latex-Portland cement mortar to the subfloor. Immediately laminate PermaBase to subfloor leaving a 1/8" (3.2 mm) space between boards at all joints and corners. Leave a 1/4" (6.4 mm) gap along walls. Stagger joints so they do not line up with underlying substrate joints. Fasten PermaBase every 8" (203 mm) oc throughout board field and around all edges while setting bed mortar is still workable.
