Exterior Sheathings: The Dryvit Sprint system can be applied to unpainted wood -based sheathings and to mirrimum 1l2-+nch-thiGk water- resistant carp gypsum sheaving. The sheathing mast be installed (fl accordance with the code. The Sprint system may then be mechanically attached as described in Section it G 2 for ►rload framing or adhesively attached as follows: The adhesive is applied to the back side of the insulation board and spread over the entire surface with a -notched trowel which produces a 1/4 -inch -wide by 3/8 -inch -deep notch every 11 inches. The beard i immediately pressed on to the substrate, slid into place and set. In addi- tion di - tion to the adhesive, a minimum of eight mechanical fasteners and wash- ers as described in Section 11 B 3 are required for each 48 -Inch -wide b -inch-long insulation board. The have coat, reinforcing mesh, and fin- ish � i h coat are then applied as described for open -wood framing in Section 11 C L 4.

General: Allowable transverse wird pressures based on systems installed in accordance with this report, are set forth in this section. Design of the wood and steel framing must also be consid- ered. Maximum a4lowable deflection of structural wall components is 11240 of spay. 2. 1Nafltl Framing: When the system is applied to open -wood framing or wood -based sheathings an framing as described in Section 11 C, a posi- tive wind pressure tip to 40 pounds per square foot and negative pressure up to 26 pounds per square float is allowed. 3. Steel Framing: When the system is applied to minimum No. 18 gage (0.0478) open -steed framing or solid sheathing on framing as described in Section I! C, a positive wind pressure up #0 51 pounds per square foot and negative pressure up to 26 pounds per square foot is ailovred. 4, Concrete Or Concrete Masonry: Allowable cable wi rid pressure for the system adhesively applied to concrete or concrete masonry walls a described ire Section I I C 4 is 26 pounds per sq u'are foot positive or n- tiVe.
