278 CORK INSULATION of . . .-inch pure corkboard cut accurately and joints sealed tightly with hot Asphalt cement, the corkboard extending beyond the inside face of the wall so as to join and seal with the wall <strong>insulation</strong>. The <strong>insulation</strong> contractor shall furnish the material required for this purpose, but the installation shall be made by the general contractor. 117.—Miscellaneous Specifications (continued). (43) Rat proofing. As a barrier against rats and mice entering this cold storage room, there shall be installed over all areas of the room and securely stapled in place, with all joints carefully butted or lapped, galvanized wire square-mesh screen, No. 18 gauge, 3 mesh (1/3-inch). The screen shall be located as near as possible to the point of expected attack, that is, the screen shall be laid across ceiling joists and wall studding before the sheathing is applied, fastened to the surface of soft brick or laid down over wôod floor before the first layer of <strong>insulation</strong> is applied, and similarly used elsewhere as required. 117.—Miscellaneous Specifications (continued). (44) Portland cement mortar. ! The Portland cement mortar (not the Portland cement ! plaster) used in connection with the corkboard <strong>insulation</strong> on walls and partitions shall be mixed in the proportion of one ; part Portland cement to two parts clean, sharp sand. The Portland cement mortar used in connection with the corkboard <strong>insulation</strong> on ceilings shall be mixed in the propor- | tion of one part Portland cement to one part clean, sharp sand. (45) Asphalt cement. Note: See specification given in Article 100, under head i ing entitled, ''Specification for Asphalt cement for cold stor- : age <strong>insulation</strong>." i (46) Asphalt primer. Note: See specification given in Article 100, under head- ing entitled, "Asphalt primer for use with Asphalt cement." ' j '
CHAPTER XIV. COMPLETE DIRECTIONS FOR THE PROPER APPLI- CATION OF CORKBOARD INSULATION. 118.—General Instructions and Equipment.—For many years it was considered necessary, or at least highly desirable, that all corkboard surfaces to be erected in Portland cement mortar and all corkboard surfaces to be finished with Port- land cement plaster, should be scored on the side against which the mortar or plaster was specified to be applied. This scoring had to be done at the factory and consisted of several parallel saw grooves running the length of the corkboards, and which were put there as a key or bond for the cement. Experience has demonstrated, however, that the plain surface of corkboard is of such character as to permit an intimate and satisfactory bond with Portland cement, as with Asphalt cement, and score marks are no longer considered essential. The plain corkboard may be scored on the job, if scoring is preferred, before being erected in Portland cement mortar, by roughening the surface slightly with any pronged tool, such as a few wire nails driven through a piece of wood. If it is desired to roughen the surface to receive Portland cement plaster, then the work is done after the corkboard has been put in place and just before the first coat of plaster is applied. The Portland cement mortar, in which corkboard is fre- quently erected to masonry walls, and the like, should be pre- pared by mixing* one part (by volume) of any standard grade of Portland cement with two parts of clean, sharp sand. Be sure the sand is clean, and be sure that it is sharp. It will require 5.0 barrels of Portland cement* and 2.1 cubic yards of *The Portland Cement Association, 33 West Grand Avenue, Chicago, Illinois, with branches in many cities, gladly furnish <strong>complete</strong> data relating to the proper mixing of Portland cement for any purpose.
