DIRECTIONS FOR APPLYING GLATEX* SIDING SHINGLES PLAINTIFF'S EXHIBIT USG-1459 PLEASE OBSERVE THESE PRECAUTIONS: Store the shingles in a perfectly dry place, preferably in a building. If impos sible to store inside, pile bundles of shingles flat on planks at least 4" from the ground, and protect them carefully with a waterproof covering. Moisture getting between the shingles in bundles may cause discoloration. Never apply over wet, frosty, or ice covered walls, or in wet weather. It is recommended when leaving a job at night that the top unfinished course be temporarily flashed with asphalt roofing paper to prevent rain running down behind the shingles before the job is finished. The special face nails furnished with the shingles should be used for all exposed nailing. These shingles are for application on vertical side walls only, and must not be used on roof surfaces. ATTENTION These shingles may develop a temporary con dition known as efflorescence or "bloom" when exposed to such moisture elements as dew, frost or fog. This is merely a surface film and ordinary rains will rinse it off. In areas not exposed to the rain, such as those under porches, wide eaves, etc., rinsing with ordinary water will remove it. It rarely occurs again after a single washing. PREPARATION OF WALLS The wall surfaces to be cov ered should be made as smooth and even as possible. All warped and irregular boards must be firmly nailed in place. If old shingles or clapboards have thick butts and large exposure, it is necessary to apply bevel wood nailing strips running horizontally, or lath of sufficient thickness to bring the surface out in line with the vertical of the wall. These nailing strips should be on 11 " centers. When applying GLATEX Siding over old brick or stone walls, horizontal nailing strips should be similarly spaced. When applying over stucco, the best practice is to remove the old stucco, nailing the siding to the wood sheathing. Where the stucco is in good condition, however, wood nailing strips may be used as for brick walls. To assist in preventing air infiltration and to provide a suit able even surface upon which to nail the shingles, the walls should preferably be covered with a layer of USG Asphalt Felt or similar breather type material before applying the shingles. The use of a vapor barrier as an underlayment is not recommended, as this might permit condensation to occur within the wall. CAUTION: GLATEX should never be applied on metallic surfaces or underlayments such as aluminum foil, either perforated or unperforated, which might cause con densation to occur against the back of the siding. When such a product is used, we cannot assume responsibility for un satisfactory performance of the siding. MOULDING Whenever the use of GLATEX Siding shingles over old siding brings the wall surface out beyond the old door and window frames, new wood moulding should be installed to cover the exposed edges of the siding shingles. Adequate flashing should be used over all window and door openings, and a suitable water table or drip edge provided along the base and under all openings. See detail No. 1 . OUTSIDE AND INSIDE CORNERS Any one of several meth ods of finishing corners may be used. Shingles may be butted against existing corner boards, or new corner boards installed. Bull nose corner bead or individual metal corners are sometimes used. Individual metal corners matching various colors in our siding line are obtainable. Some outside corners are formed by weaving or "lacing" alternate courses of shingles, lining up the side edges of corner shingles at each course with the faces of the two walls alternately, so a single line will not be formed. When this is done, edges should be brought down to a close fit with a rasp. See detail'No. 3. Both inside and outside corners should be flashed with heavy asphalt felt or metal flashing strips to provide a true corner and additional weather protection. See details No. 2 and No. 3 .

OFF. ITTING ANq PUNCHING GLATEX Siding Shingles are ways furnished die cut, with clean, sharp edges. Where is necessary to cut shingles on the job, both for the sake of finished job, and because it is quicker, it is recommended at an asbestos shingle cutter be used. It is in fact almost dispensable. Such shingle cutters with a 27Vi" or 32" blade e regularly provided with a punch for punching nail holes len necessary, and a notching device for cutting irregular apes to fit around window sills. These cutters can be easily tained from our dealers. Where shingle cutters are not available, shingles may * scored with a sharp instrument, and snapped over a aight edge. RST COURSE Apply U" x 1" cant strip or wood furring ip along the bottom of the wall. Snap a level chalk line 11 %" jove the bottom of this cant strip. Shingles in the first course ould be laid with the top edge along this chalk line, thus ;uring a straight level base line, and permitting the shingle overhang the cant strip 'i", forming a proper drip edge, aply a joint strip folded vertically at the corner. See detail o. 2. Start the application of the first course with a full size ingle, extending the butt Vi" below the cant strip to form a ip edge. With the top edge of the shingle on the chalk line;, jply the first and center face nails using the nail,holes at the .ver edge of the shingle. Then insert a joint-strip beneath the Ter end of the shingle, centered under the vertical, joint be- een this shingle and the shingle to be applied adjacent to it, id apply the third face nail through the third nail.hole so as engage the joint strip. ^ Continue application of subsequent' shingles, in a similar anner, placing an asphalt joint strip under., each joint so that e face nail at each end of a shingle engages a-joint strip. It is important in nailing that you nail across the shingle-r, ^ ver nail both ends and then the center^ ' - - ` COND AND SUCCEEDING COURSES Apply a folded nt strip at the corner as in the first course, providing a % " p of the strip over the first course shingles. See detail No. 3. Cut a full size shingle in half to provide for staggered joint application. Always use two holes in the butt of any piece of shingle, punching new holes if necessary. Note: Shingles can be aligned for proper exposure by inserting two colored face nails in the holes at the butt of the shingle allowing the inserted nails to rest upon the top of the underlying shingle. Face nails are then driven as before being careful to insert a joint strip at each vertical joint as before described with the end coming % inch down over the lower course. Continue appli cation with full size shingles, being careful to make tight joints. Complete succeeding courses as described, breaking vertical joints at half shingles in alternating courses. Detail No. 3 APPLICATION OF SUCCEEDING COURSES OVER GYPSUM OR INSULATING SHEATHING Various types of attachment systems are available for the application of siding over these sheathings. GLATEX may be obtained without face nail holes for use with such attachment systems. OVER HIGH DENSITY NAIL BASE INSULATING SHEATHING G.LATEX Siding may be applied directly over this type of Sheathing. Use non-rusting nails of the type specified by the Sheathing manufacturer. OVER PLYWOOD SHEATHING When applying GLATEX siding over plywood sheathing, the use of a 1 Vi-inch long, 0.114 inch diameter shank screw thread aluminum nail is recommended.
