DIRECTIONS FOR APPLYING GiATEX* SIDING SHINGLES 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 /eaving 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 II" 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 wails. 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 underlaymenrs 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 wail surface out beyond the old door and window frames, new wooa moulding should T.M. REG. U.S. PAT. OFF. be installed to cover the exposed edges of the siding shingles. Adequate flashing should be usea over all window and door openings, and a suitable water table or drip edge provided along tne base ana 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 sinqle line will not be formed. When this is done, edges should be brought down to a close ft 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 .

Where is necessary to cut shingles on tne job, both for the sake of a finished job, and because it is quicker, it is recommended that an asoesros sningle cutter be used, it is in fact almost indispensable. Such shingle cutters with a 271/2 " or 32" blade are reguiarlv provided with a punch for punching nail holes when necessary, ana a notching device for cutting irregular shapes to fit around window sills. These cutters can be easily obtained from our dealers. Where shingle cutters are not available, shingles may be scored with a snaro instrument, ana snapped over a straight edge. rIRST COURSE Aaply x 1" cant strip or wood furring strio along the bottom of the wall. Snap a level chalk line 11 Vi" aoove the bottom of this cant strip. Shingies in the first course snould be iaid wirh the too edge along this chaik line, thus nsurina a straignt levei base line, ana permitting the shingle to overhang the cant strip a forming a proper drip edge. Apply a loint strip folded vertically at the corner. See detail No. 2. Start the application of the first course with a full size smngie, extending the butt A" below the cant strip to form a arip edge. With the top edge of the shingle on the chalk line, apply the first and center face nails using the nail holes at the lower edge of the shingle. Then insert a joint strip beneath the other end of the shingle, centered under the vertical joint be tween this shingle and the shingle to be applied adjacent to it, and apply the third face nail througn the third nail hole so as to engage the joint strip. Continue application of subsequent shingles in a similar manner, placing an asphalt joint strip under each joint so that the face nail at each ena of a shingle engages a joint strip. It is imoortant in nailing that you nail across the shingle -- never naii both ends and then the center. SECOND AND SUCCEEDING COURSES Apply a folded joint strip at the corner as in the first course, providing a % " lap of the strip over the first course shingles. See detail No. 3. Cut a full size shingle in half to provide for staggerea joint application. Always use two holes in the butt ot any piece of shingle, puncning new holes if necessary. Note: Shingles can be aligned for proper exposure by inserting two colored face naiis in tne holes at the butt of the shingie allowing the inserted nails to rest upon the top of the unaerlying shingle. Face nails are then driven as before being careful to insert a joint strip at eacn vertical joint as before described with the end coming V 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 GLATEX Siding mav 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. -"ce memoas cno ccnaitrons ot cooiication ona use ore oevona our control The Unnea Stores Gvosum Comoonr viii net oe resoonsioie *cr 'enure ot ns proauers wrten nor useo cccsrctng tc ;ur cirec'icnj enc socciticonons UNITED STATES GYPSUM the greatest name in building Gypsum * Lime * Steel * Insulation * Roofing Paint a CD o i\J at ACR-13 Rev. 12 63 Printed m U.S.A. *T.M.
