/ <= 6- BETTER WALLS 0ABB ONSTRDCTION fl PERFECT, LOW COST JOINT CONCEALMENT AND REINFORCEMENT BB015 2480 (Cross section of Recessed-Edge Joint finished with Perf-A-Tape and Cement) New Recessed-Edge Sheetrock* offers a new kind of wallboard construction that makes possible stronger, smoother wallboard jobs. The reason is that the unique, patented edges provide a method for building stronger, smoother reinforcement at the joints. The long edges of the face side of Recessed-Edge Sheetrock are depressed. When boards are erected these recessed edges form a shallow channel at the joint. Into this channel special cement is applied and a strong fibrous tape is embedded in the cement (see cross section above). Then the cement is smoothed off straight and even with the face of the board. PerfA-Tape--a strong, fibrous, patented tape--is particu larly designed for use in this patented joint system. With this patented system--Recessed-Edge Sheetrock and Perf-A-Tape--you secure stronger, smoother wallboard construction. That is because the new type of edge of the board, and the new joint treatment, make possible better reinforcement at the point where reinforcement is needed most; make possible hiding the joint reinforcement within the thickness of the board itself, providing a better base for decoration, smooth and without shadow lines at joints. Horizontal or Vertical Application Recessed-Edge Sheetrock--plus the Perf-A-Tape Sys tem of Joint Reinforcement--assures you of joints strong enough for horizontal application of board on side walls and at right angles to ceiling joists. This construction provides increased bracing strength for the building. It promotes better, stronger construction around joints occurring at corners or openings. Recessed-Edge Sheetrock and the Perf-A-Tape Sys tem of Joint Reinforcement may also be applied verti cally, just like regular Sheetrock with square edges. In this type of construction the new Recessed-Edge helps prevent bad joints which might otherwise occur on studs or joists. Recessed-Edge Sheetrock has all other Sheetrock features -- an easily decorated sur face; a fireproof, non-warping, moisture-resistant core. BB015 2481 By finishing walls and ceilings with Recessed-Edge Sheetrock and Perf-ATape, you secure a "one-unit con struction" of superior strength--a construction that will assure longer life and lower upkeep costs in many types of buildings. Developed by Experiments For twenty years, the United States Gypsum Company has been manu facturing Sheetrock. In that time bil lions of feet have been sold in all parts of the country. And since it started manufacturing wallboard, the com pany has constantly worked toward the development of better types of joint treatment. Fills Need Perfectly Sheetrock Perf-A-Tape Joint System-- for use exclusively over Sheetrock-- is the latest and best result of such con tinuous research work. It fills perfectly the need for joint treatment that pro vides these two important features: 1. Effective joint concealment and reinforcement; 2. Low cost. Thoroughly Tested Tests show that Perf-A-Tape over Sheetrock makes the joint as strong as Sheetrock itself. (See photo below.) Perf-A-Tape, the joint system itself, and the joint construction are fully patented by the United States Gypsum Company. Perf-A-Tape is sold as a System of Joint Treatment for use ex clusively over Sheetrock, The Fire proof Wallboard. Conveniently Packaged Perf-A-Tape Joint System comes packed in cartons containing a 250foot roll of Perf-A-Tape, a 17-pound bag of joint cement, and complete directions for applying. Whether board is applied horizontally or vertically, Perf-A-Tape provides the ideal joint treatment for Recessed-Idoe Sheetrock. Tests Show Strength ol Joints Finished with Perf-A-Tape The illustration demonstrates the unusual and almost unbelievable strength of the wallboard joint re inforced with Perf-A-Tape joint treatment. This and many other strength tests made in the United States Gypsum Company's Research Lab oratories prove that Perf-A-Tape joints provide stronger walls. These tests are your assurance that Perf-ATape will help you get better, more permanent wallboard construction. And in actual construction, too, Perf-A-Tape has proved its unusual worth in building with wallboard. The many homes in all parts of the* United States that have been fin ished with Recessed-Fkige Sheet rock and Perf-A-Tape stand as an endorsement of Perf-A-Tape's out standing strength, its unequalled ability in concealing joints. And Perf-A-Tape provides this superior joint concealment and re inforcement without interfering with the smooth decorative surface of Sheetrock. It helps make a better base for any type of interior deco ration--texture paint, casein paint, other flat wall paints, enamel, wall fabrics, wallpaper, etc. BB015 2482 NEW U S 6 METHOD OF DECORATION TEXTONE FOR T E X T U R E - T E X O LIT E FOR COLOR One of the finest ways of decorating walls of RecessedEdge Sheetrock and Perf-A-Tape is to use the rich beauty and distinctiveness of the textured or stippled finish. This type of decoration is being used increas ingly today in many of America's finest homes. And the textures being used are the finer, subtler textures, that give to walls and ceilings little more than a sug gestion of texture, rather than the heavy, very rough effects widely used several years ago. New Method Cuts Cost These finer, simple textures in brighter, more attrac tive colors, can easily be obtained with U S G's New Method of Decoration, at costs much lower than have ever before been possible. A brief description of this New Method of Decoration discloses why this is so. First, white Textone* is applied thinly over the sur face of Sheetrock. Then the desired texture effect is worked into the coat of Textone. The third step is the application of the desired color with Texolite,* the new low cost, easily applied casein wall paint. Both are Quality Products The result is a wall of delicate texture and beautiful permanent color. And it is a job of the highest quality. Textone has long been the product preferred by lead ing decorators for some of the best texture work in the country. And Texolite is becoming the leader because of its unexcelled ability to provide true bril liant color and durability. The reduction in cost of texture work done accord ing to U S G's New Method is in no way a reduction in quality or beauty; it follows simply from a more economical way of using Textone so as to give much greater coverage per pound of material. The thing that makes possible this economy in the amount of Textone used is the excellent hiding power of Texolite, its high light reflection, the soft sheen of its surface, and its natural bond with Textone. Other Types of Decoration If you prefer, you can decorate your Sheetrock walls with any of the other commonly used decorations-- oil paint, wallpaper, canvas, enamel, etc. For flat wall decoration, Texolite is the most economical and effective paint to use. It gives you exceptional bril liance, non-fading color, one-hour drying, and better coverage--one coat hides most backgrounds.
