You are missing opportunities if you are not up-to-date on PLASTER TODAY his is a special issue of Red Topics magazine designed to be more of value to users of lath and plaster than to those who sell these products and services. As you read the record of recent developments and refinements, the ver satility of plaster becomes strikingly apparent. State a structural problem; then reach into lath and plaster's bag of tricks to select the proper solution. It is always there. This issue limits itself to five special areas of building prob lems. It shows (page 3) what can be done with plaster to gain more than ordinary beauty in a plastering job. Plaster literally releases the bonds on a creative architect. It can be shaped, it can be perforated, it can be the base for embed ding decorative objects, it can be smooth, it can be textured. New methods have introduced the work of plasterers into the basic structure of exterior curtain walls. An oppor tunity to escape the me-too sameness of glass and metal exteriors is found in the more flexible choice of texture and form offered by the plastering contractor (page 7). Monumental public buildings for living, learning, work, or for public gatherings--have special problems for which a series of lath and plaster partition systems have been developed (page 11). If you need normal fire protection or exceptional fire pro tection, there are plaster types and methods that give you either, with maximum economy (page 14). The largest segment of building is still private homes. Lath and plaster has much to offer those who would build a home, and in this issue we cover plaster possibilities in both subdivision house and custom-built home (page 13). This special issue, then, is designed to compile the industry's best and most advanced methods in a form that will make it easy for readers to take advantage of all that is offered by "Plaster Today." Extra copies are available to lathing and plastering con tractors to use as their own selling literature with architects, builders and consumers. Address request to Editor, Red Topics, 300 W. Adams St., Chicago 6, III. ath and plaster gives freedom to the creative talent of architects and L designers. It loosens the visual straight-jacket of flat planes and sharp corners, and makes it possible to reproduce in three dimensions any curve, any contour, any shape they can draw. Lath and plaster can supply the variety of contrast in texture upon which many rooms or buildings depend for visual character. It can be smooth and exceedingly hard. It can be as textured as a bubbling bed of lava. It can embrace rocks or pebbles or shells or straw or any other small objects that can give a surface texture. A pattern or design can be pressed into its surface. The possibilities shown here are not a pattern to follow, but a springboard for thought from which the individual designer or architect may launch his own creative ventures. continued BB011 02B7 SWEEPING COMPLEX CURVES HAGGERTY'S, SANTA ANA, CALIF. 3 NATURAL ROCK BEAUTY IN PLASTER BULLOCK'S, SANTA ANA, CALIF.

Now the plasterer can provide an entire exterior curtain wall for a structure of any size. The plastering machine and the power trowel are latter-day developments which make this possible and practical. Plaster also provides fire protection, structural strength, sound and thermal insulation as a back-up material for the metal skin type exterior curtain wall. continued PLASTER TODAY B FOR FINE EXTERIORS I B B O ll 0291 GLASS BEADS IN STUCCO public library, flossmoor, ill. Stucco exteriors offer a variety of surface treatment selections. The sequence (above) of achieving this sparkling exterior wall is first to floatin an inch of port!and cement stucco, stopping about V* inch below the face of expansion strips. The final inch is then troweled in and raked rapidly, and glass particles mixed with wetting agent are sprayed into stucco before it can dry with a hand-held acoustical plaster gun (see photos). The job is worked a panel at a time, with a man on the scaffold and a man on the ground, so toois can be handed from one to other to make the work a continuous process. ARCHITECTS: MacPHERSON.

Curtain walls on monumental apartment project are stucco applied over metal lath tied to steel studs. The building framework of this three* story structure is exceedingly light. Pipe-type columns and junior beams support floor and roof slabs. Plasterers applied a light cream and deep tan integral-colored Oriental stucco to give building exterior color interest, and raked certain panels of the stucco for permanent texture.

The visual effectiveness of a home interior is as dependent upon plasterperfect walls as exterior attractiveness is upon good landscaping. Wall and ceiling areas are such a major propor tion of the visible part of a house that appearance is of supreme importance. For that "little bit better" treatment, handsome textured work is easy to achieve. A spray coat of Audicote acoustical plaster is the source of a finish texture that wins the admiration of all who see it. And the material's acoustical properties absorb household noise, especially in kitchen or laundry.
