' 1-:Mr*r-*.' t beat iful way to contr M sound acoustical plaster (s r ( 'N 1a AUDICOTE Acoustical Plastar requires only the addi tion of water to produce a plaster that may be band- or machine applied (preferred). Since AUDICOTE does not set into a danse, hard mass, but simply dries to form a porous surface, it develops superior sound-absorption properties. Basically mineral in composition, it will not support combustion. If spray painted according to U.S.G. specifications, its sound-absorption qualities will not be appreciably affected. AUDICOTE is readily adaptable to various finishing methods, tinting and incorporation of special aggre gates to further Increase the design and decorative possibilities. Variety can also be obtained through varia tion of texturing technique. Many unusual and unique effects can be created by impressing designs into the surface. Inexpensive "glitter*' aggregates in the final coat lend a subtle touch of "starlight" to any room. whERE TO USE FT... AUDICOTE is recommended for use on ceilings or wall areas not subject to contact or abuse, excessive vibra tion or high moisture. It is ideal for use in classrooms. churches, offices, auditoriums, theaters, libraries, hos pitals; In short, wherever beautiful, sound-aosorbent. fireproof surfaces are desired. AUDICOTE lends itself perfectly to curving contours and smoothly sweeping surfaces. The uniformity of textures resulting from spray applications make this product particularly suitable for *.. use on large, unbroken expanses of ceiling. AUDICOTE Plaster's exceptional bonding characteris tics allow it to be applied over IMPERIAL* Basecoat Plaster, or regular gypsum baaecost, Portland cement bcseeoata, monolithic concrete and fabricated concrete units. why YOU should use nv.r AUDICOTE Acoustical Plaster broadens the horizon In the field of sound control.

F H. 0*1. dlRECTioNS HAND APPLICATION'--Apply the first coat by firmly scratching in to approx. vt thickness and immediately coupling back to full thickness. Leave mis coat smooth and level tor application of the finish coat. Apply the finish coal over the partially dry first coat by scratch* ing in and immediately doubling back to a Vi " thickness. After the finish coal has taken up sufficiently. It may be stippled, stipplo-perforated, floated,darbied or trowelled to produce the desired finish._ .' MACHINE APPLICATION--Apply first cost to s lull 7/16" thickness and level to a true, smooth surface. Apply the second coat over the partially dry first coat to t H' thickness, using pump pressure, air pressure, nozzle adjustment and the amount of water necessary to give the required spray texture. On low-suction bases such as monolithic concrete, three-coat application may be necessary. Allow first coat to dry completely to provide suction for succeed ing coats. Caution--Allow AUDICOTE Acoustica/ Plaster to dry naturally, furnishing proper heat and ventilation in alow drying weather. Avoid-test or uneven drying which may result in excessive assuring. Large fixtures should be ailed end leveled prior to application ot the hnish coat. PAINTING AUDICOTE ACOUSTICAL PLASTER Use a vacuum cleaner with hose and brush attachment to remove all loose dirt or dusL For first coat, mix one part TEXOLITE Standard Paint to one part water by volume. For second coat, if required, mix one part paint to two parts water by volume. Spray-apply paint using sufficient nozzle pressure and proper application technique to insure uniform coverage of the surface of AUDICOTE Plaster. Allow at least over night drying between coats. Under slow drying condi tions. additional drying time mey be necessary. SpECificATioNS The following short form specification may be used In the general plastering specifications. GENERAL PROVISIONS General provisions for plastering apply to acoustical plaster application. SCOPE As indicated on drawings, all walls and ceilings shall be finished as herein described.
