They are architecturally adaptable to intricate ceiling designs, and can be used equally effective on curved or flat surfaces. While these plasters perform the common function of absorb ing sound and providing a decorative finish, caclf has certain characteristics which influence their individual selection.

AUOICOTE* Acoustical Plaster AUDICOTE Machin*Texturad Finish .rt> w aft DESCRIPTION DESCRIPTION Hi-Lite Acoustical Plaster is a pure white acoustical material, with excellent light reflective characteristics, making it par ticularly adaptable for use in schools and office buildings where light reflectance and efficiency of illumination are important considerations. Its relatively high moisture resist ance makes it an excellent choice for acoustical treatment in naiatoriums and other areas in which high humidities are anticipated. Hi-Lite Acoustical Plaster is not subject to the migration of rust stains from the construction over which it is applied. Audicote Acoustical Plaster is a low cost acoustical material designed for either modern efficient machine application or conventional hand application methods over a wide range of surfaces. It can be applied over properly prepared gypsum or Portland cement basecoats, monolithic concrete, prefabricated concrete units. The uniform texture resulting from spray application makes Auoicote particularly suitable for use on large continuous ceiling areas. Through modifications of machine procedures and spray techniques, many pleasing textures are possible. It develops a harder finished surface than many acoustical materials, and can be cleaned or painted without reducing the absorption characteristics. It may be applied over properly prepared gypsum plaster or Portland cement-lime plaster basecoats. It may be machine applied; however, the published sound absorption data does Audicote is readily adaptable to tinting, and incorporation of special aggregates to further increase the design and decorative possibilities. Few other acoustical products present the designer with the flexibility and adaptability of Audicote Acoustical Plaster. FUNCTION ANO UTILITY not apply in this case. . Sound Absorption--Noise Reduction Coefficient of .55. FUNCTION AND UTILITY Sound Absorption--Noise Reduction Coefficient of .60 when stippled or stipple-perforated. When siippled, I Ii-Lite exhibits outstanding sound absorption characteristics at the lower frequencies. High Light Reflectance--Light reflectance of 80% for the normal stippled finish. Maintenance--Hi-Lite Acoustical Plaster may be cleaned with vacuum cleaner using a soft brush attachment. Paintablc--May be redecorated with up to four coats of spray Light Reflectance--When machine textured, has light reflect ance of 65% for Satin White, and 70% for Special While. Maintenance--May be economically refinished with a spray coat of Audicote. Painlnble--May be redecorated with up to two coats of spray applied Texolite* Standard Paint with no loss in Noise Reduction Coefficient. Up to four coats result in only a minor reduction in sound absorption characteristics. Colors--Available in Satin White and Special While. AumroTF. may also be tinted on the job. applied Texoiite Standard Paint without reducing sound LIMITATIONS OF USE absorpuon characteristics. 1. Audicute is designed for use on ceiling and wall areas not LIMITATIONS OF USE subject to contact, excessive vibration or high moisture. 1. Hi-Lite must be machine mixed in strict accordance with directions to develop proper density and working qualities. J 2. Hi-Lite may be machine applied, but published sound absorption coefficients do not apply unless hand applied and finished in accordance with specifications. 2. SrEctnto precautions must be laken under ccriain circumstances to prevent the migration of water-borne.stains to the surface of Audicote. (See Specificaiions on Page 4.) 3. Audicote is not recommended for use over radiant heating installations. o w " -- T. m. R.o- U.s. pt. on. UNITED STATES GYPSUM 7 9B00T 0175 tit'll SPECIFICATIONS V.
