Some finishes are used as a base for decoration while others provide the final finished surface themselves. There are several types of gypsum finish plasters, soma re quiring the addition of water only amt aoMta which era a blend of gypsum, lime and water, or at gypenai, lime, sand and water. They are selected according to Job requirements for texture, color, hardness, sound absorption and for compatability with the basecoat. Since the finish plaster coat comprises about 75% of the visible room area, it is Important to select high-quality mate rials, mix them properly and use according to directions. 88 products: finish plasters USG FINISH PLASTERS-TECHNICAL DATA Product ORIENTAL Interior Finish Plaster STRUCT0GAUGE and Lime Putty Finish Texture Float or Texture Finish Smooth Trowel DIAMOND Smooth Finish Trowel IMPERIAL Smooth Finish Trowel OK.

The degree of hardness, porosity, and polish is determined by the materials and application techniques used. When a smoothtrowel gauged lime putty finish is used over a basecoat con taining lightweight aggregate on any plaster base, it is neces sary to add at least 50 lbs. of fine silica sand or Vi cu. ft. of perlite Anes per 100 llw. of gauging plaster to improve the compatibility of the finish with the basecoat. Float or Spray Texture Finishes: provide pleasing, durable finishes where surface textures are desired. They are recom mended for use over all types of gypsum basecoats and are the most desirable finishes from the standpoint of crack-resistance.The surface texture is easily controlled and can be produced by spray application, or a variety of hand tools. Other Texture Finishes: many pleasing and distinctive tex tures are possible using various techniques in finishing. Fin ishes may range from an extremely fine stipple to a rough, heavy or course texture. Variety is limited only by the imagi nation of the designer or the ingenuity of the applicator. ORIENTAL INTERIOR FlNtt8 PLASTER This is a factory-prepared white finish containing property graded aggregate to insure easy-working qualities and uni formity in results. It may be applied to produce many types of surfaces ranging from very fine sandfloat finish to a heavy texture. It is highly resistant to abrasion because of its great hardness and is uniform in color. To eliminate need for further surface decoration, color may be added to the plaster mix. 90 products: exterior stucco Mixing and Application: add clean water only and hoe the plas ter into the water. Allow to soak 20 or 30 min. and mix thoroughly to a smooth, creamy, easy-working consistency. This plaster must be applied to a set, "half-green" basecoat of gypsum plaster. If the basecoat is exceptionally dry, it should be sprayed uniformly with clean water the night before fin ishing. Apply by hand in a two-coat double-back operation. Scratch in a thin coat well ground into the base, and double back with a second coat, filling out to a true, even surface. The surface can be floated with a sponge, sponge rubber or carpet float. Do not use water while floating. The finish can be applied in any desired texture except a smooth trowel finish; also can be spray-applied. For uniform appearance, spray finishes must be applied over a smoothly troweled level plaster surface. DIAMOND FINISH PLASTER A pre-mixed interior finish that provides exceptional surface hardness, greater crack resistance and excellent troweling fea tures. See Chapter 2 for complete description and application. ORIENTAL EXTERIOR FINISH STUCCO Omental Exterior Stucco is a pre-mixed, water-resistant fin ish for use over exterior Portland cement-lime basecoats only. This material is available in 10 designer colon and white for hand or spray application. It is suitable for application on new work or for remodeling and is an economical means of beautify ing in two ways: with texture and color. Machine spray Dashed and troweled Hand float This finish is easy to apply, permanently durable and can be worked in a number of textures: rough coat, stipple, sponge or fine-grained float finish. exterior stucco: products 91 Hand Application: Omental Exterior Finish Stucco needs only the addition of water. Use clean water and measure accurately. Do not add anti-freere, waterproofing compounds or sand. Hoe the stucco into the water and allow to soak approximately 16 min. Then hoe thoroughly to a smooth consistency. Mix each batch for the same length of time to insure color uniformity and mix only enough material for 8 hours' use. 2$4 $ Spraying base for ORIENTAL Exterior Finish Stucco Apply Omental Exterior Finish Stucco only over a Portland cement-lime and sand basecoat that is level but left rough under the darby, or broomed and properly cured. Water-spray basecoat to provide a uniformly damp "half-green" surface. Remove loose and projecting particles from th > basecoat Then apply a thin coat well ground into the base and completely covering it. Double back and fill out to a uniform surface about H* thick, covering total area in one operation to eliminate joinings. Trowel three or four times before starting to texture. For a float finish, use a cork, wood, carpet or sponge rubber float and work the surface to an even texture, free from blemishes, as the material stiffens and starts to set. Floating must be done without the use of additional water. Machine Application: Omental Exterior Finish Stucco may be applied in a single-coat or two-coat operation. Excessive mixing water should not be used as this may result in "lime bloom." One-Coat Application: Spray-apply material to basecoat to 92 products: gauging plasters uniform thickness of approximately Work from wet edges to complete an entire unbroken area in one continuous operation to eliminate joinings. Two-Cost Application: Apply first coat with a trowel as in hand application. After troweling uniformly level, apply tex tured second coat by machine-spraying to a total thickness of approx, tt*. After setting, fog-spray surface with water periodically for several days to cure the finish and help to prevent glased spots and "bloom." Apply as much water as is readily absorbed. The frequency of spraying will depend on the weather. gauging plasters and application Lime, when used alone as a finish plaster, does not set, is subject to shrinkage when drying and lacks a hard finish. Gauging plaster is blended into the lime putty in the proper proportions to provide controlled set, early hardness (see Sur face Hardness table page 89) and strength, and to prevent shrinkage cracks. High-strength Rd Top Keenes Cement and Structo-GAlton Gauging Plaster are to be used only over sanded or wood fiber basecoat plasters. Over lightweight aggregated basecoats use white or regular gauging plaster that is properly aggregated.

Champion (quick-set) and Star (slow-set) are white gauging plasters for finish work. Red Top Gauging is slightly darker in color and is available in quick-set (QS), and slow-set (SS). These plasters are also available with added perlite fines and are designated as "Qual ity," for use over lightweight aggregated basecoat plasters. Mixing: add gauging plaster to lime putty in proportion of 1 part dry gauging plaster by weight to 2 parts dry lime by weight or 1 part dry gauging by volume to 8 parts lime putty by volume. To mix, form a ring of lime putty on the mixing board. The volume of putty used depends on the wall or ceiling area to be covered. A hod of lime putty weighs approximately 100 Ibs^ a 12-qt. bucket of lime putty about 88 lbs. (60 lbs. dry lime equals 100 lbs. lime putty). After forming the putty ring, pour clean water into the center of the ring in correct proportions: 6 qta. of water to 100 lbs. of lime putty; 2 qta. of water to each 12-qt bucket of lime putty. Next sift "slow", "medium" or "quick" set gauging plaster into water; 26 lbs. gauging plaster to one hod of lime putty. Thoroughly wet the gauging plaster and blend the materials thoroughly to pre vent gauging "streaks" and provide uniform density. Sift gauging plaster Into water Mix to Mend thoroughly To protect against finish coat cheek or map-cracking, add H cu. ft perlite fines or 60 lbs. silica sand to every 100 lbs. of gauging used. This addition is necessary when applying smooth troweled finishes over lightweight aggregate basecoats. Mill-aggregated "Quality" gauging plasters are gener ally available and eliminate the need tor on-the-job measuring. Apply the gauged lime putty over a partially dry basecoat Scratch in a thin coat well ground into the basecoat, and double back with a second coat filling imperfections. After the basecoat has absorbed most of the excess water from the finish, trowel to density the surface. As final set takes place, water-trowel the surface to provide a dense, smooth surface. 94 products: gauging plasters STRUCTO-GAUGE GAUGING PLASTER This is high-strength gypsum finishing plaster designed for use with lime putty to produce an easily applied finish of extreme hardness. It is available in "Quick Set" (80 to 40 min.) and "Slow Set" (00 to 75 min.) and complies with ASTM C28 for gypsum gauging plaster and Fed. Spec. SS-P00402a, Type V and has the added property of a compressive strength of at least 6000 lb. psi when tested in accordance with this specification. Finish hardness may be altered by varying the proportions of lime putty and Stkucto-Gauo*. Since the material cannot be retempered, use regular Keenes Cement when retempering is a factor. StoUCTO-Gauur may be used for wall and ceiling finishes as in residential bathrooms, kitchens and where sur faces of extreme hardness and durability are required such as hallways or traffle areas in hospitals or schools. It is not recommended for use where exceesive or continued moisture conditions exist. Application must be over high-strength sanded or wood-flbered gypsum baseboats, O.K. Concrete Basecoat or Imperial Basecoat only. Mixing: for a "hard finish" mix in proportions of 100 lbs. dry hydrated lime (200 lbs. of lime putty) to 100 lbs. StrvctoGauoe. For a "medium hard" finish, mix in proportions of 200 lbs. dry hydrated lime (400 lbs. of lime putty) to 100 lbs. Stsucto-Gauok. For best results, machine mix. Apply like regular finish over a partially dry gypsum basecoat. Scratch in the thin coat, well ground into the base, and im mediately double back with second coat, filling imperfections. Water-trowel to a smooth, hard finish, free of all blemishes. Continue troweling until final set has taken place. Clean tools and equipment after each mix. RED TOP KEENES CEMENT A high-strength white gypsum plaster used with finish lime putty for extremely hard, dense surfaces. It is the only gyp sum plaster that can be retempered. Made in two types: Type I or regular, slow setting (8-6 hours); Type II or quick troweling, setting (1-2 hours). Quick-troweling Keenes must be used with a minimum of 26 lbs. dry hydrated lime per 100 lbs. of Keenes. Both products comply with ASTM C61 and Fed. Spec. SS-P-00410 Type I and II. Keenes Cement-Lime Finish is similar in many respects to a lime gauged finish except that Keenes Cement, instead of gauging plaster, is used in varying proportions depending on the hardness required and is generally used as a float finish. If a smooth trowel hard finish is desirable, use StructoGauge Gauging Plaster. Keenes Cement is for interior use over sanded or wood-fibered gypsum basecoata. Do not apply smooth troweled finish over lightweight aggregate basecoata. finish limes: products 95 MIXING AND APPLICATION Sand Float Finish: a commonly used, hard float finish which may be satisfactorily colored. Mix in proportions of 100 lbs. Keenes Cement to 60 lbs. dry lime and 400 lbs. sand, with or without lime-proof colors. Apply in same manner as indicated for Keenes Cement-Lime Finish but instead of the final trowel ing, use a wood, cork, sponge or felt-covered float to bring the sand particles to the surface to produce a pleasing, durable sand finish. Keenes Cement-Uase Finish: for medium hard finish, mix in proportion of 100 lbs. lime putty (50 lbs. of dry hydrated lime) to 100 lbs. Keenes Cement. For a hard finish, use 60 lbs. lime putty (25 lbs. of dry hydrated lime) to 100 lbs. Keenes Cement. Apply the finish coat over a set basecoat that has been broomed and is partially dry. Spray with water if surface is too dry but do not soak. Scratch in a thin coat and then double back with a second coat to a true surface. Trowel with water to a smooth, glossy finish, free from blemishes. Continue troweling until finish has set. finish limes and application The purpose of finish lime is to provide bulk, plasticity and ease of spread for the finish coat. There are three types of finish lime: (1) double hydrate, (2) norma) hydrate, and (3) quicklime. Each requires different handling for slaking or soaking in order to produce a good finish lime putty.

It mixes easily by hand or machine, is easy to apply and has ex cellent spreading qualities. Ivory Finish Lime is over 92% hydrated and complies with Fed. Spec. SS-Lr00351a Type F and ASTM C206 Type S. Mixing: machine equipment must be clean. Place 6H to 6 gal. clear water per 50 lb. bag of Ivory Finish Lime in mixer. Using a motor-driven, propeller-type mixer, the complete mixing of lime putty takes 2 to 8 min. and results in a highquality, easy-working putty. Machine-mixed putty is plastic and coverage is increased from 10 to 15%. With a paddletype mixer, the mixing time is about 16 min. Hand-Mixing: for immediate use, place 6% to 6 gals, of water per 60 lbs. Ivory Finish Lime in mixing box. Add Ivory Lime to water and hoe sufficiently to eliminate lumps. Screen putty through an 8-mesh screen Indore using. Overnight Soak: place water hoee in bottom of a level soaking box. Run water continuously while sifting Ivory Finish Lime through screen into water. When lime is soaked in this manner, there should be a small amount of excess water over top of lime. If excess water remains on the surface the following morning, absorb excess water by screening in additional Ivory Lime, allow to soak a few minutes, then blend into putty by hoeing. For use, screen through 8-mesh hardware cloth and mix with gauging plaster that meets job requirements. Apply, following directions in section on Gauging Plasters and Application. RED TOP AND GRAND PRIZE FINISH LIMES-- HYDRATED These finish limes are economical, easy working, uniform, white and plastic. Both products comply with ASTM C6, Type N, and Fed. Spec. SS-L-00351a, Type F. finish limes: products 97 Machine Mixing: produces a smoother more plastic putty, easier to use and with better coverage. Use approximately 6 gal. of water to each 60 lb. bag of Red Tof or Grand Prize Finish Lime. Mix lime and water to a soupy consistency and then pour into soaking box. Soak mix for a minimum of 16 hrs. to de velop maximum workability and plasticity. Screen mix through 8-mesh hardware cloth to assure smooth, lump-free putty. Hand Mixing: slowly sift Red Top or Grand Prize Lime into water in soaking box. Allow material to take up water for about 20 to 80 min. and then hoe briskly to mix thoroughly. Let mix soak for minimum of 16 hrs. to develop full workability and plasticity. For use, screen through 8 mesh hardware cloth and mix with desired gauging plaster that meets job requirements. Apply according to directions in Gauging Plaster and Application section. : j RED TOP FINISH QUICKLIME A high-calcium finish lime, Rn> Top Finish Quicklime pro duces lime putty that is very plastic and economical to use because of its greater yield. It requires 16 hrs. of soaking and must be handled carefully to prevent burns or clothing dam age. Meets Fed. Spec. SS-Q-851 Type C and ASTM C6. Mixing: In slaking Red Top Finish Quicklime, use approxi mately 15 gals, clean water per 60 lbs. quicklime and 18 gals, per 60 lbs. of quicklime. Sift quicklime into the water and hoe immediately, working thoroughly and breaking up all hot spots. Continue hoeing until boiling action stops (about 16-20 min.) and then run material into a water-tight aging box. Soaking or aging of slaked quicklime is necessary to insure complete slaking of all particles, to permit putty to cool be fore mixing, to develop its full plasticity and to permit the putty to stiffen for easier hodding to gauging board. Allow finely ground and pulverised quicklime to soak at least 16 hrs. before using. Select proper gauging putty for Job requirements and mix with the Red Top Finish Quicklime putty. Apply, following directions for particular gauging plaster used, as described in section on Gauging Plasters and Appli cation. 98 products: weather/acoustical plasters hot and cold weather precautions-- finish lime In Cold Weather: a few precautions will result in improved quality and easier working. Where weather and water are cold, lime develops better plasticity when soaked overnight. The best conditions are a warm room and water over 60* F. It is important to note that in cold weather the lime puttygauging mixture requires a longer time to set Therefore, gauging content should be increased or quick-set gauging added to offset the slower setting time. Proper heat and ventilation are masts. Windows should be opened slightly so that moisture-bearing air moves out of the building. Fast drying after netting is essential to a hard finish. Many cold weather problems with finish lime are a direct result of improper basecoat conditions. Finish should go over a set, fairly dry basecoat. Since the basecoat will dry slowly in winter, heat and ventilation are needed. The water retentivity of lime putty, plus a cold, "green" base, does not pro vide enough suction to remove excess moisture. Blistering and cracking can occur due to slow set or the lime may work back through set of the gauging. In Hot Weather: precautions include proper soaking of lime putty. When the sun is hot, hydrated lime requires M to 1 gal. more water per 60 lbs. The water should be cool. Soaking of putty in shade prevents undue water evaporation and helps to prevent curdling and loss of spreading properties. Avoid soaking for periods longer than two or three days. For application of lime putty-gauging finish plaster, make sure that basecoat is set and partially dry. If applied over a dried out basecoat, water will be drawn from the finish coat resulting in severe check-cracking. Spray the basecoat before finish coat application and trowel finish coat until final set. acoustical plasters The main function of acoustical plaster is to absorb sound and reduce noise level. A wide selection of pleasing finishes combined with medium to high light reflection is available. Low in initial cost, they provide greater sound absorption per acoustical plasters: products 99 dollar than most other commonly used acoustical materials. Basically mineral, they are incombustible and provide an added measure of fire safety. USD ACOUSTICAL PLASTERS-TECHNICAL DATA Bag Coverage/ NRC Light Size Ton Product Finish < Reflectance (2) (Lbs.)
