SABINITE ACOUSTICAL PLASTER An effective acoustical corrective and a perma nent plaster finish are combined in this remarkable material, in which myriads of tiny passages absorb sound and stop echoes. In addition to correcting acoustics in churches, theaters and auditoriums, Sabinlte quiets hospital rooms, offices, etc. It is much more economical than deadening felts or drapes. The improved formula is very easy working. TYPES Sabinlte A--For general use on ceilings or above wainscots. Sabinlte B--For troweling to a smooth hard sur face, readily cleanable on wainscots or wall surfaces exposed to abrasion. - Sabinlte 38--Specially developed to resist mois ture in natatoriums, shower rooms, laundries, etc. COLORS Both Saldnite A, B and No. 38 are furnished in while and four standard colors or tints: ecru, ivory,* cream, buff. Special colors will be furnished on orders exceeding S tons. On small orders where special colors are required Sabinlte may be integrally tinted on the Job. COVERING CAPACITY One ton of Sabinlte A or B applied in two coats, each Vi-ln. thick, will cover from 100 to 1 lOsquare yards. The average plasterer can apply 100 square yards of Sabinlte A to full specifications in 11 hours. To mix this material, including delivery to the mechanic, requires but 7 hours of labor.* ^ A ton of 5blnll Hn. .tB ^---- Iw-.en.u.TB ! i i GF003 1703 ;* >'r f 4* J t T CT003 17PM HOW TO AVOID PLASTER TROUBLE Hun dltacHona apply to all Gypium Cament Pladatf, Wood Fibei Ftiilin, and finlibn.

Rule 4.--Sand Ouallty--Sand meeting Ibe requirements ol A.S.T.M. lor fineness la desirable. The setting time ol U S G cement plasters la practically Independent ol sand quality. Sand should be bee bom boat. Rule 9.--Keep Set-Up Plaster Out of the Mis--Set plaster causes quick-set. Clean tbs mortar bos and tools alter each gauging. Do not wash loots In the gauging water. Do not mis one ganging with another. Do not relemper plaster after H baa commenced to set. Throw It away--It la time and money saved. Rule 6.--Mis Material as Needed--Apply mortar Imme diately after mining and do not mis more material than can be bandied in about one hour. Rule 7.--Mining Methods--The manimum strength and uni formity of sand and plaster mixtures depends on getting a per fect mis on the Job. Uneven distribution ol sand In plaster may result In weak ovarSanded spots duo lo Incorrect mining prac tice. Mining should be continued until sand and plastet are thoroughly incorporated. Machine miners should be kept clean and bee bom sal plastet. Rule B.--Keep Green Walls From Freaslng Until Set Herd--Frost will not Injure platter after setting occurs, and walls may be allowed to heete dry. Whenever there Is Ukelihood ol boat In beaecoat plasters, they should be warmed and dried thoroughly before finishing. DRYOUTS ' "bryouta" occur when plastet coats dry before tbs plaster sets. U S G cement plaster, with ordinary protection bom loo rapid 34 \ drying, it practically prool against this condition, under wide variations In sanding conditions. Where dryout occurs, it la Indicated by soft, wea, chalky areas in the plaaler. It is corrected by spraying the area affected with water to dampen II thoroughly, then keeping the wall damp until platter tell. Dried oul plaaler retains its selling properties, and need never be removed unless buckling of wood lath baa cauaed failure ol keys. Where rapid correction ol dryouts Is resulted, the surface may be welled with a solution, made op by dissolving 6 ounces ol sine sulphate or slum In 12 quarts ol water. Wet Ibe area Involved evenly, with this solution,,then dampen thoroughly with spray or brush. SWEAT-OUTS Cause--A "sweat-out" Is the opposite condition to a dry-out. Walls In this condition ate set out the water in esceas ol the amount needed lo cause crystallization has not been ezpelted, thus causing a partial re-disaolvina of the gypsum. Sweal-ouls are more likely to be encountered In winter than In summer. How to Detect--This condition will be recognised when walls remain damp. Instead ol being white and chatkv, as In the esse of a dry-out, the walls are dark In color and soft, and if the condition Is permitted to continue uncorrected, the walls win have a damp, musty odor. . How to Prevent--It Is important to dry out the walls as quickly as possible alter they are set. Plaster which has set but still temalns damp over an extended period of time loses Its strength and may result |n a total loss. However, when e sweat-out condition Is delected. Immediate provision lor proper heat and ventilation will ptesarve the remaining strength ol the plaster. If, after the walls are set, door* and windows are opened to permit a bee circulation of air, and U In extremely cold weather proper artificial heat be also introduced into the building, together with proper ventilation, there will be no danger of sweat-outs. ' Remedy--After the plaster has set open np doors and win dows. In very cold weather also use artificial heal to dry out the walls. FROZEN PLASTER Cause--Wails hearing before they ate set. How to Detect--U the temperature Inside the building was at a heeting point before the plaster set and if the walls remain damp and dark In color, the plaster Is probably bosea. How te Prevent--In order to prevent bearing before the plaster has sat, use artificial heat In the building with good ventlfation. Frost will not Injure plaster which has set if no excess moisture Is present.. 39 t I rs *-* >r,i/ -w 4 crooj 17BS a Remedy--Keep lli* building closed. Provide artifical beat and completely Ibaw oul walla. When platter baa thawed and eel, provide ventilation and beat to remove molature and prevent a sweet-out. . Never applr * finish coal over a bate coat containing Croat. TOO SLOW SETTING Cause--Tbe (citing time oi U S G cement piaster la ad|usted to meet tbe requirement* ol tbe locality into which it la shipped. If, because ol special conditions this setting time is too slow, it may be adjusted and dealer should be notified so that this adjustment can be made. How to Detect--When plaster fails to set in a reasonable time alter mixing jl'AbB hours, depending on locality) it I* alow Setting. U 8 Q cement plaster* set bom the lath out, tbe surface setting evenly and uniformly, so that surface Is last to harden. Surface softness, therefore, should not be confused with slow setting. Before definitely concluding that a plaster Is slow setting, H is well !o make a simple test as follows: mix dry a sample id sanded plaster on a clean hawk or mortar board. Put about a pint (two tumblerfuls) of tbe mixture in the center of the hawk or mortar board. Now, with the handle of a pointing trowel make a' hole In the center of the dry-mixed material and work it Into a ring about 9 to 8 In. tn diameter. Into this ring, pour clean water, then fold the plaster Into the walet slowly and mis thoroughly. Place the mixture on a well cleaned wet board, or better still, on a piece of glass, or the bottom of an old plate or saucer. Take the time ol set. The time will vary bom an hour and a half In some parts of the South, to four hours or mot* In other section*. . Remedies--Below are listed five thing* which mSy be don* to make plaster set more quickly. None oi these remedies will hash any injurious effect on the plaster. (1) Send to the United State* Gypsum Company for U S G . Accelerator. Add 4 to 6 oi. (about a handful) to each sack ol plaster. (2) Crush some plaster droppings, screeq through a 0* screen. and use about a quart of this set plaster to each . . sack of plaster. (3) Add about a quart ol hydrated Mm* to each sack. (4) Add about a quart of Portland cement to each sack. Caution. The use of lime or Portland cement to accel- arete the set Is not recommended over ftocklath. Insulat ing Lath, or any sheet type ol lath. (5) Put IS lb*, of any kind of unrelarded plaster (plaster ol parts, moulding plaster, etc.) Into a barrel ol water about * on* boar belor* it I* desired to mix the plaster. Use this water, thoroughly (lined, lot mixing. 38 TOO OUICK SET Causae--The setting time ol U 3 G cement plaster Is adjusted to meet the requirements ol the locality into which tl is shipped, and is practically independent of wsler supply and sand quality. Quick set may be due to: (1) U*a ol water la which tools have been washed lor mixing; (2) Ptesence ol set piaster la the mix; (3) Mixing more material than will be used up In an hour. How to Detect--Material which seta in the box or the mixer, or harden* on the wail before it can be straightened, is quick set. II there Is any doubt as to the condition, mix a little as described under--"Too Slow Set--How to Delect" How to Prevent--Most quick-set bouble* can be prevented S' correcting local conditions dsscrtbed nndsr "Cause* ol nick Set" . Remedies--Coned local condition*. Sea that tools and mixing box tra baa bom sal plaster. See that mixing water does not contain sat plaster. Do not permit plaster end sand to stand dry mixed before adding the walar. Do not mix mora material than can be used up in an hour. U an Investigation of local condition* doe* not suggssl a remedy, obtain bom Ihe United Slates Gypsum Company soma U S G Retarder. Use this by attrting op the desired amounl in a pall containing part el the mixing walar, lo gel a good solu- 8on baa from lumps. Start with a fair handful (1 to 2 ounces) per bag Incraastng or decreasing the amount as necessary to obtain dashed Setting time. If there is not time to procure U 5 G Retarder the set may be retarded by Ihe addition ol glue water. Pulverised glue In lb* proportion* ol 1 lb. of glue to 9 gallons of water should he mixed, and about a quart pall full of this solution used with the gauging water lor each 100-lb. tack el plaster. U S G Retarder Is much better than glue.
