This does away with the winter difficulties of sand -- occasional need for thaw ing, etc. It can be troweled smooth for one coat finish if necessary. USE Red Top Wood Fiber Plaster is used as a base coat plaster over all standard types of lath. Useful for new work, also for patching re modeling and repairing. It is called wood fiber because it contains a small amount of wood pulp fiber to give it cohesiveness and improve its working qualities under the trowel. WITH SAND Use neat for scratch coats on gypsum laths, metal lath and wood lath. For second or brown coat on above bases and for all plastering on brick, gypsum or clay tile use either neat or with equal parts by weight of plaster and dry sand. PACKAGE The 100-pound USG paper bag. Also put up in 50-pound and 10-pound paper bags. BRANDS Red Top Wood Fiber Plaster is the leading USG brand. Dark (gypsite) plaster is sold under the brand name Red Top Eldorado Wood Fiber Plaster.

Where used with sand, plaster and sand are hoed into the water to get a rich mix. Tools and mixing box should be kept clean and free from set-up plaster. Do not retemper. BB022 1535 RED TOP CEMENT PLASTER Red Top Cement Plaster is a gypsum plaster. It is job-mixed with sand and used as the plaster base coat for interior work over all of the stand ard types of lath, including wood, metal, gyp sum and insulating laths, and over gypsum tile, clay tile and brick. Most base coat plastering is done with this type of material. TYPES Most cement plaster is "fibered." Also made not fibered and extra fibered. FIBERED ''Fibered" cement plaster is used for most base coat work. It is fibered with a long tough fiber to make the mortar more cohesive, to prevent droppings and to help hold the mortar in place until it sets. NOT FIBERED Like fibered cement plaster except that the fiber is left out. EXTRA FIBERED Contains more fiber than "fibered" plaster. Usually ordered for plas tering over metal lath. BRANDS Red Top*, Ivory*, Granite, Big-4*, Niagara, Peerless* Hardwall, and King's Wind sor*. Dark (Gypsite) plaster is Red Top Eldorado*. PACKAGE The 100-pound US G paper bag.

It shall be graded from fine to coarse and, when dry, shall screen as follows: all through a No. 4 sieve; 0 to 10 per cent retained on a No. 8; 15 to 80 on 30; 70 to 95 on 50; not more than 5 through 100. MEASUREMENT OF SAND Fourteen to sixteen No. 2 shovels (not scoops) of dry sand to the 100-lb. bag is approximately the right sanding for a 2 to 1 mix; or use six 10-qt. pails to one 100-lb. bag. MIXING--MACHINE MIXING Red Top Cement Plaster can be mixed by hand or machine, mixing only enough material for one hour. Either way, it should receive the same amount of sand and the mixing equipment should be kept clean and free from set-upmortar. Gypsum plasters should not be remixed or retempered. * Rag. Trade-mark ADVANTAGES Red Top Cement Plaster sets from the lath to the surface. It sets in a few hours and dries out in a few days. Early hardness and strength promote speed in build ing, early decoration and early occupancy. FIREPROOF Has the fireproof qualities of gypsum. Gypsum will not burn. It will not even transmit high temperatures until it is calcined. It helps protect the building from fire.

THE FIREPROOF LATH * INSULATING ROCKLATH WEATHERWOOD LATH USE For blending with lime putty to prepare it for application as a finish plaster. In gauged lime putty finish, lime contributes plasticity and whiteness, gypsum contributes early hardness and freedom from shrinkage cracks. USG Gauging Plaster is also used for run ornamental work -- for coves and cornices where a quick setting material is wanted. For this purpose it can be used neat or with some lime putty added. It should be a quick setting type of gauging or should be accelerated. QUICK-SET GAUGING Has a compara tively short setting time. Used for run work (running cornices, soffits of beams, etc.) or for special purposes, or for lime putty finish where mechanic expects to retard gauging himself. SLOW-SET GAUGING Used for lime putty finish. Lime although it does not set itself, accelerates the set of the gypsum. Therefore the latter needs to be slow-setting to give the me chanic time for gauging, applying and troweling. WHITE GAUGING Made from white gyp sum rock selected from special deposits. Pre ferred for its white color. Made under special brands -- see below. LOCAL GAUGING Made from the same rock as Red Top Cement Plaster. Called "local" gauging because made from local rock at each USG rock plaster plant. BRANDS Slow set brands are: Red Top Gauging Plaster, Red Top Star* Gauging Plaster (pure white), and Red Top Superfine Finishing Plaster (pure white). Quick set brands are Red Top Gauging Plaster, and these purewhite brands: Red Top Champion*, Red Top King's Diamond*, Red Top N.Y.C. Mills*, Red Top Quick Setting, and Red Top Fast Setting. Brand names are given to these types to give the mechanic a means of identifying the material he prefers. Order by brand. PACKAGE All USG gauging plasters are shipped in 100-lb. paper bags. From some plants gauging is also shipped in barrels of 230 lb. net and 250 lb. gross and in export barrels ol 300 lb. net, and 320 lb. gross. COVERING CAPACITY USG Gaug ing Plaster on an average covers, when used with lime putty finish, approximately 1000 to 1400 square yards per ton.

It is made from gypsum rock, mined at Southard, Oklahoma, specially hand-selected for size and purity, cal cined at very high temperature to drive off vir tually all water of crystallization and ground to extreme fineness. It is pure white, non-staining, non-corrosive, non-acid, and takes an easily cleaned, high, glass-like polish. It lacks the plasticity common to other gypsum plasters, does not change in plasticity or working qualities with age, takes its set slowly and may be retempered. USE Used over gypsum plaster base coats as a finish coat for high grade plaster work to receive fine decorative treatment and where the utmost in hardness and density is required. WITH LIME Depending on the hardness required, Keene's Cement is used either neat (add water only) for extra hard, or with the addi tion of from 25 to 80 lb. of lime putty to 100 lb. of Keene's for hard or medium finishes, respectively. USE FOR BASE COAT Keene's Cement with lime putty and clean sand can be used for both first and second plaster base coats. See special direction sheet pictured here. SPECIAL US ES Besides standard Keene's Cement, Red Top is also made in three special types: Quick Troweling Keene's, used with lime putty for finish, permitting application and finish in one operation (setting time within two hours); Casting Keene's used neat for cast ing ornamental pieces (quick-setting); and Scagliola Keene's for the manufacture of artificialmarble (initial set, 3 to 6 hours--final set, 15 to 20 hours). PACKAGE Shipped in 100-lb. paper bags. MIXING For Extra Hard Finish, use Keene's neat; for Hard Finish, use 100 lb. Keene's and 25 lb. lime putty (one 12 qt. pail): for Medium Finish, use 100 lb. Keene's and 80 lb. lime putty (40 lb. dry lime). See Keene's direction sheet. COVERING CAPACITY For Trowel Finish, one ton covers: Extra Hard (neat)--400 to 500 sq. yds. Hard (with 25 lb. lime putty)--from 425 to 525 sq. yds. Medium (with 80 lb. lime putty)--from 500 to 600 sq. yds. RETEMPERING Keene's Cement may be retempered (remixed with the addition of water) after its set has begun with no effect on ultimate hardness. APPLICATION Apply thinly and evenly in 2 coats over dry base. Reduce suction of base coat by wetting as required. See Keene's Cement direction sheet.

APPLICATION Perforated Rocklath is applied just like Rocklath--see complete details on application of Rocklath on page 12. ADVANTAGES The outstanding advan tage of Perforated Rocklath is its added resist ance to the progress of fire in lath and plaster construction. It has all the advantages of Rock lath--it is economical, non-combustible, has an even greater bond for plaster. Its plus value is persistence of the bond between the lath and plaster for a longer time after having been attacked by fire. ONE-HOUR FIRE RATING Tests con ducted at the U. S. Bureau of Standards on a Perforated Rocklath partition, plastered with onehalf inch of gypsum plaster, demonstrated that this construction had sufficient fire resistance to be qualified for a one-hour fire rating. Hundreds of cities have already granted authority for the use of Perforated Rocklath for one-hour fire construction. MAXIMUM BOND WITH PLASTER Plaster applied over Perforated Rocklath bonds with a double grip. First of all, the surface of the lath forms a stronger bond with plaster than any other type of lath. Secondly, plaster penetrates the holes, and forms stout "mechanical" keys 14- .// BB022 1544 % ROCKLATH, THE FIREPROOF LATH ADVANTAGES Rocklath* is fireproof, rigid, non-warping; it forms a stronger bond with plaster than any other type of lath.

Its insulating efficiency is based on a new inciple, briefly outlined as follows: CONDUCTION Hold a poker in a hot fire d the heat travels from the fire to the hand mg the poker by conduction. CONVECTION Stand over an open register; 5 hot air flows up the pipe. This heat travel by convection. RADIATION Heat travels from a fireplace d warms the hand without warming the air tween. This is radiant heat. Heat passing through the walls or roof of a ime building (from inside out or from outside ) must pass across the air space between the ids and rafters. Approximately seventy-five r cent of such heat travel is by radiation. Insulating--Rbcklath resists the passage of radiant heat. It resists summer heat by reflect ing it back as a mirror reflects light. In winter time, when the heat flow is out ward, Insulating Rocklath insulates by reducing the flow of heat by radiation.

Bright surfaces that are efficient in reflecting light and radiant heat are also efficient in refus ing to emit or give off heat by radiation (Kirchoff's Law of Physics). Insulating Rocklath reflects approximately 90 per cent of the radiant heat coming in contact with it, whereas other materials, such as wood, brick, and fiber reflect only about 10 per cent. The aluminum surface does not dull appre ciably. The slight ultimate oxidation reduces but little its reflecting and non-radiating quality.

It is adapt able to all types of frame construction, to steel stud partitions, and sus pended ceilings. ADVANTAGES Al most entire elimination of cracking, freedom from lath and joist streaking, permanence, fireresistance, better sound insulation. ERECTION The only materials used in the construction of the Rocklath Resilient Plastering System not used in ordinary plastering construc tion jobs are the resilient clips. Various types of clips are used to apply Rocklath resiliently for various types of construction. Materials used in the system are sold as a unit--bundled Rocklath, resilient clips, and RED TOP METAL LATH RESILIENT SYSTEM USE Red Top Metal Lath Resilient System, by the use of spring clips, provides a prac tical method for resili ently attaching and fur ring metal lath in virtu ally all types of work. ADVANTAG ES Maximum protection against cracking, preven tion of lath and joist streaking, sound insulation. It is adaptable to practically all types of resi dential arid commercial fireproof and semifireproo) construction, suspended ceilings, wood frame,/construction, steel-stud partitions and masonry surfaces. MATERIALS For use in the system five different types of clips and a special steel Channel stud and seat are available. All parts of the system are sold as a complete unit. SPECIAL METHODS FOR ATTACHING ROCKLA otu i c NOTE: The Company will furnish on request bulletins giving complete information on the systems described below. USG BRIDIOINT SYSTEM In this system Rocklath is nailed to studs in the standard way with 5 nails per width of board except that end joints of the board fall between, rather than on, supports. To reinforce end joints, a special clip--No. W-22--is used. Advantages of this system of Rocklath attachment are: (1) All Rocklath joints are kept off wood framing--this helps reduce a common source of plaster cracks caused by movement resulting from the expan sion and contraction of wood. (2) Comers are not nailed--instead Rocklath meeting at comers is secured with another type of clip--No.W-33 --permitting free movement of wood framing at comers. (3) Waste is greatly reduced--all lengths of lath can be used. (4) Framing mem bers need not be spaced exactly 16 inches on centers; this reduces framing cost materially. USG "FREFLOTE" CLIP SYSTEM The Freflote System for Rocklath offers six meth ods for the attachment of lath to wood or %-inch steel channel framing. Each method has a dis tinctive semi-rigid or "knee-action'' clip to hold Rocklath to supports. The system tends to reduce plaster cracks by minimizing strain on lath caused by movement of framing. It provides construction using stand ard grounds, or a self-furring plan to eliminate lath stains, with 1%-inch grounds. The system also offers the Bridjoint principle if desired. /$'v: / (h the Resilient. Rooklath Plastering System - presents the greatest possible protection against oracks.

Its function is to help prevent plaster cracks and streaks and to provide an economical method of fireproofing. Metal Lath walls and ceilings resist the strains of settlement, wind, earthquakes, impact, vibra tion, etc. and retain their firm, smooth surface, unmarred by cracks. Walls and ceilings of Metal Lath covered with three-coat plastering have been accorded a one hour lire safety rating by the Underwriters, and therefore should be used in all classes of build ing at as many of the following points as possible: 1-All stud bearing partitions and stud exte rior walls including fire stops. 2-All ceilings, particularly under inhabited floors, over heating plant, fuel storage, etc. 3-At chimney breasts, around flues and back of kitchen ranges. 4-Stairwells and under stairs. For economy in floor space, use 2-inch solid Metal Lath and plaster partitions on non-bearing walls and also for stair and elevator enclosures. MATERIALS USED Red Top*Metal Lath products shown on pages 16 and 17 are made of the following standard lath materials, each distinctly tagged for identification: Open Hearth Steel (Painted Steel)--A com pound of iron and carbon with few impurities (phosphorus, manganese, etc.).

ERECTION After location of partition has been determined, the steel angle "shoes" are nailed to the floor at stud-spaoe intervals. On either side of these "shoes" are placed the pieoes of metal base, whioh are then attached to the "shoes" securely by means of the base dips. a naiJL serves as a key to ettaoh the base dips to the "shoes", as a final step, the steel channel studs are set into the "shoes" and their upper ends engaged in the oeiling angle runner. Before the metal lath is applied, a quick setting grout should be applied to the base for sanitation and sound deadening. / CD COP ro in iun> RID TOP METnL LATH RESILIENT PLASTERING SYSTEM FIREPROOF "FLOaTING" FLaSTER .,'aLL aNT> CEILING CONSTRUCTION aDVaNTaGSC a method of ocnstractiftg plaster walls and oeilings so that: (1) there is maximum prptsotion to the plastered surfaces against cracks oaused by movement in the framing; (2) the trans mission of sound through the walls and ceilings is reduced; (3) there is maximum protection against the appearance of joist streaks. The System consists of attaching metal lath to the supporting frame with speoial resilient clips, instead of nailing the lath securely to studs and joists.

It requires only soaking to proiuce lime putty ready to use, free from the posibility of "pops" and "pits." It is used with ied Top Gauging Plaster for the lime putty mish coat which is applied over any of the -ypsum base coat plasters. It is occasionally ised, mixed with sand, for plaster base coats nd as an ingredient in stucco base and finish oats where it adds plasticity and waterproofing. TYPES There are two types of U S G Hydrated mishing Lime, ''Dolomitic'' from the North western Ohio dolomitic field and "High Callum" manufactured at Farnams, Mass., and 'iew Braunfels, Texas. Dolomitic limes are produced from limestones :ontairiing, in addition to calcium, a high per:entage of magnesium. High Calcium limes are jroduced from limestone composed largely of ralcium and a small amount of magnesium. BRANDS Dolomitic Finishing Lime from Denoa, Ohio, is shipped as Ivory, Grand Prize*, md Red Top Hydrated Finishing Lime. High Dalcium Finishing Lime from Farnams is sold -r.aer the Cheshire brand, and from New Eraunfels, Texas, as Plastimax*. PACKAGE The standard package is a 50-lb. multiwal] paper valve bag. Plastimax, however, i* shippe d only in a 40-lb. paper bag. MIXING AND SOAKING Pour water mto clean, tight, wood or metal box. Sift dry hydrated finishing lime through a coarse screen into the soaking water, until the water is com pletely absorbed and the surface shows a lightly cracked appearance. Use about 6V2 gallons of water to the 50-lb. bag. Allow to soak undist-tbed, for at least twelve hours. Protect from 'rest, evaporation, and dirt while soaking. Hoe P-ttv through Vfj-inch mesh screen to bring smooth, even, texture. Soaking develops r.astioitv. Many plasterers produce a smoother, re pidftio putty by hoeing the lime thoroughly 1..- tr.er. running it through an 8-mesh screen ar. agir.g box and allowing to remain for ! -ea?: ._ hours, or overnight. P*ast....ax has the advantage of requiring no " -at.r.g It can be mixed with water, hoed thor . and used immediately. CADGING Lime putty finish is made of ar'^ calcined gypsum. One part dry Plaster is added to 3 parts of ' F- -' c>' volume (equal to one part dry **-*...* Piaster to 2 parts dry hydrated lime by weight). Make a shallow ring of lime putty on the gauging board, add water, sift gauging plaster into water, allow to soak and become thoroughly wetted, then mix with the putty. COVERING CAPACITY Depending upon the mechanic, conditions of application and trueness of base coat, one ton of U S G Hydrated Finishing Lime will cover from 500 to 700 square yards. ADVANTAGES USG Hydrated Finishing Limes offer uniform, snowy whiteness and free dom from black specks and unslaked particles which tend to cause popping or pitting in the finished work. Thoroughly hydrated at the fac tory, they are not subject to deterioration in storage when properly stored in a dry warehouse. Complete tests are constantly made at every stage of manufacture, to assure a uniform prod uct of maximum plasticity and covering capa city. Not only is the quicklime thoroughly hydrated, but the resulting product is air floated to eliminate all impurities. BB022 1556 USG FINISHING QUICKLIMES USE USG Finishing Quicklime is used with Red Top Gauging Plaster for white or lime putty finish coat applied over any of the gypsum base coat plasters. It is also used, mixed with sand, for base coat plaster and as an ingredient for stucco base and finish coats where it adds plas ticity and waterproofing. Quicklime requires time for slaking and aging before use. TYPES USG Finishing Quicklime is made from High Calcium rock at Farnams,;Wass., and Ney Braunfels, Texas. At the Farnams plant, it is made in lump, pulverized, fine grained, and superfine; at New Braunfels plant, in lump and pulverized. The difference between lump, pulverized, fine grained, and superfine is the fineness of the grind. The finer the grind the quicker and more thorough is the slaking process. BRANDS Farnams lime is sold under the Cheshire brand. New Braunfels under the Peerless brand. PACKAGES Cheshire lime is shipped in 80lb. moisture-proof paper bags, Peerless in 50and 100-lb. waterproof liner paperbags. Cheshire is also shipped in 180- and 280-lb. net wood barrels or steel drums; Peerless in 180-lb. steel drums. All types of Cheshire lime are sold in bulk. Peerless is sold in bulk in lump only. SLAKING Fill the slaking box half way with water, allowing the hose to run while the lime is added. As the lime is added, agitate it vigorously with a hoe. These limes slake quickly and must be submerged at all times to prevent burning. When mixed to a consistency of heavy cream, screen through an 8-mesh screen. AGING After screening, run mixture into an aging box. Lime must be aged until it is cool and the putty is hodable. Lime putty produced from quicklime should never be used until aged at least one week and a longer time is preferable to assure complete slaking of all particles. GAUGING See preceding page. COVERING CAPACITY One ton of quicklime when prepared and mixed as above should finish 1,000 square yards. ADVANTAGES The advantage of quick lime over hydrated lime is its greater putty yield, ton for ton. Quicklime putty must, how ever, be thoroughly aged before use. In the early days before the introduction of gypsum plasters when quicklime was universally used for plastering, both for base coat work and finish, the plastering contractor often slaked and pitted lime putty to age for a year before use--thus, much old time plastering has stood the test of time over generations. USG Finishing Quicklimes are made from selected high calcium rock in completely mod ern USG mills. Burning kilns are of both the shaft and rotary types. The same high standards of quality inherent in all USG building materials are present in USG Finishing Quicklimes. Unified labor atory control assures com plete uniformity of product. 122 5G MASONS HYDRATED LIMES For masonry mortar of good plasticity having good waterproofing qualities. iu of Standards' Research Paper R. P. "A Study of the Properties of Mortar Brick and Relation to Bond," establishes veakest point in brick work to be at the ure of the masonry unit and the mortar, and numerous field observations made by Detent authorities indicate that brick masonry ; can be made water-tight by the proper use on-shrinking mortars which form a solid 1 with the masonry unit. Lime and Portland ent mortar for masonry above grade fulfills ectly this specification when mixed as here!er specified in the proportions of 2 parts of putty, 1 part of cement, and 9 parts of sand ^portions by volume). Standard Portland :ent mortar gauged with at least 10 per cent ime has increased plasticity and workability veil as waterproofing qualities.

In bulk MIXING Thoroughly mix the hydrated lime (dry) with sand or with sand and cement, then add sufficient water to bring mix to hodable consistency. The following proportions by volume are recommended: $6 MASONS LIME EXCELLENT FOR USE IN CONCRETE 1 - For common and face clay, shale or sandlime brick in dwellings and similar construction --1 part of lime to 3 parts of sand. 2 - Clay or shale brick in walls and piers below grade continuously exposed to wet or damp condition -- 1 part of lime, 1 part of Portland cement, and 6 parts of sand. 3 - Common and face clay, shale or sandlime brick in exterior walls and piers above grade--2 parts of lime, 1 part of Portland cement, and 9 parts of sand (2.25 cu. ft. of putty per 100 lb. of hydrate; 94 lb. per cu. ft. Portland cement; 80-85 lb. per cu. ft. sand, loose and moist). ADVANTAGES Hydrated Limes are scien tifically slaked by the manufacturer and come to the job ready for mixing and use after soak ing. The advantages of lime mortar for use in brick, tile, or stone masonry are economy, strength, plasticity, and waterproofness. Lime and cement mortar forms a non-shrinking, per manent water and weathertight bond with masonry units and is today advocated by the best authorities for masonry mortars. 23. >. * Reg.

SLAKING Add water and lime gradually while mixing, constantly agitating mixture to prevent burning of unslaked portion. Mix to a thin consistency and screen through a quarterinch mesh screen. AGING After screening, run mixture into aging box. Lime must be aged until it is cool and the putty is hodable. Lime putty produced from quicklime should never be used until aged at least one week. A longer time is preferable to assure complete slaking. MIXING See preceeding page. ADVANTAGES While quicklimes must be thoroughly slaked and aged before use, when compared to the preslaked hydrated limes, they have the advantage of a greater putty yield, ton for ton. They have the same ad vantages as hydrated limes for brick and masonry work and for use with Portland cement. j - B8022 1559 PY R 0 BAR PARTITION TILE USE Pyrobar Partition Tile are pre-cast gyp sum tile for use as non-bearing partitions and for furring. They consist of 97% gypsum and 3% special wood fiber, moulded in steel moulds by a process that insures accurate proportions, and uniform size, weight, strength and density. ADVANTAGES The large, uniform units are much easier and therefore cheaper to erect than other masonry partition units. Straight edges and true faces insure a perfectly even, true wall that takes a minimum of plaster. Exper ience shows that plastering on Pyrobar Tile saves as much as 20% of plaster as compared to other masonry surfaces. Pyrobar* is economical to use. Breakage is almost negligible. Cutting around openings and pipes does not cause waste assail the pieces can be used. Ordinarily from 5 to 7% less Pyrobar Tile is required for a job than clay tile. Alterations in the partitions are easily made after completion of the building. Additional openings in Pyrobar walls may be cut with a saw, saving replastering, patching, and time. FIREPROOF Because made of gypsum, Pyro bar tile are fireproof. Gypsum tile alone have pass ed the Underwriters' requirements for fireproof partitions. Gypsum complies better with the essential of the ideal fireproofing than any other commonly used material. These essentials are: 1 - Incombustibility. 2-Protection of framing against high temper ature. 3-Refusal to expand sufficiently to spall off and expose the steel. 4-Maintenance of these qualities for the dur ation of the fire. SET FAST CEMENT A specially pre pared gypsum cement used with water and sand as a mortar for setting gypsum partition tile and gypsum fireproofing and column covering. Also used as a mortar for interior clay tile partitions. Shipped in 100-pound paper bags.
