This fifth revision of the Monokote Equipment and High Production Procedures Manual mcorporates some new ideas for keeping production up and costs down: larger surge hose, larger ball valve, nozzle shut offs, and a smaller, more versatile nozzle assembly to mention a few Before starting your next job. review this man ual comparing its recommendations to your present job set-up and upgrade wherever possi ble. Again, no single component makes all the difference, but every component makes a little difference. It all adds up to a more profitable Monokote job. Our joint efforts will help keep sprayed plaster fireproofing a viable and profitable product for the plastering industry. j i j : ! ' j MONOKOTE JOB EQUIPMENT AND HIGH PRODUCTION PROCEDURES I. SITE AND PROJECT PUiNNING Pre-setup Planning 1. Review the specifications and drawings and be sure the general contractor and inspectors have the same interpretation as you do. 2. Arrange with the general contractors repre sentative to meet and walk the site to establish the location of your permanent pumping station. a. Select a primary and an alternative setup location. Where possible, pump up the outside or through the core of the building from a single site. During the winter, the core will pro vide some heat and help prevent line freeze-up. b. Be sure of adequate space for unload ing and handling of material for the duration of the job. Space and access routes often change as the project progresses. c. Find a water source with adequate vol ume and pressure. Also check on washout pro cedure and local water regulations. For exam ple. a settling tank may be required. Be certain the general contractor has arranged the neces sary facilities. 3. Determine if any protection for interior sur faces is required. 4. Check to see if tarps are necessary for over spray protection outside the building. 5. With the general contractor, carefully plan the means for maintaining proper temperature and ventilation for your phase of the work m ail weather conditions. 6. Be certain steel and concrete are reasonably dean for proper Monokote application. Remove loose rust or mill scale with a burlap rag or heavy brush. Oil on steel or concrete shouia oe removed with trisodium phosphate or otner cleaners. On concrete, check closely for form oils and curing compounds. 7. Arrange your application schedule with the job superintendent. a. Insist that you be on the floor as soon as the concrete is poured but before plumbing ana sheet metal work have begun. Working around obstacles such as stacked wan board, pipes and hanging ducts can cut your application rate in half and drastically increase labor costs and material waste. b. When fireproofing steel roof decK me roof system (insulation and membrane) must oe complete and watertight. All roof traffic must oe prohibited during and after Monokote applica tion until the fireproofing has dried and full bona strength is attained. Items 7a & 7b should be included m your dig and production commitment. Tell the superinten dent that clear work areas mean you will be ouT of his way a lot faster. II. MIXER, DELIVERY & APPLICATION EQUIPMENT Select a pump with a production capacity well above the desired daily average. Large 30 HP pumps have performed at heights in excess of 50 floors. The delivery system greatly affects pumping rate. Study the conveying eauipment and sys tem information in section IIC .nd in Figure 3 at the back of this manual. Establish a routine preventive maintenance pro gram on all equipment. Note: 1. Pressure release valves should be kept clean and in good working order. 2. Any equipment abnormality -- such as a new noise, uneven surge, etc. -- should be checked immediately. Waiting until something malfunctions could result in a system oiuggec with set material. 3. Install time clocks to measure machine fun ning time. These provide an accurate gauge which to base routine maintenance. The single most important development in m.application of Monokote has been the introduc tion of high production conversion kits Thes^ kits are available from Thomsen Equipment ana from Essick Manufacturing Co. The prmciou' benefit is the reduction of dead space at the enn of the piston stroke. These kits (A) dramatical!', increase pumping rates. (B) make pumps 'ess sensitive to overmixing, and (C) enable suffer mixes to be pumped at higher rates. The latter enables thicker scratch coats, resulting in fewer passes. 64503056 Labor savings through increased pump effi ciency will pay for the kits in a snort time Spe cific pumps and their corresponding conversion Kits are discussed below: A. Pumps 1. Essick TM-30 A very high volume pump which should be fitted with a high production conversion kit. 8-inch diameter high-production pulley, and urethane balls The Essick TM-30 conversion kit isee Figure 2i consists of piston extenders and neavy pattern front covers which protrude into the cavity between the ball check valves. The new front covers have been adjusted to use the standard inlet ball stop pin while reducing inlet ball travel After installing the conversion kit. remove the pump manifold and rotate the pump by hand through one complete cycle to be sure that there are no installation errors. There must be clear ance between the end of the piston extender and the tip of the inlet ball stop pin at the end of the piston stroke. Caution: Due to increased efficiency, it will be necessary to slow the pump to avoid overloading the nozzle. Do not over stiffen the mix. as excessive pres sures and low yield will result. The 8-inch pulley replaces the standard 10-mch pulley installed on the transmission output shaft. With the engine turning at a maximum (2.600 rpm), the 8-inch pulley turns the pump at ap proximately 130 rpm -- a 40 0 increase over the standard 10-inch pulley. Steel balls and seats have been successfully substituted for the standard urethane balls and corresponding seats. This improvement has eliminated the costly replacement of urethane balls. Electric motors and diesel engines have also been successfully substituted for the. standard 30 HP gas engines. Production rates in excess of 1 bag minute (420 bags/7 hours) are possible. 2. Thomsen A-3.75 The A-3.75 is another high volume pump which should be fitted with steel balls and a high pro duction kit. Seat type must be that specified for use with steel balls (see Thomsen Bulletin *23). The steel ball and seat assembly require much less maintenance and pump Monokote more efficiently than the corresponding plastic ball seat combination. The Thomsen A-3 75 con version kit (see Figure 2) consists of a plug for the manifold, the "Thomsen Marvel and a sleeve for the upper ball travel that spreads the shock of the balls impact over the entire length of the pin, reducing pin breakage The "Marvel" is installed by (1) removing the pump housing, (2) removing and discarding the lower ball stop (socket head cap screw and sleeve), (3) placing the plug in the housing with the flat surface down. (4) threading the bolt pro vided through the hoie in the nousing wnere -.'~e ball stop pm was removea. i5i tigntenmg -~e bolt, and 16) remounting the pump m = m;o z With these modifications, the pump output one" exceeds the advertised 33`c increase arc car approacn 420 bags 7 nours B. Mixers 1.

Essick Models i2Q ana 150. and Muller Models 10 and 12CF all are excellent for mixing Monokote and meet me above criteria Rotation speeds between 30-40 RPM are most efficient m reaching proper den sity and mix consistency. Use rubber ,viper blades where available 2. Dust Control tor Plaster Mixers In order to control nuisance dust in plas;er mix ing areas, plaster mixers should be fittec with dust covers. Dust Covers (Patent No 4.2ii 4911 such as the one illustrated in Figure i nave lowered dus: eveis in general mixing areas allowing men and equipment to perform m a cleaner, healthier environment An aoced advantage is reduced engine maintenance resulting from cleaner air, gas and oil filters For more information on job site operations with a dust cover, contact your local Zonoiite Sa'es Office listed on the oack cover C. Water Measuring Devices The basic requirements of a metering svs'e'" are speed of delivery and the ability to repeated1. deliver a pre-set amount ct water A wasn-dc.*.-' hose should always oe used m conjunction .vm a water meter Tms permits cleaning of 're mixer and fine agistments m batch-to-catcn mix consistency. 1. Essick Model AT-60 and Mr. Parts Watermaster These systems utilize a timed e'eeme i.m'c pump to deliver approximately ore ga ; water per second m pre-set quantities up m 57 gallons Both use a 55 gallon drum as a :eservoir storing water for the next Patch wm-e - * mg and dumping proceed This type of system s especially advantageous with ;ow water pres sures and flow rates Timed sump pump sys tems are the best water delivery methods available. 2. Neptune Water Meters For accurate water measuring and high speed operation a high pressure water source should Ready Load & Mix 0450305? Fig. 1 Dust Control for Plaster Mixers be used. A large diameter water supply hose connected directly to the meter will increase water delivery rate. One version of this meter can be pre-set to shut off automatically when a predetermined number of gallons has been de livered. Where low pressure is a problem install a small centrifugal pump in the line to the meter This boosts water pressure and flow rate 3. Quick Fill Tanks Quick fill tanks must hold at least 36 gallons of water and should be equipped with inlet shutoffs for accurate water measurements. Inlet water must be shut off while the tank is dumping. Recovery rate of this system is often slow and depends upon inlet water pressure and hose diameter. Precise water measurement is difficult. 4. The "5-Gallon Bucket" Method This method is not recommended. Usually the mixer man tires early in the day resulting in a reduced production rate and inconsistent mix uniformity. The area around the mixer often becomes a mud hole due to spilled or overflowed water resulting in damage to surrounding material Again, this method is specifically NOT recommended. D. Conveying Equipment High production with minimal buildup o` : material can only oe assured m a ce-vsmooth-walled. full flow system Drag snouc minimized by the elimination of all unnecessar. restrictions and bends.

Safety/Pressure Release Valve The Pali and seat should be checked ana cleaned regularly. The release pressure should be adjusted according to pump manufacturers recommendations, and should be consistent with rated working pressures of other equipment in the system. 2. Bell Reducers (2" x 3") (I12 x 2 ) (I12 X IV4") Bell reducers must be of the conica; tapered type with external male threads This a;:ows the use of female sleeves and/or female swivel fittings. Galvanized reducers are widely usee without problems. Black iron plumbing fit tings are unacceptable because severe mate rial buildup often occurs, restricting material flow and causing premature material set 3. Surge Hose The surge hose should be 3 inch minimum 1.000 PSI working pressure, wire-braided hose Connect hose directly to the reducer on the pump with ground boss spud and fitting, held with a bolt-on clamp. Surge hose should be as short as possible (approximately 25 feet) 4. Ball Valve A 3 inch (approximately 23j inches full flow) stainless ball valve should be used to permit unrestricted flow of material from the surge nose into the aluminum pipe. 5. Elbow Elbows should be long radius. 3 inch inside diameter, rigid aluminum pipe, with no angle less than 90 degrees. The inside diameter of the elbow should be the same as the standpipe 6. Standpipe a. 3 inch rigid aluminum pipe is the only pipe recommended for Monokote application. b. Tight, leak-free pipe unions may be ob tained by using full-taper threaded, galvanized steel pipe couplings; ground unions or victauiic couplings to join the 10 foot lengtns c: c ce Do not use standard, straight-thread conduit couplings often sold with electrical conduit.

Whip Hose Tne whip nose may be f: inches or 12 inches m diameter, lightweight, braiaed hose fitted witn full flow fittings A combination of 25 feet of V : men diameter hose with 17 feet off - men diam eter hose is strongly recommenaed The whip should be well anchored to the edge of the scaf`oid. Length of iv4 inch whip should not exceed 20 feet. The total whip (if 1v2 inch and ivi inch hose are used) should not exceed 50 ft. 9. Gun a When using a scaffold, the gun length should be as short as possible. Closeness to the work keeps waste to a minimum b. The gun may be swivel mounted directly to a 15 foot x 1! 4 inch lightweight whip nose Tne nozzle can then be hand-held, and moved wrtn a paintbrush-like action. This method permits very accurate placement of the fireproofing and -s excellent in cramped spaces where the stan dard gun is toe cumbersome c Pole guns should be used with caution Three ma|or areas of concern are oversprav thickness control and proper application to me tops of the bottom flanges of beams A special gun with a crook' in the shaft which aims the nozzle down on the top of the bottom flange r-as been used with some success.

The machine on off switch should be located at the nozzle and must be in perfect working order. 10. Nozzle and Spray Adjustments a The "azz e snouid have a mcessed seat m which the enkee >5 centered A ` men or nee s recommended `or most applications T"e higher the production rate the -anger me required orifice b An air control valve and movable air stem are absolutely essential. The air s'e must be thoroughly cleaned ana greasea zan, to prevent freeze-up 04503059 ' c The air stem ana orifice must be per fectly centered m the nozzle. The air stem is heic m place witn_ a thumo screw It must oe easily ad|us:ac.e during full operation of the sys tem The stem should be as far back as possi ble consistent with a good fanning action. Proper compmation of air pressure and stem position will create a low-frequency buzzing sound. A high-frequency pitch indicates im proper adjustment d. Air pressure at the nozzle breaks up the stream of fireproofing material so that it can oe accurately placed Do not use air to "blast" the material to the steel. This practice greatly reduces yield. For maximum yield, air pressure should be as ow as possible, consistent with an adequate spray pattern. e. The rubber cap on the gun head is-designed to blow off if there is a nozzle blockage. This is a safety feature and should not be cir cumvented by tightly wiring the cap to the gun. The rubber cap may be connected to the head of the gun with very loose wire: this prevents loss of the cap if blow-off occurs. E. Scaffold A rolling scaffold must be built to provide sta bility and safety to the nozzle man. It should be easy to clean and move. Any strong, lightweight scaffolding may be used, provided the following are incorporated: 1. Wheels should be 8-12 inch diameter for smooth, easy movement so that spraying can continue without interruption. 2. Floor should be of the open grate type: ex panded aluminum lath ie ideal. This permits material to fall through the walking surface and prevents buildup of a slippery layer underfoot. Plywood or wood planks are poor surfaces and inhibit smooth job operation. 3. 3 inch sice guards snouic oe ciacea arou"d the edge of the scaffold floor :o prevent me scadfold hose from slipping off the edge 4. Guard rails should be placed waist h'Ch anc firmly anchored These act as a positive step sc the nozzle man doesn t have to watc.n the edge while spraying 5. Adding a 3 foot cantilevered section to create a 10 foot x 10 foot scaffold makes it possible to span over debris on the floor. This addition mav also be used in sDraying some outside scancre. beams. 6. Putlogs, as long as 22 feet. greatly extend the cantilevered scaffold lengtn. permitting easy access to exterior spandrel beams and exterior columns. F. Tarps Tarping material must conform to local codes and job conditions. For summer use. tares constructed of coarse fiberglass screen me available. These permit good ventilation art: promote early drying and strength developme-In some areas, a denser materia! ma. :? required, such as plastic or heavy cloth G.

PUMP STATION SETUP The entire working and storage area should be covered and protected from weather wherever possible. A. Pump Placement Place the pump as close as possible to the 3 inch diameter standpipe. This permits a short surge hose to be utilized. It is very important that the ground be high enough to permit wash water to drain away from the pump base B. Mixer Place the mixer above the pump hopper. It should be high enough to permit full rotation to the complete dump position. C. Working Platform Build a platform directly Deninc the mixer sc " the mixer mans waist is level with tne foe of the mixer. It snouid oe .arge encugn to " least 20 bags of Monokote Extending the : form around one side of the mixer permits " man to more easily dump the mix and keen- " hopper clean. D. Storage 1 The storage area should be large enoug" hold 600-1000 bags of Monokote or a `j?. approximately 45 feet long. 2. The storage area must be dry and com pletely protected from rain and or construction water. Material must be stored to prevent anv contact with water on the floor 3. Pallets make excellent storage bases When storing Monokote on unprotected ground a layer of plastic should be placed under pallets, and also over the stacked bags. This Drevents ground moisture from damaging the lowest level of bags. The storage area should be imme diately adjacent to the working platform 0450$OO 4. Keep an inventory or at 'east o^e oavs s-ppiy of Monokote to cover any unexoecteo cel ery delay E. Multiple Pump Setups On large jobs, a roller conveyor -.9103 to -eec material out of a van ana aown a .me of m..xers Tnree pumps can use as mucn as ' 000 cags oer day. Witn good equipment and organization one mixer man can handle two mixer p^mc setuDS IV. MIXING PROCEDURE A uniform mix of 50 = 2 pounds per cubic foot (pcf) density is essential to maintain a nign pro duction mixing/pumping operation. To obtain the proper density, follow this procedure. 1. Set mixer speed between 30-40 rpm 2. With blades turning, add water (approx imately 31.5 to 36 U S. gals.). 3. Turn mixer off and clean mixer blades 4. Add two bags of Monokote. 5. Restart mixer, add a third bag and mix for approximately 45 seconds. The mix will initially look dry and will gradually "cream out The mix is usually correct if it is stopped just as the grainy" look begins to disappear. 6. Stop mixer and check the material for a den sity of 50 = 2 pcf (16.0-17.5 net lbs. in a 10 qt pail). If not within this tolerance, restart mixer and adjust density by varying the mixing time and'or speed of the blades (a longer mixing time or increased mixing speed will lower the density level). Once a mixing procedure is determined subsequent mixes will give similar results and this step need not be repeated. 7. Restart mixer 13-5 seconasi then pump entire batch into the pump hopper The mixer must empty completely when dumped to avcic leaving any old mix to be re-worked m the suc ceeding batch Notes 1. Occasionally scrape the inside walls of me pump hopper 2. Wait until enough material has been pumoea out of the hopper to allow sufficient room for me addition of an entre new batch from the mixer 3. If the pump h roper will not take an entire batch, stop the m ^er until the remaining mate rial will fit Restar' me mixer for 2 to 3 seconcs and dump the remaining material. 4. Do not let the pump suck air 5. For maximum yield and minimal oacK pres sure. use as much water as possible consistem with proper hangacm.

After the last mix has cleared the hopper re pump should De slowed and heavily retardec water pumped through the system A sponge . i. * can also oe pumpea through the system If a sponge is to be used, the whip hose and hose reducers must first De flushed and discon nected. A large sponge could plug the system when reaching this area. 2. Dirty water can be pumped into a dram oipe or collected in a 55 gallon drum on the floor 3. If a dram is used, several minutes of clean water should clear the nozzle oefore the pump is shut off. Then close the ball valve and discon nect the surge hose from the pump Secureiy ancnor it to a suitable dram. Reopen the valve and back flush the system as quickiy as possi ble Caution: The surge hose must be se curely anchored to prevent violent whipping action during back flushing. 4. If no drain pipe is available, dirty water >s collected on the spray floor in a 55 gallon drum. When clear water reaches the nozzle it should be collected in a second drum. When the sec ond drum is nearly full, shut off the pump and remove the nozzle. Place the end of the scaffold nose m the first arum of dirty water Close tee oall vaive. connect the surge nose to a s.. tac e drain, and reopen the ball vaive Tee cot. .vatewill be sucKed oacK down through me s,vs:e~' emotying the first drum As tne water apDroacnes tne octtom of the drum cvC' v transfer the hose to the drum of clean water This water ;s sucxec down ourgmg tne e-tne system cf oid material and dirty water 5.

Back flushing can be aiaed by connecting a" air source to the whip hose and forcing m? water back through the system The increased speed of back flushing aids m dislodging an;, remaining material. When back flushing, se curely anchor the surge hose. Air is compressi ble. and will cause a strong whipping actio" v the hose opening. Work crews should k----o clear of the surge hose during back flushing O fi) VI. JOB RECORDS AND MEETING PRODUCTION QUOTAS Experience is one of the best teachers and the best way to improve on experience is to record it. A close count by the mixer man and foreman -- noting each days production and floor change -- is invaluable in checking and improv ing production rates and quantity usage. Keep a permanent log: it will tell you each day if you re winning or losing. Determine the actual pumping rate by timing several consecutive batches at the mixer Em mate downtime and set realistic average ;:a . production quotas Pumping rates of 30G bar: per day with averages of less than 200 are indicators that sfonq. constructive, on-site " :agement is necessary W'th close con" v coordination anc effective crew manaoe " most Monoxote ;OOS should average m . of 200 bags per da;. A "*Xi4Pi 045030S2 FIG. 2 HIGH PRODUCTION CONVERSION KITS j FIG. 3 SCHEMATIC WORK DIAGRAM 4<r Pressure , vni'-^ 'TS .iL .ii.n <_cncnie ALABAMA ARIZONA1 ARKANSAS CALIFORNIA COLORADO fLOPiDA _"ces lCSanGEwES Santa ana AN PRANCISCO OAKLANO i/iMOMs SPB'NGS 3EC-g;a Illinois KENTUCKY LOUISIANA MARYLAND MASSACHUSETTS MICHIGAN MINNESOTA MISSOURI NEBRASKA NEW JERSEY NEW YORK NORTH CAROLINA OHIO Oklahoma OREGON PENNSYLVANIA TENNESSEE TEXAS .
