Special finishes solve building owners' problems.As Mark Twain once remarked that "... reports of my death have been grossly exaggerated," so, too, have reports of plastering's death, due to costliness, lack of artisans and un-competitiveness, been equally exaggerated. The difficulty of readily seeing plasterers' contributions to today's construction projects is that the face of plastering plastering, house construction technique involving the application of plaster to walls and ceilings, exterior plasterwork being of a different composition and generally known as stucco. has changed so dramatically. Today, the mental picture of a plasterer in his white work shirt and overalls with plaster residue smeared smear v. smeared, smear·ing, smears v.tr. 1. a. To spread or daub with a sticky, greasy, or dirty substance. b. almost artfully over his studied face planning his next pass, has been replaced by the equally studied faces of tradespersons whose "artistry art·ist·ry n. 1. Artistic ability: a sculptor of great artistry. 2. Artistic quality or craft: the artistry of a poem. " with hoses, spray guns and/or trowels is now being seen applying a whole host of special finishes. In New York City New York City: see New York, city. New York City City (pop., 2000: 8,008,278), southeastern New York, at the mouth of the Hudson River. The largest city in the U.S. , the Plasterers' Union has an active and continuing apprenticeship program turning out contemporary young plasterers. Nevertheless, to meet market demands, nearly 50% of the union's membership devote their skills to the application of special finishes. Spray fireproofing fireproofing, method of making normally combustible materials as nearly noncombustible as possible. Fireproofing generally applies to textiles and construction materials that are treated with a solution or coating of some substance that will tend to retard their , acoustical plaster, sprayed acoustical and thermal insulation The term thermal insulation can refer to materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer. Heat is transferred from one material to another by conduction, convection and/or radiation. , spray texturing and cementitious ce·men·ti·tious adj. Of or relating to a chemical precipitate, especially of carbonates, having the characteristics of cement. [From Latin caement exterior walls are some of the most important special finishes that protect or solve problems in today's modern buildings. An acoustical plaster is one of the easiest special finishes to understand. Sprayed-on acoustical plastering and insulation help architects solve the problem of reducing the high level of noise inherent in many building projects from tunnels and theaters to arenas and boiler rooms boiler room n. a telephone bank operation in which fast-talking telemarketers or campaigners attempt to sell stock, services, goods, or candidates and act as if they are calling from an established company or brokerage. . Reverberation noise problems can be significantly reduced by a layer of acoustical/thermal insulation. If necessary, acoustical/thermal insulation can be applied up to 4" thick. Its standard colors are white, black, gray and tan, but it can also be specially-colored to whatever shade is required, if aesthetics aesthetics (ĕsthĕt`ĭks), the branch of philosophy that is concerned with the nature of art and the criteria of artistic judgment. is an issue. Old plastering that's already in place not working well? Not a problem! Specially-mixed acoustical/thermal insulation compounds are available that can be applied directly over 15-25 year-old existing plastering, and the new application will work just fine. If heat loss is a greater problem than sound, a uniform coat of spray insulation can significantly reduce heat loss with R values up to 20 or better. Another special finish, spray fireproofing, comes in a variety of forms and applications, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. a building's need. Originally developed in 1950, this special coating has become an American standard for fireproofing steel-framed buildings economically, safely and effectively. Spray fireproofing accounts for nearly 70% of all special finishes work today. It has become an American standard, because it can provide whatever degree of fire retardation retardation: see mental retardation. an architect/ engineer requires, without adding any significant weight to the building. In addition, the normal degree of fire retardation, now called for in most building specifications, can be met by spray fireproofing and would add under 1% to the total project cost. Virtually 100% of all commercial and municipal buildings built today that have sprinkler systems are also protected by spray fireproofing to one degree or another. Spray fireproofing (passive fire protection Passive fire protection (PFP) is an integral component of the three components of structural fire protection and fire safety in a building. PFP attempts to contain fires or slow the spread, through use of fire resistant walls, floors, and doors (amongst other examples). ), combined with sprinkler system (active fire protection), offer total fire protection. Where really special fireproofing is required, an intumescent fire retardation coating is the answer. Intumescent fireproofing was developed for locations where there is not a lot of space available for fireproofing; where it might be exposed to the environment, and where an exposed structural look is an architectural requirement. This form of fireproofing is so thin that its thickness, for all of its advantages, can be measured in mils (1/1000 of 1"). Cementitious or stucco-like exterior wall panels (or whole walls!) are an example of special finishes on a large scale. This type of exterior wall treatment, whether sprayed or troweled on, results in a highly textured, very architecturally attractive finish. Used on everything from Manhattan high-risers to parking garages, this type of exterior wall is extremely durable, and weathers extraordinarily well. Buildings completed 25+ years ago with such finishes have withstood the test of time and look as contemporary, fresh and attractive today as the day they were built. The face of today's plasterer has, indeed, changed. He/she may be the artisan building the decorative molding you've always admired ... the skilled worker applying the coat of fireproofing ... the involved tradesperson helping you enjoy a concert through better acoustical treatment ... or even that person working off a scaffold scaffold Temporary platform used to elevate and support workers and materials during work on a structure or machine. It consists of one or more wooden planks and is supported by either a timber or a tubular steel or aluminum frame; bamboo is used in parts of Asia. building an exterior wall. But one thing is for sure--the face of today's plasterer is probably your neighbor's face, because the American plasterer is alive and well, thank you! |
