Significance and Use4.1 This guide provides information and guidelines forconsideration by the designer or applicator of a joint seal. Itexplains the properties and functions of various materials, suchas sealant, sealant backing,

28、 and primer, among others; and,procedures such as, substrate cleaning and priming, andinstallation of the components of a sealed joint. It presentsguidelines for the use and application of the various materials,design of a sealant joint for a specific application, andenvironmental conditions and eff

29、ects that are known to detri-mentally affect a sealant joint. The information and guidelinesare also useful for those that supply accessories to the sealantindustry and for those that install sealants and accessorymaterials associated with sealant use.4.2 In addition to the design and installation d

30、ata in thisguide, consult the sealant manufacturer about applications forits products and their proper use and installation. Consideringthe range of properties of commercially available sealants, thevariety of joint designs possible, and the many conditions ofuse, the information contained herein is

31、 general in nature.4.3 It should be realized that a sealant and sealant joint areexpected to have a design life during which they remainfunctional. However, a sealant and sealant joint will also havea service life. The intent is for service life to meet or exceeddesign life. There are many factors t

32、hat can affect service lifeincluding type of sealant polymer, sealant formulation, com-patibility with adjacent materials, installation techniques ordeficiencies, sealant joint design (or lack thereof), propermaintenance (or lack thereof), and environmental exposure,among others. The designer of a j

33、oint seal should take theabove into consideration when designing and specifying seal-ants for certain applications.4.4 The design life of a sealant or sealant joint should beconsidered in conjunction with the design life of the structurefor which it is used. For example, a building owner may require

34、a new courthouse building to have an expected design life of 50years. Therefore, elements of the buildings exterior envelopeshould, with proper maintenance, be expected to perform forthat time period. As a result of the information in 4.3 it shouldbe realized that a sealant or sealant joint may not

35、perform forthat time period without proper maintenance. Proper mainte-nance could include replacement of localized sealant andsealant joint failures and conceivably complete sealant replace-ment, perhaps more than once, during that 50 year time perioddepending on a sealants polymer base and its part

36、icularformulation. Sealant replacement needs to be considered andwhen needed should be easily accomplished.C1193 11a24.5 To assist the user of the guide in locating specificinformation, a detailed listing of guide numbered sections andtheir descriptors are included in Appendix X2.5. General Consider

37、ations5.1 GeneralProper selection and use of a sealant isfundamental to its ultimate performance, service life, anddurability. A sealant joint subjected to movement and othersimilar performance factors should be designed for the particu-lar application to avoid compromising its performance capa-bili

38、ty and causing failure (See 15). If not designed for theparticular application, failure is a distinct probability. Equallyimportant is the proper selection and use of other materials andproducts associated with sealant use. These include substratecleaner, surface conditioner or primer, type of seala

39、nt backingmaterial, bond-breaker, and joint filler, among others. Theability of a sealant installation to remain weathertight iscritically dependent on proper preparation, continuity, anddurability of the substrates to which the sealant will adhere,and compatibility of the sealant with the materials

40、 it willcontact, including the substrates. The proper application andinstallation of the various materials and products, following theestablished joint design criteria, avoids premature deteriorationof the sealant joint. For a sealant joint that is difficult orexpensive to access (for example, tall

41、buildings and certainroofs) a sealant should be selected that will have excellentenvironmental weathering characteristics to minimize mainte-nance. The following sections describe joint design guidelinesand the properties and use of a sealant and its associatedmaterials.5.2 DurabilityThe durability

42、of a sealant and a sealantjoint is related to many factors. For example, environmentalexposure to solar radiation, ozone, heat-aging, and atmosphericcontaminants can lessen sealant durability. Inadequate con-struction tolerances and improper sealant joint design formovement and other effects can con

43、tribute to sealant jointfailure, which is usually expressed as adhesive or cohesivefailure of the sealant. Inadequate installation (for example,where the sealant profile is inappropriate for movement, wheresubstrates have not been properly cleaned and, if required,primed, and the sealant inadequatel

44、y tooled, among others) isa common cause of failure. Conditions of exposure and design(where, for example, a sealant joint is exposed to constantwetting or to pedestrian or other traffic) can lessen sealant andsealant joint durability. The type of sealant, its primarypolymer backbone, and the partic

45、ular sealant formulation canalso contribute to lessened durability, especially if a sealant isused in an application, or under conditions of use, notappropriate for it. Frequently, various combinations of envi-ronmental exposure and conditions of use occur which canresult in lessened durability. For

46、 example, depending on sealanttype, joint movement combined with heat aging and coldweather exposure or joint movement combined with heat agingand moisture can result in failure. To enhance durability, it isimportant that the sealant type is matched to the conditions ofuse and exposure and that the

47、sealant joint is of proper designfor those conditions of use and exposure. In any event, eventualreplacement of a sealant that has reached its durability limitmust be planned for in the initial design and installation tofacilitate future remedial work.5.2.1 Durability TestingPresently, testing for s

48、ealant du-rability consists of exposing small-scale sealant samples toconditions intended to simulate the effects of movements (as inPractice C719), and to artificial weathering by actinic radiation,moisture, and heat, without cycling movement, in a laboratoryaccelerated weathering device according

49、to Practice C1442.Laboratory artificial weathering and heat aging can be useful inthe evaluation of the effects on sealants related to wash out,cracking, discoloration, and adhesion failure. The applicableASTM test methods are Test Method C732 for sealantsconforming to Specification C834, Test Method C1257 forsolvent release sealants conforming to C1311, and Test Meth-ods C792 and C793 for sealants conforming to SpecificationC920. Additionally, environmental exposure at various loca-tions (for example Florida, Arizona, Texas, and certain sites innorthern latitudes) is also co
