Significance and Use4.1 This guide provides information and guidelines for consideration by the designer or applicator of a joint seal. It explainsthe

30、properties and functions of various materials, such as sealant, sealant backing, and primer, among others; and, procedures suchas, substrate cleaning and priming, and installation of the components of a sealed joint. It presents guidelines for the use andapplication of the various materials, design

31、of a sealant joint for a specific application, and environmental conditions and effectsthat are known to detrimentally affect a sealant joint. The information and guidelines are also useful for those that supplyaccessories to the sealant industry and for those that install sealants and accessory mat

32、erials associated with sealant use.C1193 1624.2 In addition to the design and installation data in this guide, consult the sealant manufacturer about applications for itsproducts and their proper use and installation. Considering the range of properties of commercially available sealants, the variet

33、yof joint designs possible, and the many conditions of use, the information contained herein is general in nature.4.3 It should be realized that a sealant and sealant joint are expected to have a design life during which they remain functional.However, a sealant and sealant joint will also have a se

34、rvice life. The intent is for service life to meet or exceed design life. Thereare many factors that can affect service life including type of sealant polymer, sealant formulation, compatibility with adjacentmaterials, installation techniques or deficiencies, sealant joint design (or lack thereof),

35、proper maintenance (or lack thereof), andenvironmental exposure, among others. The designer of a joint seal should take the above into consideration when designing andspecifying sealants for certain applications.4.4 The design life of a sealant or sealant joint should be considered in conjunction wi

36、th the design life of the structure for whichit is used. For example, a building owner may require a new courthouse building to have an expected design life of 50 years.Therefore, elements of the buildings exterior envelope should, with proper maintenance, be expected to perform for that timeperiod.

37、As a result of the information in 4.3 it should be realized that a sealant or sealant joint may not perform for that time periodwithout proper maintenance. Proper maintenance could include replacement of localized sealant and sealant joint failures andconceivably complete sealant replacement, perhap

38、s more than once, during that 50 year time period depending on a sealantspolymer base and its particular formulation. Sealant replacement needs to be considered and when needed should be easilyaccomplished.4.5 To assist the user of the guide in locating specific information, a detailed listing of gu

39、ide numbered sections and theirdescriptors are included in Appendix X1.5. General Considerations5.1 GeneralProper selection and use of a sealant is fundamental to its ultimate performance, service life, durability, anddurability.sustainability. A sealant joint subjected to movement and other similar

40、 performance factors should be designed for theparticular application to avoid compromising its the sealants performance capability and causing failure of the sealant (See 15).If not designed for the particular application, failure is a distinct probability. Equally importantpossibility. Of equal im

41、portance isthe proper selection and use of other materials and products associated with sealant use. These include substrate cleaner, surfaceconditioner or primer, type of sealant backing material, bond-breaker, and joint filler, among others. The ability of a sealantinstallation to remain weatherti

42、ght is critically dependent on proper preparation, continuity, and durability of the substrates towhich the sealant will adhere, and compatibility of the sealant with the materials it will contact, including the substrates.The properapplication and installation of the various sealant materials and p

43、roducts, following the established joint design criteria, avoidspremature deterioration of the sealant joint. is fundamental to realizing the intended service life of the sealant. For a sealant jointthat is difficult or expensive to access (for example, tall buildings and certain roofs) a sealant sh

44、ould be selected that will haveexcellent environmental weathering characteristics to minimize maintenance. The following sections describe joint designguidelines and the properties and use of a sealant and its associated materials.provides the optimum combination of performancecharacteristics (for e

45、xample, adhesion, movement capability and resistnce to environmental conditions) appropriate for thatapplication.5.2 DurabilityThe durability of a sealant and a sealant joint is related to many factors. For example, environmental exposureto solar radiation, ozone, heat-aging, and atmospheric contami

46、nants can lessen sealant durability. Inadequate constructiontolerances and improper sealant joint design for movement and other effects can contribute to sealant joint failure, which is usuallyexpressed as adhesive or cohesive failure of the sealant. Inadequate installation (for example, where the s

47、ealant profile isinappropriate for movement, where substrates have not been properly cleaned and, if required, primed, and the sealant inadequatelytooled, among others) is a common cause of failure. Conditions of exposure and design (where, for example, a sealant joint isexposed to constant wetting

48、or to pedestrian or other traffic) can lessen sealant and sealant joint durability. The type of sealant, itsprimary polymer backbone, and the particular sealant formulation can also contribute to lessened durability, especially if a sealantis used in an application, or under conditions of use, not a

49、ppropriate for it. Frequently, various combinations of environmentalexposure and conditions of use occur which can result in lessened durability. For example, depending on sealant type, jointmovement combined with heat aging and cold weather exposure or joint movement combined with heat aging and moisture canresult in failure. To enhance durability, it is important that the sealant type is matched to the conditions of use and exposure andthat the sealant joint is of proper design for those conditions of use and exposure. In any event, eventual replacement of a sealantthat
