SIGNIFICANCE AND USE 4.1 This guide provides information and guidelines for consideration by the designer or applicator of a joint seal. It explains the properties and functions of various materials, such as sealant, sealant backing, and primer, among others; and, procedures such as, substrate cleaning and priming, and installation of the components of a sealed joint. It presents guidelines for the use and application of the various materials, design of a sealant joint for a specific application, and environmental conditions and effects that are known to detrimentally affect a sealant joint. The information and guidelines are also useful for those that supply accessories to the sealant industry and for those that install sealants and accessory materials associated with sealant use. 4.2 In addition to the design and installation data in this guide, consult the sealant manufacturer about applications for its products and their proper use and installation. Considering the range of properties of commercially available sealants, the variety of 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 service life. The intent is for service life to meet or exceed design life. There are many factors that can affect service life including type of sealant polymer, sealant formulation, compatibility with adjacent materials, installation techniques or deficiencies, sealant joint design (or lack thereof), proper maintenance (or lack thereof), and environmental exposure, among others. The designer of a joint seal should take the above into consideration when designing and specifying sealants for certain applications. 4.4 The design life of a sealant or sealant joint should be considered in conjunction with the design life of the structure for which it is us... SCOPE 1.1 This guide describes the use of a cold liquid-applied sealant for joint sealing applications. Including joints on buildings and related adjacent areas, such as plazas, decks, and pavements for vehicular or pedestrian use, and types of construction other than highways and airfield pavements and bridges. Information in this guide is primarily applicable to a single and multi-component, cold liquid-applied joint sealant and secondarily to a precured sealant when used with a properly prepared joint opening and substrate surfaces. 1.2 An elastomeric or non-elastomeric sealant described by this guide should meet the requirements of Specification C834, C920, or C1311. 1.3 This guide does not provide information or guidelines for the use of a sealant in a structural sealant glazing application. Guide C1401 should be consulted for this information. Additionally, it also does not provide information or guidelines for the use of a sealant in an insulating glass unit edge seal used in a structural sealant glazing application. Guide C1249 should be consulted for this information. 1.4 Practice C919 should be consulted for information and guidelines for the use of a sealant in an application where an acoustic joint seal is required. 1.5 This guide also does not provide information relative to the numerous types of sealant that are available nor specific generic sealant properties, such as hardness, tack-free time, or curing process, among others. 1.6 The values stated in SI units are to be regarded as the standard. The values given in parenthesis are provided for information only. 1.7 The Committee with jurisdiction for this standard is not aware of any comparable standards published by other organizations. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and e...
Abstract
Overview
ASTM C1193-16(2023), Standard Guide for Use of Joint Sealants, is an authoritative guide developed by ASTM International to provide crucial information on the selection, design, and application of cold liquid-applied and pre-cured joint sealants. This guide is widely utilized in the construction, architectural, and civil engineering sectors to ensure high standards in sealing joints found in buildings, plazas, decks, and pavements for both vehicular and pedestrian use. It outlines best practices for substrate preparation, sealant selection, and installation, highlighting the diverse environmental and operational factors that influence joint sealant performance.
Key Topics
-
Sealant Types and Materials The guide covers both elastomeric and non-elastomeric sealants that should conform to ASTM C834, C920, or C1311. It distinguishes between cold liquid-applied sealants (single and multi-component) and pre-cured sealants when correctly matched with prepared substrates.
-
Substrate Preparation Proper cleaning, priming, and surface conditioning are emphasized to ensure optimum adhesion and longevity. The compatibility of the sealant with adjacent materials and the importance of using appropriate joint backers and primers are key focuses.
-
Joint Design and Installation Recommendations for joint design center on accommodating expected movement, environmental exposure, and maintenance needs. Considerations include the width and depth of the joint, sealant profile, and access for future repair or replacement.
-
Durability, Service Life, and Maintenance The guide highlights the need to match the sealant’s design life with that of the host structure and addresses the impact of environmental factors (UV exposure, temperature cycling, moisture, pollutants) and installation deficiencies on performance and longevity.
-
Testing and Performance Evaluation Key performance indicators such as adhesion, compatibility, color stability, and resistance to staining are addressed. The guide refers to ASTM test methods (e.g., C719, C1087, and C1247) to evaluate these properties under accelerated and real-world conditions.
Applications
ASTM C1193-16(2023) is applicable to a wide variety of construction and maintenance situations where joint sealing is critical for durability and weather resistance. Typical applications include:
- Sealing joints in building exteriors, such as façades, windows, and expansion joints
- Waterproofing horizontal surfaces like decks, plazas, and sidewalks
- Protecting pavements used for vehicle or pedestrian traffic from water ingress
- Ensuring long-term adhesion in complex or inaccessible locations, including roofs and tall structural elements
- Maintaining optimal acoustic, thermal, and environmental performance in building envelopes
The guidance within ASTM C1193 assists professionals in selecting the right product, preparing surfaces, and installing sealants to maximize joint longevity, minimize failures, and plan for effective maintenance and remedial action.

Note: This guide does not cover sealant use for structural sealant glazing or insulating glass unit edge seals (refer to C1401 and C1249, respectively), nor does it address detailed technical properties like cure time or hardness.
By establishing best practices for joint sealant usage, ASTM C1193-16(2023) serves as an indispensable resource for designers, applicators, and material suppliers looking to optimize the performance and reliability of sealed joints in modern construction. Incorporating these guidelines not only extends service life but also reduces the costs and risks associated with premature sealant failure.
