Analysis of many sealant joint failures indicates that the majority of failures can be attributed to improper joint preparation and deficient installation of the sealant and various joint components. The following ASTM guidelines describe several aspects that should be considered when applying sealants in unprotected environments to achieve a durable application:
- ASTM C1193, “Standard Specification for Use of Joint Sealants”,
- ASTM C1299, “Standard Guide for Use in Selection of Liquid-Applied Sealants”, and
- ASTM C1472, “Standard Guide for Calculating Movement and Other Effects When Establishing Sealant Joint Width”.
The sealant manufacturer’s literature should always be consulted for recommended procedures and materials.
