SWR Institute Launches Pre-Cured Sealant Validation Program

Share Article

The Sealant, Waterproofing and Restoration Institute (SWR Institute) launched a new program to validate the manufacturer’s published test results of various pre-cured sealants. The program provides specifiers and end-users of pre-cured sealants an unbiased method to judge whether pre-cured sealants will perform at the levels of the manufacturer’s published data sheet for that particular product.

The Sealant, Waterproofing and Restoration Institute (SWR Institute) launched a new program to validate the manufacturer’s published test results of various pre-cured sealants.

The program provides specifiers and end-users of pre-cured sealants an unbiased method to judge whether pre-cured sealants will perform at the levels of the manufacturer’s published data sheet for that particular product.

Frank Halsey, chair of the SWR Institute Validation Committee, said the Institute is extremely excited to offer a third validation program in addition to its Wall Coating and Sealant Validation Programs. “The new validation program gives end-users the confidence they need when specifying a pre-cured sealant. Since the program is voluntary and the companies involved use independent labs to perform the tests, we hope those purchasing the products will feel more confident about what they are buying.”

The new Pre-cured Sealant Validation Program is the third validation program to be offered by SWR Institute. The Sealant Validation Program was established in 1995 and the Wall Coating Validation Program launched in 2003.

Manufacturers who wish to participate in any of the validation programs simply choose an independent laboratory from a list provided by SWR Institute. Once a lab is chosen, the manufacturer provides it with the name of the product to be tested as well as a current manufacturer data sheet with the stated performance characteristics, test results and any other collateral materials. The third-party lab will randomly purchase the product being tested from a retailer. Using the information provided by the manufacturer, the lab will test the product to the greatest claim made on the manufacturer’s data sheet.

Specifically, the tests performed for the required pre-cured sealant validation include the following ASTM tests:

1. C 1523 Standard Test Method for Determining Modulus, Tear and Adhesion Properties of Pre-cured Elastomeric Joint Sealants. Test must be performed to validate the greatest joint movement capability and tear propagation properties claimed on the Manufacturer’s data sheet.

2. D 412 Standard Test Methods for Vulcanized Rubber and Thermoplastic Elastomers-Tension. Test must be performed to validate the ultimate elongation at break as claimed on the manufacturers data sheet.

Once the product passes the tests, the manufacturer may apply to SWR Institute for a validation number and seal. Each validated product has a term of five years from the date of validation.
