Polyurethane-based sealants
VOC emission testing (tests in emission chamber, as per CDPH Standard Method v1.1 - 2010) by third-party laboratory is underway. Here are the products that have already been tested and that currently meet the requirements of this credit (tests results available upon request)
Note: Testing is currently underway for other Sika flooring products. Test results are expected August/September 2018. In the meantime, we do invite you to contact Sika Canada for additional information.
