Vapor Retarder Primer TA

Vapor Retarder Primer TA is a blend of bitumen and solvents

Vapor Retarder Primer TA is a blend of bitumen and solvents used on concrete decks prior to applying Sika’s torch-applied vapor retarders. The primer improves the attachment of Sika’s torch-applied vapor retarders to the properly prepared and fully dry concrete surface. It is also used to prime concrete decks prior to the application of hot asphalt for Sika’s ply sheets.

  • Enhanced adhesion strength between primed substrates and Sika’s torch-applied vapor retarders or hot asphalt.
