In addition, the same forces (tensile stresses at the bondline and within the cured sealant) that will cause the outer installation to fail, will also likely cause the inner installation to fail as well. Backerseal works in compression providing a practical-to-install, fully functional secondary joint sealant using different performance principles than the primary, liquid sealant. In addition Backerseal provides insulation and sound attenuation value as well as the ability to resist the effects of air-pressure differentials.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Secondary sealant to liquid sealants for joints in walls A joint sealant for building walls and wall systems, Backerseal is an economical, precompressed, secondary joint sealant to field-applied caulking.
