GacoFlex LM60 Application

To waterproof the basin and supporting structures of the water sculpture, GacoFlex E5320 2-Part Epoxy Primer/Filler was spray-applied first to all surfaces and then GacoFlex LM60.

GacoFlex LM60 was installed to a thickness of 90 mils on horizontal surfaces and 60 mils on vertical surfaces to provide the most effective waterproofing membrane. Once GacoFlex LM60 was cured, the granite slabs and other decorative features were installed to complete the project.
