Im having a granite worktop with under mount sink installed and the installers are suggesting silicone sealant left to cure for 48 hours is sufficient to support the sink. I've read a few tales of sinks dropping out after a few years so thought I'd make up some supports. I'm thinking of attaching battens to the carcus to provide some strapping, but wondered if anyone has done this and has any tips. I won't be able to start until after the install so will be limited in access.
