Adhesive for attaching sink to granite worktop

Fraqus, A lot of granite companys do'nt like to use the clips that come with an undermount sink. For some reason thet are not happy about drilling the granite,

They company that i use prefers me to build a framework within the sinkbase to "carry" the sink. Then the top surface of the sink is flush with the underside of the granite.

I believe the sealant they use is a silicone one.

Hope this is of some help.

Yup! Build a support frame and silicon in place.

 

I normally fit a18mm ply panel to make the top of the unit solid (if it isn't already). Mark around the sink and cut About 10mm in. Work top just drop over. Granite fitters I know just use silcone to seal. I am sure i read on here once that a g/fitter just silconed the sink in and once set, climbed onto the tops and stood in the sink to prove it could hold a sink full of water.
