I have to install a ceramic undercounter sink to a marble countertop.
manufacturer has supplied 4 brass inserts that are to be drilled & epoxied in place to attatch metal clips.
My question, what kind of adhesive do I use to attatch sink to countertop.
This is a first for me, what else should I know.
Many thanks Dennis [email protected]

This is where I recommend 100% silicon for the sink to countertop.
Marble can be soft, so be careful with the brass inserts.
With your limited experience with stone, you might want to instead consider a couple of cleats, one screwed into each side of the cabinet under the sink, and use those to support the side flanges of the sink. That'll keep you from messing with the marble.
If the cabinet is too wide compared to the width of the sink, you can use left-to-right running cleats to support the front and back flanges of the sink, and attach the ends of those cleats to the cabinet sidewalls.
Since this is your first time, consider dry fitting everything with no silicon. Set the sink and screw in the cleats, make sure everything is tight.
If working solo you can cut a couple of support pieces that look like inverted "T"s, with the long leg just long enough to hold the sink tight to the underside of the countertop. If you have a helper they could be above and help align the sink with the opening in the countertop for equal reveal.
Once you feel comfortable, take it all apart, then run a bead of silicon on the flange of the sink, and then install it for good.
