   Having experience in "floating" countertops, I'd think you would get a better job if you were to delete the sink opening until after the pour.

   This is what I suggest: scribe your sink cutout on the rough top. Roll out thick construction paper across the cutout. Lath the countertop right up to your scribe lines. Do your pour. After intial set, go back and clean up at the scribe lines, remove excess concrete, etc. next day, cut paper back to scribe lines.

   By deleting cutout until after pour you won't have to bother with the narrow width of countertop at the front and back of the sink when "rodding off" the pour. Also, your countertop will probably be more level--at least, flatter--at the sides of the cutout.

   For an undermount sink, make the cutout out slightly smaller (+/- 1/4" all sides) than the sink. Use 1 x material for sink support. Screw and glue the support strips to the underside of the roughtop. It WILL be sufficent to support the sink, water, full load of dishes, etc.

   Hi Folks,

   I'm considering pouring a concrete top with the sinks in place, right side up. Any hints or advices?
