I’m going to build a concrete counter top using formica mold method. I have a “left over” tile in sink & am wondering about putting the sink in place and then my concrete. Or put sink in later and grout as if it were a tile counter?
Has anyone tried this or have any thoughts to spare? I know it ain’t gonna make it any easier to install the finished product, but will it work?
When is the guy writing the “Everything you ever wanted to know about concrete countertops” book going to be finished? Joe H

Joe , That is what I plan on doing . I was thinking of inveting the sink on the mold ,ducttape the edges and wrap the tape on the flanges and on up the sides of the sink . Then pour and remove when cured . Or raise the sink about 1/2" with blocking so i could have a grooved drain board.
*Don, my intention is to have the sink as a permanent piece with the counter. No tape, I don't want a gap to grout or caulk. This type sink is meant to be flush with surrounding tile, there is no enamel on the edge. It is grouted in when the counter is grouted. My question is will the concrete stick to it or not. Is it going to pull back and leave a gap? I would hate like hell to have to ruin the whole thing, I've learned waaaaay to many things that way already. Joe H
*Here's a wacky idea. Why not skip your left over sink all together and create the sink out of concrete?I don't know how smooth the backside of your sink is, but why not use it as part of the mold to create a one piece built in concrete sink? If it's good enough for counters, it should be good enough for sinks.
*Scott has an idea there. Joe, most sinks have a coating of some sort on the backs , I think if you sand blast the back side and the edge the concrete will stick . Forming the sink into the counter would make a better job now that you explain it that way. Damn concrete stiks to every thing it spaters on. About Scotts idea , I think that you could make a ss sink the form for a poured in place concrete sink. The sound deadner should come off with laquer thinner or brakekleener. Then a little carefull grinding and you should be set.
