We are trying to install a drop in Blanco Silgranit sink... hole is cut and sink fits well but it leaves about an 1/8" gap all around, not sitting flush to the counter.
Any ideas how to fix this?
We bought the sink at a Rona store closing so no box, instructions or template...
Thanks.
Sounds like there is a curve in the bowl under the lip, and the cutout needs to be just a hair bigger.
But don't count on that!
Turn the sink over and measure and allow for any curve.
Also hold it up in front of you and look for warping. That won't be easy to deal with.
If that's the case, you will have to put extra clips all around and maybe weigh it down with concrete blocks over a large board.
Thank you for the idea... it appears there is a manufactured shape difference between the extreme outside edge of the sink and in closer to the edge of the bowl but if we cut the hole bigger it would only leave about 1/2" holding above the counter.....the sink is very heavy and we're afraid to cut it out in case the counter isn't strong enough to hold it!
Is there such a thing as a gasket of some sort to place all the way around the edge to take up that 1/2" all the way around the sink? An 1/8" thickness tape maybe that is water proof?
Thanks again in advance!
What do you mean exactly by a manufactured shape?
If it's a curve, it's OK to shave another small amount all around, starting with 1/16.
1/2" is standard for a lip.
You don't really want it raised up with a gasket for appearance sake and for cleaning around the edge, although feel free to do so. I don't know what product you would buy. You'd have to make one. You could use the material used for showers. It's usually orange, expensive, and comes in large pieces. You could look for any place that sells neoprene, the material used in all sorts of things from gaskets to wetsuits.
I'd just shave off 1/16" and see if it fits.
If it's an shape that's half way out from the bowl, you might have an undermount sink, or it's just the normal clip edge for a topmount sink. Can you take a picture?
If the sink didn't come with clips you can purchase some here:
Blanco Silgranit Sink Clips at Kaboodle
Next, you need to purchase and squeeze some silicone caulking into the channel around the underside of the sink, install and tighten the clips (should pull the sink pretty tightly down to the counter) and then clean any excess silicone with mineral spirits or rubbing alcohol.
Finally, if the sink is a composite material and you have no clips available, you would not use concrete blocks to pull the sink down, you would use wood to span the sink and then wood to span an equal width up against the ceiling and then you would install some 2"x4' studs from ceiling to sink and bang them lightly into place until you see the sink suck down. Leave overnight and then remove the studs and spanning wood and you should be all set here.
If the sink is a granite composite it may not bend in any way and then you may have to simply install the silicone to the underside of the sink and install it... gap will fill in so it will be easy to clean and if you use a clear silicone it will reflect the color of the sink well and that should leave a nicely finished result here!
Good luck!

Thank you Mark... I think we have it now... it is a drop in sink so that clip wouldn't work for us but we are doing the silicone around the edge... the weight of the sink will hold it in I think... you have all been most helpful! And we appreciate your time!Quote:

Those 80% granite sinks have a huge allowance across the width for clips, at least on the 33" one I just looked at.
So it really sounds like you need to cut the hole bigger.
33" x 22" sink requires a 31 1/4" x 21 1/4" cutout.
Weight shouldn't be a problem.
I can probably find the spec page for you.
Drop in sinks do NOT use clips, Joypulv, but they can be forced down as I presented above.
It sounds like they are all set here!
OK! All the ones of that brand I looked at just said 'clips sold separately.'
Looks like we've got it in, siliconed and waiting our requisite time for it to dry... alterations to the pipes have been made... tried the water and it's flowing the right way! ha ha... all good and we thank you both for your help and ideas.Quote:
