Repairing cracks
Posted: Thu Apr 19, 2012 12:37 pm
I got two calls recently to look at some cracked tops. So, I visited the homes yesterday and the symptoms are exactly the same. Un-rodded cutouts (drop in stove and sink) and unsupported (no shims) edge. One kitchen had the some of the best seams I've ever seen. One seam was in the middle of the stove cut-out. However, the crack is to one side of the seam. Which, in turn, has broken the almost perfect seam. The seam was not rodded and the cracked side had visible air space between the stone and the cabinet. The second kitchen had the worst seams I've ever seen and the sink cutout was terribly overcut and misplaced. In fact the front edge had only an inch and a half of stone from the cutout to the edge. Besides that, the sink was not rodded and lacking in any support between the stone and the cabinet as well. And, the stone was cracked near the backsplash behind the sink.
So, on to figuring out the repair. The first one is already loose enough that it will probably just fall out when the silicone around the cabinet face is cut. Clean up the epoxy in the seam, add new epoxy, replace piece, and finish.
The second one however is severely cracked on the right side of the sink and has a hairline fissure on the left. I believe that trying to do the same thing as the first will not result in the same outcome. I suspect that the cracks will lead to breakage if any attempt is made to remove the piece. I recommended that they replace the whole top. But as a temporary fix, I was hoping to add supports to the edge and add some type (not sure what type) of flowing adhesive to the major crack to stabilize it for awhile.
Has anyone out there tried this or has any suggestions?
Many thanks ....
