I am remodeling a home, and I installed a new laminate kitchen
countertop about 45 days ago that was 10 feet six inches long. Today I
noticed a small 1/8 of an inch crack in the 1.5 inch strip that goes
past the sinks that are installed in the countertop. (If one was
washing dishes, the crack would be by the dishwasher's belt and away
from the wall to which the counter was attached.) The kitchen has not
been in use while I have been remodeling. Does anyone have any idea as
to what could have caused the crack? Also, I doubt that there are any
workarounds to the problem (the crack is fairly noticeable because of
its location), if anyone has any ideas I would like to hear them
becauae of course, I am not interested in installing a new countertop.
I'd suspect a rough under-surface at the corner w/ perhaps a joint that
has moved slightly w/ time. Perhaps there's been some settling.
What type laminate/surface finish/color? I'm unaware of any real
patching technique for Formica-type laminates other than trying to match
surface color w/ tinted caulks, etc.
I'd be looking at the counter top mounting, etc., to try to determine
what went on as it may continue to move.
In that regard, what was the counter top material and how is it
The countertop was a Wilsonart Beige Pampas. Since I posted
to the group, I noticed that there was a slight bowing down where the
sinks were located. I think that and poor construction caused the
problem. However, there were no cracks in the counter--only the
laminate cracked. I did come up with a partial workaround. I had an
old countertop that was two inches two small, and I will be using it.
At the end where there will be a crack where it is joined with the
remnant of the old countertop, I will cover the counter with decorative
Thanks for your help.
Yes, laminates are brittle and in my experience Wilsonart is about the
<most> brittle of the various manufacturers I have used.
You found precisely the type of situation I suspected--insufficient
support at that weak point. When you install the other, be sure to have
adequate support all around and especially at force concentration points
such as the sink mount.
