Laminate over laminate on kitchen counter?
I'm getting new laminate on my kitchen counters. The old are "okay" not torn up or dinged but they are 20-odd-years old and in need of a face lift. So, for a variety of reasons, I'm going with a new laminate and plan to have a contractor do the work. This is just a straightforward counter, no special edges. My contractor came out, measured then sent me a bid and on the bid it stated that they would be laying new laminate over the old.
My understanding is that it is best to take off and then have the new laid on. I've emailed him asking about it and am waiting for the reply but wondered if any of you have laid new laminate over old? Just doesn't seem right to me.
