   Yes, You can apply new laminate over old. You need to ensure that the old laminate is securely glued to the substrata. Any delamination from the substrata will cause the old laminate to "bubble" and lift when the new piece is placed.
   Rough the old laminate surface up using sandpaper, lightly but uniformly scratch it with maybe 100-150 grit. Vacuum clean and wipe with tack cloth. Installation of the new is the standard procedure, apply the usual contact adhesive to both surfaces and away you go.

   Edited to change the grit size. I meant to type 100-150, not the 150-180 I had posted.

   Had a counter top guy redo counters in the house I have now......old had burns.

   He belt sanded it first, then as said before, used the usual contact cenemt.

   Two years so far......no probs yet.

   I've heard conflicting reports on the effectiveness and longetvity of laminate over laminate.

   I've never put new over old but imagine I might feel better about stripping off old and then applying new.

   However, if I were in the mood to try resufacing the old, I would certainly scuff the old surfaces very well first.

   i do this quite  often,clean the old with scouring pad and soap or thinner. i use a random orbit sander with 100 grit,have used a belt sander also to rough it up. clean it and put contact on surface,it will take just a little longer to tack though. larry

   hand me the chainsaw, i need to trim the casing just a hair.

   I've also glued & nailed 3/8" or 1/2" PB on top of old decks when it's impossible to remove them for whatever reason. End up with a thick edge, but some kinda like the way that looks.

   Everything will be okay in the end.  If it's not okay, it's not the end.

   Cnosider whether the thicker surface will be a problem fitting under backsplashes, trim, etc. You can remove the laminate with a heat gun to soften the adhesive, too, and relaminate the old surface...done that successfully.

   And you can use your wifes best steam iron, set on cotton without steam.  Works great, right up until she sees what you're doing.
