A little tip for you, if you like to veneer over melamine, as in my case when I wanted melamine interior (inside of cabinet doors to match interior of entertainment center), but exotic veneer exterior of cabinet. Use PL Premium polyurethane construction adhesive - works like a dream for several reasons: First off, PL bonds to melamine / HPL surfaces as a literal weld - never in my 30 years of gluing with PL to melamine, have I ever had it come off without abrading it off. No need to sand the melamine at all.
Second, is that the PL is solventless, so no shrink, which is what causes most warping during cure. Third, even though its high viscosity (pumped out of caulk gun), it rolls out great with rubber brayer roller. Even coat, and need to err on side of too little, because it expands as it cures. The viscosity also helps so it does not seep through pores. I veneered Pommele Sapele (open pore) and no bleed through. Then I sealed with epoxy, sanded, then topcoated with Auto urethane, then buffed. Still looks awesome to this day.
