According to the "old school", of which I'm a charter member, veneering a substrate puts stress on it from the seasonal movement of the wood veneer, small as it may be. Therefore, you use a cheaper veneer on the other side to balance. Technically, you should even "counterbalance" plastic laminate, although no one does any more.
Spray water on, or apply a moisture-rich adhesive like hide glue to veneer on one side and watch it curl. When you use hide glue to veneer, you apply it to both sides, then scrape the glue off the face side after it dries.
That's why I am seeking a sprayed or brushed on coating, as much for the counterbalance effect as for sealing and sound damping.
