Not mine, up to 13x18.  Maybe you are using thinner paper. I'm assuming
you do NOT mean "waves" in the paper that sometimes appear in a print as
it comes off the printer. This isn't what I was referring to. That is
almost certainly caused by a combination of too thin paper and high humidity.

What else could cause buckles than humidity, unless they came off the
printer buckled.  (not wavy). Ordinary typing paper buckles and waves
terribly, but not 300 gsm papers.

How can one tell when one is dry mounting whether he is doing it
incorrectly?  If you follow the directions, you follow the directions.
As long as you pre heat the paper and matte board, and use a high enough
but not too high temperature,  and use the time the mounting paper
specifies, what else can you do?
