The acrylic varnish matt is matter than matt. It is a great product. But buy small quantities as it does appear to deteriorate over time.

The polyurethane I have also found to be a very good varnish. Not quite as matt matt as the acrylic. Also takes a lot longer to dry and cure.

But it is much more resilient.
