I brushed on a thin coat of Interlux Schooner Varnish to my PMD interior (finally!) about 36 hours ago. It's still tacky. Temp in my garage range from 70 F at night to 95 F day. The varnish was a few years old, but unopened in its original container. I stirred it well, and did not thin it.
Is it normal for varnish to take so long to dry?
Dare I use more of this can, or should I chuck it and get a new one?
