I'm painting construction grade lumber black using Krylon Fusion. The directions say "apply additional coats within 2 hours or after 48 hours." I had some things to do and missed the 2 hour mark by a few hours. Do I really have to wait 48 hours to give it a second coat? I'm in AZ the pieces were out in this dry climate all day. I plan on put a few coats of clear satin spray spar urethane on the pieces if that makes a difference.
Thanks in advance.
