Problem with RR delamination

Aloha, Just glassed my latest creation with RR #2000.  It is a US red blank with a 6oz on the bottom and a 6oz plus a 6oz deck patch on the deck.  The bottom went great and the next day I glassed the deck and thought it looked pretty good, went to lunch and when I came back there was lots of delam under the deck patch the rest of the deck is fine. Any ideas? I would appreciate your help so it does not happen next time.

you mean air?

if your room heats up during cure, air escapes, creating bubbles in lam

lam on falling temp or in a steady temperature...

lunch in spain is warmes time, right?
