Don’t manipulate a pastry sheet that’s not fully thawed as this could lead to the sheet tearing.
If the pastry sheet doesn’t fold easily after coming out of the microwave, place it back in on “high” for another 5 seconds on each side. Keep microwaving for 5 seconds on each side until the pastry sheet folds easily.
If the pastry sheet can be folded easily but feels warm to the touch, you should place the pastry sheets in the fridge to cool them instead of thawing them.
If you can, they are ready to be used. If you still feel like the pastry sheets are frozen, leave them in the fridge for another hour. After the 4 hours are up, check to see how easy it is to fold the pastry. They should be fully thawed at this point and ready for use.
If they’ve thawed but now feel like they’re at room temperature, place the sheets in the fridge for 10 minutes to give them time to become cool.
