Have to make sure it's done in a shady area outside, little to no wind day, sprayed evenly from about 10-12 inches from surface. It dries quickly, and I usually give small items, such as those pictured in OP, 2-4 coats (each surface one time, then respray surfaces in same sequence until sealed.) For larger items, such as the cabinet am working on, once decoupaged, crackled and stained, gets 4-8 coats, especially the top surface as that area gets the most use.
Current project:
Inset areas of cabinet and its doors will be decoupaged, as well as the drawer front. Top is gold; haven't decided on color for interior of cabinet yet. Other paint is a dual combo of colors.
What I started with:

In Progress:
(a base coat of acrylic color so as decoupage pieces are applied, there is color underneath for any bare spot that may show through, as well as color that "shines through" any of the paper)
The cabinet
Looks a bit bright here, but it's actually a little bit darker. Once crackled and age darkened, it wil have a very rich look.

The base color of the doors and drawer
Outside framing and backside of doors are getting gold paint.
