When applying Mod Podge over a design, apply one layer of the Mod Podge with side-to-side brush strokes. Allow that coat to dry for 20 minutes or so before applying another even layer of Mod Podge in up-and-down strokes. I have found that this process results in the smoothest possible finished surface.

How do I get a smooth finish with Mod Podge?

For an ultra smooth surface, apply 4 to 5 coats of Mod Podge Hard Coat. When applying the coats, brush in one direction then the other and let dry between coats. Wet sand with #400 sandpaper and water. Sand finish lightly until ridges are flat and smooth.

Do you need to seal over Mod Podge?

Do you need to seal Mod Podge? No, you do not need to seal Mod Podge. It is a glue, sealer, and finish all in one. The Mod Podge Hard Coat in particular has very tough properties that make it suitable for sealing furniture.
