Look over the entire painting for missing, loose, or crooked drills. Fix anything that needs attention before you seal the surface.
Use a brayer to gently press the drills firmly into the adhesive. If you don’t have a roller, place the protective sheet or parchment paper over the painting and carefully press across the surface.
Use a brush to spread an even coat over the entire diamond surface.
Work the Mod Podge gently across the drills and into the small spaces between them. You want coverage, but you don’t want huge puddles of sealer.
Look at the painting from several angles and smooth out any areas where too much Mod Podge has collected.
Pay special attention to the edges and spaces between drills. Brush away excess or add more.
Leave the diamond painting flat while it dries. Any cloudy appearance will disappear as the Mod Podge dries clear.
