Removing air bubbles from dried Mod Podge?

To remove air bubbles from dried Mod Podge, gently sand the surface with fine-grit sandpaper to smooth out any imperfections. If the bubbles are still present, you can apply a thin layer of Mod Podge over the area, ensuring to brush it out smoothly to eliminate any new bubbles. For best results, work in a well-ventilated area and consider using a heat gun or hairdryer on a low setting to help release any trapped air. Always allow sufficient drying time between layers for optimal results.
