Boud Microspheres, our pre-wetted Expancel® DET Microsphere blends, are used to create lightweight and workable fairing, filling and structural putties.

All you need to do is mix your chosen dust-free Boud Microspheres grade with your preferred epoxy or polyester resin to give a lightweight paste that’s easy to spread and shape. When you’re ready to sand your repaired surface, you will find that easier, with less dust being generated too.
