• Always check for leaks before starting.

3. Practice Your Technique

• When using your flat box, apply gentle pressure for a smoother finish.
• Practice on scrap drywall to find your comfort zone.

4. Cleaning Your Tools

• After each session, clean your box thoroughly to remove any leftover compound. This could extend its lifespan significantly.
• Make sure to store your box in a dry location to avoid moisture buildup.

Bonus Tip: If you’re looking to enhance your entire drywall setup, upgrading to a complete finishing set can be a solid move, especially if you’re switching from manual to automatic tools. If you’re starting out or want to upgrade your setup, this finishing set covers it all.
