When you're ready to hammer and nail in trim, you'll want to protect where those nails go in. Today in this episode of more "saving face," we tell you how to put a shield in place. When nailing decorative molding or any type of milled woodwork or painted trim, don't let a misguided hammer blow ruin the surface. Instead protect it with a simple homemade shield. To protect decorative trim from wayward hammer strikes, cut a piece of pegboard a few inches square. Then start the nail in with a few light taps. Slip one of the holes in the pegboard shield over the nail head, and hammer away with gusto. You can do this without fear of damage should your aim waver a tad. Once you've driven a nail as far in as possible, lift off the shield and finish the job with a nailset. No hits, no runs, no errors. And that's the On The House tip for today.
