Understanding Quarter Round Molding
Quarter round molding is a small, rounded trim piece typically used to cover the gap between the wall and the floor. It's a simple yet effective way to add a touch of elegance and protect your walls from damage. To install quarter round, you'll need a nail gun and the right nails.
Choosing the Right Nail Gun
Before discussing the nails, let's briefly talk about the nail gun. For quarter round, a Brad Nailer or a Finish Nailer with 15-18 gauge nails is usually the best choice. These guns drive thin, small nails that are perfect for trim work and won't split the wood.
