Shake a can of rust-inhibiting metal spray primer for the amount of time recommended by the manufacturer. Position the can the recommended distance away from the hinges -- it varies among manufacturers. Spray a light coat of primer on the hinges and screw heads using steady, even sweeps. Make sure you spray the sides and edges. Shake the can frequently while you spray. Allow the primer to dry for the amount of time recommended by the manufacturer. Apply a second coat of primer and allow it to dry completely.
Once you choose the style of hardware you want, it becomes easier to choose the right finish. There is a wide variety of cabinet hardware finishes: tarnished, polished, brushed, burnished, oil-rubbed, satin, antique or matte -- just to name a few. Stainless steel handles in a highly polished finish look great in a contemporary kitchen. Pewter and brass look more at home in a traditional setting. Bronze will patina over time, mature in appearance, and will make a bold statement in a kitchen. A black finish is dramatic on a light colored cabinet. Whatever you choose, just make sure the finish on your cabinet hardware complements the overall decor of your kitchen.
We also did that. Our handles are those stainless steel round bars. Loved the look with our white slab door/drawer fronts! Turned out there was big problem with sides of the horizontal drawer pulls snagging pants pockets. So, replaced those with centered flush type steel rectangular pulls that we mounted on the drawers after using router to make mortise holes No more snagging pockets!
Let’s talk first about metals. As a general rule, I like to keep the different metals in a kitchen to no more than two. If you have stainless steel appliances, that counts as one metal. So that leaves one other metal you can bring into a kitchen. If you’ve got brass light fixtures, that’s your one other metal. Your new hardware should be nickel or brass.
