I am getting ready to paint my house, but I have some rusty nails throughout the wood. How do I prevent rusting nails from staining or showing through?
If nails have rusted and stained the exterior wood in the past, they’ll do it again unless you guard against it. To prevent repeat rusting, sand the rusting nail heads, then sink them below the surface of the wood. Next, seal them with a sealer, a primer-sealer or a primer that contains rust inhibitors. Finally, fill in the dent with putty and surrounding wood to create a smooth, continuous surface.
