- 1). Brush on a coat of liquid sander to the surface of the siding with a stiff bristle broom. Work in small sections and cover the entire surface. Let the sander stand for a few minutes then brush back over the surface to remove it. This will break down oil based stain or sealers to allow the primer to stick. Allow the siding to dry.
- 2). Mix auto-body-filler-epoxy ten parts putty to one part activator to fill any cracks, nail holes or other dents and dings in the siding. Spread the putty with a metal putty knife. Smooth it even with the face of the siding. Allow it to harden and sand the putty to even it out with a random orbit sander and 100 grit paper.
- 3). Roll a coat of oil based binding primer on the siding. Use a brush to apply the primer to any cracks or seams in the siding. Work in small sections applying the primer as evenly as possible. Be careful to prevent runs or drips in the primer which can cause unevenness in the finished paint. Allow at least two hours drying time.
- 4). Sand the siding lightly with a pole sander to smooth any grain that was raised in the priming process. Rub over the surface with a tackcloth stretched over the pole sander pad to remove sanding dust.
- 5). Mix your paint well if it has been more than a few hours since it was mixed by the retailer. Mix paint from single gallon cans together in a larger container, such as a five gallon bucket to ensure even color.
- 6). Roll on at least two coats of oil based paint. Allow the label-recommended drying time between coats. Sand lightly or polish with 0000-steel-wool between coats for the smoothest finish. Follow up with a pass of the tackcloth to keep the surface dust free. Leave the last coat unsanded.
