The storm door is the first thing so it needs to appear great. The easiest way is to paint the door. It’s always important to prime before painting, but even more so when you are painting a metallic door, since paint will easily flake out unprimed metal. Both paint and primer amount readily on a surface that is horizontal, so you should take the door before painting. Spraying gives the best results, but you can get results using a paintbrush and the technique.
Remove by first unscrewing the door closer — if it’s one — using a screwdriver . Unscrew the door hinges, remove the door and put it flat on a pair of sawhorses.
Brush off loose dirt and dust, cobwebs using a clean paintbrush; then scrape off any loose paint. Wipe the metal using a rag moistened with denatured alcohol to remove the greasy film that metal surfaces get over time. Turn over when you have completed one side the door and wash the other hand in the exact same manner.
Cover both sides of any window or screen in the door with paper that is masking and painter’s tape. Create a line and then press firmly to prevent paint from seeping underneath it.
Dents with auto body filler. Scrape with a plastic putty knife; allow it place sand it using 100- to 150-grit sandpaper. Scuff-sand the remaining part of the door with 220-grit sandpaper, when all the dents are filled. Make sure you operate on both sides of the door.
Prime the door with metal primer. The easiest way is to spray the primer. Let the primer dry before turning over the door and spraying on the flip hand, which generally takes about ten minutes.
Spread a coat of paint on one side of this door. Latex paint using a brushuse a natural-bristle brush for oil-based paint. Stroke along the door’s length, like the door were made from wood, and you’re brushing with the grain. Wait two weeks for the paint subsequently turn the door over and paint the other hand.
Let the first coat of paint dry overnight, then scuff-sand it using sandpaper. Focus on areas having conspicuous brushstrokes and flatten them. Wipe the door using a damp rag to remove the sanding dust.
Spread another coat of paint that you spread the very first. Use the paint generously so it flows out and levels. 1 side of the door wait 24 hours.
