Fresh paint coating can make your metal spiral staircase look like new. To paint your metal spiral staircase, here is what you need to do.

Step 1 – Protect the Floor, Furniture and Fixture near the Staircase

Before you do any paintwork, push all movable furniture away from the staircase to avoid accidentally splashing paint on them. Also, you need to wrap the floor, furniture and fixture near your staircase with old newspapers to protect them from paint stains. Use thicker wads of old newspapers to protect the floor area which is directly under the spiral staircase. Use water based transparent adhesives to secure the wrapping on your floor, furniture and fixture. Water base adhesives are easier to remove compared to other types of adhesives and they do not cost much.

Step 2 - Remove the Old Paint and Corrosion

Before applying new paint on your metal spiral staircase, you need to remove the old paint first. When removing the old paint, start at the top of the spiral staircase then methodically work your way down. This way, you will less likely to miss hard to reach areas. To remove the outer paint, use 80-grit sandpaper then use a 200 grit sandpaper to remove the scratches on the metal.  To smooth out the surface of the metal, use 400-grit sandpaper. See to it that the metal surface has a fine finish before you stop sanding.

When sanding your metal spiral staircase, pay close attention to areas showing signs of corrosion. Sand these areas carefully and make sure that you remove all the corrosion. If an area in your metal spiral staircase is so badly corroded, sanding the area may not be enough to remove the corrosion. In this case, you need to replace the metal parts.  To replace the badly corroded parts of your metal staircase, use a metal cutter to cut the area out then attach the new parts to the staircase using a soldering gun. Make sure that the new metal parts match with the rest of the metal spiral staircase.  After soldering the new parts into the staircase, sand the area carefully to achieve a fine finish.

Step 3 - Clean Your Metal Staircase

After removing all the paint and replacing corroded parts of your spiral staircase, clean the area thoroughly. When cleaning your staircase, start at the top of the stairs and work your way towards the bottom. Rub the surface of the metal using a damp old rag then use an old paintbrush to clean-off hard to reach areas. Make sure that you remove all particles from the surface of the metal to avoid causing bubbles on your paint later on.
