Polish the entire galvanized steel surface especially rough places such as crevices and dents.
Process for painting galvanized steel. T wash etch primers sweep blasting and weathering. All you need to do is apply the vinegar on. Galvanized steel is the go-to solution for blocking the process of rusting for iron and steel.
Galvanizing is an effective low-cost way to improve the durability of bare steel resulting in a surface finish that is more durable than paint alone yet accepts paint as an additional layer of protection. Otherwise the surface may look like it was painted by an amateur painter. Galvanized steel is coated with a thin layer of oil and passivator that protects it from water and weather damage.
To paint galvanized steel start by applying a latex-based primer evenly across the surface to stop the paint from soaking into it. Here are directions on painting galvanized metal. The secret to painting galvanized steel is white vinegar.

Polish the metal with ammonia and sand any rough areas. Process for Painting Galvanized Steel. Steel is used for many purposes and is also the most corrosive element.
Now be careful not to apply a heavy coating. When metal like iron comes in contact with air and moisture the topmost layers start to corrode due to the metals chemical reaction atmosphere and humidity. The secret weapon of the galvanized steel painting process is.
White vinegar is both effective and non-toxic so it is much safer to use than your average industrial solvent. If hot-dip galvanized steel is going to be painted communication between the fabricator specifier painter and galvanizer is vital before galvanizing. Organic surface contaminants such as oils and some paint are carefully removed from the steel by suitable preliminary treatment usually via a caustic solution.
The following is a quick introduction for the process. Therefore its important to follow the correct procedure when painting galvanized. Like most you probably already have white vinegar on hand as a cleaning solution for your home.

By studying past adhesion failures and successes galvanizers paint companies researchers paint contractors and other sources have created an ASTM specification detailing the process and procedures for preparing hot-dip galvanized steel for painting.
Most low-alloy steel is painted plated or otherwise treated so the steel itself is not exposed to air and moisture. After this passivation the galvanized surface does not need to be painted again which is much cheaper than painting. You see the primer will ensure that the paint fits on smoothly over the surface.
The most common process in doing so would be hot-dip galvanizing wherein the steel would be dipped in molten zinc for it to get covered much like a piece of chicken being breaded before frying. Once the primer has dried apply your first coat of paint with a brush or roller. Let the primer dry completely which should take anywhere from 2-6 hours so your paint will stick properly.
Beside this the zinc content of the galvanized coating reacts with paints binder to create a film that causes the paint to peel source. If you have a kitchen then you probably already have this handy solution. For this step you need a primer.
Clean the surface with warm or hot soapy water. The various parties may desire special handling or require alterations to the design to facilitate the galvanizing process andor the application of paint. Although it is necessary to clean the galvanized surface for painting the zinc layer should remain intact since this is what provides galvanic protection to the steel.
So take your paintbrush dip it into the primer then smudge it across the wall.
