How do you make galvanized metal look old?
Instead of leaving the metal outside for years to age on its own, speed up the process with vinegar or faux-finish it with paint or glaze. Many types of galvanized metal do not rust, but a patina or a duller finish makes them look weathered or aged.
Want it to happen faster? After burning the finish off, spray or dip the item in a bath of bleach, vinegar or salt water. That will get the oxidization process started. When it's the right amount of rustiness, rinse it off, and let it age out in the weather.
Spray your metal object with plain white vinegar, soaking the surface and letting it dry before reapplying. The acidic vinegar lightly etches the metal surface so the piece will rust faster. Repeat the spray-dry pattern a couple of times.
To make your new, shiny metal appear old, you can antique it with paint. You can also tarnish it using corrosive materials, such as acid cleaner, vinegar, and salt. It may seem like a big project, but all you need is some ordinary household products to make a metal object age several years in just a few hours or so.
Plain white or a primary color can be roughed up with fine-grit sandpaper to give it a weathered look. Antique spray paint can give the appearance of a timely patina in just one coat. Metal spray paint that is evenly sprayed on the shiny surface of a metal piece will give it an immediate look of age and charm.
Galvanizing may be cleaned using a water-based emulsifier, alkaline-based cleaners with a pH of 12 or lower or organic solvents. Then rinse the area with fresh water and simply wipe clean with a soft cloth. Please consult the your galvanizer or the GAA if you have any concerns in regards to cleaning your product.
The secret to painting galvanized steel is white vinegar. White vinegar is both effective and non-toxic, so it is much safer to use than your average industrial solvent. All you have to do is simply apply the vinegar to a clean rag and then wipe down the galvanized surface.
Mix one part vinegar with ten parts water in a bucket. Apply the solution directly onto the metal using a soft cloth or start scrubbing the stain with a soft nylon bristle brush. Other alternatives to white vinegar to get rust off metal surfaces include ammonia, lime juice, and rust dissolver.
Combine 1/2 cup of salt with 1 quart of warm water. Pour the mixture into a spray bottle and shake it until the salt dissolves. Spray this solution all over the outside of the galvanized bucket or tub. This will remove the shiny coating and give it a weathered look.
Add vinegar to your clean, dry container so there is enough to completely submerge the metal. Then add an equal amount of salt to the vinegar, stir it thoroughly, and insert the metal so it can sit in the solution and create a vinegar-salt patina.
The look of copper can be simulated with other metals by using a technique known as a patina. This technique chemically seals the metal with a decorative finish, preventing corrosion. Hot patinas are applied to metals using a propane torch. Aluminum, bronze and iron are excellent metals on which to use a patina.
Set your metal on a baking sheet. Use a heat gun to apply high-powered heat to your metal until it changes color. This method usually works best on such metals as copper, titanium and steel. For example, heat applied to copper can change its brassy orange finish to a dull red, purple or bluish white.
Place silver in a freezer bag with the yolk of a hard-boiled egg to achieve a rich patina. Soak copper in a solution of water and rapid fixer to age the metal. Or, for a blue-green patina, soak it in a mixture of water, vinegar, and salt.
Metal oxidation takes place when an ionic chemical reaction occurs on a metal's surface while oxygen is present. Electrons move from the metal to the oxygen molecules during this process. Negative oxygen ions then generate and enter the metal, leading to the creation of an oxide surface.
Paint a base coat of white acrylic latex paint on the object receiving the rust effect. Sprinkle clean sand over the random areas on the object while the paint is still wet, and allow it to dry for a minimum of 12 hours. Applying sand will give the object the look of oxidation or rough areas where rust forms.
If you have an item made from galvanized metal and you want it to oxidize, you must first remove the zinc coating. This is often done to give galvanized metal an "aged" or "weathered" look. The most common method for removing the zinc from galvanized metal is to use an acid solution to dissolve the zinc.
Wipe the damp cotton ball down the steel from end to end repeatedly until the steel turns black. Repeat the process: keep dipping the cotton into hot vinegar and wipe until the steel color cannot darken any further. Repeat as needed until the steel is uniformly blackened.
Galvanized pipe is coated in a layer of zinc. There are two ways to blacken galvanized pipe: Remove or chemically alter the layer of zinc. Products known as black oxide or steel-blackening kits allow you to change the color of galvanized pipe at home. The pipe must be thoroughly cleaned before using the kit.
Hot black oxide for stainless steel is a mixture of caustic, oxidizing, and sulphur salts. It blackens 300 and 400 series and the precipitation-hardened 17-4 PH stainless steel alloys. The solution can be used on cast iron and mild low-carbon steel.
Distressed metal appears worn, aged and antique. The pristine shine of new sheet metal can sometimes appear to lack character and style. To add vintage appeal to various types of metalwork, you can distress it using fine abrasives like sandpaper and steel wool.
Mix two parts white latex paint and one part tap water to create a whitewash solution, as an alternative, if you do not want to use the old-fashioned whitewash recipe. Using latex paint and water prevents a chalky look to the finish, as well as allowing you to avoid working with lime, a caustic substance.
Place 1 tsp. of metal polish on a cloth and rub it onto the galvanized metal in small circles. Work the polish into the metal to protect it and keep it shiny.
Small Appliances. The plastic and glass surfaces on most small kitchen appliances, such as blenders, coffee makers, and toasters, are safe to clean with vinegar, but you want to avoid any rubber parts or metal that vinegar can corrode. This includes stainless steel.
Mix together baking soda in water, and dip the metal inside the solution for at least 30 minutes. Then, wipe the metal dry with a clean cloth.
