Tripboba.com - A fresh paint coat will brighten the look and prolong the life of metal surfaces in and around your house. It is no longer difficult to paint metal than to paint other materials.

As in most paint jobs, whether you're painting an antique desk or an outdated yard fence, your success will depend primarily on how much time you put into the planning process.

Read on the instructions on how to paint metal, and you can also find more information on metal paint below!

Paint is a perfect way to retrofit an old piece of metal — whether it's a handrail, chair, or bed frame. Look at these instructions to provide a long-lasting handiwork.

1. When you do not know what kind of metal you are working on, keep a magnet to it. The metal is ferrous and susceptible to rusting if it sticks. So, use a wire brush to clean any rusted spots and then dust with a damp cloth.

If it is galvanized metal (the magnet does not stick), clean it with a detergent solution because the coating typically has oil on it, which keeps the paint from sticking to it.

When there is some dust on the galvanized brass, you should polish it, or wash it. You may also want to remove residual paint, if any, before washing the wall.

2. Coat with a rust-inhibiting primer on any metal to make sure it is designed for use on aluminum (the same goes with your preference of color).

3. Use a brush or a roller to paint according to piece form. In between coats, let the paint dry.

1. Oil-based metal paints are the most durable

When you're painting exterior metal surfaces such as walls, lawn chairs, or backyard grills, and commonly used indoor items such as kitchen cabinets and window frames, opt for oil-based paint.

It is generally more expensive than water-based metal paint (USD 20 to USD 50 per gallon), formulated with pigments, alkydes (synthetic resins) or plant-based oil, and solvent (which emit smelly fumes during application) to cure a rigid coat that repels water and stains and resists dents and scuffs.

Nevertheless, oil metal paint is vulnerable to scratching or chipping, and it often appears to fade with time. So, find a label with built-in protection against fade. 

When you first use an oil-based primer (e.g., Rust-Oleum Clean Metal Primer, USD 8.98 a quarter on Amazon), you can achieve a more consistent finish.

Nevertheless, oil metal paint should be added directly to metal because it does not contain water, and therefore there is no chance of corrosion. Skipping primer will save you time on the paint job, but you'll also wait longer for oil-based paint to dry to the touch (usually 6 to 8 hours).

2. Water-based metal paints offer faster drying and fewer fumes

If painting light and moderately used indoor metal surfaces, consider wall sconces, bed frames, or even guest room night tables, go with acrylic paint based on sunlight.

For less than an hour, acrylic paint, consisting of pigments, acrylic resins, and water, emits fewer contaminants and dries to the touch into a durable surface resistant to scratching, chipping, and fading.

It'll be more vulnerable to dents, scratches, and scuffs, though. Bear in mind that applying water-based metal paint directly to metal will rust it, so before applying an oil-based primer.

3. Spray paint cans offer complete coverage of irregular surfaces

Oil- and water-based metal paints come for spray application in large containers, for use with brushes or rollers, or aerosol bottles.

Big cans can be the most cost-effective choice for painting large, rectangular metal items such as fences and backsplashes, but spray metal paints are more useful for painting smaller surfaces with uneven contours, such as bent patio chair legs, light fixtures or bed frame pillars.

Such metal surfaces can be painted with spray paint more efficiently and with fewer treatments than a brush, so you can also prevent tight brush lines.

Fortunately, though it's not necessarily an enjoyable job, if you have time, experience and the right equipment, scraping paint from metal is entirely workable. And the glittering effects are worth the effort.

Here's how to remove paint from metal:

  1. Prepare the place of operation and wear safety clothing. 
  2. Add stripper to the surface, and wait. 
  3. Clear stains from stripper paint. 
  4. Add spirits to rocks.
