But unfortunately, it's also necessary to remove dirt, rust, and old paint and to ensure an even, well-adhering coat of paint. However, you don't necessarily have to reach for the sandpaper. Practical alternatives include:

Sandblasting

Burning

Paint Stripping

Opinions differ when it comes to applying paint. Some prefer painting with a brush, while others swear by a spray gun. Ultimately, the deciding factor is cost.

With a spray gun, you can apply the paint over a large area, evenly, and quickly. Usually, one application is enough to paint the entire fence. Spraying produces a uniform coat of paint. However, spray guns or spray systems aren't exactly cheap. You'll typically pay between 50 and 150 for one. Besides the high cost of purchasing a paint sprayer, covering it with a tarp is difficult – the fine spray mist spreads quickly and widely over the immediate surroundings.

If you decide to apply paint using a sprayer, always wear a respirator and gloves.
