At some point, you may be thinking of removing some paint from a metal surface. Maybe the paint is old and you would want to remove it to put a new one. Maybe some paint mistakenly fell on the metal surface, and you want to remove it to maintain homogeneity. At this point, you will be thinking of methods you can use to remove such paints, and a question will pop out in your head, “will a power washer remove paint from a metal surface?” The simple answer is yes.
Getting rid of a paint from a metal surface is challenging. Scrubbing and other manual cleaning methods will only try to get some paint off, but it will take such a long time. Apart from that, it’s very ineffective. You will require something more powerful and efficient to be able to remove paint from metal. Hence, the need for a power washer.
Power washers or pressure washers can quickly blast away paint from a metal surface with ease. All you need is a high PSI, the right type of power washer, and the nozzle to do that. Power washers provide exceptional pressure level and flow rate that is enough to blast away paints. A PSI between 3000 PSI and 4000 PSI, with 6 – 8 GPM is enough to remove paint from a metal surface with ease.
Another reason why you should use a power washer to remove paint from a metal surface is because it’s time-efficient. When it comes to stripping paint from a metal surface, a power washer will do that with relative ease. It will take a power washer a quarter of the time you will use scrubbing with the hand to remove paint. Power washers are great at saving time, paving way for you to focus on other important tasks.
Type of power washer
Generally, power washers can be grouped into two types – the electric power washer and the gas power washer.
Electric power washers are powered by electricity. They are more popular and that’s because they are easy to use and more affordable. Gas power washers operate by the use of gas motors. They are more powerful at stripping off paint and stubborn stains, but they are quite expensive. The pumps generate more pressure and water is discharged at a higher velocity, due to the powerful motors.
You won’t need a powerful washer like the gas for stripping paint. An electric power washer would be enough for that, unless the cost of gas power washers isn’t a major concern to you. Both power washers are good and worth buying if you are considering doing more powerful things than just stripping off paint.
PSI (Pounds-force Per Square Inch)
The efficiency of a power washer is determined by the pressure it exerts, also known as the PSI. The higher the PSI, the more powerful the water discharge is.
Most power washers are able to discharge water as high as 6000 PSI. Some discharge more.
Most power washers include a set of nozzles with some color codes. Each color-coded nozzle is designed for specific purposes.
For removing paint from metal surfaces, you need the yellow-colored nozzle. The yellow nozzle has a 15° spray pattern, which can easily lift off paint from a metal surface with a blast of water. The nozzle also affects the PSI of a power washer.
For removing paint from a metal surface, you will be needing a PSI between 1200 and 3000 PSI. It’s essential that you start with the least setting, and then go further up to avoid damaging the metal itself.
Steps to Remove Paint from Metal Surfaces with a Power Washer
1. Ensure you clean the area that you want to power wash. Also, ensure all windows and doors are closed.
2. Set up the power washer. For additional info, endeavor to read the unit’s manual or give for best connection practices to maximize the efficiency of the machine.
3. Connect the model to its water source. If you are using an electric power washer, plug it to a GFCI outlet. If you are using a gas power washer, ensure there is enough gas in the tank. Overall, make sure the unit is connected and that there are no leaks.
4. Attach the yellow nozzle to the wand of the power washer.
5. Turn the water on. For electric power washers, turn the power on.
6. Hold the wand and aim at the surface at a 45° angle. Stand some meters away from the surface.
7. Pill the trigger and start spraying. Spray with a sweeping motion and avoid spraying on the surface for too long.
8. It’s crucial that you start with less water pressure, and then adjust appropriately as you continue to spray. Also, adjust the position or angle of spray and move closer if you need to exert more water pressure. You may need to power wash for multiple times until you achieve your goal.
9. You will have to wait for a few days to repaint the metal if you want to.
Before using a power washer, you need to make sure that you abide by some safety regulations. A power washer is a powerful tool, and also dangerous if things go the other way. You could end up getting seriously injured in the process.
First of all, wear hand protective gloves and wear something that would cover your body. After that, wear safety goggles to protect your eyes. It’s risky exposing your eyes to a machine like a power washer.
The question, “will a power washer remove paint from metal surfaces” is typically the first question that pops up in the mind of a beginner. Power washers are great equipment that you can use for various cleaning activities, including removing paint from metal surfaces. With the right nozzle, PSI, and some steps, you can successfully remove paint from metal surfaces.
