Over the years, it has been amazing how the world of painting has evolved. And not many years I mean.
10 years ago, when you had to paint an aluminum window, for example, you had to do a fairly elaborate treatment to make it look perfect.
However, now, thanks to new products and applications, practically nothing is needed, not even tools.
This does not mean that it cannot be painted by spray or roller like a lifetime. But for relatively small surfaces, it is no longer worth it. Better with sprays.
Of course, not just any spray, they have to be professional and appropriate, like the ones I am going to tell you in this article, where we are going to see how to paint any metal, without tools and with a perfect result.
Below you can see a short video of a couple of minutes or so, with the whole process, and then I will explain it to you in text.
In the video you will see how I paint a large galvanized aluminum industrial lamp. One of the most difficult metals to paint.
But these sprays, the preparation and the application, you can use it on any other metal you want to paint: iron for terrace railings, steel for doors, galvanized steel for extractor hoods, aluminum for doors and windows, galvanized aluminum, copper, nickel , or any other metal that is applied to decoration and construction.
With that said, let’s first look at the necessary materials and then the explanation, and finally, the video.
Materials needed to paint metal without tools:
Medium grit sandpaper sponge. This one goes perfect.
Spray paint (Good quality (TITAN) and the color we want)
And nothing more.
How to paint any metal without tools with a perfect result.
Step One: Sand the Surface.
With the medium-grit sandpaper sponge, we sand the entire surface to be painted, to remove the shine and leave it matte. The entire surface must be nuanced.
Don’t go crazy sanding. Smooth passes that sand the entire surface including any nook, corner or nook.
Second step: Clean the sandpaper dust and apply a basic cleaner with a cloth or paper.
If it is with a rag, better, because some papers release very small cellulose chips and we need the surface to be perfectly clean.
Regarding the cleaner, you can use any of the ones you have at home.
Of course, before applying the primer, which is the next step, you have to make sure that there is no cleaner left on the surface to be painted. That it has dried completely.
Third step. Apply primer:
Now that we have the matted and clean surface, we apply the spray primer.
The primer comes in a spray can, and is usually available in several colors, so that the paint later covers better.
Generally, it is available in white, gray or black.
I use a 4 x 4. Wash Primer which works very well for metal. Which is the one that I have put you above.
We vigorously move the boat for at least a minute.
Then we apply a couple of taps off the surface to see how it pulls and then we prime the surface.
The way to apply it is with the pot vertically and in soft strokes, at a distance of about 25/30 cm. (Then you can see it better in the video).
DO NOT try to load more than you should because you will leak.
Just give it light strokes until it covers.
Once covered, we move on to the next point.
Step Four: Sand the Primer.
With a couple of hours it is more than enough to be able to sand this type of primer, and more considering that it is very fine and that we do not need to sand much, because if we do not eat it.
This is important, you have to sand with a medium / fine grain sponge, and without eating the primer.
Simply give it gentle strokes to remove any impurities that may have stuck to the surface with the primer.
So remember, sand the entire surface but smooth.
Step Five: Clean the Surface.
Now that we have sanded the primer, it’s time to clean the surface of the sandpaper that has remained.
We blow or wipe it off to remove all dust and dirt and we wipe it clean again with the basic cleaner.
Step Six: Spray Paint.
Paint is applied the same as primer.
Shake the paint bottle well first, and make a few test taps on cardboard or another unsuitable surface to see how the paint spills.
Then apply the paint as evenly and evenly as you can.
DO NOT try to overload.
Apply light strokes at a distance of 25/30 cm until you have painted all the metal.
Once the first hand is given, you will probably have to give it a second. Especially if you use dark or very bright colors, such as reds or yellows.
Wait half an hour and apply the second coat in the same way.
Once you finish giving it the second hand, assess if it needs another or if it is already complete.
And that’s it. No more is needed, and the result, in spray, is perfect.
Of course, and this is very important. No matter how well you apply the primer or paint, if the sanding has not been correct, it will be useless. So that both the primer, and therefore the paint, grip well and adhere to the metal surface, it has to be matte, without gloss, completely sanded in all areas.
Another thing that I would like to point out is that although the primer and paint are of good quality, professional, they are still paintings. What I mean by this is that if you pass the tip of a key to the surface, you will grate it, no matter how good the paint is.
Think of the layer of primer and paint left on the metal as microns. That is, thousandths of a millimeter.
And now, here you can see the video where I paint in the way I just explained, a galvanized steel lamp in white, using white primer.
