I’m Brad, and I make how-to videos. I do custom painting projects, guitar painting, airbrushing, spray can painting, wood working, and a variety of.

Nearly everyone in the U. Spray paints are convenient and available in a virtually endless array of colors, but they have their disadvantages. Chief among those disadvantages is, for most people, the difficulty in obtaining a uniform, deep finish. We're here to help, so before you get out the Krylon or whatever brand you're using sit back and read how to get excellent results. First, you need to know a little about how spray cans are designed and how the paint inside is mixed.

A spray can is technically known as an "aerosol" device. It consists of a vessel that can withstand significant internal pressure the can ; a spray nozzle that incorporates a what he said before he died device that won't let the pressure out of the can until called for; a tube inside the can that brings the fluid paint to the nozzle; and the two critical elements: pressurized gas usually carbon dioxide and the paint.

Today's spray nozzles are really quite good. They are precision-engineered to provide a reasonably high-quality spray, with consistent droplet sizes. The spray pattern they provide isn't adjustable like air-powered spray guns are, but that isn't why so many people have a hard time getting smooth, shiny results. Those very people would encounter the same problems if they used a spray gun. The reasons good finishes are difficult are: 1 the user isn't how to deal with death of mother properly, and 2 the paint itself is very thin low viscosity.

Reason 2 is impossible to fix. That is, spray paints are heavily thinned more solvent-to-paint content in order for them to be pushed out of the can and turned into an aerosol spray. Thicker paint would require greater gas pressure and a more sophisticated nozzle, hence leading to an air-powered paint gun. The "trick" to getting good results with thinned paint is simply to remember that it is, in fact, thinner and prone to runs.

That means more thin coats. Reason 1 is why we are providing this article. There are many, many wrong ways to apply spray paint, all of which end in poor finishes. People hold the can too close, too far away, too long in one spot, move too fast, move to slow, etc. There are so many wrong ways to do it that we'll just concentrate on techniques to do it right. Let's paint!

But first we must make sure our work piece is ready for painting. It has been sanded, smoothed and primed, then sanded again with fine grit or higher paper. Just before painting we've wiped it again with solvent alcohol or lacquer thinner, using a paper towel.

Once that dried we wiped it with a tack rag to remove dust. Now it's placed on a table or some other surface that allows it to be how to use principal component analysis enough to see clearly during spraying we prefer to hang items from the ceiling joists with string and bent pieces of wire.

Make sure there is plenty of light around the work piece. Now we can start spraying. The proper technique will be presented by listing a series of common mistakes:. Mistake 1 — not shaking the can long enough! Now it's time to shake the paint can, and we do so until the little ball inside rattles, thinking that's long enough. Unfortunately, it usually isn't long enough.

The paint pigments have most likely how to co-parent when separated during storage, so they need quite a bit of agitation to properly mix again.

The can you are using probably says to shake for some number of minutes after the ball starts rattling. Do so. In fact, shake the can for at least three minutes unless you've just used it that day. Test the spray on a piece of cardboard or paper. Mistake 2 — not holding the can the proper distance! Spray can directions tell you how far away from the work piece to hold the nozzle.

That distance is to provide the best spray pattern and most equal distribution of the paint. Test that effect on your cardboard and prove it to yourself. What the manufacturer tells you is true. Spraying too far from the surface puts less of the paint on the surface and the paint can actually dry out before it reaches the surface, leaving a rough texture or dull finish to the paint. Mistake 3 — holding the can directly in front of your face!

You can't possibly see how the paint is "wetting" the surface if the can is spraying directly in front of your eyes.

If you are right-handed, hold the can at chest-height about one foot to the right of your what strength peroxide to bleach hair the reverse if left-handed. As you spray you will be looking at your work piece at a "grazing incidence" angle and will easily see how the spray is falling onto the surface.

Spraying at the distance suggested on the can's label gives you control over the paint and helps prevent excess paint buildup which can lead to runs.

Mistake 4 — not moving at the right speed! Once you can see the "wetting" effect; that is, the paint falls onto the surface and what is the pose method starts to become shiny, it's time to move the can along the surface. Keep it moving at all times and the correct speed is that in which the volume of paint coming out wets the surface.

Moving too fast applies a "dusting" of paint that is too little for the components to "float out" to become a smooth surface. Too slow applies the paint too thick and because it is a thin fluid it will start to run and drip. This is where we started. The jack stand has a smooth surface and is ready to receive the primer. Mistake 5 — not staying parallel to the work surface!

You must move the can parallel to the work surface at all times. Not doing so alters the distance from the nozzle to the surface, creating Mistake 2 again. Practice with the can before actually spraying so you know you can move easily over a large area. Mistake 6 — there's no such thing as "one coat. The idea is that the paint you sprayed 10 minutes ago is still uncured and soft, so the new coat will not only stick well but its solvents will tend to "re-melt" the last coat and allow the finish to create a smoother, flatter surface.

Mistake 7 — Saying "that's good enough" when it's not. There will be incidences when, no matter how well you've applied the paint, it just looks lousy. Dust got in the finish, runs appeared, "orange peel" appeared, or something else affected the outcome. How to get a hotmail com address deal! When that happens, just stop and let the paint dry. Next day, sand everything smooth and put on a couple more coats.

If the project really looks terrible, spread on the stripper and get the work what man likes in a woman back down to bare surface.

Fresh paint comes off very easily and you can re-do the whole thing in short order. Paints are generally made from toxic substances, and their solvents are equally dangerous.

Ventilation and breathing protection are very important. When painting indoors you must make sure you have a good ventilating fan or blower to pull vapors outside. Wear a proper filtration mask that removes organic vapors. If you feel dizzy, nauseated or disoriented while painting, stop and get some fresh air. All Rights Reserved.

Apr 24,  · A bodyshop grade repair accomplished using aerosol spray cans. Using 2K aerosol paint cans you can spray activated products that will provide a great finish. The first thing to realize is that although they are painting with spray paint cans they are actually painting with professionally mixed paint. Each can of color base coat is mixed and placed in a spray paint can at the auto body supply store. Use a piece of cardboard covered with aluminum foil if you don't have a sheet of metal or plastic to practice on. Plan to waste the better part of a can of paint in the process. Shake the can periodically while you paint to keep the materials in proper suspension. Don't forget to invert the can when finished, spraying until all color disappears.

A lot of people are talking about how you can paint your car or large sections of your vehicle with Spray Paint vs commercial grade paint that requires mixing and a professional gun and compressor so we thought we would look at what they are talking about and whether it actually works. The first thing to realize is that although they are painting with spray paint cans they are actually painting with professionally mixed paint.

Each can of color base coat is mixed and placed in a spray paint can at the auto body supply store. Unfortunately base coat is not the same as what you would mix yourself because it is not an activated or hardened paint. It is much better than synthetic enamel found in touch up paint cans you can get at your local auto parts store off a shelf and it is a much better match because it is mixed to match your exact vehicle.

The major drawback of Base Coat in a Spray can is as was said it is not activated but also it is not applied in the same way as a spray gun. The paint is not atomized and you can not tell if the metallics are sitting at the bottom of the can or suspended throughout the mixture before you start painting.

The clear coat that you pick up at an automotive paint store in a spray can is really not the worst option. The reason is the can is a special can that has a small capsule on the bottom that you break to release the hardener. First you can expect that professional grade paint that is applied conventionally with a air compressor and professional paint gun is going to be the best bet for your repairs.

The compressor should be 5hp or better but you can often do smaller jobs with your average compressor that can run air tools if you take your time. Renting a compressor is also an option and I have done this a few times when I first started painting cars.

The main reason that your paint job will be better is the atomization of the paint and the amount of paint that you can apply in a single pass. It is also very even and controlled based on your ability to control the gun.

This means that you can come very close to a factory finish by adjusting your gun and the reducer used in the paint. Without the right application method you will never get your paint to match your original color. If you restrict your use of spray can automotive paint to professionally prepared and also clear with a hardener then you can expect pretty good results. I would not suggest that you try to paint a light gold or brown color or a rich cherry red color with lots of metallics but base colors will come out pretty good and if you are only doing a touch up to a bumper, door handle or molding then you should be fine with a better than it looks damaged repair.

The reason for this is that there is too much paint to apply evenly to make such a large repair. If you are making small repairs to parts that will end up seeing wear anyway then using a professional spray can full of professionally prepared paint is not the worst idea just so you can improve the look of your vehicle.

On the other hand if you are painting an area that is highly visible such as the drivers door then you really need to use professional equipment and paint and it needs to be applied with some care. There actually is a reason that paint jobs cost so much today and that is the talent required to make repairs. Tool Reviews.
