How To Use A Spray Paint Gun And Which Type Is Suitable For You?

We both know paint sprayers can help you get the results you expected because they break the paint up into tiny droplets and these droplets will point towards the part needs coating.

It will save your time as well because a spray gun is a lot faster than a paint brush.

So, in which case should you need a spray gun? If you have to paint hard-to-reach spots on furniture or an ample space, such as walls, large rooms and the exterior of the house, a paint sprayer will be an excellent choice. It is also suitable for painting the ceiling and trim.

However, the more you know about sprayers, the better result you will get. I will take more effort to paint with a sprayer.  Now, we will discuss how to paint with a spray gun effectively.

Preparation

Before painting, make sure you do the preparation work carefully.

Check the temperature

If the air temperature is below 45 degrees or above 75 degrees, using sprayers is not suitable. You should not spray paint under direct sunlight either because the paint will dry very soon and cannot have a good bond.

In contrast, the cold weather makes the paint dry more slowly, thus grabbing dirt or bugs. Also, the paint gun is easy to clog.

Here is one tip to prevent clogs, the top complaint about paint sprayers: always stir the paint well before starting and then use a strainer to remove any debris.

Protect nearby surfaces and furniture

To prevent the mess caused by sprayers, protect adjacent surfaces that you are not going to paint, such as windows, floors, and trim by covering them with drop cloths or plastic sheeting.

Do the same with your furniture. If you cannot move all the furniture out of the room, move it to the middle and cover it with plastic sheeting. The paint droplets will not splatter on your belongings.

Wear protective gears

To protect yourself, remember to wear protective clothing and gears like goggles and a respirator. The working area must be ventilated as well.

If you have finished the preparation, now let’s get started.

Instructions on painting

  • You can try testing with a piece of plywood, a timber offcut, a bit of plasterboard or anything else around you first by practicing moving the paint gun in long and straight strokes. Because sprayers can apply paint quickly, you can get an even coat.

And do not just move your arm while you are painting, move your whole body.

  • Test and adjust the spray equipment until you get the result as you want. If the pattern is too narrow, you can create runs by using more paint to the area.

In contrast, a pattern that is too wide requires more than two passes to get a better coat.

Usually, a pattern has a wide of 8 to 12 inches is sufficient for large surfaces.

  • Hold the gun nozzle perpendicular to the surface. While you are painting, keep the same distance from the gun to the surface, ideally 10 to 12 inches.

Even a slight difference in this distance can change the amount of paint you need to apply. For example, if the nozzle is twice as close to the surface, you need to increase the paint by four times.

  • Even when you move the sprayer back and forth, you have to keep the nozzle perpendicular to the surface.

Everybody tends to swing the gun in an arc. But we advise you not to tilt the sprayer upward or downward; otherwise, the spitting will occur, leading to a rough coat.

  • When you paint, overlap between spaces to prevent light patches or stripes.
  • You should handle the corners and the bulges first and the large and flat areas later. Spray vertically and directly at the corners with quicker speed than usual to avoid overloading the edges.
  • After you complete painting some areas, stop to check if there are light or missed spots. If yes, use a brush or roller instead.

Sometimes, back brushing or back-rolling, which means brushing or rolling in the sprayed-on finish, is an excellent choice resulting in a more even coat.

Back brushing works well on unfinished or previously stained wood, and when applying primers and sealers.

  • Clean your sprayer carefully after you use it. Each sprayer has a guideline to protect you from injecting yourself with the paint.

You should empty the paint container, then fill it with water, lacquer or oil of turpentine and then flush it through the sprayer container. Cleaning the filters, gun and spray tip with the same liquid.

Doing so will make sure that no paint has become dry or stuck in any of these parts. Some products now allow you to connect it with your garden hose for easy cleanup.

Which type of paint sprayers suitable for you?

There are three main types of paint spraying guns: HVLP, airless, and compressed air. Choosing a suitable one depends on the kind of painting and your expertise.

HVLP paint sprayers

HVLP (High Volume Low Pressure) paint sprayers push the paint from the tip of the gun by using a steady amount of air to propel. Thanks to the control of lower pressure, mess and waste will be reduced.

HVLP paint sprayers work well with thinner paints like latex-style paints, delicate surfaces or corners. Industrial HVLP sprayers can also handle more sticky liquids; however, they are more expensive.

Airless paint sprayers

Airless paint sprayers push the paint through the tip of the sprayer with an electric pump while applying extremely high pressure to the paint reservoir.

The airless sprayer is suitable for various paint jobs, such as varnish, lacquer, wood stain, and more pasty liquids like latex house paint.

One thing you should remember! Do not let your skin near the gun tip because it can inject paint into your skin and release the toxic chemical into your body.

Compressed air sprayers

Compressed air systems are probably the most simple to use, so they are perfect for novices or someone who begins to paint. You can also use it in most situations.

There is the only thing to remember – you have to wear eye protectors and a respirator. You do not want to inhale any paint, do you?
