Interested in buying a paint gun? We will take all your doubts so that you can make the best possible choice!

Paint guns are very useful artifacts to facilitate and speed up the process of painting walls, furniture and all types of surfaces. They can be used for professional or artistic use. They allow you to get rid of the habit of using a brush or roller.

But, how to choose the ideal? There are a number of different models and specifications that help you choose which one would be best for your purpose. So let’s unravel each of these little details now.

First, the most important

  • They can be used not only for walls and walls, but also (and mainly) for automotive works, artistic works, joinery services, among others. There are models indicated for each of these uses.
  • They can work by gravity (reservoir above the equipment) or by suction (below). The former are more efficient, but cost more.
  • Prices can vary between R $ 40 and R $ 650, with most models being in the range of R $ 150. Pay attention if the chosen one already comes with an air compressor or if you will also need to purchase one.

What is a spray gun and what are its advantages?

A paint gun is used to give speed and agility to the process of painting something. The finish is also often superior. Usually, it uses thinner inks, producing more beautiful results.

It is recommended to use a spray gun on smaller, non-straight surfaces. For example, cars, furniture, sculptures and artistic pieces.

For walls and walls, more experience is needed to replace the good old roller. First-time painters can suffer a lot from waste.

Whether for personal or professional use, time of use and improvement are important. It is also essential to understand the differences between each of the various types of spray guns.

According to experts, the negative points of a paint gun are: the need to understand the paints well, since the wrong viscosity can damage the equipment, and the difficulty in maintenance and cleaning.

Gravity or suction spray gun?

There are two types of spray guns on the market: gravity and suction. The first type has the reservoir above the equipment, the second type below.

In the gravity gun , the paint flows from top to bottom, precisely by the action of gravity. From there, it is sprayed out. In these models, it is often possible to adjust the air flow, the fan opening and the amount of paint used.

In the suction gun, however , it is the presence of air inside the object that causes the ink to be sucked in when the trigger is pulled and exits. The major disadvantage in this type is that the waste is much greater.

It is much more common to find gravity pistols on the market. This is in fact the most efficient type and has become the majority on the shelves.

HVLP or LVLP spray gun?

Within gravity pistols, there is also a division into two types: HVLP, which in Portuguese means High Volume and Low Pressure, and LVLP, Low Volume and Low Pressure.

    • HVLP : These models are most recommended for larger surfaces. It is a system that generates less ink loss to the air, causing no clouds. But this is common in all gravity pistols.
    • LVLP : This system is used in pistols for more detailed work. It fits well with models with very small reservoirs that apply materials such as varnish. The small volume of air and the low pressure help in the manual precision achieved with the artifact.

 

How much does a paint gun cost?

Paint guns usually have wide variations in price. In a quick search, we found models ranging from R $ 40 to R $ 650.

What generates the price variation in these objects is the power, the ability to paint different surfaces and, of course, the brand. There are also some models that bring extra items, such as suitcases and viscosity meters, which can have an influence on the final value.

Not necessarily the most expensive model is the best. Ideally, from this guide, you will be able to understand which one best suits your needs!

Where to buy paint guns?

It is very easy to find your spray gun on the Internet. All major e-commerce sites sell this type of artifact. Our recommendations are the Brazilian Amazon and Mercado Livre, but there are many other great sites, such as Americanas, and Walmart.

Still on the Internet, there are websites specializing in home products that are good options. Dutra Máquinas and Loja do Mecânico offer great varieties.

If your preference is for live shopping, stores specializing in articles for home and construction are great options. Good examples are Telhanorte, C&C, Dicico and many others famous in Brazil.

Purchasing criteria: Factors for comparing spray gun models

In addition to the differences between gravity and suction guns and HVLP and LVLP, many other features interfere with the choice of the ideal spray gun. Let us explain below the importance of each one.

We have separated some items that deserve special attention in this guide:

  • Wattage
  • Nozzle diameter
  • Reservoir capacity
  • Weight
  • Compressor adaptation
  • Ink transfer rate
  • Supported viscosity
  • Extra items

Read each item carefully and get to know everything about spray guns!

Wattage

The power of a spray gun is very important and interferes with its efficiency and working speed. We found models up to 650 W, which would allow less time to be spent on large surfaces.

It is possible to relate the power to the amount of ink dissipated per minute. This leads to easier finishing of certain items and the possibility of carrying out more service in less time. The higher the power, the more suitable is the equipment for professional use.

Nozzle diameter

There are many possible uses you may want for your spray gun. To understand which is the most suitable for you, the most important is the nozzle diameter.

Guns with small nozzles , with a maximum of 1 mm, are indicated for paints with low viscosity. Usually, they relate to jobs that require precision and care. There is dripping of paint in this category, so be careful not to get dirty.

The medium nozzles , between 1 and 1.4 mm, are related to medium viscosity inks, such as those based on solvent. They are ideal for homework, such as painting walls.

The large nozzles , above 1.5 mm, require paints with high viscosity. They are indicated for complex jobs, in large production and scale.

Choose the pistol taking into account the type of paint you want to use and, from there, the diameter of the nozzle.

Reservoir capacity

The reservoirs also vary widely from one model to the other of a spray gun: there are some very small, which can hold about 50 ml, and others that reach more or less 800 ml.

Here, again, you think about the type of work you are going to do to have a choice. If you are going to varnish a small sculpture, you don’t need much. However, for a wall or wall, much more will be needed.

Of course, it is always possible to refill the reservoir, but this will take a lot more work.

Weight

There are some models that are heavier, others much lighter. There are also accessories like straps to attach the pistol to the neck, which improves use. But long-term work calls for lighter objects, for example.

There is also a relationship with the material and care of the work. Imagine again the example of varnishing a small sculpture. A lighter pistol is certainly preferable!

Compressor adaptation

Paint guns need an air compressor to function. You may choose a model that comes with one, it may not.

Otherwise, it will be necessary to have compatibility between gun and compressor. To check the compatibility, it is necessary to pay attention to the air consumption.

This is the amount of air that will be used each time the gun is pulled. If it is below or above, it is unlikely that you will achieve good results with painting.

Ink transfer rate

The ink transfer rate is linked to waste. A pistol that has 60% transfer takes that percentage of what is in its reservoir to the intended surface, while the rest is lost in the air in the shape of a cloud.

The models that have the highest throughput are those that use gravity as a method. Moreover, the HVLP. That is exactly why they are usually more expensive. LVLPs, in turn, are also satisfactory.

In suction spray guns, it is common to waste a lot of paint. Less than half of what is in the reservoir goes to the object, the rest is on the way.

Supported viscosity

As we talked about in the item about the diameter of the nozzles, there are ideal models for paints of different viscosities. Some pistols come with a viscosity meter, thus allowing you to know exactly what is being placed on the equipment.

It is important to pay attention to this because high viscosity paints in unprepared guns can cause irreparable damage.

It doesn’t seem ideal to finish your purchase and be obliged to go to the next one, right?

Extra items

In addition to the viscosity meter, some pistols usually come with other extra items. Nozzles of different diameters, carrying cases, electrical adapter, among others.

This type of addition improves the versatility of the product and, if it does not raise the price too much, can be a determining factor in the choice.
