What Is Airless Paint Sprayer

Table of Contents

An airless sprayer works by pumping paint at a very high pressure, up to 3,000 psi, through a hose and out a tiny hole in the spray gun tip. The tip is designed to break up the paint evenly into a fan-shaped spray pattern of tiny droplets. First, the fine particles of paint don’t all stick to the surface.

What is the difference between an airless and a air paint sprayer?

Air sprayers are different from airless primarily because they have to be connected to an air supply, which usually means a bulky, expensive air compressor. Airless sprayers use pressured streams of paint or stain that do not rely on air flow to force the material out of the sprayer, making them extremely portable.

Is an airless paint sprayer better?

Airless sprayers can also handle thicker paint better than compressed air or high volume low pressure (HVLP) sprayers. All paint sprayers should be handled with care, but be especially mindful with an airless sprayer, which works under very high pressure.

What kind of paint do you use on an airless sprayer?

Choose the Paint for the Sprayer The lower the paint viscosity, or consistency, the better to use in a sprayer. Airless pain sprayers work with oil-based paint or stain. HVLP paint sprayers work with oil-based paint, but thicker paints such as water-based latex can clog the sprayer.

Do airless sprayers use more paint?

Airless paint sprayers are extremely popular, but also tend to waste more paint on average than other types of spray guns. Your run-of-the-mill airless paint sprayer will waste up to 40% of the paint that you use, and even more if you aren’t operating the spray gun properly.

What is the advantage of an airless sprayer?

Speed—airless spraying is faster, thus, more jobs can be completed in less time, using less labor. Airless spraying is up to 10 times faster than brushing or rolling. Quality—airless sprayers produce an even coat of paint on all types of surfaces, leaving a consistent and high quality finish.

What are the 4 types of paint sprayers?

The main options are airless, compressed air, and HVLP. The type you require depends on the kind of job and your level of expertise. What is this? Each type contains a reservoir for your chosen paint, as well as a method of propelling the liquid from the container and through the tip of the sprayer.

Do I need an airless sprayer?

The use of airless paint sprayers is particularly worthwhile in large areas because the advantage of the higher working speed. For a long time, the rule of thumb used to be: use a paint sprayer starting from a 3-room apartment and to paint everything smaller than that roller and brush.

Do airless sprayers create overspray?

An airless paint sprayer uses pressure to deliver paint through a spray gun and through a tip. By forcing the fluid pass the small opening, the coating is atomized (broken apart). However, because it uses high pressures when spraying, a lot of your paint can become overspray.

What is the difference between HVLP and airless sprayer?

In an HVLP (which stands for “high volume, low pressure”), air pumped from an air compressor or turbine atomizes paint. In an airless sprayer, a piston pressurizes the material, which sprays out of an orifice smaller than that found on an HVLP nozzle. The high pressure and tight squeeze shear the paint into particles.

Do professional painters use sprayers?

Professional painters have paint sprayers running into the thousands of dollars. As a do-it-yourselfer, you may choose to start with a simple, less expensive type of paint sprayer often called a cup gun sprayer.

How long can you leave paint in an airless paint sprayer?

Short 3 days – 3 months This is probably the most common storage method for most airless paint sprayers. Most painting professionals and contractors fall into this time span. Fresh, clean mineral spirits is considered a storage fluid for this time span, use it or another pump preserver such as Graco Pump Armor.

How much does 1 gallon of paint cover with a sprayer?

One gallon can of paint will cover up to 400 square feet, which is enough to cover a small room like a bathroom.

Do airless paint sprayers make a mess?

One of the best things about a paint sprayer is its clean application. No more splattering, spills, or worse. It cleanly and gently applies paint on many different surfaces without much mess.

Is spraying better than brushing?

Spraying vs. Spraying covers better and the application is more uniform. Spraying has no brush strokes and offers a more durable satin finish that looks much nicer. Hand brushing a new color may not give you the complete, even coverage you are looking for.

What are the disadvantages of spray painting?

Disadvantages Of Spray Painting Requires experience to avoid drips and runs. Risk of uneven finish. Uses more paint. More laborious clean-up process. Usually completed in one long start-to-finish project. Expensive equipment required.

How do airless spray guns work?

Which is better gravity feed or siphon?

There are many advantages that come with using gravity feed over conventional spray guns. Less air pressure: It is obvious that gravity feed overcomes the limitations of a siphon feed design, since less air pressure is required to atomize the paint, making this type of spray gun more efficient.
