However, the most frequent purpose of thinning is to allow the paint to flow smoothly through a sprayer. Many dense mediums — such as latexes, chalks, milks, and epoxies — are too thick for lower-powered machines, meaning that dilution is necessary. Always dilute the paint with the same format as the base medium. Hence, water for waterborne paints and with spirits for oil-based liquids. Get it wrong, and the incompatible fluids will remain separate — ruining your coat.
The amount of dilution is the most challenging aspect — it depends on the base medium, the power output of the sprayer, and the nozzle size. Beneath the oil-based and waterborne umbrellas sit a plethora of coverage medium types. Created by lab-dwelling paint boffins, these liquids vary in their function, durability, and finish.
Furthermore, the sprayer you need for these fluids can differ — depending on their viscosity. Primer Available in either water or oil-based formats, primer is the starting medium for many DIY and home-improvement projects — due to its ability to provide a suitable base, indicate imperfections, and cover old paint coats.
Waterborne paints, for example, will soak into fresh wood — leaving a disappointing, thin, and uneven finish — the primer gives you an initial base on which to work, ensuring a perfect coat.
Furthermore, by increasing adhesion, primer prevents chips on metal surfaces such as car bodywork. Giving your material a quick covering of primer allows you to see where the surface is uneven, chipped, or scratched — meaning you can address it with sandpaper and filler. Thirdly, primer acts as a clean slate — covering old and tired paintwork and permitting smooth and even coverage, without the aged medium showing through your new coat.
For a detailed explanation on using primer, and examples of the best sprayers in this category — check out my Priming Guide. An older format of paint that has fallen out of fashion due to the introduction of modern vinyls and enamels — although, it keeps a faithful following among tradition-loving DIYers. Instead, it has a solvent base of either alcohol or mineral spirits — the incorrect reference is due to its shiny and durable finish that mimics that of oils.
Alkyds utilize resin or polyester as the binding ingredient — making them able to withstand some serious hardcore abuse and repel water. Furthermore, due to its powerful binder — you can apply alkyds onto existing latex paint, or onto fresh timber without the use of a primer. The downsides are two-fold. Secondly, the binding polymers can make the paint spatter when used with a spray gun. Hence, while you can use a powerful turbine unit, ideally, go for an airless machine, such as the Graco Project Painter Plus.
Not only does the high-pressure output of these hydraulic sprayers allow the delivery of dense alkyds, but also the continuous, non-fluctuating power prevents spatter and coughing. While there are four main formats of lacquer — acrylic, waterborne, catalyzed, and cellulose — they share a similar thin consistency.
And, although durable, they remain breathable, enabling the base material to flex. Lacquer has become something of an umbrella term for varnishes and shellacs. Strictly speaking, it differs in that it dries via mineral spirit evaporation as opposed to oils. However, the terms are used interchangeably by DIYers and trade pros.
Due to its low viscosity, even the most basic turbine sprayer will have sufficient grunt to propel this medium. For a mirror-like sheen, you need to spray, allow to dry, and then sand. Then repeat. And repeat. And repeat again — leading to an impressive French Polish finish. If you want more information, check out my guide to Lacquer Spraying.
Drying to a durable, hard, and water-resistant finish, enamel paint is often utilized in areas subject to high traffic and finger-touching, model-building, and outdoor surfaces. Meaning that the majority of projects will need to be completed in one session, to prevent painting a wet coat onto dry — which will ruin the finish. You could try applying this medium with a brush or roller — but it would be a disaster. Viscous and highly adhesive, it will show every brushstroke as well as pulling out the bristles.
Take a look at my How-To guide for tips on using enamel paints. The latter is paint which is fired in a kiln, for example, on porcelain crockery. With the siphoning element situated on the top of the gun, the gravity feed sprayer requires much less pressure than other options. The result is extreme precision , no overspray, and a very small cleanup. This type of sprayer is very commonly used for spraying cars , which it truly excels at.
The gravity sprayer first hit the scene in the context of automotive work. It was especially prized for its ability to lay down clear coats of paint. Compressed air paint sprayers are very easy to use. Fill the tank with paint, ensure the area is protected, start the compressor, and pull the trigger. This should be enough to get a jet of paint tht you can use to paint individual items or entire walls.
Some electric sprayers can be as simple, but many of them have dials for pressure levels and other features that make them appear more complicated than they need to be.
Pros Simple to use Cheaper than electric spray guns Work with existing air compressors Cons Prone to overspray May not work with thick paints Use a lot of paint. There are various types of paint sprayer available, but the most and increasingly common variant is that of the electric spray gun.
It can cover a large area in a relatively short space of time. Although it may be prone to overspray if you are inexperienced, once you get the hang of using an electric gun, you will be able to get a uniform coverage that is free from brush strokes.
Pneumatic, or compressed air, sprayers are better for precision and artistic work. Coolant, or antifreeze, is a necessary component of many machines, including cars and other vehicles. It mixes with water to maintain a healthy engine temperature,. Pete Ortiz Last updated: Aug 18 Types of Paint Sprayer Below, we have included details of the five main variants of paint sprayer, including details of the most common uses for each type and their pros and cons.

Painting interior walls Painting fences. The most affordable option Relatively lightweight Can be used on large surfaces. Not suitable for thick paints Low volume means regular refills Not very powerful or quick. Painting cabinets and furniture On a tight budget. Extremely precise Easy to clean up. Not very good for high volume work. Simple to use Cheaper than electric spray guns Work with existing air compressors. Prone to overspray May not work with thick paints Use a lot of paint.
Contents 1 Types of Paint Sprayer 2 1. Compressed Air 9 5. Pete Ortiz. Pete has been working in the trades since high school, where he first developed a passion for woodworking. Over the years, he has developed a keen interest in a wide variety of DIY projects around the home. Equip yourself with a paint sprayer! Heavy-duty air-driven paint sprayers use high-pressure air from an air compressor to atomize paint or stain and provide a fine finish.
Sprayers demand your respect. Use a respirator mask and proper eye protection when spraying, and never spray at a person, animal, or window. Cover or mask off anything in the vicinity of your project, including windows and trim, because vaporized paint gets into everything.
If spraying outside, cover plants and avoid painting on windy days. Boasting a foot-tall flexible hose, this With a simple twist of the air cap, you can spray your chosen finish in a vertical, horizontal, or round spray pattern. This 3. The adjustable air cap unleashes a high volume of air at low pressure to allow more paint to reach surfaces, while the adjustable nozzle allows you to spray on a smooth finish using a vertical, horizontal, or round spray pattern. This professional-grade, pound spray unit features adjustable pressure, a stainless steel piston pump, and a flexible suction tube that lets you spray paint at your preferred rate of flow directly from a one- or five-gallon paint can.
The built-in, wheeled cart helps you haul cans of paint, and the foot flexible hose allows you to spray hard-to-reach surfaces, such as the side of a multi-story house. The Graco is rated for use for up to gallons of paint annually.
