The best for house painting are the HVLP (High volume low pressure) dedicated sprayers. As for electric vs. air, air will give better results, faster with a good compressor. Electric sprayers such as the Wagner power painter are ok for home fixup use, easiert to clean and maintain, cheaper, but will take longer to cover an area and are not as versatile, also they will use more paint. Air sprayers will cover more area faster, especially if you get a siphon feed sprayer that sucks paint right out of the bucket instead of a quart bottle. Air is definitely the way to go painting metal and has more adjustments for painting various coatings.Buying a paint/stain air sprayer, which one is better? Air compressor type or electric type. Pros/cons of each?
Air compressor style is for thin paints and coatings and allows the paint to be atomized, feathered and controlled. It also blows it all over the place which is why paint booths are a good idea. It shoots compressed air through the nozzle and the paint is sucked into the stream and mixed with the air. Used for automotive paints.
For house paints and other thick coatings you need direct pump sprayer that uses a piston pump on the paint to directly force it through the sprayer like a pressure washer. The hand held 'buzz box' sprayers uses an electromagnet and diaphragm or small piston in a similar fashion. It's like squirting a bottle of Windex really fast.
One type of sprayer cannot do both types of paints well.
Hi,
The professionals we sell to buy airless sprayers, they are designed to spray anything from clear oil sealers to heavy bodied acrylic paints. The only thing they need to change is the tip size to accommodate the type of product. On average a piston pump vs a diaphragm will last years even if used on a daily basis. These are the professional models not the Big Box store imitations. $850.00 is an average price for something that will last %26amp; make money for you. Cleaning up %26amp; maintaing is the most important part of making them last.
HVLP sprayers are great for fine finishing ie cabinetry, molding, furniture etc.
Depends if cost is a factor, electric is cheaper and does a good job if you are using air comp. type you will need to have a moisture handler in the line.
Depends on usage - what you are painting.
Cars - Air by a mile
Fences etc etc - Electric ones are fine
Air compressor
Compressed air paint sprayers can save money, offer flexibility, and decrease pollution by using air, rather than aerosol propellants to spray your paint. This technique requires an investment, but for frequent maintenance or shop use, the cost can be well worth it. The unit o tused iis known as a LVLP(low volume, low pressure) sprayer, which applies paint at a lower rate, decreasing airborn paritculates, while applying less paint on each pass.
Spray painting is far more efficient than other methods in certain instances, such as covering large areas with the same color or painting intricate surfaces such as furniture or grillwork, where other tools won't reach all surfaces. It requires some practice in order to handle the equipment and get an even paint covering.
Spray equipment has been available to homeowners for many years, but airless sprayers offer an easier way for do-it-yourselfers to spray paint. Airless sprayers eject paint at high pressure and must be handled carefully to avoid possible injury. An electric airless paint system consists of a paint container, high-pressure pump, motor, handle, and housing and pressure regulator. Extension nozzles, longer suction tubes, extra nozzles and viscosity measuring cup are optional accessories.
Important points to remember in using an airless sprayer, as with other types of sprayers, are proper paint consistency, pressure and tip selection.
Choice of spraying tip depends on paint consistency, but generally the thinner the paint, the smaller the tip needed.
Paint consistency also governs pump pressure. Thinner materials such as stains, lacquers, enamels and sealers require less pressure than heavier materials such as house and wall paint.
Paints formulated for brush or roller application may be too thick for spraying. They should be tested and thinned if necessary.
Other types of spraying equipment have several operational differences.
A suction gun has a vent hole in the cover of the paint cap. A stream of compressed air creates a vacuum, allowing atmospheric pressure to force material from the container to the spray-head. These guns usually are limited to quart-sized containers or smaller and are used where many color changes are necessary.
In a pressure-fed system, the material is force fed to the gun when large amounts of the same color are being used, when materials are too heavy to be siphoned from a cap or container by suction, or when fast application is required.
Non-bleeder sprayers cannot release air until the trigger is pulled. These are used when air is supplied from a tank or from a compressor having pressure control.
A bleeder gun releases air at all times, thus preventing the pressure from building up to a point of popping the safety valve.
Some paint sprayers can be adapted to other uses with proper accessories. For example, an air-gun attachment blows dust from objects to prepare the surface for painting; an adjustable pressure-relief valve regulates maximum air pressure on air guns; an inflater attachment converts the sprayer into a pump to inflate toys, tires, etc.
Another type of applicator in this category is a rotary-disc airless paint sprayer. An auger pump pulls paint from a container mounted under the electrically powered spraying head into a high-speed spinning disc. Centrifugal force from the spinning disc causes the paint to flow through a variable gate opening.
The gate control regulates size of paint swath and eliminates nozzles and high-pressure injection hazards.
High-volume, low-pressure paint sprayers reduce the amount of over-spray typically caused by airless sprayers and conventional, air-powered spray guns. More paint reaches the surface and painters save time and money on paint, drop cloths and masking.

If you use air make sure its a top feed bumb... this helps with the thick and thin paints as will as stain.
