Airless or HVLP: the short answer
Buy an airless sprayer if you paint walls, ceilings, exteriors, fences or new construction: it moves the most paint, sprays latex unthinned, and is what production painters run. Buy an HVLP sprayer if your work is cabinets, doors, trim and furniture, where a softer spray and less overspray matter more than speed. Plenty of painting companies own both.
How each sprayer turns paint into a spray
The EPA's coating rules define the two clearly. Airless spray “relies solely on the fluid pressure of the paint” to atomize it, with no compressed air. HVLP equipment is “designed and operated between 0.1 and 10 pounds per square inch gauge (psig) air atomizing pressure”, measured at the air cap (40 CFR 63.11180).
That difference explains everything else. Paint leaving an airless tip at thousands of psi travels fast, covers fast and bounces back as overspray. Paint carried by a large volume of low-pressure air travels slowly, lands softly and is easier to control, but there is far less of it per minute.
Airless vs HVLP side by side
| Airless | HVLP | |
|---|---|---|
| Atomized by | Fluid pressure through a small tip | High volume of air at ≤10 psig at the cap |
| Output | High: whole rooms and exteriors | Low: doors, cabinets, trim, furniture |
| Thick latex | Sprays it unthinned with the right tip | Often needs thinning to the manual's spec |
| Overspray | More; mask widely | Less bounce-back; easier indoors |
| Finish | Good; very good with fine-finish tips | Very fine, easy to feather |
| Learning curve | Pressure, tip choice, overlap | Air and fluid balance, thinning |
| Main hazard | Injection injury from the high-pressure fluid | Lower pressure, but still solvent and mist |
Which sprayer for which job
| Job | Pick | Why |
|---|---|---|
| Empty house, walls and ceilings | Airless | Speed; back-roll walls for an even texture |
| Exterior siding | Airless | Output and reach; see the vinyl and stucco guides |
| Fences and decks | Airless | Coverage on rough wood; mind the wind |
| Kitchen cabinet doors | HVLP or air-assisted | Smooth enamel, little overspray in the shop |
| Interior doors and trim | Either | HVLP for control; airless fine-finish tip for volume |
| Furniture and built-ins | HVLP | Fine finish on small, detailed pieces |
The surface guides go deeper: spraying kitchen cabinets, vinyl siding and stucco. For fences, the fence paint calculator tells you how much to load.
One cabinet job, two sprayers
Cabinets are where the choice is closest, so it is worth walking through the same job with each tool. Take a kitchen with the doors and drawer fronts removed to a garage and the boxes painted in place.
| Step | Airless (fine-finish tip) | HVLP |
|---|---|---|
| Masking the kitchen | Heavy: overspray travels; mask counters, floors, appliances, openings | Lighter, but still mask everything near the boxes |
| Thinning | Usually none; follow the enamel's label | Often thinned to the gun maker's viscosity spec |
| Doors in the garage | Fast; a rack of doors coats in minutes | Slower passes, very controllable on edges and profiles |
| Boxes in place | Fast but needs careful masking and low pressure | Easier to control in tight spaces |
| Finish | Smooth with the right tip and enamel | Very smooth, easy to feather small areas |
| Cleanup | Flush pump, hose and gun; more paint left in the system | Smaller cup and gun to clean |
The enamel matters as much as the sprayer. The best paint for cabinets guide covers which products level well when sprayed, and cabinet refinishing vs painting covers when paint is the right call at all.
Living with each sprayer
- Airless: more paint stays in the pump and hose, so short jobs waste more. Flush thoroughly after every use and keep spare tips and filters on the truck.
- HVLP: less waste per job and quicker color changes, which suits doors and trim in several colors. Expect to spend time getting viscosity and air settings right for each product.
- Both: read the sprayer's manual for maximum tip size, recommended coatings and cleaning steps, and the coating's label for spray thinning limits.
Choosing an airless tip
On Graco tips, the first digit times two is the fan width in inches and the last two digits are the orifice in thousandths of an inch: a 515 sprays a 10-inch fan through a .015-inch opening, a 517 the same fan through a .017-inch opening for thicker paint. Check the largest tip your pump supports before buying a big one. The paint sprayer guide covers setup, pressure and overlap.
Is spraying worth it at all?
On a furnished, occupied room, masking can take longer than rolling the walls. The spray vs roll comparison works through when a sprayer pays for itself, and the labor cost calculator shows what the time saved is worth.
Airless vs HVLP: common questions
What is the difference between an airless and an HVLP sprayer?
An airless sprayer pumps paint to a very high fluid pressure and forces it through a small tip, which breaks it into a fan of droplets with no compressed air. An HVLP sprayer uses a large volume of air at low pressure, no more than 10 psig at the air cap under the EPA definition, to atomize the paint. Airless is faster and handles thick paint; HVLP is slower but gives finer control and less overspray.
Is HVLP or airless better for kitchen cabinets?
Many painters choose HVLP or air-assisted airless for cabinet doors because the softer, more controllable spray lays down a smooth enamel coat with less overspray in a kitchen. An airless with a fine-finish tip can also do it well, especially on boxes and large runs of doors.
Can you spray latex wall paint with an HVLP sprayer?
Often, but slowly. Many HVLP units need thick latex thinned to the viscosity their manual specifies, and the low output makes whole rooms slow going. For walls, ceilings and exteriors an airless sprayer is the usual tool.
What does the tip number on an airless sprayer mean?
On Graco tips the first digit is half the fan width in inches and the last two digits are the orifice size in thousandths of an inch. A 517 tip sprays a 10-inch fan through a .017-inch opening.
