A flexible two-gun kit that rewards a little setup time

Two guns in one case can either be a gimmick or a genuinely useful kit. In this case, the Hotorda HVLP set lands closer to the latter. After putting both the 1.4 mm and 0.8 mm gravity guns through several projects—wall repainting, a furniture refinish, and some small craft parts—I came away impressed by the finish quality per dollar, with a few caveats around setup, instructions, and storage.

What’s in the box and first impressions

The set includes two gravity guns (0.8 mm with a small cup and 1.4 mm with a larger cup), a locking regulator with a gauge, cleaning brushes, and multi-wrenches, all in a blow-molded case. The needles and nozzles are stainless, and the bodies are lightweight. Both triggers have a smooth pull with a predictable break, and the fan and fluid knobs track cleanly, though they lack the tighter feel of higher-end guns.

The big win is having two distinct sizes. The 1.4 mm paired with the 600 ml cup handles most waterborne and solvent paints, primers (properly reduced), and clears. The 0.8 mm with the 150 ml cup is great for stains, dyes, and precision work on small parts where the larger gun would be clumsy.

The case is handy for transport, but it’s snug. Once you install a quick-connect fitting on the gun, it doesn’t nest nicely in the cutout. I ended up either removing the fitting for storage or reworking the foam.

Setup and ergonomics

Installing the locking regulator on the gun’s handle is straightforward. I used PTFE tape on the threads to prevent leaks and set the regulator where I could read the gauge with the gun upright. The lock ring is a small but appreciated touch—once dialed in, the pressure doesn’t drift.

Balance is good with both guns; even the larger cup doesn’t make the 1.4 mm feel top-heavy when half full. The smaller gun shines in tight spaces and for edging—think chair rungs, table legs, and light fixtures—where a rattle can or a brush would otherwise struggle to lay down an even film.

Control interaction is typical HVLP: fan on the side, fluid on the back, and most guns prefer to be tuned with the trigger fully pulled. On my bench, an initial baseline of 26–28 psi at the gun (with the trigger pulled), fan opened to about three-quarters, and the fluid two turns out from closed produced a consistent 8–10 inch pattern at roughly 6–7 inches off the surface. From there, I fine-tuned for each material.

Spray quality and performance

With properly strained and reduced coatings, the 1.4 mm gun delivered an even, soft-edged fan and a finish that ranged from satin-smooth to a mild orange peel depending on viscosity and technique. On a semi-gloss wall repaint, I got a remarkably uniform finish that was faster and more consistent than rollers, especially around corners and trim. The gun didn’t starve or spatter when the compressor was keeping up.

On furniture, a waterborne enamel laid down nicely after I reduced it within the manufacturer’s range and added a dash of flow additive. The 0.8 mm gun excelled for stains and thin clear coats on small parts—less material on the floor, lighter trigger, and more precise edges. It’s the one I kept reaching for when I didn’t want to mix a large batch or risk overloading a small piece.

Transfer efficiency was respectable. Gravity feed minimizes leftovers in the cup, and the smaller cup saved me from mixing more than needed on detail jobs. This is not a miracle worker—HVLP reduces overspray, it doesn’t eliminate it. I still masked generously and wore a proper respirator. Bounce-back was noticeable on harder surfaces at higher pressure; backing down a few psi and keeping the gun moving helped.

Adjustability and the regulator

There’s enough adjustment here to match most DIY tasks. The fan control allows a round spot to a broad fan without sputter, though the first quarter-turn of adjustment doesn’t change much; the sweet spot lives in the middle of the range. The fluid knob gives predictable reductions. The regulator feels accurate enough for repeatability. Being able to lock it and not bump settings mid-pass matters more than it sounds, especially when you’re learning a new material.

Compressor pairing and materials

HVLP guns can be air-hungry. While this set isn’t the thirstiest I’ve used, you still want a compressor that can supply steady air without cycling frantically. I had the best results with a mid-size unit and a 3/8-inch hose. If you’re running a small pancake compressor, plan on frequent pauses to let it catch up and accept a narrower fan.

As with any spray gun, the material matters. Strain everything. Reduce within the coating maker’s guidelines and note that waterborne products often benefit from a touch of retarder or extender for flow. If your finish looks dry or textured, you’re either too far from the surface, moving too fast, spraying too little material, or running too much air. A few test passes on cardboard can save a lot of sanding.

Cleaning and maintenance

Cleanup is straightforward if you don’t let coatings dry in the gun. I flushed with the appropriate solvent or water, then broke down the nozzle, air cap, and needle to brush away residue. The included cleaning kit is handy, though I preferred using my own correctly sized wrenches to avoid slipping on the flats.

One caution: dry thoroughly. Even with stainless needles and nozzles, moisture left in the passages can lead to corrosion on non-stainless bits and in the cup hardware. After cleaning, I blow air through the gun for a minute, wipe threads, and put a drop of spray-gun lube on the needle packing and trigger pivot. Store cups open so any remaining moisture can evaporate.

Where it falls short

• Instructions are thin. If this is your first HVLP, budget time for a few tutorials and test panels. The manual doesn’t cover cleaning best practices or tuning for different coatings.
• The case isn’t perfectly fitted once you add fittings, and some accessories shift during transport. Functional, but not premium.
• The multi-wrench is a “get you by” tool. It works, but proper wrenches are nicer, especially for stubborn nozzles.
• The adjustment knobs lack the fine, damped feel of pro-grade guns. They work; they’re just not luxurious.
• Expect overspray. HVLP is efficient, but you still need to protect surroundings, particularly indoors.

Who will like this set

If you’re stepping up from rattle cans and brushes or you want a budget-friendly second gun that you’re not afraid to dedicate to a specific coating, the Hotorda set makes a lot of sense. The dual-gun approach covers both broad panels and fine detail work, and the included regulator removes a common extra purchase. It’s also a smart kit for occasional automotive touch-ups, cabinetry, and general finishing where you need control without a professional price tag.

If you spray for a living, or you demand perfect ergonomics and ultra-consistent fan geometry, you’ll notice the compromises. A single high-end gun will outclass these in feel and atomization with difficult coatings. But for the money, this kit gets you very close with some patience in setup.

Practical tips from use

• Start with water or solvent in the cup to test fan shape and delivery before loading paint.
• Baseline: 26–28 psi at the gun (trigger pulled), 50% overlap, 6–8 inches from the surface.
• Open the fan first, then bring in fluid until the coat looks wet and even without runs.
• Strain every mix and label cups so you don’t cross-contaminate materials.
• Clean immediately, blow-dry internals, and oil moving parts lightly.
• Keep separate guns for different families of coatings if you can—especially if you ever plan to spray clear over color.

Recommendation

I recommend the Hotorda HVLP set for DIYers and budget-conscious finishers who want versatile, respectable spraying without spending pro money. The 1.4 mm/0.8 mm combo covers a wide range of tasks, the regulator is genuinely useful, and with proper thinning and tuning, the finish quality is consistently good. You’ll need to supply a capable compressor, practice your setup, and take cleaning seriously. If you can live with basic instructions and a so-so case, the value is strong and the results speak for themselves.
