HVLP Spray Systems & Finishing Accessories

Q: How do I thin material for spraying with an HVLP gun?

Use a viscosity cup—like the Earlex Ford 4 Viscosity Cup —to time how long the material takes to drain through the cup's orifice. Compare that to the material manufacturer's recommended viscosity for spraying, then add the appropriate thinner (water for water-based, mineral spirits for oil-based) until the flow time matches.

HVLP Spray Systems & Finishing Accessories for Woodworkers

Brushing a topcoat or stain by hand is perfectly valid—but an HVLP spray system delivers faster, more uniform coverage with fewer brush marks on furniture, cabinets, and millwork. Infinity Tools carries the Earlex HVLP spray system lineup along with the full range of accessories you need to spray, support, and clean up efficiently.

The Earlex 5700 Stationary HVLP Spray System is a well-regarded turbine unit suited to water-based and oil-based finishes, stains, and milk paints. Match it with the correct fluid tip for your material viscosity—thicker products like gel stains require a larger tip opening than thin water-based finishes. A Ford 4 viscosity cup takes the guesswork out of thinning materials to the right consistency before spraying.

Frequently Asked Questions

What spray systems does Infinity Tools carry?

Infinity Tools carries the Earlex 5700 Stationary HVLP Spray System, Earlex fluid tips and needle assemblies for both the 5700 and 6300 models, a spray gun cleaning kit, a Ford 4 viscosity cup, rotating spray tables, drying racks, and a Homeright portable spray booth. See the full spray systems & accessories collection.

What is an HVLP spray system and why is it used for woodworking?

HVLP stands for High Volume, Low Pressure. This type of spray system atomizes finish at low air pressure, which reduces overspray and bounce-back compared to conventional spray guns. The result is better material transfer efficiency, a more uniform coat, and less finish wasted as airborne mist in the shop.

What finishes can I spray with the Earlex 5700 HVLP system?

The Earlex 5700 is compatible with water-based and oil-based stains, water-based and oil-based topcoats, latex paints, and milk paints, provided materials are thinned to the correct viscosity. Use the Earlex Ford 4 viscosity cup to verify consistency before spraying.

How do I thin material for spraying with an HVLP gun?

Use a viscosity cup—like the Earlex Ford 4 Viscosity Cup—to time how long the material takes to drain through the cup's orifice. Compare that to the material manufacturer's recommended viscosity for spraying, then add the appropriate thinner (water for water-based, mineral spirits for oil-based) until the flow time matches.

What is a rotating spray table and why is it useful?

A rotating spray table lets you spin the workpiece 360 degrees during spraying without touching the wet finish surface. This means you can coat all sides and edges of a piece without stopping, moving the project, or creating finger marks in wet material.

Do I need a spray booth when using an HVLP system in a home workshop?

A spray booth isn't strictly required, but it is strongly recommended for controlling overspray and improving ventilation. The Homeright Portable Spray Booth is a compact, folding option suited to smaller workshop spaces and helps contain airborne finish particles.

How do I clean an HVLP spray gun after use?

Flush the gun immediately after spraying by running the appropriate solvent (water for water-based, mineral spirits for oil-based finish) through the system until it runs clear. The Earlex Spray Gun Cleaning Kit includes brushes and picks for cleaning needle passages, air caps, and fluid tips thoroughly.

What fluid tip size should I use for water-based finishes vs. thicker materials like gel stain?

Thin water-based finishes typically spray well through smaller fluid tip openings (around 1.0–1.5mm), while thicker materials like gel stains or latex paints require a larger tip (1.8mm or greater) to atomize properly without sputtering. Consult the material's technical data sheet or your spray gun manufacturer's tip selection chart.

What is the Earlex Steam Generator used for?

The Earlex Steam Generator is used for steam bending wood, not for finishing. It generates steam that is piped into a steam box to make solid wood pliable enough to bend to tight curves without breaking—a traditional technique for chair parts, boat ribs, and curved furniture components.

What stains and topcoats from Infinity Tools can I spray with an HVLP system?

Most General Finishes water-based stains, dye stains, milk paints, and topcoats in our stains, paints & finishes collection are HVLP-sprayable when thinned appropriately. Check individual product data sheets for recommended application methods and thinning ratios.
