Double Your Production Rate on Big Open Walls

Job: qualify and use a Hyde 28760 Dual Head Tip Extension on a large, open, flat airless-spray field; preserve a controlled fan, overlap, wet edge, exclusion zone, and coating-system result; then compare accepted production against a representative single-tip baseline without turning Hyde’s claim into a guaranteed job outcome.

Difficulty: qualified Tier-1 airless production work. The operator must already be able to commission the exact airless system, recognize an unacceptable pattern, execute the manufacturer’s pressure-relief procedure, maintain a wet edge, and respond correctly to a suspected injection injury. The dual head increases field width; it does not teach those skills.

Time: determined by surface diagnosis, preparation, containment, the coating system, equipment setup, the test and baseline witness, field geometry, interruptions, cleanup, cure, and release. This guide supplies no productivity rate, labor promise, coat count, or completion schedule.

Hyde’s exact product evidence establishes patented dual-tip technology; two offset tips set 6 inches apart; a combined fan Hyde describes as twice the width of a gun or single-tip extension; a feathered internal overlap or “perfect pass”; fit to “G” thread spray guns; a pump floor of .47 GPM or larger; use of 5 and 6 series tips; aircraft-grade-aluminum construction; and easy-cleaning language.

Understand exactly what the 28760 changes

A conventional airless pass has one fan. The operator places that fan beside the preceding pass and creates every lap by movement and spacing. The 28760 puts two tips on one head. Hyde says they are offset, 6 inches apart, and arranged so the second pattern follows the first with a feathered internal overlap. The resulting combined pass is the tool’s production unit.

That distinction matters. The head supplies the overlap inside each combined pass. It does not supply:

the overlap between one combined pass and the next;

the correct tip selection for the coating;

a stable pump response;

fan squareness, travel, or trigger timing;

masking, cut-in, detail, repair, or cleanup;

acceptable film build, hide, adhesion, texture, sheen, or overspray control.

Hyde’s “double” claim therefore applies most plausibly to repeated field passes on a representative open wall under the manufacturer’s comparison conditions. It does not establish that the entire job—from unloading through release—takes half the time. It also does not establish that every compatible pump, legal 5- or 6-series tip selection, coating, painter, wall, or environment reproduces the result.

The honest operating question is not “Will this double my crew?” It is: On this admitted field, with this accepted coating and system, does the dual head increase accepted area per measured interval without increasing rejects, consumption error, overspray, stoppage, or rework? The baseline and readback sections make that answer observable.

Admit only a surface that earns a doubled field pass

Wall and plane

Walk the whole target under normal and raking light. Map substrate, repairs, joints, corners, openings, columns, services, changes of plane, texture, gloss, contamination, previous coating, and every natural section boundary.

The strongest candidate is a broad plane with long repeatable lanes: an open warehouse wall, corridor field, large interior panel, or similarly uninterrupted exterior field whose coating instructions authorize airless application. “Large” is not a dimension supplied by Hyde. The field earns the tool when the operator can repeat the combined pass for long enough that wider coverage outweighs setup and edge work.

Reject or separate:

cut-in, trim, casings, corners, fixtures, penetrations, signs, and narrow returns;

deep relief, recessed profiles, pronounced texture, open framing, and surfaces that shadow either fan;

frequent plane changes that require a different head orientation;

unstable, contaminated, wet, moving, peeling, or otherwise unaccepted substrate;

any zone that cannot be seen, reached, excluded, contained, and read back under control.

The 28760 is not a steerable AnglePRO® head and not a QuickReach® pole. Do not infer reach, add a pole, combine it with another extension, or promise a working height from the product name or image. If legitimate access or close inspection requires an authorized platform, use that platform.

Coating and substrate system

Do not transfer a setup from another paint, primer, stain, block filler, fireproofing, industrial coating, or wall.

If the coating instructions do not authorize the required airless delivery, or if the equipment makers do not authorize the proposed component chain, the job stops before assembly. A “G” thread statement and .47 GPM minimum do not establish coating compatibility.

Make a representative coating proof before a production decision. It must include the actual substrate condition and finish consequence, not only cardboard. Let it reach the coating maker’s specified evaluation state. A wet fan that looks full is not proof of final hide, adhesion, film, texture, or sheen.

Crew, visibility, and reach

Name one qualified operator who owns the trigger, fan, and stop decision. A two-person cadence may add a hose/material/readback tender when the site plan permits it, but Hyde does not claim that staffing model and this guide does not make two people a universal requirement. The helper remains outside the tip arc and exclusion zone, never touches a live connection, never walks under the fan, and never substitutes shouted confidence for the operator’s own read.

The operator must see both outside edges of the combined pattern, the internal meeting region, the prior wet edge, the hose, the next step, and any approach to the exclusion boundary. If glare, fog, distance, obstruction, color, or lighting hides one of those, stop. A doubled pattern that cannot be read is not production.

Open the equipment gate without inventing fit

The gun is identified by its maker as having the “G” thread connection Hyde names, or Hyde/current manufacturer documentation otherwise confirms the exact fit. The physical thread dimension is not established in the accepted 28760 record; similarity and forced engagement are not evidence.

That floor is necessary, not sufficient: the selected coating and two selected tips may require more delivery than the minimum.

The selected tips belong to the 5 or 6 series Hyde names and are authorized for the exact coating, pump, gun, guards, and intended film. The source does not supply a universal tip number, fan, or paired-tip recipe. Do not assume that any two tips in those series form an approved pair.

Both tip positions carry the required guards and every pressurized component stays within its documented service limit.

Hose condition, filters, fittings, gun, pump, and electrical or engine setup pass their current inspections. No taped thread, altered guard, improvised adapter, leaking swivel, damaged hose, or unidentified component enters the test.

With the system stopped and fully pressure-relieved by its manufacturer’s procedure, assemble only by documented instructions. Check that the 28760 seats without force, both guards are present, tips are correctly retained under their own instructions, and the head can be handled without collision or uncontrolled rotation. The exact loading, torque, orientation, seal, and commissioning procedure are system-specific; none is invented here.

Build the representative baseline before claiming a gain

Hyde’s older demonstration description names a same-painter, same-pump, same-conditions comparison against a traditional single-tip extension and says the dual head reached full wall coverage in half the time.

Create two adjacent or otherwise genuinely comparable field sections.

measured area and geometry;

substrate, preparation, primer, and starting condition;

coating identity, batch or lot, mix/strain state, and measured site conditions required by its instructions;

operator, support role, pump, hose, gun, filter state, and authorized settings;

the coating-authorized single-tip baseline configuration;

the authorized 28760 dual-tip configuration;

masking, access, lighting, hose path, section boundary, and readback position;

the same acceptance criteria for coverage, appearance, film or consumption witness, overspray, and rework.

Change only the delivery configuration needed for the comparison. Do not call two different walls, coatings, operators, pumps, or acceptance standards an A/B test.

Measure two clocks:

Field-application interval: from the same ready-at-boundary state through completion of the section’s initial field readback. This isolates pass production.

Section interval: include configuration-specific setup, interruptions, tip service, movement, correction, and rework until the section meets the same acceptance state. This shows whether a pass advantage survives the actual operating section.

Also record accepted area, material used, stoppages, defects, rejected area, and rework. Calculate accepted production from measured accepted area and the chosen elapsed interval; do not substitute nominal fan width. A faster wet wall that later fails film, hide, adhesion, sheen, overspray, or repair acceptance is not accepted production.

Do not require the first test to reproduce “double.” Outcomes are:

admit: the 28760 improves the relevant measured production result while meeting all acceptance gates;

reject for this job: control, quality, system behavior, geometry, or total section result is worse or unacceptable;

inconclusive: the sections or conditions were not comparable, the measurement failed, or a confounder changed.

Stage exclusion, containment, hose, and communication

Airless coating can enter skin through a tip stream or pinhole leak. The entry may look minor while internal damage is severe; medical literature treats it as a surgical emergency. Keep both guards installed, never point either orifice at a person or body part, never feel for or block a leak, and follow the exact pressure-relief procedure before any fluid-path action. If injection is suspected, obtain emergency treatment immediately, say high-pressure injection injury, and identify the material (Graco — Airless Sprayer Safety; medical review).

The combined fan extends farther sideways than a single pattern. Establish the exclusion and masking from the tested combined pattern, expected bounce and drift, ventilation plan, access path, and surrounding property—not from single-tip habit. Remove occupants, customers, pets, unrelated trades, vehicles, and sensitive contents. This guide supplies no universal PPE or ventilation rate.

Route hose from behind or beside the operator, protected from traffic, pinch points, heat, sharp edges, doors, wheels, and the wet field. Leave enough managed slack for a complete section without tugging the gun or turning the head. The helper, if used, handles hose only from the protected side and outside the fan and swing.

Agree on plain commands before the system is live: ready, spray, hold, stop, pressure relief, emergency. “Stop” belongs to either person and requires an immediate trigger release and safe state. Only the operator authorizes restart after personally confirming exclusion, hose, pattern, wall, and wet-edge state.

Prove both fans low before entering the wall field

Start, prime, filter, and commission the complete system only by its controlling instructions. On a secured disposable test target inside containment, establish the authorized operating state and read:

both exterior fan edges;

the internal feathered meeting region;

symmetry and stability over a complete trigger cycle;

tails, fingers, split, pulse, spit, or uneven delivery;

leakage, vibration, rotation, recoil, and hose pull;

trigger-start and trigger-release deposits.

Do not invent pressure or compensate reflexively.

Then test the actual representative wall section. Confirm that the combined pattern, material use, and dry result satisfy the coating criteria. The 6-inch tip spacing and Hyde’s internal-overlap claim do not establish the required overlap between adjacent combined passes.

Spray the admitted field

Define the section

Reserve cut-in, trim, corners, returns, openings, and changing planes for the separately authorized detail method. Break the 28760 field at real architectural boundaries or at coating-authorized planned stops. Size each section so the crew can preserve the coating’s workable edge without rushing past control.

Start at the far accepted boundary and work toward a clear exit where the hose stays on the protected side. On very broad work, move the material and hose station with completed sections rather than stretching the hose across the operator or wet film.

Establish the cadence

The following is qualified Tier-1 motion, not a numeric Hyde recipe:

Confirm the section, exclusion, hose, lighting, coating state, and shared communication.

Bring the head to the tested relationship with the wall. Hold it square to the plane so both tips work from the same intended geometry.

Establish straight controlled movement before triggering; trigger only onto the authorized target; release before motion stops or the combined fan leaves the target.

Translate the gun parallel to the wall. Do not arc from a planted shoulder: an arc changes distance and facing, loading one side of the combined pattern differently from the other.

Join the next combined pass to the prior live edge using the overlap proven by the actual pattern and coating witness. Do not impose a universal fraction.

Close the planned section coherently, then trigger off, lock as the gun instructions require, and perform the scheduled readback.

In a permitted two-person cadence, the operator never relinquishes the gun mid-section. The helper keeps hose drag out of the pass, stages material and records, watches the far combined edge and containment boundary, and calls stop on a visible fault. The helper does not call travel speed, reach into the field, or touch the head.

Read back while correction remains legitimate

Inspect after the first short pass, after the first adjacent-pass overlap, at every material or section change, after every interruption, and whenever sound, fan, light, or hose behavior changes. Use both straight-on and raking views.

Look for a heavy or light internal seam, bands between combined passes, dry outer edges, runs, sag, holidays, texture or sheen change, excessive fog, bounce, coating beyond containment, and actual material use departing from the coating’s witness. Readback is not a reason to spray blindly at a questionable spot. If the cause is uncertain, stop the section and preserve the evidence.

What goes wrong (and the fix)

One tip clogs or changes while the other continues: release immediately. Do not finish the pass on one live tip and do not approach the stopped tip while the other remains capable of spraying. Apply the gun’s safe state, execute full pressure relief, service only by the system instructions, and retest both fans low before returning to the wall.

Both fans tail, pulse, spit, or weaken: stop. The .47 GPM claim is a minimum fit gate, not proof that this coating and tip configuration is being supplied correctly. Do not increase pressure by habit.

One side is heavy and the other dry: the head may be off-square, movement may be arcing, one tip may be compromised, or the fluid split may not be stable. Return to the low test. Do not compensate by twisting the wrist through the production field.

The internal seam or pass-to-pass band is visible: distinguish the two joins. An internal defect belongs to dual-head pattern or setup diagnosis; a band between combined passes belongs to operator overlap, wet-edge timing, or section planning. Correct the cause before continuing. Do not flood the band.

Wet edge closes: stop at the best defensible boundary. Follow the coating maker’s set, preparation, and recoat process. Extra material sprayed into a tacking edge can create a permanent band; it does not restore the original wet edge.

Run, sag, heavy start, or heavy stop: stop adding coating. Use only the coating-authorized live-film correction, or let the defect reach its specified repair state before flattening and recoating the necessary field. Fix motion or trigger timing before restart.

Overspray, ventilation, visibility, exclusion, hose, or service control fails: release and make the system safe. Do not finish a pass through a person, open boundary, live service uncertainty, blind edge, or snagged hose.

Leak or suspected injection: never touch the leak. Isolate, pressure-relieve, and follow emergency procedure. A suspected injection ends production; the wall waits.

Evaluate the before-and-after result

At the coating’s specified inspection state, adjudicate both baseline and dual-head sections against the same criteria.

accepted versus rejected area;

each timed interval and its defined endpoints;

coating use and required film/coverage witness;

defects, stoppages, corrections, and rework;

crew and equipment configuration;

conditions and any confounder;

final disposition: admit, reject for this job, or inconclusive.

Report the measured ratio or difference only with that protocol and scope attached. “The 28760 improved accepted field-application rate on this wall under these conditions” is a defensible result. “This tool doubles every paint job” is not. If field application improves but masking, configuration, edge work, or cleanup controls the schedule, state that the manufacturer’s field-pass advantage did not translate to a doubled whole-job result.

Cleanup, inspection, and release

Finish at the planned boundary, trigger off, secure the gun, and execute the complete manufacturer pressure-relief procedure. Verify the required zero-energy state before removing a tip, guard, extension, gun, filter, fitting, or hose.

Flush and clean the exact coating/equipment system by mutually compatible instructions. The 28760 has two tip positions and a divided delivery role; verify that both paths, guards, tips, and exterior surfaces reach the required clean and inspected state. Invent none.

Keep injection, ventilation, ignition, and exposure controls active during cleanup.

Inspect the dry or otherwise specified finished field under the same release lighting used for the witness. Resolve bands, misses, sags, overspray, substrate failure, or coating defects only through the coating’s approved correction and recoat process. Reinstate electrical, HVAC, alarms, sprinklers, doors, and other services through their responsible procedures. Remove containment without spreading residue.

No coating schedule, warranty outcome, PPE ensemble, cure interval, or return-to-service time is universal to this guide.

The history footnote

Graco dates its first commercial airless sprayer to the 1958 Hydra-Spray. The 28760’s paired-tip idea is a later production refinement of the same architecture: keep pressure-driven atomization at the tip, then widen the useful pass. See Graco’s company history.
