Contractors and finishers seeking flawless Level 5 results know that not just any paint sprayer will do. When precision, power, and durability matter most, the Graco GMAX II HD stands out as the industry leader for Level 5 finishing and skim coat applications. At Sprayersandparts.com, we stock a full range of Graco GMAX II HD sprayers and factory-grade components that are trusted by pros across the country.
From residential remodelers to commercial drywall finishers, if you demand seamless surface prep and high-output performance, the Graco GMAX II HD offers unbeatable results. Whether you’re pushing joint compound for large ceiling jobs or spraying skim coat over drywall, this high-delivery sprayer is your ultimate job-site partner.
Level 5 drywall finishing is the gold standard for smooth surfaces—and it requires exacting application of skim coat materials. Here’s why the GMAX II HD outperforms competing models:
Engineered for High-Viscosity Materials: Unlike smaller airless units, the GMAX II HD features a robust piston pump system and high-output motor that can handle thick materials like joint compound, texture coatings, and skim coat mixtures without clogging or sputtering.
Consistent Pressure Control: For even film build and flawless coverage, pressure consistency is critical. The GMAX II HD maintains a steady spray pattern that’s ideal for level 5 smooth wall finishes.
Heavy-Duty Construction: From the forged connecting rod to the chrome-plated piston rod, every internal component is designed for job-site punishment.
Time-Saving Design: With fewer clogs and fast cleanup options, the GMAX II HD allows pros to finish large walls and ceilings faster and with less waste.
Whether you’re comparing it to the Graco 7900 sprayer, a Graco 230, or other pro-tier models, the GMAX II HD stands out in terms of torque, flow rate, and reliability.
To keep your GMAX II HD running at peak performance, Sprayersandparts.com offers an unbeatable selection of OEM components and accessories, including:
Pump Repair Kits
Inlet & Outlet Valves
Pressure Controls
Hose Sets
Tip Guards and Spray Tips

Graco RAC X Tips for High Solids
Unlike generic knock-offs, our parts are Graco factory-certified and tested for exact compatibility, durability, and pressure limits. Contractors searching for magnum pro x7 parts, graco truecoat 360 accessories, or skim coat tip options find everything they need—along with clear specs—on each listing page.
When purchasing a professional sprayer, understanding the specifications matters. Here are some of the defining features that make the GMAX II HD a trusted name on demanding drywall and finishing sites:
Max Pressure: 3300 PSI
Max Flow Rate: 2.2 GPM
Motor: Honda® GX 160 or GX 200 Engine
Pump Type: Endurance Chromex™ Piston Pump
Tip Support: Up to 0.045" (ideal for thicker skim coat materials)

Rugged Cart Design: Easy maneuvering across tough terrain
These high-performance specs allow the GMAX II HD to handle both skim coating and high-viscosity painting tasks with ease. From new construction to repair and repaint jobs, this machine is engineered for productivity.

To get the most life from your Graco GMAX II HD, follow these maintenance best practices:
Replace Seals at Regular Intervals: Don't wait for failures. Fresh seal kits and lubricant can extend pump life dramatically.
Use Filtered Materials: Avoid clogs and wear by running pre-filtered or thinned skim coat materials when possible.
Inspect Hose and Gun Fittings: Leaks or degraded seals compromise pressure delivery.
Document Service Intervals: Keep logs of hours used and parts replaced to identify wear patterns.
Stock Common Spares: Keep extra filters, valves, and tips on hand to avoid downtime.
Organize your truck or workshop with labeled bins for accessories like graco magnum x7 replacement spray guns, line striper accessories, or GMAX II HD rebuild kits.
Outfit your rig for maximum versatility with genuine Graco accessories that pair perfectly with your GMAX II HD sprayer:
Graco BlueMax™ II Airless Hoses – Rated for high-pressure, long-run setups
RAC X SwitchTips™ – Ideal for texture, block filler, and skim coat materials
