Keson PA35 Spray as You Walk Paint Applicator

Turn long layout lines into a quick, comfortable walk. The Keson PA35 is a lightweight, walk-behind applicator that pairs with inverted marking paint to create clean, consistent lines on pavement, concrete, compacted soil, gravel, and turf. An ergonomic trigger on the handle lets you spray without bending, while the wheel-guided nose and shield keep your marks straight and crisp. Perfect for construction layout, utility locates, parking lots, landscaping beds, athletic fields, and event zones.

Key Features

• Walk-behind efficiency: Mark continuously while moving—no bending or stopping between bursts.
• Inverted-can compatible: Accepts most 15–20 oz inverted marking paints (standard contractor valves).
• Wheel-guided accuracy: Front guide wheels and a low nose keep lines straight and steady over rough ground.
• Overspray control: Integrated shield concentrates the fan pattern close to the surface for sharp edges.
• Ergonomic handle & trigger: Comfortable stance and light pull reduce fatigue on long runs.
• Quick can swaps: Adjustable can collar holds cans snugly and speeds color changes.
• Durable build: Impact-resistant frame and corrosion-resistant hardware for daily jobsite use.
• Multi-surface ready: Concrete, asphalt, compacted soil, gravel, and short turf.
• Easy maintenance: Wipe nozzle area after use; store with cap to keep valves clean.

Q: What paint cans does the PA35 accept?
A: Most standard 15–20 oz inverted marking paint cans with contractor-style valves (e.g., Ultra-Mark and similar).

Q: How do I get straight, crisp lines while walking?
A: Use the dual front guide wheels and keep the nozzle shield close (about 2–6 in standoff). Walk at a steady pace and overlap passes slightly for solid coverage.

Q: The spray is sputtering or uneven—what should I check?
A: Reseat the can in the adjustable collar, wipe the nozzle, and shake vigorously to re-mix. Test a quick burst off to the side to clear the valve before continuing.

Q: Any maintenance tips to extend tool life?
A: After each use, wipe the nozzle and shield, purge briefly to clear the valve, store cans capped, and keep the applicator clean and dry to protect the trigger linkage.
