Keson PA35 Spray-as-You-Walk Paint Applicator

The Keson PA35 is a walk-behind applicator designed for efficient job-site marking. With this tool you can spray while you walk instead of bending over to mark lines from the ground. It holds inverted aerosol paint cans and has a trigger-activated pistol grip so you can stay upright and move steadily while applying consistent, precise spray lines.
This makes the PA35 ideal for long runs of layout marking—on pavement, asphalt, concrete, compacted soil, or turf—where speed, comfort, and line accuracy matter.

• Walk-behind spraying capability: Designed so you can mark as you move, reducing fatigue and increasing productivity compared with bent-over marking.
• Pistol-grip trigger: The trigger is located under a comfortable grip so you can spray precisely when you want.
• Handles inverted-tip aerosol cans: Compatible with standard 15-20 oz inverted marking paint cans
• Front wheel guidance and stable nose: Some models or optional wheels help guide the applicator for cleaner, straighter lines over uneven surfaces.
• Reduced bending and ergonomic ease: Because you stay more upright, it’s easier on your back and legs—especially important on large layout jobs.
• Durable construction: Built for jobsite toughness—enough to handle rough surface walks and frequent use.

• Construction layouts: Marking lines on concrete slabs, asphalt, or compacted surfaces for foundations, paving, or utility corridors.
• Parking lots & site plans: Laying out striping, boundaries, or anchor lines quickly and accurately.
• Landscaping and athletic fields: Marking large areas with consistent width lines—ideal for turf, field edges, or event layouts.
• Utility locates & infrastructure: Precisely marking routes or lines on hard surfaces without needing to crouch or reposition often.
• Long-run marking jobs: Whenever you need to cover a lot of ground with straight, crisp lines while minimizing operator fatigue.
