Graco 18C687 ProSurface Smoothing Blade, 32 in — What It Fits, Where It’s Used & How to Choose

The Graco 18C687 is a 32-inch ProSurface smoothing blade engineered for rapid, glass-like drywall and plaster finishes with minimal sanding. Its INOX stainless, Bi-Flex blade holds more compound on the surface and wears evenly for consistent, low-fatigue passes, while rounded edges help prevent lines and buildup—ideal for wide walls and ceilings in residential, remodel, and commercial interiors.

Where it’s used

• Skim coating large areas and wipe-downs after taping
• Feathering seams and butt joints across open spans
• High-productivity finishing where a paint-ready surface is required

What it fits

Designed for the Graco ProSurface system, this blade mounts to the ProSurface handle and pairs with extendable poles for reach: 20–40 in (18C678) or 40–80 in (18C679). Use 32 in when you need maximum coverage; step down to 10/14/18/24 in sizes for tighter areas.

Key benefits

• INOX Bi-Flex blade technology for smooth finishes and even wear
• Rounded edge profile minimizes edge lines and rework
• Ergonomic control with handle/pole compatibility for long runs

How to confirm it’s the right part

1. Match the part number: 18C687 (32-inch smoothing blade).
2. Select width by task: 32 in for broad, open areas; smaller blades for detail work.
3. Verify compatibility with your ProSurface handle and extension pole setup before ordering.
