Graco 18C684 ProSurface Smoothing Blade, 14 in

Graco 18C684 ProSurface Smoothing Blade, 14 in — What It Fits, Where It’s Used & How to Choose

The Graco 18C684 is a 14-inch smoothing blade engineered for fast, glass-like drywall and plaster finishes with minimal sanding. Its INOX stainless steel, Bi-Flex blade holds more compound on the wall, wears evenly for consistent results, and the rounded edges help prevent lines and buildup so you spend less time sanding and reworking.

Where it’s used

• Drywall/plaster finishing: skim coating, wipe-downs after taping, feathering seams and butt joints
• Residential remodels, new construction, and commercial interiors needing a paint-ready surface

What it fits

This blade mounts to the ProSurface handle and pairs with extendable poles for reach—20–40 in (18C678) or 40–80 in (18C679). It’s also one of the standard blade sizes included in the ProSurface Drywall Tool Kit (18C676), making it easy to standardize your setup across tasks.

Key features

• Bi-Flex INOX stainless blade for a superior finish and even wear
• Rounded edge profile to minimize edge lines and material buildup
• Ergonomic handle geometry (with pole compatibility) for smooth, low-fatigue passes

How to confirm it’s the right part

1. Match the part number: 18C684 (14 in smoothing blade).
2. Choose width by task: 14 in for everyday rooms and tighter runs; move up to 18/24 in for wide, open areas.
3. Verify compatibility with your ProSurface handle and extension pole setup before ordering.
