Graco 18C686 ProSurface Smoothing Blade, 24 in — What It Fits, Where It’s Used & How to Choose

The Graco 18C686 is a 24-inch ProSurface smoothing blade designed for a fast, glass-like finish with minimal sanding. Its precision INOX stainless steel, Bi-Flex blade keeps more compound on the surface and wears evenly for consistent passes, while rounded edges help prevent lines and buildup to reduce rework.

Where it’s used

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

What it fits

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 blades included in the ProSurface Drywall Tool Kit (18C676) for an all-in-one finishing setup.

Why choose this width

• 24 in covers wide, open walls and ceilings efficiently
• Bi-Flex INOX blade delivers smooth finishes and even wear
• Rounded edges minimize edge lines and material buildup

How to confirm it’s the right part

1. Match the part number: 18C686 (24-inch smoothing blade).
2. Select width by task: 24 in for large runs; consider 10/14/18 in for tighter areas.
3. Verify compatibility with your ProSurface handle and extension pole setup.
